解决办法自然是try catch大法

    @Override
    protected void dispatchDraw(Canvas canvas) {
        try {
            super.dispatchDraw(canvas);
        } catch (IndexOutOfBoundsException e) {
            // samsung error
        }
    }

2、ViewPager通过构造器创建添加到布局的时候，抛异常

android.content.res.Resources$NotFoundException: Unable to find resource ID #0xffffffff

解决办法是，给ViewPager添加一个id，就不会抛异常了。具体操作是新建一个ids.xml，里面定义一个id，之后引用这个id。

<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <item type="id" name="vp_id"/>
</resources>

mViewPager.setId(R.id.vp_id);
