重写父viewpager
在父ViewPager覆盖canScroll：
@Overrideprotected boolean canScroll(View v, boolean checkV, int dx, int x, int y) {   if(v != this && v instanceof ViewPager) {      return true;   }   return super.canScroll(v, checkV, dx, x, y);}自定义父ViewPagerpackage com.example.viewpager_demo_qiantao;import android.content.Context;import android.support.v4.view.ViewPager;import android.util.AttributeSet;import android.view.View;public
