java - MediaController/VideoView 导致 android.view.WindowLeaked

Question

我有以下使用 VideoView 和 MediaController 的代码:

    FrameLayout frameLayout = findViewById(R.id.frameLayout);
    VideoView videoView = findViewById(R.id.videoView);
    mediaController = new MediaController(this) {
        @Override
        public void hide() {
            // do not hide
        }

        public boolean dispatchKeyEvent(KeyEvent event) {
            if (event.getKeyCode() == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) {
                ((Activity) getContext()).finish();
            }

            return super.dispatchKeyEvent(event);
        }
    };
    mediaController.setAnchorView(frameLayout);
    videoView.setMediaController(mediaController);
    videoView.setVideoPath("android.resource://" + getPackageName() + "/" + R.raw.meditation);

    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {
            mediaController.show(0);
        }
    }, 100);

问题是当 Activity 结束时，我在日志中收到以下错误:

10-28 05:57:16.075 6535-6535/com.kjdion.anxietynow E/WindowManager: android.view.WindowLeaked: Activity com.kjdion.anxietynow.MeditationActivity has leaked window DecorView@13fd277[] that was originally added here at android.view.ViewRootImpl.(ViewRootImpl.java:485) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:346) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:93) at android.widget.MediaController.show(MediaController.java:364) at com.kjdion.anxietynow.MeditationActivity$2.run(MeditationActivity.java:53) at android.os.Handler.handleCallback(Handler.java:790) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:164) at android.app.ActivityThread.main(ActivityThread.java:6494) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:438) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)

尽管出现此错误，但一切正常。

为什么会发生这种情况，我该如何解决？

Answer 1

这是因为您覆盖了 Controller 的隐藏方法，因此它不会隐藏。如果可以，请将其删除，代码应该可以正常工作。
