java - 如何关闭膨胀的布局？

Question

我使用 TYPE_SYSTEM_ALERT 和 FLAG_LAYOUT_IN_SCREEN 扩充布局

 params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.FILL_PARENT,
            WindowManager.LayoutParams.FILL_PARENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_ALERT ,
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
            Color.YELLOW);

    wm = (WindowManager) getApplicationContext()
            .getSystemService(Context.WINDOW_SERVICE);

    mTopView = (ViewGroup) getLayoutInflater().inflate(R.layout.lock_screen, null);
    getWindow().setAttributes(params);
    wm.addView(mTopView, params);

如何关闭或关闭它？

Answer 1

需要时使用下面的代码删除 View

if(mTopView!=null) {
   wm.removeView(mTopView);
}
