我在使用RecycleView和WindowManager(TYPE_SYSTEM_ALERT)时有一种奇怪的行为。由于某种原因,ItemList的属性(填充,宽度,高度,......)被忽略。我不知道发生了什么。我想和你们一起检查一下我是不是错过了什么或做错了什么。
在WindowManager上充气列表:
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
paramsMap = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
PixelFormat.OPAQUE);
final RecyclerView recyclerView = new RecyclerView(getApplicationContext());
recyclerView.setAdapter(new CustomListAdapter(list));
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setPadding(0,0,0,0);
wm.addView(recyclerView, paramsMap);
项目布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="90dp"
