Question

我正在使用系统覆盖图来显示用户需要在应用程序范围内向某个问题发出警报的通知图标。当活动被破坏时，我会看到一个泄漏的窗口，但我正在移除视图。

代码位于基本活动中，该活动由应用程序中的大多数其他活动扩展。

protected void createOverlay(){
    if (overlayCreated) return;

    // Create System overlay video
    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.FILL_PARENT, 150,
            WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                    | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.BOTTOM;

    LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
    mOverlay = (LinearLayout) inflater.inflate(R.layout.overlay_notification, null);
    mOverlayImageView = (ImageView) mOverlay.findViewById(R.id.overlay_notification_image);

    WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    wm.addView(mOverlay, params);

    final Context context = this;

    mOverlay.setOnTouchListener(new View.OnTouchListener(){
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(context, "WootHa!", Toast.LENGTH_SHORT).show();
            return true;
        }
    });
}

破坏

@Override
public void onDestroy() {
    super.onDestroy();

    // Remove view from WindowManager
    if (mOverlay != null) {
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        wm.removeView(mOverlay);

        mOverlay = null;
        mOverlayImageView = null;
    }
}

错误：

我有同样的问题。就我而言，我使用了wm.removeViewImmediate（View）而不是removeView（View）来解决我的问题。也许你可以尝试一下。
