Ich versuche, Bilder von einem URL mit Universal Image Loader und zoom mit TouchImageView Mike Ortiz zu implementieren. Wenn Sie jedoch versuchen, das Bild anzuzeigen, wird schwarzer Bildschirm angezeigt. Ich habe überprüft, dass die URLs korrekt sind. Wenn ich dort einen TextView sehe ...Android: nicht angezeigt ImageView mit UIL und TouchImageView
Was mache ich falsch?

// URLS with data
