如何使用「Android通用圖像加載程序」

Question

我想要使用Android通用圖像加載程序的gridview和listview。

https://github.com/nostra13/Android-Universal-Image-Loader

我下載並修改它。

它工作正常，但是當我更改並移動源到另一個項目時，它崩潰了。

我不知道爲什麼:(

沒有錯誤和任何錯誤消息。

我認爲這是零點錯誤或啓動庫。

我認爲錯誤將帶有此一部分。

listView = (GridView) findViewById(R.id.gridview); 
    ((GridView) listView).setAdapter(new ImageAdapter()); 

和

public class ImageAdapter extends BaseAdapter { 
    @Override 
    public int getCount() { 
     Log.v("OWL","TEST1"); 
     return imageUrls.length; 
    } 

    @Override 
    public Object getItem(int position) { 
     Log.v("OWL","TEST2"); 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     Log.v("OWL","TEST3"); 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     Log.v("OWL","TEST4"); 
     final ImageView imageView; 
     if (convertView == null) { 
      imageView = (ImageView) getLayoutInflater().inflate(R.layout.item_grid_image, parent, false); 
      Log.v("OWL","TEST5"); 
     } else { 
      imageView = (ImageView) convertView; 
      Log.v("OWL","TEST6"); 
     } 

     imageLoader.displayImage(imageUrls[position], imageView, options); 
     Log.v("OWL","TEST7"); 
     return imageView; 
    } 
} 

我無法看到LOGCAT上的TEST6，TEST7

我附上了日誌打擊。請幫助我或讓我知道如何使用該庫。

Answer 1

的你解決這個問題呢？你需要初始化的UniversalImageLoader示例代碼的ImageLoader的：

File cacheDir = StorageUtils.getCacheDirectory(context); 
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) 
     .memoryCacheExtraOptions(480, 800) // default = device screen dimensions 
     .discCacheExtraOptions(480, 800, CompressFormat.JPEG, 75) 
     .taskExecutor(AsyncTask.THREAD_POOL_EXECUTOR) 
     .taskExecutorForCachedImages(AsyncTask.THREAD_POOL_EXECUTOR) 
     .threadPoolSize(3) // default 
     .threadPriority(Thread.NORM_PRIORITY - 1) // default 
     .tasksProcessingOrder(QueueProcessingType.FIFO) // default 
     .denyCacheImageMultipleSizesInMemory() 
     .memoryCache(new UsingFreqLimitedMemoryCache(2 * 1024 * 1024)) // default 
     .memoryCacheSize(2 * 1024 * 1024) 
     .discCache(new UnlimitedDiscCache(cacheDir)) // default 
     .discCacheSize(50 * 1024 * 1024) 
     .discCacheFileCount(100) 
     .discCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default 
     .imageDownloader(new BaseImageDownloader(context)) // default 
     .defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // default 
     .enableLogging() 
     .build(); 

Answer 2

看起來無論你創建你imageLoader，你需要調用imageLoader.init(someConfigObject);

someConfigObject的類型是ImageLoaderConfiguration

Answer 3

使用這個簡單的代碼工作

初始化ImageLoader的成侑適配器類

imageLoader = ImageLoader.getInstance(); 
imageLoader.init(ImageLoaderConfiguration.createDefault(ctx)); 

然後使用下面的代碼到放置在設置圖像它將工作...

DisplayImageOptions options=new DisplayImageOptions.Builder() 
       .cacheInMemory(true) 
       .resetViewBeforeLoading(true) 
       .showImageOnFail(R.drawable.stories_holder_sq) 
       .showImageForEmptyUri(R.drawable.stories_holder_sq) 
       .showImageOnLoading(R.drawable.stories_holder_sq) 
       .build(); 
     imageLoader.displayImage(naturalDashBoardBean.getImgUrl(), categoryViewHolder.categoryItemImg, options);
