代碼部分：

/*
 * 在當(dāng)前頁面調(diào)用initPopUpWindow方法，底部彈出popUpWindow
 * 重點(diǎn)在popUpWindow的layout最外層布局設(shè)置android:background="#66fafafa" 半透明
 * */
 private void initPopUpWindow(View root, final String uuid, final String title){
 Log.d("click","init popopop");
 //inflate得到布局 ，底部彈出框的View
 final View popView = LayoutInflater.from(mContext).inflate(
  R.layout.layout_bottom_popwindow, null);
 View rootView = root; // 當(dāng)前頁面的根布局
 //創(chuàng)建popUpWindow對象 寬高占滿頁面
 final PopupWindow popupWindow = new PopupWindow(popView,
  WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
 popupWindow.setTouchable(true);
 // 設(shè)置彈出動畫
 popupWindow.setAnimationStyle(R.style.anim_edit_text_popup);
 // 顯示在根布局的底部
 popupWindow.showAtLocation(rootView, Gravity.BOTTOM | Gravity.LEFT, 0,
  0);
 //點(diǎn)擊底部彈出框之外的部分讓popUpWindow 消失
 popView.setOnTouchListener(new View.OnTouchListener() {
  @Override
  public boolean onTouch(View v, MotionEvent event) {
  int height = popView.findViewById(R.id.ll_popupwindow).getTop();
  int y=(int) event.getY();
  if(event.getAction()==MotionEvent.ACTION_UP){
   if(y<height){
   popupWindow.dismiss();
   }
  }
  return true;
  }
 });
 //彈出框中控件的點(diǎn)擊事件
 TextView share_facebook= (TextView) popView.findViewById(R.id.popwindow_facebook);
 share_facebook.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
  share_facebook(uuid,title);
  popupWindow.dismiss();
  }
 });

 final TextView share_whatsApp= (TextView) popView.findViewById(R.id.popwindow_whatsapp);
 boolean whatsappFound = CheckUtils.isAppInstalled(mContext, "com.whatsapp");
 if (whatsappFound) {
  share_whatsApp.setVisibility(View.VISIBLE);
  share_whatsApp.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
   share_whatsapp(uuid,title);
  }
  });
 }

 TextView report= (TextView) popView.findViewById(R.id.popwindow_report);
 report.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
  Intent intent = new Intent(mContext, ReportActivity.class);

  intent.putExtra("fromch", true);

  intent.putExtra("tid", uuid);
  mContext.startActivity(intent);
  popupWindow.dismiss();<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

 <translate
 android:duration="100"
 android:fromYDelta="0.0"
 android:toYDelta="100%" />

</set>
  } }); }

動畫部分

進(jìn)入時從最下方彈出到最上方

消失時從最上方向下移動直到隱藏

<style name="anim_edit_text_popup">
 <item name="android:windowEnterAnimation">@anim/popup_in</item>
 <item name="android:windowExitAnimation">@anim/popup_out</item>
</style>

popup_in:

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >

 <translate
 android:duration="100"
 android:fromYDelta="100.0%"
 android:toYDelta="0.0" />

</set>

pop_out:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

 <translate
