Androidviewpage实现可控制的禁止滑动

public class MyViewPager extends ViewPager { 

  private boolean scrollble=true; 

  public MyViewPager(Context context){  
    super(context); 
  } 

  public MyViewPager(Context context, AttributeSet attrs) { 
    super(context, attrs); 
  } 


  @Override 
  public boolean onTouchEvent(MotionEvent ev) { 
    if (!scrollble) { 
      return true; 
    } 
    return super.onTouchEvent(ev); 
  }

  @Override
  public boolean onInterceptTouchEvent(MotionEvent ev) {
    if (scrollble == false) {
      return false;
    } else {
      return super.onInterceptTouchEvent(ev);
    }
  }

  public boolean isScrollble() { 
    return scrollble; 
  } 

  public void setScrollble(boolean scrollble) { 
    this.scrollble = scrollble; 
  } 
}
