Question

public void accessMetaData(int songIndex) 
{ 
    MediaMetadataRetriever retriver = new MediaMetadataRetriever(); 


    retriver.setDataSource(songsList.get(songIndex).get("songPath")); 

    showMetaData(retriver); 
} 

public void showMetaData(MediaMetadataRetriever retriver) 
{ 
    // Log.i("Script", "METADATA_KEY_ALBUM: " +retriver.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUM)); 
    // Log.i("Script", "METADATA_KEY_ALBUMARTIST: " +retriver.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUMARTIST)); 


    byte [] imgBytes = retriver.getEmbeddedPicture(); 
    Bitmap bitmap ; 

    if(imgBytes != null) { 

     bitmap = BitmapFactory.decodeByteArray(imgBytes, 0, imgBytes.length); 

    ImageView ivImage = (ImageView)findViewById(R.id.ivImage); 
     ivImage.setImageBitmap(bitmap); 

    /* PlayListActivity.ay7aga = (ImageView)findViewById(R.id.widget_album_art); 
     ivImage.setImageBitmap(bitmap); */

j'ai ce code pour obtenir l'art de l'album dans l'activité A ,, je veux passer même album art à l'activité B et ce code obtenir l'art de l'album pour la chanson de lecture en cours

Answer 1

si je suis votre question que vous pouvez passer l'image d'une activité à l'autre. Convertissez votre album d'images ImageView en bitmap. Définissez la propriété DrawingCache de votre ImageView sur true, puis enregistrez l'arrière-plan en tant que bitmap et transmettez-le via putExtra.

image.setDrawingCacheEnabled(true); 
    Bitmap b=image.getDrawingCache(); 
    Intent i = new Intent(this, nextActivity.class); 

    i.putExtra("Bitmap", b); 
    startActivity(i); 

Et dans votre activité suivante,

Bitmap bitmap = (Bitmap) intent.getParcelableExtra("Bitmap"); 
imageView.setImageBitmap(bitmap); 

Answer 2

btnPlaylist.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 

     /* Intent i = new Intent(getApplicationContext(), PlayListActivity.class); 
      Bitmap bmOriginal = BitmapFactory.decodeResource(getResources(), R.id.ivImage); 
      i.putExtra("ha",bmOriginal); 
      startActivityForResult(i, 100); */ 

      Intent i = new Intent(getApplicationContext(), PlayListActivity.class); 
      ivImage.buildDrawingCache(); 
      Bitmap bitmap = ivImage.getDrawingCache(); 

      i.putExtra("BitmapImage", bitmap); 



     } 
    }); 

}
