将ProgressDialog添加为异步任务会降低性能

Question

这是我的登录代码。

public void Login_Click(View view) {
HashMap<String, String> op_Config = XMLParser
        .parse(LoginActivity.this);
}

完成执行大约需要4秒。所以我添加了这样的进度对话框。

public void Login_Click(View view) {
 new IsLogedIn().execute();
}

class IsLogedIn extends AsyncTask<String, String, String> 
{   
@Override
protected void onPreExecute() {
    super.onPreExecute();
    showDialog(progress_bar_type);
}   
@Override
protected String doInBackground(String... value) {
    try
    {   
        HashMap<String,String> op_Config = XMLParser.parse(LoginActivity.this);
        finish();
        Intent intent=new Intent(LoginActivity.this,MainMenuActivity.class);
        startActivity(intent);  
    }
    catch (Exception e) {
    }               
}
@Override
protected void onPostExecute(String file_url) {
    dismissDialog(progress_bar_type);       
}
}

但现在完成时间超过1分钟。

尝试这样做

  class IsLogedIn extends AsyncTask<String, String, String> 
    {   
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        showDialog(progress_bar_type);
    }   
    @Override
    protected String doInBackground(String... value) {
        try
        {   
            HashMap<String,String> op_Config = XMLParser.parse(LoginActivity.this);      
        }
        catch (Exception e) {
        }               
    }
    @Override
    protected void onPostExecute(String file_url) {

    if(dilog.isShowing()){
      dismissDialog(progress_bar_type); 
      }

     finish();
     startActivity(new Intent(LoginActivity.this,MainMenuActivity.class));    

    }
    }
