Android中回调接口使用实例

MainActivity如下:

package cc.cn;import cc.cn.ThreadSubclass.YourListener;import android.app.Activity;import android.os.Bundle;/** * Demo描述: * Android中回调接口使用实例 */public class MainActivity extends Activity {private ThreadSubclass mThreadSubclass;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        init();    }        private void init(){    mThreadSubclass=new ThreadSubclass();    mThreadSubclass.setYourListener(new YourListener() {@Overridepublic void onSomeChange(String info,int i) {System.out.println("------> info="+info);System.out.println("------> i="+i);}});    mThreadSubclass.start();    }    }

ThreadSubclass如下:

package cc.cn;public class ThreadSubclass extends Thread {private YourListener mYourListener=null;@Overridepublic void run() {super.run();        for (int i = 0; i < 5; i++) {System.out.println("Now is "+i);}        if (mYourListener!=null) {        mYourListener.onSomeChange("输入已经完毕",9527);}}    //回调接口(监听器)public interface YourListener {public void onSomeChange(String info,int i);}//设置回调接口(监听器)的方法public void setYourListener(YourListener yourListener) {mYourListener = yourListener;}}

main.xml如下:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="Android中回调接口使用实例"        android:layout_centerInParent="true" />    </RelativeLayout>
