Question

我正在使用AdapterViewFlipper，它显示来自资源的图像但是当我尝试从url加载动态图像时它没有显示任何内容。

//工作呢

holder.flipper_image_view.setImageResource(R.drawable.app_icon_small);

//无法正常工作

imageLoader.loadImage(imageUrl.trim(),
                options, new ImageLoadingListener() {
                    @Override
                    public void onLoadingStarted(String s, View view) {

                    }

                    @Override
                    public void onLoadingFailed(String s, View view, FailReason failReason) {

                    }

                    @Override
                    public void onLoadingComplete(String s, View view, Bitmap bitmap) {
                        holder.flipper_image_view.setImageBitmap(bitmap);
                    }

                    @Override
                    public void onLoadingCancelled(String s, View view) {

                    }
            });

我已经检查过网址上的图像，并且在浏览器中打开它也很容易使用简单的Imageview。请建议。

试试这个，

NetworkImageView networkImageView = (NetworkImageView) findViewById(R.id.thumbImageUrl);
RequestQueue mRequestQueue = Volley.newRequestQueue(this);
ImageLoader imageLoader = new ImageLoader(mRequestQueue, new BitmapLruCache(BitmapLruCache.getDefaultLruCacheSize()));

networkImageView.setImageUrl(IMAGE_URL, imageLoader);

这是BitmapLruCache.java

public class BitmapLruCache extends LruCache<String, Bitmap> implements ImageCache {

    public static int getDefaultLruCacheSize() {
        final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
        final int cacheSize = maxMemory / 8;

        return cacheSize;
    }

    public BitmapLruCache() {
        this(getDefaultLruCacheSize());
    }

    public BitmapLruCache(int sizeInKiloBytes) {
        super(sizeInKiloBytes);
    }

    @Override
    protected int sizeOf(String key, Bitmap value) {
        return value.getRowBytes() * value.getHeight() / 1024;
    }

    @Override
    public Bitmap getBitmap(String url) {
        return get(url);
    }

    @Override
    public void putBitmap(String url, Bitmap bitmap) {
        put(url, bitmap);
    }}

AdapterViewFlipper不显示动态图像
