最终的效果图
二、Demo项目结构
核心文件是TabView.java和attrs.xml文件,其它都是次要的。只需要将sms.edward.per.myapplication包下的TabView文件和values文件夹下的attrs.xml文件复制到自己的工程项目即可使用。
三、TabView控件的使用方法
(1)4行核心代码调起Tab选项卡
/**
* description:
* <p>
* author:Edward
* <p>
* 2015/11/8
*/
public class one extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.one);
//调起Tab的核心代码如下
String[] tabTitle = {"首页", "我", "搜索"};
TabView tabView = (TabView) findViewById(R.id.tab_view);
//设置tab标题
tabView.setTabTitle(tabTitle);
tabView.setFragments(this, getFragment(tabTitle));
}
public Fragment[] getFragment(String[] tabTitle) {
Fragment[] fragments = new Fragment[tabTitle.length];
for (int i = 0; i < tabTitle.length; i++) {
Fragment fragment = new MyFragment();
Bundle bundle = new Bundle();
//设置参数,传递给Fragment页面
bundle.putString("my", String.valueOf(i + 1));
fragment.setArguments(bundle);
fragments[i] = fragment;
}
return fragments;
}
}
XML布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<sms.edward.per.myapplication.TabView
android:id="@+id/tab_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
(2)显示图标和标题
/**

* <p>
* 2015/11/8
*/
public class two extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.two);
int[] selectedTabImg = {R.mipmap.aty_main_home, R.mipmap.aty_main_centre, R.mipmap.ic_search_blue};
int[] selectTabImg = {R.mipmap.aty_main_home_c, R.mipmap.aty_main_centre_c, R.mipmap.ic_search_black};
String[] tabTitle = {"首页", "我", "搜索"};
TabView tabView = (TabView) findViewById(R.id.tab_view);
//设置tab标题
tabView.setTabTitle(tabTitle);
//设置没有被选中的图标状态
tabView.setSelectTabImg(selectTabImg);
//设置被选中的图标状态
tabView.setSelectedTabImg(selectedTabImg);
//此处的setFragments必须最后才调用,否则上面的设置都无效
tabView.setFragments(this, getFragment(tabTitle));
}
public Fragment[] getFragment(String[] tabTitle) {
Fragment[] fragments = new Fragment[tabTitle.length];
for (int i = 0; i < tabTitle.length; i++) {
Fragment fragment = new MyFragment();
Bundle bundle = new Bundle();
//设置参数,传递给Fragment页面
bundle.putString("my", String.valueOf(i + 1));
fragment.setArguments(bundle);
fragments[i] = fragment;
}
return fragments;
}
}
布局文件和(1)相同
(3)tab放在顶部,禁止滑动,隐藏图标
/**

* <p>
* author:Edward
* <p>
* 2015/11/8
*/
public class three extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.three);
int[] selectedTabImg = {R.mipmap.aty_main_home, R.mipmap.aty_main_centre, R.mipmap.ic_search_blue};
int[] selectTabImg = {R.mipmap.aty_main_home_c, R.mipmap.aty_main_centre_c, R.mipmap.ic_search_black};
String[] tabTitle = {"首页", "我", "搜索"};
TabView tabView = (TabView) findViewById(R.id.tab_view);
//设置tab标题
tabView.setTabTitle(tabTitle);
//设置没有被选中的图标状态
tabView.setSelectTabImg(selectTabImg);
//设置被选中的图标状态
tabView.setSelectedTabImg(selectedTabImg);
//只显示标题,有三个可选址SHOW_TITLE,SHOW_ICON,SHOW_ICON_AND_TITLE
tabView.setIsShowIconTitle(TabView.SHOW_TITLE);
//设置tab到顶部,只有TabView.TAB_LOCATION_TOP,TabView.TAB_LOCATION_BOTTOM可选
tabView.setTabLocation(TabView.TAB_LOCATION_TOP);
//设置tab整个栏的高度
tabView.setTabHeight(30);
//禁止ViewPager滚动,true表示可滑动,false表示不可滑动
tabView.setIsViewPagerScrollable(false);
//此处的setFragments必须最后才调用,否则上面的设置都无效
tabView.setFragments(this, getFragment(tabTitle));
}
public Fragment[] getFragment(String[] tabTitle) {
Fragment[] fragments = new Fragment[tabTitle.length];
for (int i = 0; i < tabTitle.length; i++) {
Fragment fragment = new MyFragment();
Bundle bundle = new Bundle();
//设置参数,传递给Fragment页面
bundle.putString("my", String.valueOf(i + 1));
fragment.setArguments(bundle);
fragments[i] = fragment;
}
return fragments;
}
}
布局文件和(1)相同
(4)设置tab的点击颜色
/**
* description:
* <p>
* author:Edward
* <p>
* 2015/11/8
*/
public class four extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.four);
int[] selectedTabImg = {R.mipmap.aty_main_home, R.mipmap.aty_main_centre, R.mipmap.ic_search_blue};
int[] selectTabImg = {R.mipmap.aty_main_home_c, R.mipmap.aty_main_centre_c, R.mipmap.ic_search_black};
String[] tabTitle = {"首页", "我", "搜索"};
TabView tabView = (TabView) findViewById(R.id.tab_view);
//设置tab标题
tabView.setTabTitle(tabTitle);
//设置没有被选中的图标状态
tabView.setSelectTabImg(selectTabImg);
//设置被选中的图标状态
tabView.setSelectedTabImg(selectedTabImg);
//设置未选择tab的背景颜色
tabView.setTabSelectBackgroundColorId(Color.parseColor("#DFEDDE"));
//设置选择tab的背景颜色
tabView.setTabSelectedBackgroundColorId(Color.parseColor("#0CAA60"));
//设置未选择tab标题的颜色
tabView.setSelectTextViewColorId(Color.parseColor("#858787"));
//设置选择tab标题的颜色
tabView.setSelectedTextViewColorId(Color.parseColor("#ffffff"));
//此处的setFragments必须最后才调用,否则上面的设置都无效
tabView.setFragments(this, getFragment(tabTitle));
}
public Fragment[] getFragment(String[] tabTitle) {
Fragment[] fragments = new Fragment[tabTitle.length];
for (int i = 0; i < tabTitle.length; i++) {
Fragment fragment = new MyFragment();
Bundle bundle = new Bundle();
//设置参数,传递给Fragment页面
bundle.putString("my", String.valueOf(i + 1));
fragment.setArguments(bundle);
fragments[i] = fragment;
}
return fragments;
}
}
布局文件和(1)相同
(5)XML属性设置
/**
* description:
* <p>
* author:Edward
* <p>
* 2015/11/8
*/
public class five extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.five);
int[] selectedTabImg = {R.mipmap.aty_main_home, R.mipmap.aty_main_centre, R.mipmap.ic_search_blue};
int[] selectTabImg = {R.mipmap.aty_main_home_c, R.mipmap.aty_main_centre_c, R.mipmap.ic_search_black};
String[] tabTitle = {"首页", "我", "搜索"};
TabView tabView = (TabView) findViewById(R.id.tab_view);
//设置tab标题
tabView.setTabTitle(tabTitle);
//设置没有被选中的图标状态
tabView.setSelectTabImg(selectTabImg);
//设置被选中的图标状态
tabView.setSelectedTabImg(selectedTabImg);
//此处的setFragments必须最后才调用,否则上面的设置都无效
tabView.setFragments(this, getFragment(tabTitle));
}
public Fragment[] getFragment(String[] tabTitle) {
Fragment[] fragments = new Fragment[tabTitle.length];
for (int i = 0; i < tabTitle.length; i++) {
Fragment fragment = new MyFragment();
Bundle bundle = new Bundle();
//设置参数,传递给Fragment页面
bundle.putString("my", String.valueOf(i + 1));
fragment.setArguments(bundle);
fragments[i] = fragment;
}
return fragments;
}
}
Xml布局代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:test="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<sms.edward.per.myapplication.TabView
android:id="@+id/tab_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
test:tv_Tab_Location="TAB_LOCATION_TOP"
test:tv_Tab_Show_Cursor="true"
test:tv_Tab_Transverse_Line_Height="2dp"
test:tv_Tab_Show_Icon_Title="SHOW_ICON"
test:tv_Tab_Selected_Background_Color="@color/red"
test:tv_Tab_Title_Size="18dp"
test:tv_Tab_Height="30dp"/>
</LinearLayout>
四、自定义TabView控件的所有可设置方法
(1)java代码可设置的方法
//设置tab标题
tabView.setTabTitle(tabTitle);
//设置没有被选中的图标状态
tabView.setSelectTabImg(selectTabImg);
//设置被选中的图标状态
tabView.setSelectedTabImg(selectedTabImg);
//设置图标与文本的间隔
tabView.setIconAndTextSpace(5);
//设置未选择tab的背景颜色
tabView.setTabSelectBackgroundColorId(Color.parseColor("#DFEDDE"));
//设置选择tab的背景颜色
tabView.setTabSelectedBackgroundColorId(Color.parseColor("#0CAA60"));
//设置未选择tab标题的颜色
tabView.setSelectTextViewColorId(Color.parseColor("#858787"));
//设置选择tab标题的颜色
tabView.setSelectedTextViewColorId(Color.parseColor("#ffffff"));
//设置图片的宽度和高度
tabView.setImgWidthAndHeight(30, 30);
//设置tab到顶部,有两个可选值TAB_LOCATION_TOP,TAB_LOCATION_BOTTOM
tabView.setTabLocation(TabView.TAB_LOCATION_TOP);
//是否显示游标
tabView.setIsShowCursor(true);
//设置游标颜色
tabView.setCursorBackgroundColorId(Color.RED);
//只显示标题,有三个可选址SHOW_TITLE,SHOW_ICON,SHOW_ICON_AND_TITLE
tabView.setIsShowIconTitle(TabView.SHOW_ICON_AND_TITLE);
//禁止ViewPager滚动,true表示可滑动,false表示不可滑动
tabView.setIsViewPagerScrollable(false);
//设置字体大小
tabView.setTextSize(12);
//设置tab整个栏的高度
tabView.setTabHeight(60);
//设置分割线颜色
tabView.setTabTransverseLineColor(Color.parseColor("#ffbdc0c3"));
//设置分割线高度
tabView.setTabTransverseLineHeight(3);
五、源代码
(1)TabView.java源代码
为了减少XML文件的依赖,没有用XML文件来设置布局,基本上都是使用代码的方式来设置。所以代码量可能有点多。
