自定义PopupWindow弹出框（带有动画）

使用PopupWindow来实现弹出框，并且带有动画效果

首先自定义PopupWindow

 public class LostPopupWindow extends PopupWindow {
     public Lost lost;
     public void onLost(Lost lost){
         this.lost = lost;
     }
     private View conentView;

     public View getConentView() {
         return conentView;
     }

     public LostPopupWindow(final Activity context) {
         LayoutInflater inflater = (LayoutInflater) context
                 .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         conentView = inflater.inflate(R.layout.lost_pop_menu, null);
         int h = context.getWindowManager().getDefaultDisplay().getHeight();
         int w = context.getWindowManager().getDefaultDisplay().getWidth();
         // 设置SelectPicPopupWindow的View
         this.setContentView(conentView);
         // 设置SelectPicPopupWindow弹出窗体的宽
         this.setWidth(w / 2 + 50);
         // 设置SelectPicPopupWindow弹出窗体的高
         this.setHeight(LayoutParams.WRAP_CONTENT);
         // 设置SelectPicPopupWindow弹出窗体可点击
         this.setFocusable(true);
         this.setOutsideTouchable(true);
         // 刷新状态
         this.update();
         // 实例化一个ColorDrawable颜色为半透明
         ColorDrawable dw = new ColorDrawable(0000000000);
         // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作
         this.setBackgroundDrawable(dw);
         // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
         // 设置SelectPicPopupWindow弹出窗体动画效果
         this.setAnimationStyle(R.style.AnimationPreview);
         LinearLayout send = (LinearLayout) conentView
                 .findViewById(R.id.send);
         LinearLayout mySend = (LinearLayout) conentView
                 .findViewById(R.id.my_send);
         LinearLayout all = (LinearLayout) conentView.findViewById(R.id.all);
         send.setOnClickListener(new View.OnClickListener() {

             @Override
             public void onClick(View arg0) {
                 LostPopupWindow.this.dismiss();
                 lost.onLost(2);
             }
         });

         mySend.setOnClickListener(new View.OnClickListener() {

             @Override
             public void onClick(View v) {
                 LostPopupWindow.this.dismiss();
                 lost.onLost(1);
             }
         });

         all.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 LostPopupWindow.this.dismiss();
                 lost.onLost(0);
             }
         });
     }

     /**
      * 显示popupWindow
      *
      * @param parent
      */
     public void showPopupWindow(View parent) {
         if (!this.isShowing()) {
             // 以下拉方式显示popupwindow
             this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);
         } else {
             this.dismiss();
         }
     }

 }

R.layout.lost_pop_menu文件

动画R.style.AnimationPreview

  <style name="AnimationPreview">
         <item name="android:windowEnterAnimation">@anim/fade_in</item>
         <item name="android:windowExitAnimation">@anim/fade_out</item>
     </style>

 @anim/fade_in

 <?xml version="1.0" encoding="utf-8"?>
 <!-- 左上角扩大-->
 <scale   xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/accelerate_decelerate_interpolator"
     android:fromXScale="0.001"
     android:toXScale="1.0"
     android:fromYScale="0.001"
     android:toYScale="1.0"
     android:pivotX="100%"
     android:pivotY="10%"
     android:duration="200" />

 @anim/fade_out

 <!-- 左上角缩小 -->
 <scale   xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/accelerate_decelerate_interpolator"
     android:fromXScale="1.0"

     android:pivotX="100%"
     android:pivotY="10%"
     android:duration="200" />

接下来就是使用了

  LostPopupWindow popWindow = new LostPopupWindow(ZiXunDetailActivity.this);
                 ((ImageView)(popWindow.getConentView().findViewById(R.id.img5))).setImageResource(R.drawable.ckplico);
                 ((ImageView)(popWindow.getConentView().findViewById(R.id.img6))).setImageResource(R.drawable.fbplico);
                 ((ImageView)(popWindow.getConentView().findViewById(R.id.img7))).setImageResource(R.drawable.zfplico);
                 ((TextView)(popWindow.getConentView().findViewById(R.id.item_content))).setText("查看评论");
                 ((TextView)(popWindow.getConentView().findViewById(R.id.item_content1))).setText("发表评论");
                 ((TextView)(popWindow.getConentView().findViewById(R.id.item_content2))).setText("转发文章");
                 popWindow.showPopupWindow(linMain);
                 popWindow.onLost(new Lost() {
                     @Override
                     public void onLost(int index) {
                         switch (index){
                             case 0: //转发文章
                                 break;
                             case 1:      //发表评论
                                 lineFooter.setVisibility(View.VISIBLE);
                                 break;
                             case 2://查看评论
                                 Bundle bundle=new Bundle();
                                 bundle.putString("id",mID);
                                 startActivity(PingLunActivity.class, "热门评论", bundle);
                                 break;
                         }
                     }
                 });
