//利用定时器实现图片的联动

public class MainActivity extends Activity {public static ImageView imageView ;private Timer timer;private ImageAdapter adapter;private Gallery gallery;private ImageView imgPoint;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.home_activity);        imgPoint = (ImageView) this.findViewById(R.id.imgPoint);        imgPoint.setBackgroundResource(R.drawable.slide_adv_selected);        gallery =  (Gallery) this.findViewById(R.id.gallery);        adapter = new ImageAdapter(this);        gallery.setAdapter(adapter);        gallery.setSpacing(1);        //线程控制部分        TimerTask task = new TimerTask() {@Overridepublic void run() {gallery.onFling(null, null, -750, 0);}};timer = new Timer();timer.schedule(task, 3000, 3000);}    @Override    protected void onDestroy() {    timer.cancel();    super.onDestroy();    }}
