运行机器人电气Junit测试时，我得到由
引起的StackOverFlow错误ProgressDialog.show ()
AsyncTask内部的调用。
我有以下活动:
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();
}
}
}
}
后面是堆栈跟踪:

tryfinal ProgressDialog dialog = new ProgressDialog(getApplicationContext);
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();
}
我想会有用的。看看吧，告诉我。
