如何在android中显示进度控制或gif？

当我点击按钮调用webservice时，它会等待加载新活动的记录，并在这段时间内将活动显示为空白

有谁能指导我如何在这段时间内显示进度吗？

您可以显示活动的进度视图：

public class MyActivity extends Activity {
     private static final int PROGRESS = 0x1;

     private ProgressBar mProgress;

     private Handler mHandler = new Handler();

     protected void onCreate(Bundle icicle) {
         super.onCreate(icicle);

         setContentView(R.layout.progressbar_activity);

         mProgress = (ProgressBar) findViewById(R.id.progress_bar);
         mProgress.setIndeterminate(true);
         mProgress.setVisibility(true);

         // Start lengthy operation in a background thread
         new Thread(new Runnable() {
             public void run() {
                 doWork();
                 mProgress.setVisibility(false);
             }
         }).start();
     }
 }
