Question

我有2个片段的ViewPager NonSwipeable（无法刷卡）。在第二个片段中，我使用Tab Indicator设置了正常的ViewPager（可以滑动）。但是，当我刷那个ViewPager时，它的外观滞后。

家长活动

public NonSwipeableViewPager mPager;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);y;
        setContentView(R.layout.activity_search);

....

mAdapter = new FragmentSearchAdapter(getSupportFragmentManager(), SearchActivity.this);
        mAdapter.addFragment("search histori");
        mAdapter.addFragment("search result");

        mPager.setAdapter(mAdapter);
        mPager.setOffscreenPageLimit(2);

....

}

这是Custom ViewPager NonSwipeable：

 public class NonSwipeableViewPager extends ViewPager {

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

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

        @Override
        public boolean onInterceptTouchEvent(MotionEvent event) {
            // Never allow swiping to switch between pages
            return false;
        }

        @Override
        public boolean onTouchEvent(MotionEvent event) {
            // Never allow swiping to switch between pages
            return false;
        }
    }

第二片段

 @Bind(R.id.pager)
    public ViewPager mPager;
    @Bind(R.id.tabs)
    PagerSlidingTabStrip mPagerSlidingTabStrip;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        if (container == null) {
            return null;
        }
        View rootView = inflater.inflate(R.layout.fragment_search_result2, container, false);

        mAdapter = new FragmentSearchResultAdapter(getActivity().getSupportFragmentManager(), getActivity());
        mAdapter.addFragment("Business");
        mAdapter.addFragment("Product");
        mPager.setAdapter(mAdapter);
        mPager.setOffscreenPageLimit(2);
        mPagerSlidingTabStrip.setViewPager(mPager);
        return rootView;

    }

那怎么解决呢？对不起我的英文

Answer 1

我的问题是：

 mAdapter = new FragmentSearchResultAdapter(getActivity().getSupportFragmentManager(), getActivity());

我改变：

mAdapter = new FragmentSearchResultAdapter(getChildFragmentManager(), getActivity());

滑动ViewPager仍然落后于内部NonSwipeableViewPager Android
