Question

There is the following code from custom AsyncTask:

    @Override
    public void onPreExecute() {     
        setTitle();
        dialog.show();
    }

    private void setTitle() {
        Activity activity=(Activity)context;
        TextView title=(TextView)activity.findViewById(R.id.textViewToDoListTitle);
        Log.e("title", title.getText().toString());
        title.setText("123");
        Log.e("title", title.getText().toString());
    }

This code works without exceptions, but setTitle() function doesn’t update text in TextView title! In log I can see that title stores “123” after executing the last row in setTitle(). But the value doesn’t update on the screen! How can I fix it?

Answer 1

Pass the original reference to the TextView instead of the context to the Activity and then calling setText on the TextView, should work 😉
