首先介绍它的activity_main.xml布局:
1.它采用3个RelativeLayout相对布局进行,分别对应标题路径、中间显示图片和底部的菜单栏;
2.底部菜单栏由5个LinearLayout水平布局组成,每一个LinearLayout都由ImageView和TextView组成.
代码如下:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.touchimagetest.MainActivity" tools:ignore="MergeRootFrame" > <!-- 顶部路径 --> <RelativeLayout android:id="@+id/MyLayout_top" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="40dp" android:layout_alignParentTop="true" android:gravity="center"> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="15sp" android:text="显示图片操作" /> </RelativeLayout> <!-- 底部按钮 --> <RelativeLayout android:id="@+id/MyLayout_bottom" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="50dp" android:layout_alignParentBottom="true" android:background="@drawable/image_toolbar_bg" android:gravity="center"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" android:layout_alignParentBottom="true" > <LinearLayout android:id="@+id/layout_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/tab_watch_btn" /> <TextView android:id="@+id/textview_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="查看" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout> <LinearLayout android:id="@+id/layout_increase" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_increase" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/tab_increase_btn" /> <TextView android:id="@+id/textview_increase" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="增强" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout> <LinearLayout android:id="@+id/layout_effect" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_effect" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/tab_effect_btn" /> <TextView android:id="@+id/textview_effect" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="特效" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout> <LinearLayout android:id="@+id/layout_frame" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_frame" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/tab_frame_btn" /> <TextView android:id="@+id/textview_frame" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="相框" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout> <LinearLayout android:id="@+id/layout_person" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_person" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/tab_person_btn" /> <TextView android:id="@+id/textview_person" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="美白" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout> </LinearLayout> </RelativeLayout> <!-- 显示图片 --> <RelativeLayout android:id="@+id/Content_Layout" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_above="@id/MyLayout_bottom" android:layout_below="@id/MyLayout_top" android:background="#EFDFDF" android:gravity="center"> <ImageView android:id="@+id/imageView1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center_horizontal" android:scaleType="matrix" /> </RelativeLayout> </RelativeLayout>此时你需要注意的是为每个LinearLayout中ImageView指定src时并不是原图片,而是drawable中的xml文件,如<ImageView android:id="@+id/image_watch".. />.
同时每个drawable中的xml文件对应每个相应的按钮,上图中effect(效果)、increase(增强)、frame(相框)、watch(查看)、person(美白).其中每个格式基本如下,如tab_watch_btn.xml:
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:drawable="@drawable/image_icon_watch_sel" android:state_selected="true"/> <item android:drawable="@drawable/image_icon_watch_sel" android:state_pressed="true"/> <item android:drawable="@drawable/image_icon_watch_nor"/> </selector>其中state_selected表示"选中"状态,state_pressed表示"点击"效果,而最后的<item android:drawable="@drawable/image_icon_watch_nor"/> 表示默认情况显示图片,原图片如下:
同时设置选中状态"按钮"的背景加黑效果,在drawable中添加selector_tab_background.xml文件:
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:drawable="@drawable/image_home_layout_bg" android:state_pressed="true"/> <item android:drawable="@drawable/image_home_layout_bg" android:state_selected="true"/> </selector>
然后在MainActivity.java中添加自定义变量,主要是LinearLayout(点击它响应事件)和ImageView(切换图标).
//自定义变量 private LinearLayout layoutWatch; //查看图片 private LinearLayout layoutIncrease; //增强图片 private LinearLayout layoutEffect; //图片特效 private LinearLayout layoutFrame; //图片边框 private LinearLayout layoutPerson; //图片美白 private ImageView imageWatch; private ImageView imageIncrease; private ImageView imageEffect; private ImageView imageFrame; private ImageView imagePerson;
然后添加代码如下,该种方法需要在点击按钮中设置其他LinearLayout图标状态为未选择状态,否则会出现点击按钮的效果(即:点击就切换图标一次,我们需要的是点击就状态长显).
//创建活动 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //布局 layoutWatch = (LinearLayout) findViewById(R.id.layout_watch); layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase); layoutEffect = (LinearLayout) findViewById(R.id.layout_effect); layoutFrame = (LinearLayout) findViewById(R.id.layout_frame); layoutPerson = (LinearLayout) findViewById(R.id.layout_person); //图标 imageWatch = (ImageView) findViewById(R.id.image_watch); imageIncrease = (ImageView) findViewById(R.id.image_increase); imageEffect = (ImageView) findViewById(R.id.image_effect); imageFrame = (ImageView) findViewById(R.id.image_frame); imagePerson = (ImageView) findViewById(R.id.image_person); //初始化布局 initView(); //按钮一 监听事件 查看图片 layoutWatch.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //设置背景图片加深 Toast.makeText(MainActivity.this, "点击按钮1", Toast.LENGTH_SHORT).show(); layoutWatch.setBackgroundResource(R.drawable.selector_tab_background); //设置图标选中情况 layoutWatch.setSelected(true); layoutIncrease.setSelected(false); layoutEffect.setSelected(false); layoutFrame.setSelected(false); layoutPerson.setSelected(false); } }); //按钮二 监听事件增强图片 layoutIncrease = (LinearLayout) findViewById(R.id.layout_increase); layoutIncrease.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { layoutIncrease.setBackgroundResource(R.drawable.selector_tab_background); //设置图标选中情况 layoutWatch.setSelected(false); layoutIncrease.setSelected(true); layoutEffect.setSelected(false); layoutFrame.setSelected(false); layoutPerson.setSelected(false); } }); //按钮三 监听事件图片特效 layoutEffect = (LinearLayout) findViewById(R.id.layout_effect); layoutEffect.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //设置背景图片 layoutEffect.setBackgroundResource(R.drawable.selector_tab_background); //设置图标选中情况 layoutWatch.setSelected(false); layoutIncrease.setSelected(false); layoutEffect.setSelected(true); layoutFrame.setSelected(false); layoutPerson.setSelected(false); } }); //按钮四 监听事件图片相框 layoutFrame = (LinearLayout) findViewById(R.id.layout_frame); layoutFrame.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //设置背景图片 layoutFrame.setBackgroundResource(R.drawable.selector_tab_background); //设置图标选中情况 layoutWatch.setSelected(false); layoutIncrease.setSelected(false); layoutEffect.setSelected(false); layoutFrame.setSelected(true); layoutPerson.setSelected(false); } }); //按钮五 监听事件图片美白 layoutPerson = (LinearLayout) findViewById(R.id.layout_person); layoutPerson.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //设置背景图片 layoutPerson.setBackgroundResource(R.drawable.selector_tab_background); //设置图标选中情况 layoutWatch.setSelected(false); layoutIncrease.setSelected(false); layoutEffect.setSelected(false); layoutFrame.setSelected(false); layoutPerson.setSelected(true); } }); } //初始化布局 private void initView() { imageWatch.setImageResource(R.drawable.tab_watch_btn); imageIncrease.setImageResource(R.drawable.tab_increase_btn); imageEffect.setImageResource(R.drawable.tab_effect_btn); imageFrame.setImageResource(R.drawable.tab_frame_btn); imagePerson.setImageResource(R.drawable.tab_person_btn); }
<LinearLayout android:id="@+id/layout_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/image_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="3dp" android:src="@drawable/image_icon_watch_nor" /> <TextView android:id="@+id/textview_watch" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="查看" android:textColor="#ffffff" android:textSize="10sp" /> </LinearLayout>此时它的文件夹结构如下图,drawble没有设置背景加深和加载图标的xml文件:
layoutWatch.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_DOWN) { //按下背景图片 layoutWatch.setBackgroundResource(R.drawable.image_home_layout_bg); layoutIncrease.setBackgroundResource(R.drawable.image_home_layout_no); layoutEffect.setBackgroundResource(R.drawable.image_home_layout_no); layoutFrame.setBackgroundResource(R.drawable.image_home_layout_no); layoutPerson.setBackgroundResource(R.drawable.image_home_layout_no); //设置按钮图片 imageWatch.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_watch_sel)); imageIncrease.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_increase_nor)); imageEffect.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_effect_nor)); imageFrame.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_frame_nor)); imagePerson.setImageDrawable(getResources().getDrawable(R.drawable.image_icon_person_nor)); } return false; } });需要注意的是网上下面这段代码仅实现点击一下图片变换的效果,而如果想要实现长显需要如我上面的所示.还见到一个使用Radio实现该效果,当点击一次时判断是否选中并显示相应图片.而使用FragmentTabHost实现同样效果,我不知其原理~
bottomReturnBtn.setOnTouchListener(new OnTouchListener() { //这段代码仅仅实现点击一次改变图标功能 public boolean onTouch(View v, MotionEvent event) { Button upStepBtn = (Button) v; if(event.getAction() == MotionEvent.ACTION_DOWN){ upStepBtn.setBackgroundResource(R.drawable.bottom_sub_order_btn); }else if(event.getAction() == MotionEvent.ACTION_UP){ upStepBtn.setBackgroundResource(R.drawable.bottom_return_check); finish(); } return false; } });
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="0" android:toXDelta="0" android:fromYDelta="120" android:toYDelta="0" android:duration="500" /> </set>它是出现效果:从菜单栏底部向上弹出,同时添加anim_exit.xml:
<?xml version="1.0" encoding="UTF-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <!-- 透明度消失 --> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="200" /> </set>最后在res/values文件夹styles.xml中添加动画效果,通过调用name="AnimationPreview"可以实现动画:
<!-- 定义popupwindows动画效果 --> <style name="AnimationPreview"> <item name="android:windowEnterAnimation">@anim/anim_entry</item> <item name="android:windowExitAnimation">@anim/anim_exit</item> </style>然后你需要自定义弹出PopupWindow的布局xml文件,如popup_effect.xml:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:background="@drawable/image_button_bg_left" android:orientation="vertical" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="5dp" android:orientation="horizontal" > <LinearLayout android:id="@+id/layout_effect_hj" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="2dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:src="@drawable/image_effect_hj" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:shadowColor="#ff000000" android:shadowDx="1.0" android:shadowDy="1.0" android:shadowRadius="1.0" android:text="怀旧" android:textColor="#ffffffff" android:textSize="13.0dip" /> </LinearLayout> <LinearLayout android:id="@+id/layout_effect_fd" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="2dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:src="@drawable/image_effect_fd" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:shadowColor="#ff000000" android:shadowDx="1.0" android:shadowDy="1.0" android:shadowRadius="1.0" android:text="浮雕" android:textColor="#ffffffff" android:textSize="13.0dip" /> </LinearLayout> <LinearLayout android:id="@+id/layout_effect_gz" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="2dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:src="@drawable/image_effect_gz" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:shadowColor="#ff000000" android:shadowDx="1.0" android:shadowDy="1.0" android:shadowRadius="1.0" android:text="光照" android:textColor="#ffffffff" android:textSize="13.0dip" /> </LinearLayout> <LinearLayout android:id="@+id/layout_effect_sm" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="2dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:src="@drawable/image_effect_sm" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:shadowColor="#ff000000" android:shadowDx="1.0" android:shadowDy="1.0" android:shadowRadius="1.0" android:text="素描" android:textColor="#ffffffff" android:textSize="13.0dip" /> </LinearLayout> <LinearLayout android:id="@+id/layout_effect" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="2dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:src="@drawable/image_effect" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="1.0dip" android:shadowColor="#ff000000" android:shadowDx="1.0" android:shadowDy="1.0" android:shadowRadius="1.0" android:text="锐化" android:textColor="#ffffffff" android:textSize="13.0dip" /> </LinearLayout> </LinearLayout> </LinearLayout> </RelativeLayout>它的在Xml中Graphical Layout显示效果如下图所示:
//弹出按钮 private PopupWindow popupWindow1; private PopupWindow popupWindow2; private PopupWindow popupWindow3; private PopupWindow popupWindow4; private PopupWindow popupWindow5;然后当点击"相框"布局LinearLayout时,添加代码如下(其他类似):
//按钮四 监听事件图片相框 layoutFrame.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //载入PopupWindow if (popupWindow4 != null&&popupWindow4.isShowing()) { popupWindow4.dismiss(); return; } else { initmPopupWindowView(4); //number=4 int[] location = new int[2]; v.getLocationOnScreen(location); Toast.makeText(MainActivity.this, ""+location[0], Toast.LENGTH_SHORT).show(); popupWindow4.showAtLocation(v, Gravity.NO_GRAVITY, location[0], location[1]-popupWindow4.getHeight()); } } });其中initmPopupWindowView(int number)为自定义函数,参数对应的是点击LinearLayout的序号,点击"按钮"4即传入数字4:
public void initmPopupWindowView(int number) { View customView = null; // 获取自定义布局文件 if(number==1) { //查看 customView = getLayoutInflater().inflate(R.layout.popup_watch, null, false); // 创建PopupWindow实例 (250,180)分别是宽度和高度 popupWindow1 = new PopupWindow(customView, 250, 280); // 设置动画效果 [R.style.AnimationFade 是自己事先定义好的] popupWindow1.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow1 != null && popupWindow1.isShowing()) { popupWindow1.dismiss(); popupWindow1 = null; } return false; } }); } if(number==2) { //增强 customView = getLayoutInflater().inflate(R.layout.popup_increase, null, false); popupWindow2 = new PopupWindow(customView, 450, 150); // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法 popupWindow2.setFocusable(true); // 设置允许在外点击消失 popupWindow2.setOutsideTouchable(true); popupWindow2.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow2 != null && popupWindow2.isShowing()) { popupWindow2.dismiss(); popupWindow2 = null; } return false; } }); } if(number==3) { //效果 customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false); popupWindow3 = new PopupWindow(customView, 450, 150); // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法 popupWindow3.setFocusable(true); // 设置允许在外点击消失 popupWindow3.setOutsideTouchable(true); popupWindow3.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow3 != null && popupWindow3.isShowing()) { popupWindow3.dismiss(); popupWindow3 = null; } return false; } }); } if(number==4) { customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false); popupWindow4 = new PopupWindow(customView, 450, 150); // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法 popupWindow4.setFocusable(true); popupWindow4.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow4 != null && popupWindow4.isShowing()) { popupWindow4.dismiss(); popupWindow4 = null; } return false; } }); } if(number==5) { customView = getLayoutInflater().inflate(R.layout.popup_frame, null, false); popupWindow5 = new PopupWindow(customView, 450, 150); // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法 popupWindow5.setFocusable(true); popupWindow5.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow5 != null && popupWindow5.isShowing()) { popupWindow5.dismiss(); popupWindow5 = null; } return false; } }); } //end if }
if(number==3) { //效果 customView = getLayoutInflater().inflate(R.layout.popup_effect, null, false); popupWindow3 = new PopupWindow(customView, 450, 150); // 使其聚集 要想监听菜单里控件的事件就必须要调用此方法 popupWindow3.setFocusable(true); // 设置允许在外点击消失 popupWindow3.setOutsideTouchable(true); popupWindow3.setAnimationStyle(R.style.AnimationPreview); // 自定义view添加触摸事件 customView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (popupWindow3 != null && popupWindow3.isShowing()) { popupWindow3.dismiss(); popupWindow3 = null; } return false; } }); //判断点击子菜单不同按钮实现不同功能 LinearLayout layoutEffect1 = (LinearLayout) customView.findViewById(R.id.layout_effect_hj); layoutEffect1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "效果-怀旧", Toast.LENGTH_SHORT).show(); } }); LinearLayout layoutEffect2 = (LinearLayout) customView.findViewById(R.id.layout_effect_fd); layoutEffect2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "效果-浮雕", Toast.LENGTH_SHORT).show(); } }); LinearLayout layoutEffect3 = (LinearLayout) customView.findViewById(R.id.layout_effect_gz); layoutEffect3.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "效果-光照", Toast.LENGTH_SHORT).show(); } }); LinearLayout layoutEffect4 = (LinearLayout) customView.findViewById(R.id.layout_effect_sm); layoutEffect4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "效果-素描", Toast.LENGTH_SHORT).show(); //打开图片 OpenImage(); } }); LinearLayout layoutEffect5 = (LinearLayout) customView.findViewById(R.id.layout_effect); layoutEffect5.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "效果-锐化", Toast.LENGTH_SHORT).show(); } }); }
