android - Activity onPause 奇怪的 Action

Question

我的 Activity 中有一个 onPause。奇怪的是，仅在单个 Activity (videoPlayer)中，onPause 就被调用了两次

场景:这种情况发生在我的手机设备上的视频播放器中，但平板电脑上没有。

按电源按钮进入待机状态，调用 onpause 然后调用 onresume 然后再次调用 on pause。然后再次按下电源按钮，并按预期调用恢复。

有没有人遇到过这样的问题，如果有，你是如何解决的。甚至只是让 onPause onResume onpause 然后打开 onResume。

提前致谢。这个出现了两次

    protected void onPause()
{

    Log.i("VideoPlayer", "onPauseCalled");
    super.onPause();
    pauseMedia();
    Log.i("onPause", " save states to be called");
    if(saveAllowed)
        saveStates();
    Log.i("onPause", " save States called");
    view.setVisibility(View.GONE);
    //Log.i("onPause", "visibility GOne");
    removeListeners();
    doCleanUp();


}

    @Override
protected void onResume()
{
    super.onResume();
    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    Log.i("VideoPlayer", "onResumeCalled");

    if(pm.isScreenOn())
    {
        //Initialization
        initializeViewControls();
        handler = new Handler();

        initializeButtons();
        initRecordButtons();
        initVolumeControl();

        //RestoreState
        restoreMediaBoolean();
        restoreMediaState();
        Log.i("After", "restoreState");
        view = (SurfaceView) findViewById(R.id.surfaceView);
        //Log.i("After", "GettingView");
        holder = view.getHolder();
        view.setVisibility(View.VISIBLE);
        holder.addCallback(this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        Log.i("onResume", "view is Visible");
        saveAllowed = true;
    }
    else
        saveAllowed = false;

}

private void saveStates()
{
    if(!isFinishing)
    {
        //Log.i("VideoPlayer", "Called at saveStates()");

        prefs = getSharedPreferences(PREF_SAVE, Context.MODE_PRIVATE);
        if(prefs != null)
        {
            prefEditor = prefs.edit();
        }

        if(prefEditor != null)
        {

            //Save overlay visibiltiy
            if((volumeLayout != null) && (volumeLayout.getVisibility() == View.VISIBLE))
            {
                prefEditor.putBoolean(IS_VOLUME_VISIBLE, true);
                prefEditor.commit();
            }
            else
            {
                prefEditor.putBoolean(IS_VOLUME_VISIBLE, false);
                prefEditor.commit();
            }

            //Save recorder Overlay state
            if((recordLayout != null) && (recordLayout.getVisibility() == View.VISIBLE) )
            {
                prefEditor.putBoolean(IS_RECORDER_VISIBLE, true);
                prefEditor.commit();
            }
            else
            {
                prefEditor.putBoolean(IS_RECORDER_VISIBLE, false);
                prefEditor.commit();
            }
            //Save controller OVerlay State
            if((backButton != null) && (backButton.getVisibility() == View.VISIBLE))
            {

                prefEditor.putBoolean(IS_CONTROLLER_VISIBLE, true);
                prefEditor.commit();
                Log.i("Save States", "Controller saved as visible");
            }
            else
            {
                Log.i("Save States", "Controller saved as Invisible");
                //Log.i("Saving", "Controller Invisible");
                prefEditor.putBoolean(IS_CONTROLLER_VISIBLE, false);
                prefEditor.commit();
            }

            //Save is private Audio Recorded
            prefEditor.putBoolean(IS_PRIVATE_AUDIO_RECORDED, isCustomVoiceRecorded);
            prefEditor.commit();

            //Save are we playing out custom audio
            prefEditor.putBoolean(PLAY_CUSTOM_AUDIO, playCustomAudio);
            prefEditor.commit();

            //Make boolean is restoring
            prefEditor.putBoolean(IS_RESTORING, true);
            prefEditor.commit();

            //Saves Position of Current Video
            if(vidplayer != null)
            {
                prefEditor.putInt(VIDEO_POSITION, videoPausedAt);
                prefEditor.commit();
            }

            //Save Position of Current Audio
            if(audplayer != null)
            {
                prefEditor.putInt(AUDIO_POSITION, audioPausedAt);
                prefEditor.commit();
            }


            prefEditor = null;
            prefs = null;

        }
    }

发生的事情是我保存了一些布局的状态，比如录音机布局，它在退出时暂停，有点像菜单。然后，如果按下电源，它就会关闭，但当它重新打开时，布局消失了，视频正在播放，这是不应该发生的。

是的，我遇到了类似的问题。您使用的是哪种设备(如果我没有记错，我认为这是 NFC 屏幕超时问题)？暂停对我来说不是问题，但我尝试在 onResume 中恢复视频(被调用两次)所以我在 onResume 中使用了以下内容:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
if (pm.isScreenOn()) {
   //now do stuff
}
