ボタンのクリックイベントが終了しました。実行中のASyncTaskのアクティビティインスタント

Question

私のアプリケーションに問題があります。ボタンをクリックしてASyncTaskを実行したいが、実行中のタスクがinstedされていると、現在のActivityが閉じられる。私はなぜ、私はそれを修正する方法がわからないのか分からない。誰かが問題を知っていますか？

public class SpeedTestActivity extends BaseActivity { 

    private View mRunningBar; 
    private TextView uploadLabel; 
    private TextView uploading;

Answer 1

コードが

.............your code ....... 

private final View.OnClickListener testButtonClicked = new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      new SpeedTestTask().execute(); 
     } 
    }; 

のようになりますので、実際にリスナーとしてそれを設定する前に testButtonClicked Click Listenerを定義します

この行：

findViewById(R.id.start_test).setOnClickListener(testButtonClicked); 

.................................... 私はこれが
