Do I still have to pass the ActivityContext to the AsyncTask in order to manipulate Views?

Question

This function runs on the UiThread, but it seems that doesnt mean it also has access to the activity context. Shall I implement to my AsyncTask a public Setter to pass the activity (as reference)?

protected void onPostExecute( Bitmap bitmap ) {
         //following is underlined red due to missing context
        (ImageView)findViewById(ResId)).setImageBitmap(bitmap); 
      }

Answer 1

I can think about two options.

1. If the AsyncTask is an inner class of you activity you can use getApplicationContext() to get the Context object, without passing the activity object.
2. If you have to access the ImageView object from different methods or if the task handled by the AsyncTask class can run multiple times you might think about storing the ImageView object as a member of your activity class, so you can don't need a context to access it.
