Question

注意：已经访问了this链接，但没有帮助。

在运行Robolectric Junit测试时，我收到了由

引起的StackOverFlow错误

ProgressDialog.show（）

在AsyncTask内部进行调用。

我有以下类型的活动：

public abstract class TransactionFragmentActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.transction_layout);             
        SetUpService setup = new SetUpService();
        setup.execute();
    }

    private class SetUpService extends AsyncTask<String, Void, Boolean> {

        private ProgressDialog dialog = new ProgressDialog(TransactionFragmentActivity.this);

        /** progress dialog to show user that the backup is processing. */
        /** application context. */
        @Override
        protected void onPreExecute() {
            SetUpService.this.dialog.setMessage("Please wait");
            SetUpService.this.dialog.setCancelable(false);
            SetUpService.this.dialog.show();
        }

        @Override
        protected Boolean doInBackground(final String... args) {
            // Setting data 
            Log.d(TAG,"doInBackground...");

            fetchData(); //some method doing work
            return true;
        }


        @Override
        protected void onPostExecute(final Boolean success) {
            if (dialog != null && dialog.isShowing()) {
                dialog.dismiss();
            }
        }
    }
}

以下是stacktrace：

Answer 1

尝试final ProgressDialog dialog = new ProgressDialog(getApplicationContext);

Answer 2

private ProgressDialog dialog = new ProgressDialog(getActivity());

protected void onPreExecute() { 
    dialog.setMessage("Please wait");
    dialog.setCancelable(false);
    dialog.show();
}

或

Activity act = (TransactionFragmentActivity) this;

private ProgressDialog dialog = new ProgressDialog(act);

protected void onPreExecute() { 
    dialog.setMessage("Please wait");
    dialog.setCancelable(false);
    dialog.show();
}

认为它会起作用。看看，告诉我。
