使用此功能以列表，图库，网格视图的形式集成图像显示

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

但必须将来自服务器的图像一张一张地整合在一起..请建议我..请给我示例。

public class ParsingActivity extends Activity {
ParsingPojo data_pojo;
ArrayList<ParsingPojo> dataArray;
ListView diagnoList;
ImageView dataWithImage;
private EditText editTextInput;
ProgressDialog mdialog;
ProgressDialog progressDialog;
private Handler handler;
private Handler messageHandler;
private ProgressDialog progress;
private Context context;

String resp, url;
protected DisplayImageOptions displayImage;
protected ImageLoader imageLoader = ImageLoader.getInstance();

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.cat);

    dataWithImage = (ImageView) findViewById(R.id.stack);


    displayImage = new DisplayImageOptions.Builder()
    .showImageForEmptyUri(R.drawable.ic_launcher)
    .showStubImage(R.drawable.ic_launcher)
    .cacheInMemory()
        .cacheOnDisc()
        .bitmapConfig(Bitmap.Config.RGB_565)
        .build();
     imageLoader.init(ImageLoaderConfiguration
    .createDefault(ParsingActivity.this));
     new Task().execute();

}




protected void search() {
    // TODO Auto-generated method stub

}

    TextView coverTitle, content, image;

这是您期望的示例。在此示例中，列表视图图像是从服务器 url 加载的（从服务动态）

看看这个。http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/ 希望这对您有所帮助。

编辑 这是你想要的代码。
