ViewPager嵌套ListView，viewpager无法滑动

ViewPager 嵌套ListView，listView可以点击，viewpager不能滑动，怎么办？？？
viewpager自定义：
@Override
public boolean onTouchEvent(MotionEvent ev) {
// TODO Auto-generated method stub
L.i(TAG, "onTouchEvent");
return super.onTouchEvent(ev);
}

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    // TODO Auto-generated method stub
    L.i(TAG, "dispatchTouchEvent");
    boolean ret = super.dispatchTouchEvent(ev);
    if (ret) {
        requestDisallowInterceptTouchEvent(true);
    } else
        requestDisallowInterceptTouchEvent(false);
    return ret;
}
ListView:
@Override
public boolean onTouchEvent(MotionEvent event) {
    // TODO Auto-generated method stub
    L.i(TAG, "onTouchEvent");
    return super.onTouchEvent(event);
}

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    // TODO Auto-generated method stub
    L.i(TAG, "dispatchTouchEvent");
    return super.dispatchTouchEvent(ev);
}
大神们，怎么办啊？？？
