android 工程代码：

}
};


private static void Test() {
// TODO Auto-generated method stub

}

//实现接口：

import android.content.Context;
import android.widget.Toast;


public class Test implements testInterface {

public Test(Context context) {
super();

}


@Override
public void Test() {
// TODO Auto-generated method stub
// Toast.makeText(activity, "", Toast.LENGTH_SHORT).show();
System.out.println("调用自定义接口已实现");
MainActivity.handler.sendMessage(MainActivity.handler.obtainMessage(0));
}
}
