Android Multithreading With Textwatcher

I'm fairly new to Android development and am currently working on an app that allows people to type text into a box and the text is displayed on a Bitmap on screen. I have a text b

Solution 1:

You can use AsyncTask to do things in the background

publicvoid afterTextChanged(final Editable editable) {
    new AsyncTask<Void, Void, Void>() {
        protectedVoid doInBackground(Void... params) {
            pic.setText(editable.toString());
            pic.writeText();
            returnnull;
        }
        protectedvoid onPostExecute(Void result) {
            imageView.setImageBitmap(pic.getImage());
        }            
    }.execute();
}

You have to remember that now pic.setText(editable.toString());pic.writeText(); may be called simultaneously multiple times if the user typing fast and writetext is slow.
