Question

我想创建一个应用。从json中的Server获得分数并将其显示在我的应用程序上。但自动刷新不起作用。当它自动刷新时，它显示两个旧值和更新值。

String s1=" ";
String s2=" ";
String s3=" ";
String s4=" ";
String s5=" ",s6=" ",s7=" ",s8=" ",s9=" ",s10=" ",s11=" ",s12=" ",s13=" ";

检查我的评论你在conning循环中运行

private Runnable updateTask = new Runnable () 
{
  public void run() 
 {
    Log.d(getString(R.string.app_name) + " ChatList.updateTask()",
            "updateTask run!");

                // run any code here...
    //getdata();
    new BackHelper().execute();
    Log.e("hell", "hello");
    // queue the task to run again in 15 seconds...
 // here i think your in continues loop. check
    mHandler.postDelayed(updateTask, 15000);
}
 };
