android - AsyncTask OnPostExecute not updating TextView

Question

I have an AsyncTask running. I have a TextView that I mimic the message a Toast initially produces. I want to clear the TextView upon success in OnPostExecute but it not doing so. The task complete Toast works fine. How do I set the TextView in the OnPostExecute to blank? The user is still on the display screen where the TextView is.

Code is as follows for an error condition:

@Override
protected void onPostExecute(Void result) 
 { FetchingImage=0;
  if(webLoadError>0)
   {
    TextView text = (TextView) findViewById(R.id.textView2);
    String temp=" ";
    text.setText(temp);
    Toast.makeText(getApplicationContext(), "Image not available from the internet.
Default or last image loaded.
Try again later.",Toast.LENGTH_LONG).show();
    }  
  }

Answer 1

Try something like:

((TextView) findViewById(R.id.textView2)).setText("");

EDIT:

try making a variable outside the onCreate like TextView text; and then inside the onCreate put: text = (TextView) findViewById(R.id.textView2);

and then just put text.setText(""); inside the onPostExecute method.

See if that works.
