Wie funktioniert Glide in remoteViews?

Question

Ich verwende Glide für alle Bilder vom Server geladen, aber ich habe die Fehlersuche versucht, sie auf korrekte Weise zu Benachrichtigungen und RemoteControlClientCompat (das coole Ding mit Sperrbildschirmen) zu setzen. Ich entwickle einen Musik-Player, so dass sich jedes Mal, wenn ein Song geändert wird, das Cover von Benachrichtigungen ändern muss. Ich habe diesen Code und es funktioniert zum ersten Mal (obwohl das Bild von URL geladen wird oder aus Zeichen), aber nicht, wenn es zum zweiten Mal aufgerufen wird. Das Bild ändert sich nicht! CustomNotification wird aufgerufen, wenn ein Song geändert wird. Und RegisterRemoteClient wird bei der Startaktivität aufgerufen.

Wenn dies nicht der richtige Weg ist, sagen Sie bitte wie.

public void CustomNotification() { 
    Log.d(TAG, "Set custom notification"); 

    simpleRemoteView = new RemoteViews(getApplicationContext().getPackageName(), R.layout.notification_custom); 
    expandedRemoteView = new RemoteViews(getApplicationContext().getPackageName(), R.layout.notification_big); 

    mNotification = new NotificationCompat.Builder(getApplicationContext()) 
      .setSmallIcon(R.mipmap.ic_main_logo) 
      .setTicker(mSongTitle + " - " + mSongAuthors) 
      .setContentTitle(mSongTitle).build(); 

    setRemoteListeners(simpleRemoteView); 
    setRemoteListeners(expandedRemoteView); 

    try { 
     //Check if playingSong has a cover url, if not set one from drawable 
     if(!playingSong.has("cover")){ 
      mDummyAlbumArt = BitmapFactory.decodeResource(getResources(),R.drawable.image_song_album); 
      mDummyAlbumArt2 = BitmapFactory.decodeResource(getResources(),R.drawable.image_song_album); 
      mDummyAlbumArt3 = BitmapFactory.decodeResource(getResources(),R.drawable.image_song_album); 
     }else { 
      Glide.with(MainActivity.context) 
        .load(API.imgUrl(playingSong.getString("cover_img"))) 
        .asBitmap() 
        .into(new SimpleTarget<Bitmap>(100, 100) { 
         @Override 
         public void onResourceReady(Bitmap bitmap, GlideAnimation anim) { 
          mDummyAlbumArt = bitmap; 
          mDummyAlbumArt2 = bitmap; 
          mDummyAlbumArt3 = bitmap; 
         } 
        }); 
     } 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

    mNotification.contentView = simpleRemoteView; 
    mNotification.contentView.setTextViewText(R.id.textSongName, mSongTitle); 
    mNotification.contentView.setTextViewText(R.id.textAlbumName, mSongAuthors);

     mNotification.bigContentView.setTextViewText(R.id.textAlbumName, mSongAuthors); 
     mNotification.bigContentView.setImageViewBitmap(R.id.imageViewAlbumArt, mDummyAlbumArt2); 
    } 

    if (mPlayer != null) { 
     if (!mPlayer.isPlaying()) { 
      mNotification.contentView.setImageViewResource(R.id.btnPlayPause, R.mipmap.play); 
      if (currentVersionSupportBigNotification) { 
       mNotification.bigContentView.setImageViewResource(R.id.btnPlayPause, R.mipmap.play);

       mNotification.bigContentView.setImageViewResource(R.id.btnPlayPause, R.mipmap.pause);

     } 
    } 

    mNotification.flags |= Notification.FLAG_ONGOING_EVENT;

     mNotification.priority = Notification.PRIORITY_MAX; 
    } 
    startForeground(NOTIFICATION_ID, mNotification);

       .putBitmap(RemoteControlClientCompat.MetadataEditorCompat.METADATA_KEY_ARTWORK, mDummyAlbumArt3) 
       .apply();

Answer 1

Sie benötigen Verwendung NotificationTarget Klasse setzen Ihre Mitteilung Bild als glide Ziel

NotificationTarget notificationTarget = new NotificationTarget( 
    context, 
    remoteView, 
    R.id.iv_album_art, 
    notification, 
    NOTIFICATION_ID); 

zu setzen und dann dieses Ziel in üblichen gleiten Art und Weise verwenden

Uri uri = ContentUris.withAppendedId(PlayerConstants.sArtworkUri, 
     mediaitem.getAlbumId()); 

    Glide.with(getApplicationContext()) 
    .load(uri) 
    .asBitmap() 
    .into(notificationTarget); 

Es erklärt in Glides Richtlinie hier

Sie könnten auch Albumcover wie änderungsbezo- Sein hier beschrieben animieren: -

Answer 2

für mich Dies funktionierte:

Bitmap bitmap = Glide.with(mContext) 
       .load(YOUR_IMG_URL) 
       .asBitmap() 
       .into(Target.SIZE_ORIGINAL,Target.SIZE_ORIGINAL) 
       .get(); 
     remoteViews.setImageViewBitmap(R.id.widget_list_item_img,bitmap);
