我正在编写一个应用程序,需要从我的数据库中获取一些json,我收到数据,但现在我还试图查看列表视图中显示的信息旁边的图标.

制造麻烦的路线是:

mChart.setTag(URL);
new DownloadImagesTask.execute(mChart); <------

主要活动:

public class MainActivity extends Activity {

  ListView list;
  TextView icon;
  TextView name;
  TextView developer;
  TextView size;

  Button Btngetdata;

  ArrayList<HashMap<String, String>> mList = new ArrayList<HashMap<String, String>>();

  private static String url = "http://appwhittle.com/getdata.php";

  private static final String TAG_ITEM = "app_item";
  private static final String TAG_ICON = "app_icon";
  private static final String TAG_NAME = "app_name";
  private static final String TAG_DEVELOPER = "app_developer";
  private static final String TAG_SIZE = "app_size";

  JSONArray mJsonArray = null;

    @Override
    protected void …

我正在构建一个应用程序,我真的想使用ABS(操作栏sherlock)4.0左侧对齐按钮我真的很喜欢Dropbox界面,如下所示:

所以,我的问题是:如何将按钮对齐到左侧,如何使用按钮在ViewFlow中的视图之间跳转？

我已经看到人们可以为他们的ABS添加标签,但不会像Dropbox界面那样添加标题.

谢谢.此外,如果你需要我的源代码,我会在以后需要时添加它.

问候
