In the development of Android, onclicklistener for click events has the following four implementation methods, and the appropriate usage can be selected according to the needs of the actual scene. The button button button is used as an example.

Method 1:

Method 2:

Suitable for scenario: it is suitable for multiple controls of the same type (such as button array) to implement onclick () method

Method 3:
