Four kinds of onclick response methods for Android learning-button

In Android or Java development, there are four ways to implement the button's Onclicklistener, and you can choose the appropriate usage as needed.

Method One:

Fit Scene: Universal

Button Bt_demo = (button) Findviewbyid (R.id.bt_demo);  Bt_demo.setonclicklistener (New Onclicklistener () {@Override public void OnClick (View v) {///Response clicked Event//... } });

Method Two:

Fit for scene: used when multiple button or button arrays are appropriate

Button Bt_demo = (button) Findviewbyid (R.id.bt_demo);  Bt_demo.setonclicklistener (listener); Private Onclicklistener listener = new Onclicklistener () {@Override public void OnClick (View arg0) {//TODO Auto-gen     erated method Stub switch (Arg0.getid ()) {case R.id.bt_demo://Response clicked Event//... break;     Default:break; }  } }

Method Three:

Fit scenario: Used when multiple button or button arrays are appropriate, which is not very different from method two

Button Bt_demo = (button) Findviewbyid (R.id.bt_demo); Bt_demo.setonclicklistener (New Buttonlistener ());    Private class Buttonlistener implements onclicklistener{@Override public void OnClick (View arg0) {//Response clicked Event   //......  } }

Method Four:

Fit scenario: Suitable for different types of controls on the interface, which implements the OnClick method of all controls in a single method, and looks relatively concise

  //directly Onclicklistener interface in activity:     import  android.view.view.onclicklistener;   public class myactivity extends  activity implements onclicklistener {       @Override  public  void oncreate (bundle savedinstancestate)  {     super.oncreate ( Savedinstancestate);      setcontentview (R.layout.main);      Push button      Button bt_Demo =  Findviewbyid (R.id.bt_demo);      bt_demo.setonclicklistener (This);    }       //Response Click event    public void onclick (VIEW V)  {        switch  (V.getid ())  {           case r.id.bt_demo:      //responding to clicked Events      //......            break;          default:            break;       }     }     }
