问题描述
我尝试在android中异步执行两个函数。所以我需要第一个功能放弃第二个功能。我尝试使用AsyncTask来执行此操作。但是问题是第一个函数不能等到第一个函数完成。
private class DemandeConge extends AsyncTask<Void,Void,Void> {
protected void onPreExecute() {
super.onPreExecute();
Log.i("we are here","**************On pre Exceute......***************");
p=new ProgressDialog(getActivity());
p.setMessage("Please wait...It is downloading");
p.setIndeterminate(false);
p.setCancelable(false);
p.show();
Log.i("we are here","**************On pre Exceute......***************");
}
@Override
protected Void doInBackground(Void... params) {
Log.i("we are here","**************oOn doInBackground...***************");
getSoldeConge();
Log.i("we are here","**************On doInBackground...***************");
return null;
}
@Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
Log.i("we are here","**************onProgressUpdate...***************");
Log.i("we are here","**************onProgressUpdate...***************");
}
/**
* `onPostExecute` is run after `doInBackground`,and it's
* run on the main/ui thread,so you it's safe to update ui
* components from it. (this is the correct way to update ui
* components.)
*/
@Override
protected void onPostExecute(Void param) {
Log.i("we are here","**************onPostExecute...***************");
Log.i("we are here","**************onPostExecute...***************");
Log.i("we are here","add conge()");
p.dismiss();
}
@Override
protected void onCancelled() {
super.onCancelled();
p.dismiss();
Log.i("we are here","**************onCancelled...***************");
}
}
我有两个函数，第一个是getSoldeConge();，它通过翻新来获取一些数据，第二个函数将在第二个Log.i("we are here","add conge()");有鳍时被排除，但是在我的情况下，第二个函数将在第一个函数完成之前运行
