I'm trying to use doInBackground method of AsyncTask to send a message to a webserver. Then use the onPreExecute() and onPostExecute(String result) methods of AsyncTask to change a text control from sending data to Fineshed.
The issue is that Inside the AsyncTask String class I cannot access any of the variables declared in the outside class. Thus I cannot change my TextView inside these methods. I get, so mSEnd.setText("Sending data")gives me mSend undefined.
Is there a way to use the variables I declare in my outside class?
public class EndOfWorldActivity extends cBase implements OnClickListener {
TextView textCountDown;
TextView textPercent;
public void onClick(View v) {
Intent i;
switch(v.getId())
{
case R.id.butVote3:
// Start ASync Task
new SendTextOperation().execute("");
break;
case R.id.buGame:
// Start ASync Task
new SendTextOperation().execute("");
break;
}
}
private class SendTextOperation extends AsyncTask<String, Void, String> {
@Override
protected void onPreExecute() {
//Update UI here
mSEnd undefined error
mSend.setText("Sending your vote to server");
mSend.invalidate();
}
@Override
protected String doInBackground(String... params) {
// Talk to server here to avoid Ui hanging
// talk to server method undefined
TalkToServer( mYes[mPes-1] );
return null;
}
@Override
protected void onPostExecute(String result) {
// Update screen here after talk to server end
UpdateScreen();
mSend .setText("");
}
}
} // end of class
