自定义viewpager

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class MyViewPager extends ViewPager {


   private float x1;
   private float y1;

   public MyViewPager(Context context) {
       super(context);
       // TODO Auto-generated constructor stub
   }

   public MyViewPager(Context context, AttributeSet attrs) {
       super(context, attrs);
       // TODO Auto-generated constructor stub

       switch (ev.getAction()) {
       case MotionEvent.ACTION_DOWN:
           x1=ev.getX();
           y1=ev.getY();
           getParent().requestDisallowInterceptTouchEvent(true);

偶然发现，ScrollView的滑动效果出不来，经过很多试验，发现是在我的Activity当中，我使用了如下的代码段：

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);

。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

       lv.setOnTouchListener(new View.OnTouchListener() {

           @Override
           public boolean onTouch(View v, MotionEvent event) {
               if (event.getAction() == MotionEvent.ACTION_UP) {
                   sv.requestDisallowInterceptTouchEvent(false);
               } else {
                   sv.requestDisallowInterceptTouchEvent(true);
               }
               return false;
           }
       });

===================================计时器当中更新UI============================

            Timer timer=new Timer();
       timer.schedule(new TimerTask() {
           @Override
           public void run() {
               runOnUiThread(new Runnable() {
                   @Override
                   public void run() {
                       vp.setCurrentItem(vp.getCurrentItem()+1);
                   }
               });

           }
       },0,2000);
