Questions tagged [android-button]

questions about the android.widget.Button element. This element can be used on activities.

Usually a listener(OnClickListener) is set on the Button to receive an event when the user touches the Button. The listener can be set in code or by using the android:onClick attribute in the xml layout, setting it to point to a method written in the Activity class.
