57、android 应用内全局通知的实现方法

 1         ViewGroup decor = (ViewGroup) mWindow.getDecorView();//获取根布局
 2         ViewGroup above = (ViewGroup) decor.getChildAt(0);//获取activity的布局
 3         decor.removeView(above);
 4         above.setBackgroundDrawable(decor.getBackground());
 5 　　　　　/**自定义通知开始**/
 6         LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 7 
 8         RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
 9         rlNotifactions.setLayoutParams(lp);
10 
11         View grid = inflater.inflate(R.layout.listview_notification,null);
12         ListView listview = (ListView)grid.findViewById(R.id.listview_notification_list);
13         listview.setAdapter(adapter);
14         RelativeLayout.LayoutParams lpTv = new RelativeLayout.LayoutParams(790, ViewGroup.LayoutParams.MATCH_PARENT);
15         lpTv.addRule(RelativeLayout.ALIGN_PARENT_TOP|RelativeLayout.ALIGN_PARENT_RIGHT);
16         lpTv.setMargins(0, 100, 0, 0);
　　　　　　/**自定义通知结束**/
17         rlNotifactions.addView(grid,lpTv);
18 
19         mAboveView.addView(above);

22         addView(mAboveView);
23         addView(rlNotifactions);
24         decor.addView(this);//this指的是上文提到的自定义frameLayout
25     }
