これは私のソース コードです このアクティビティ public class circlelistparsing extends ActivityGroup これは私のアクティビティです このアクティビティは onButton をロードしています 別のクラスのクリック データをロードするためのプログレス バーを設定したい これを実装する方法を教えてください いろいろ試しましたが表示できませんでしたプログレスバー async タスクを使用した後も表示できません。

このコードを試して、

/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);      

    RelativeLayout fv = new RelativeLayout(this);
    ProgressBar pb = new ProgressBar(this);
    fv.setGravity(Gravity.CENTER);
    fv.addView(pb);
    setContentView(fv); 
}

これは私と一緒にうまくいきます..
