從VideoView中的暫停狀態播放視頻

Question

對於自定義視頻，我必須重寫MediaController（更改按鈕的設計並連接到按鈕暫停/播放選擇器）。情況是這樣的：將視頻暫停並轉動應用程序，然後再次恢復，視頻開始再次播放，而不是從暫停的位置開始播放，因此問題出現了：如何使視頻開始播放從哪裏停下來？ VideoActivity中需要更改哪些內容？

public class VideoActivity extends Activity { 

VideoView videoView; 

VkMediaController mc; 

private static final String CURRENT = "duration"; 

private static final String URL = "url"; 

private Uri mURI; 

private int mCurrentPosition = -1; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.setContentView(R.layout.video_view_player); 
    videoView = (VideoView) findViewById(R.id.videoViewplayer); 
    mc = new VkMediaController(this); 
    mURI = getIntent().getData(); 
    if (savedInstanceState != null) { 
     mURI = Uri.parse(savedInstanceState.getString(URL)); 
     mCurrentPosition = savedInstanceState.getInt(CURRENT); 

    } 
    videoView.setMediaController(mc); 
    videoView.setVideoURI(mURI); 
    videoView.requestFocus(); 
} 

@Override 
protected void onStart() { 
    super.onStart(); 
    videoView.start(); 
    if (mCurrentPosition != -1) { 
     videoView.seekTo(mCurrentPosition); 
    } 
} 

@Override 
public void onSaveInstanceState(Bundle outState) { 
    outState.putInt(CURRENT, videoView.getCurrentPosition()); 
    outState.putString(URL, mURI.toString()); 
    super.onSaveInstanceState(outState); 
} 

}

Answer 1

我認爲這個問題是videoView.getCurrentPosition()總是返回0，當你調用內部onSaveInstanceState(Bundle outState)，COS當時的視頻已經復位，所以叫videoView.getCurrentPosition()時onPause()，這將返回你所期望的值。

Answer 2

我有同樣的問題。我以爲我做了一切正確，但它沒有奏效。然後我只是改變了順序，所以我第一次打電話VideoView.seekTo()，然後VideoView.start()。這工作。 我也有VideoView.requestFocus()在那裏，但我不知道這是否重要。

videoPlayer.requestFocus(); 
videoPlayer.seekTo(position); 
videoPlayer.start(); 

所以，如果你確定你的位置變量有正確的值，這可能是你的答案。 視頻未加載時，您可能無法查找。像這樣實現onPreparedListener：

public class VideoActivity extends Activity implements OnPreparedListener { 
    VideoView videoPlayer; 
    int position; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    if(savedInstanceState!=null){ 
    position=savedInstanceState.getInt("pos") 
    } 
    // setting up the videoview 
    setContentView(R.layout.activity_video); 
    getIntent().getExtras().getString("url"); 
    Uri videouri = Uri.parse(getIntent().getExtras().getString("url")); 
    videoPlayer = (VideoView) findViewById(R.id.videoView); 
    videoPlayer.setOnPreparedListener(this); 
    videoPlayer.setKeepScreenOn(true); 
    videoPlayer.setVideoURI(videouri); 

    } 

    /** 
    * Start the plaback when the video is loaded 
    * 
    * @param mp 
    * @see android.media.MediaPlayer.OnPreparedListener#onPrepared(android.media.MediaPlayer) 
    */ 
    public void onPrepared(MediaPlayer mp) { 
    //this is a TextView infront of the VideoView which tells the User the Video is loading- hide that 
    findViewById(R.id.tv_video_load).setVisibility(View.GONE); 

    videoPlayer.requestFocus(); 
    videoPlayer.seekTo(position) 
    videoPlayer.start(); 
} 
}
