Android Setonclicklistener callback function understanding

1. Simulate the Java view class:

Package com.test;/** * Created by Dandan on 15-2-7. */public class View {    /** set default id**/public    static final int no_id =-1;    /** sets the ID of each control for the quilt class override **/public    int mID = no_id;    /** Save Click Callback function **/public    onclicklistener Monclicklistener;    Public interface Onclicklistener {        void OnClick (view view);    };    void Setonclicklistener (Onclicklistener onclicklistener) {        this.monclicklistener = Onclicklistener;    };    public int getId () {        return mID;    };} <span style= "color: #ff0000;" ></span>

2. Simulate Android control to inherit view

Package com.test;/** * Created by Dandan on 15-2-7. */public class Animationbutton extends  view{    /**     * Button Subclass simulates the way a user clicks     *     * **/public    void Moniclick () {        this.mid =;        Onclicklistener clicklistener = This.monclicklistener;        Clicklistener.onclick (this);}    }

3. Impersonate a client using the Animationbutton control

Package com.test;/** * Created by Dandan on 15-2-7. */public class Mainactivity {public    static void Main (string[] args) {        Animationbutton Animationbutton = new Anima Tionbutton ();        Animationbutton.setonclicklistener (New View.onclicklistener () {            @Override public            void OnClick (view view) {                System.out.print (View.getid ());            }        );

<span style= "White-space:pre" ></span>//analog User click button        animationbutton.moniclick ();}    }
