Question

How do you implement this onTouchEvent? It should fire when the user checks or unchecks the CheckBox widget.

CheckBox checkBox = new CheckBox(activity);
checkBox.setText("Don't present me information again.");
checkBox.onTouchEvent(.....);

Answer 1

The CheckBox widget (and any other widget that extends CompoundButton) has a method setOnCheckedChangeListener, which is the bit you’re lacking (you probably don’t want to use onTouchEvent in this case).

This example should replace the final line of code in your snippet:

checkBox.setOnCheckedChangeListener( new OnCheckedChangeListener() {
  public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if ( isChecked ) {
      // do some stuff
    }
  }
});
