Android - Imageloader muss mit Konfiguration init werden, bevor in UIL mit

Question

habe ich den Fehler:

ImageLoader must be init with configuration before using is the error from Illegal State Exception.

ich kämpfen, um die Bilder in meinem Ansatz zur Anzeige der Gridview innerhalb eines Bruchstücke setzen. Was mein Verständnis betrifft, sollte die imageLoader zuerst initialisiert werden, indem die Klasse AbsListViewBaseActivity erweitert wird, die BaseActivity erweitert wird.

Diese beiden Klassen werden verwendet, um die imageLoader zu initialisieren. Ich habe den Fluss ziemlich durcheinander gebracht, und ich bekomme Fehler in der Laufzeit und arbeite damit in zwei Tagen. Ich werde LogCat-Fehler einbeziehen.

Stationierungs von diesem Ansatz:

ImageGallery

Answer 1

Versuchen Sie dies in Ihrem onCreateView implementieren:

BaseActivity.imageLoader.init(ImageLoaderConfiguration.createDefault(getBaseCont‌​ext())); 

Answer 2

Ich glaube, Sie den Universal-Image Loader API verwenden. Wenn ja, haben Sie vergessen, den Image Loader in der Application-Klasse zu konfigurieren.

die unten Funktion in der Anwendungsklasse:

public static void initImageLoader(Context context) { 

    // This configuration tuning is custom. You can tune every option, you may tune some of them, 
    // or you can create default configuration by the 
    // ImageLoaderConfiguration.createDefault(this); 
    // method. 
    // 
    ImageLoaderConfiguration.Builder config = new ImageLoaderConfiguration.Builder(context); 
    config.threadPriority(Thread.NORM_PRIORITY - 2); 
    config.denyCacheImageMultipleSizesInMemory(); 
    config.diskCacheFileNameGenerator(new Md5FileNameGenerator()); 
    config.diskCacheSize(50 * 1024 * 1024); // 50 MiB 
    config.tasksProcessingOrder(QueueProcessingType.LIFO); 
    config.writeDebugLogs(); // Remove for release app 

    // Initialize ImageLoader with configuration. 
    ImageLoader.getInstance().init(config.build()); 
} 

Für weitere Informationen, lesen Sie this sample.

Answer 3

Prüfen Sie zunächst, dass Benutzer imageLoader.jar Paket ordnungsgemäß in das Projekt einbezogen wird in Projekteigenschaften → Java Build-Pfad gehen.

Zweitens implementieren Sie diesen Code in der onCreateView: BaseActivity.imageLoader.init (ImageLoaderConfiguration.createDefault (getBaseCont ext()));

Answer 4

Einfach den folgenden Code in der BaseActivity oder MyApplication Klasse:

public ImageLoader getImageLoader() { 

    if (mImageLoader == null) { 
     mImageLoader = ImageLoader.getInstance(); 
     mImageLoader.init(ImageLoaderConfiguration.createDefault(this)); 
    } 
    return this.mImageLoader; 
} 

Dann, wenn Sie das Bild Loader verwenden wollen, dann eine neue Instanz von Imageloader erstellen, genau wie die folgenden:

private ImageLoader imageLoader = MyApplication.getInstance().getImageLoader(); 

Oder wenn Sie nehmen BaseActivitiy Code eingeben hier:

private ImageLoader imageLoader = BaseActivity.getInstance().getImageLoader(); 

Answer 5

Das hat besser für mich funktioniert.

Legen Sie die folgenden in der onCreate Ihrer Tätigkeit

ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(MyActivity.this));
