Question

Lorsque je clique sur la vue vidéo, j'ouvre une autre activité et je joue la vidéo en mode plein écran. Lorsque je suis appuyé sur l'activité ne peut pas passer à l'activité précédente qui contient listview.

quand je pressais bouton retour les mêmes charges d'activité, il ne va pas à activité précédente

Même i essayer

finish() 
moveTaskToBack(true); 

Mais pas d'utilisation ....

ListviewActivity

Intent intent = new Intent(MainActivity.this, VideoActivity.class); 
intent.putExtra("VideoURL", MY_VIDEO_URL); 
startActivity(intent); 

VideoActivity

public class VideoActivity extends Activity { 

VideoView videoSurface; 
ProgressDialog pDialog; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.video_activity); 

    ToastMsg.displayShortToastMsg("CREATE"); 
    String videoUrl = getIntent().getStringExtra("VideoURL"); 

    pDialog = new ProgressDialog(VideoActivity.this); 
    pDialog.setMessage("Loading Please Wait..."); 
    pDialog.setIndeterminate(false); 
    pDialog.setCancelable(false); 
    pDialog.show(); 

    videoSurface = (VideoView) findViewById(R.id.videoSurface); 

    try { 
     // Start the MediaController 
     MediaController mediacontroller = new MediaController(
       VideoActivity.this); 
     mediacontroller.setAnchorView(videoSurface); 
     // Get the URL from String VideoURL 
     Uri video = Uri.parse(videoUrl); 
     videoSurface.setMediaController(mediacontroller); 
     videoSurface.setVideoURI(video); 

    } catch (Exception e) { 
     Log.e("Error", e.getMessage()); 
     e.printStackTrace(); 
    } 

    videoSurface.requestFocus(); 
    videoSurface.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
     // Close the progress bar and play the video 
     public void onPrepared(MediaPlayer mp) { 
      pDialog.dismiss(); 
      videoSurface.start(); 
     } 
    });

Answer 1

Essayez avec l'ajout de ce qui suit dans manifeste.

<activity 
    android:name=". VideoActivity" 
    android:parentActivityName=".MainActivity"> 
    <meta-data 
    android:name="android.support.PARENT_ACTIVITY" 
    android:value=".MainActivity"/> 
</activity> 

Answer 2

Essayez ceci: -

videoSurface.setMediaController(new MediaController(this){ 
    public boolean dispatchKeyEvent(KeyEvent event){ 

     if (event.getKeyCode() == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) 
      finish(); 
     return super.dispatchKeyEvent(event); 
    } 
}); 

Answer 3

S'il vous plaît vérifier si vous avez ajouté des méta-données

<activity 
     android:name=".VideoActivity"> 
     <meta-data 
      android:name="android.support.PARENT_ACTIVITY" 
      android:value="YOUR_PAKAGE_NAME.VideoListActivity" /> 
    </activity> 

pour votre VideoActivity dans le fichier Manifest.

Answer 4

VideoView peut consume l'événement ACTION_DOWN, et ainsi KEYCODE_BACK ne se déclenche jamais dans le dispatchKeyEvent().

De Context

utiliser ce code dans votre activité:

videoSurface.setMediaController(new MediaController(this){ 
    public boolean dispatchKeyEvent(KeyEvent event) 
    { 
     if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) 
      ((Activity) getContext()).finish(); //finish current activity 

     return super.dispatchKeyEvent(event); 
    } 
});
