布局示意：

代码部分：

/*
 * 在当前页面调用initPopUpWindow方法，底部弹出popUpWindow
 * 重点在popUpWindow的layout最外层布局设置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 ，底部弹出框的View
  final View popView = LayoutInflater.from(mContext).inflate(
    R.layout.layout_bottom_popwindow, null);
  View rootView = root; // 当前页面的根布局
  //创建popUpWindow对象 宽高占满页面
  final PopupWindow popupWindow = new PopupWindow(popView,
    WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
  popupWindow.setTouchable(true);
  // 设置弹出动画
  popupWindow.setAnimationStyle(R.style.anim_edit_text_popup);
  // 显示在根布局的底部
  popupWindow.showAtLocation(rootView, Gravity.BOTTOM | Gravity.LEFT, 0,
    0);
  //点击底部弹出框之外的部分让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;
   }
  });
  //弹出框中控件的点击事件
  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>
   }  }); }

进入时从最下方弹出到最上方

消失时从最上方向下移动直到隐藏

<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:
