Question

我的应用使用：

WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

我通过代码将视图添加到windowManager：

MyContextWrapper myContextWrapper= new MyContextWrapper(this);
// I created customview in myContextWrapper
View view = myContextWrapper.getView();

int FLAG = WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED 
                    | WindowManager.LayoutParams.FLAG_FULLSCREEN
                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION 
                    | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH 
                    | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD;
int type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
WindowManager.LayoutParams params = new WindowManager.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, type,
                FLAG, PixelFormat.UNKNOWN);
mWindowManager.addView(view, params);

删除视图后，如何清除视图内存？我想清除它，因为在新的MyContextWrapper（this）getview之后内存增加并添加到mWindowManager。

 mWindowManager.removeView(view);

myContextWrapper.getView（）include（ImageView，ViewPager ...）

从WindowManager中删除视图时如何清除内存
