Issue
I take the names and phone numbers of people with string with background thread and use them somewhere. Everything works, but I want to do something. I want to show users something when this thread runs out. But I don't know how to check the condition of this thread. I'd appreciate it if you helped. Thanks in advance.
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,null,null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
AsyncTask.execute(new Runnable() {
@Override
public void run() {
while (cursor.moveToNext()){
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).trim();
}
cursor.close();
}
});
}
Solution
You can do it like this :
public class Processing extends AsyncTask<Void, Void, Void>
ProgressDialog mProgress;
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgress = new ProgressDialog(YOUR_ACTIVITIY.this);
mProgress.setTitle("Processing");
mProgress.setMessage("Please wait ...");
mProgress.show();
@Override
protected Void doInBackground(Void... voids) {
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,null,null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
AsyncTask.execute(new Runnable() {
@Override
public void run() {
while (cursor.moveToNext()){
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).trim();
}
cursor.close();
}
});
}
}
@Override
protected void onPostExecute(Void v) {
super.onPostExecute(v);
mProgress.dismiss();
}
}
