侧滑2
如下图是侧滑的效果图
实现的功能主要是用ViewDragHelper，用ViewDragHelper来自定义一个侧滑面板来实现侧滑
如下是自定义的侧滑面板

主界面是用继承的FragmentActivity来实现下面3个按钮的点击事件，其中第一个Fragment（TentcentOneFragment）内只有个ListView
当停在侧滑界面时，ListView不能进行上下滑动
TentcentOneFragment的代码和xml布局
package com.demo.sb.mainfram; import com.demo.suibian.R; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ListView; import android.widget.TextView; public class TentcentOneFragment extends Fragment { private ListView mListView; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub return inflater.inflate(R.layout.tentcentonefragment, null, false); } @Override public void onActivityCreated(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onActivityCreated(savedInstanceState); mListView = (ListView) getActivity().findViewById(R.id.lv_one_listview); mListView.setAdapter(new MyListAdapter()); } private int[] con = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 }; private String[] name = { "第一人", "第二人", "第三人", "第四人", "第五人", "第六人", "第七人", "第八人", "第九人", "第十人", "第十一人", "第十二人", "第十三人" }; private class MyListAdapter extends BaseAdapter { @Override public int getCount() { // TODO Auto-generated method stub return name.length; } @Override public String getItem(int arg0) { // TODO Auto-generated method stub return name[arg0]; } @Override public long getItemId(int arg0) { // TODO Auto-generated method stub return arg0; } @Override public View getView(int arg0, View arg1, ViewGroup arg2) { // TODO Auto-generated method stub ViewHolder holder; if (arg1 == null) { arg1 = View.inflate(getActivity(), R.layout.item_onelist, null); holder = new ViewHolder(); holder.tv_name = (TextView) arg1.findViewById(R.id.item_name); holder.tv_fight = (TextView) arg1.findViewById(R.id.item_fight); arg1.setTag(holder); } else { holder = (ViewHolder) arg1.getTag(); } holder.tv_name.setText("名字：" + getItem(arg0)); holder.tv_fight.setText("战斗力：" + con[arg0]); return arg1; } } static class ViewHolder { TextView tv_name; TextView tv_fight; } }

第二个Fragment（TentcentTwoFragment）内只有个ViewPager可以进行左右滑动不过还是有点问题
package com.demo.sb.mainfram; import java.util.ArrayList; import com.demo.suibian.R; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.view.PagerAdapter; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.LinearLayout; public class TentcentTwoFragment extends Fragment { private LinearLayout ll_two_group;// 引导圆点的父控件 private ViewPager mViewPager; private ImageView[] diandian;//ViewPager上的点点 private static final int[] mImageIds = new int[] { R.drawable.c, R.drawable.a, R.drawable.d }; private ArrayList<ImageView> mImageViewList; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub return inflater.inflate(R.layout.tentcenttwofragment, null, false); } @Override public void onActivityCreated(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onActivityCreated(savedInstanceState); initView(); } private void initView() { // TODO Auto-generated method stub mViewPager = (ViewPager) getActivity().findViewById( R.id.vp_tentwo_viewpager); ll_two_group = (LinearLayout) getActivity().findViewById( R.id.ll_two_group); initViewPager(); mViewPager.setAdapter(new GuideAdapter()); mViewPager.setCurrentItem(0); mViewPager.setOnPageChangeListener(new GuidePagerListener()); } private void initViewPager() { // TODO Auto-generated method stub // 初始化引导的3个界面 mImageViewList = new ArrayList<ImageView>(); for (int i = 0; i < mImageIds.length; i++) { ImageView imageView = new ImageView(getActivity()); imageView.setBackgroundResource(mImageIds[i]); mImageViewList.add(imageView); } diandian = new ImageView[mImageIds.length]; for (int i = 0; i < mImageIds.length; i++) { //循环加入点点图片组 diandian[i] = new ImageView(getActivity()); if( i== 0){ diandian[i].setImageResource(R.drawable.point_selecte); }else { diandian[i].setImageResource(R.drawable.point_normal); } diandian[i].setPadding(8, 8, 8, 8); ll_two_group.addView(diandian[i]); } // // 初始化引导页的小圆点 // for (int i = 0; i < mImageIds.length; i++) { // View point = new View(getActivity()); // point.setBackgroundResource(R.drawable.point_normal); // LinearLayout.LayoutParams params = new LinearLayout.LayoutParams( // 10, 10); // if (i > 0) { // params.leftMargin = 10;// 设置圆点的间隔 // } // point.setLayoutParams(params);// 设置圆点的大小 // ll_two_group.addView(point); // } // } class GuideAdapter extends PagerAdapter { @Override public int getCount() { // TODO Auto-generated method stub return mImageIds.length; //return Integer.MAX_VALUE; } @Override public boolean isViewFromObject(View arg0, Object arg1) { // TODO Auto-generated method stub return arg0 == arg1; } @Override public Object instantiateItem(ViewGroup container, int position) { // TODO Auto-generated method stub container.addView(mImageViewList.get(position)); return mImageViewList.get(position); // container.addView(mImageViewList.get(position%mImageViewList.size())); // return mImageViewList.get(position%mImageViewList.size()); } @Override public void destroyItem(ViewGroup container, int position, Object object) { // TODO Auto-generated method stub container.removeView((View) object); //container.removeView(mImageViewList.get(position%mImageViewList.size())); } } /** * ViewPager 的滑动监听 * * @author Administrator * */ class GuidePagerListener implements OnPageChangeListener { // 操作屏幕时发生变化 @Override public void onPageScrollStateChanged(int arg0) { // TODO Auto-generated method stub } // 屏幕滚动过程中不断被调用 @Override public void onPageScrolled(int arg0, float arg1, int arg2) { // TODO Auto-generated method stub // int len = (int) (mPointWidth * arg1) + arg0 * mPointWidth; // System.out.println(len); // // 获取当前红色点的布局参数 // RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) view_two_point // .getLayoutParams(); // params.leftMargin = len;// 设置左边距 // view_two_point.setLayoutParams(params);// 重新给小红点设置布局参数 } // 哪个页面被选中 position就是当前滑动到的页面 @Override public void onPageSelected(int position) { // TODO Auto-generated method stub System.out.println("第几个页面" + position +" "+ position%mImageViewList.size()); for (int i = 0; i < mImageIds.length; i++) { diandian[position].setImageResource(R.drawable.point_selecte); if(i != position){ diandian[i].setImageResource(R.drawable.point_normal); } } } } }

下面是2个工具类
第一个是自定义的线性布局可以当侧滑界面打开时，让ListView不能进行滑动
1 package com.demo.sb.widget; 2 3 import com.demo.sb.widget.DragLayout.Status; 4 5 import android.content.Context; 6 import android.util.AttributeSet; 7 import android.view.MotionEvent; 8 import android.widget.LinearLayout; 9 10 public class MyListLinearLayout extends LinearLayout { 11 12 private DragLayout mDragLayout; 13 public MyListLinearLayout(Context context) { 14 super(context); 15 // TODO Auto-generated constructor stub 16 } 17 18 public MyListLinearLayout(Context context, AttributeSet attrs) { 19 super(context, attrs); 20 // TODO Auto-generated constructor stub 21 } 22 23 // public MyListLinearLayout(Context context, AttributeSet attrs, int defStyle) { 24 // super(context, attrs, defStyle); 25 // // TODO Auto-generated constructor stub 26 // } 27 28 public void setDraglayout(DragLayout mDragLayout){ 29 this.mDragLayout = mDragLayout; 30 } 31 32 @Override 33 public boolean onInterceptTouchEvent(MotionEvent ev) { 34 // TODO Auto-generated method stub 35 if(mDragLayout.getStatus() == Status.Close){ 36 return super.onInterceptTouchEvent(ev); 37 38 }else { 39 return true; 40 } 41 } 42 43 @Override 44 public boolean onTouchEvent(MotionEvent event) { 45 // TODO Auto-generated method stub 46 if(mDragLayout.getStatus() == Status.Close){ 47 return super.onTouchEvent(event); 48 49 }else { 50 if(event.getAction() == MotionEvent.ACTION_UP){ 51 mDragLayout.chose();; 52 } 53 return true; 54 } 55 } 56 }
第二个是dp和px 的转化还有自定义Toast的设置比较常用
1 package com.demo.sb.utils; 2 3 import android.content.Context; 4 import android.widget.Toast; 5 6 public class DensityUtil { 7 8 /** 9 * 根据手机的分辨率从dip的单位转为px(像素) 10 */ 11 public static int dip2px(Context context, float dp) { 12 float density = context.getResources().getDisplayMetrics().density; 13 int px = (int) (dp * density + 0.5f);// 4.9->5 4.4->4 14 return px; 15 } 16 /** 17 * 根据手机的分辨率从px(像素)的单位转化成dip 18 * @param ctx 19 * @param px 20 * @return 21 */ 22 public static float px2dip(Context ctx, int px) { 23 float density = ctx.getResources().getDisplayMetrics().density; 24 float dp = px / (density + 0.5f); 25 26 return dp; 27 } 28 29 /** 30 * 自定义吐司 31 * 32 */ 33 public static Toast mToast; 34 public static void showToast(Context mContext, String msg) { 35 if (mToast == null) { 36 mToast = Toast.makeText(mContext, "", Toast.LENGTH_SHORT); 37 } 38 mToast.setText(msg); 39 mToast.show(); 40 } 41 }
