无法显示进度对话框

Question

我正在使用ProgressDialog在我的android app中显示loading页面。

我的代码如下所示：

final ProgressDialog dialog = new ProgressDialog(this); 
      dialog.setCancelable(false); 
      dialog.setMessage("please Wait ..."); 
      dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
      dialog.setProgressStyle(R.style.progress_dialog_style); 
      dialog.show(); 
      String toastMsg = null; 
      LoginService loginService = new LoginService(LoginActivity.this); 
      ProfileDetails profileDetails = loginService.checkLogin(mobile_number.getText().toString().trim(), password.getText().toString().trim()); 
      if(profileDetails != null && loginService.changeLogin(MainActivity.LOGIN_YES, mobile_number.getText().toString().trim())) { 
       toastMsg = MainActivity.LOGIN_SUCCESSFUL; 
      } 
    if(profileDetails == null) { 
    runOnUiThread(new Runnable() { 
      public void run() { 
       dialog.dismiss(); 
      } 
     }); 
    } 

，然后我进行一些DB Operations，并得到一些数据

我用dialog.dismiss()。

，如果我得到的数据成功地我使用startActivity(intent);

这里

i)如果我使用dialog.dismiss()当我跑我不能够看到对话框的代码。

ii)当我删除dialog.dimiss()部分我能够看到对话框但无法关闭它。

请解决此问题。

谢谢

Answer 1

runOnUiThread(new Runnable() { 
    @Override 
    public void run() 
    { 
    progress.dismiss(); 
    } 

解散你在运行的线程对话是这样的。
