Listview gridview TV 焦点落在item上面修改背景色

直接上代码：

ListView list = (ListView) findViewById(R.id.thunk_list);final ThunkAdapter thunkAdapter = new ThunkAdapter(this, getData());list.setAdapter(thunkAdapter);list.setItemsCanFocus(true);//这句话起作用

背景色：

<ListView    android:id="@+id/scene_list"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:layout_alignParentStart="true"    android:divider="@android:color/transparent"    android:scrollbars="none"    android:listSelector="@drawable/bg_button_focused" />

关键：android:listSelector="@drawable/bg_focused"
