我试图等到启动 AsyncTask 将从服务器获得结果，以便主要活动将继续，在我的启动屏幕上，我有一些带有加载过程栏的 GUI，等等。

但是当我运行它时，我会强制关闭。这是我的主要活动代码：

 lv.setOnItemClickListener(new OnItemClickListener() 
 {
     public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
     new Thread() { public void run() 
     {
         runOnUiThread(new Runnable() {
             public void run() {
                 splash  splash=(tools.splash) new splash(first.this).execute();
                 int waited = 0;
                 while(splash.running && (waited< getResources().getInteger(R.integer.splashTimeOut)))
                 {
                     try {
                         wait(100);
                         } catch (InterruptedException e) {
                             // TODO Auto-generated catch block
                             e.printStackTrace();
                         }
                         if(splash.running) {
                             waited += 100;
                         }
                         // nextActivity=splash.newActivity;
                     }
                     Intent intent = null;
                     try {
                         intent = new Intent(first.this,Class.forName("activities.third"));
                     } catch (ClassNotFoundException e) {
                         // TODD Auto-generated catch block
                         e.printStackTrace();
                     }
                     startActivity(intent);
                 }

              });
          }
      }.start();

我认为它需要等待。希望你能帮忙。

您需要与您正在调用的对象同步wait()。在这种情况下，你应该可以说

synchronized(this){
    wait(100);
}

runOnUiThread在 UI 线程上运行。您无权通过调用连续等待（100）来阻止它；

此外，您的代码中没有 Asynctask ......
