我使用的Andr​​oid设计支持库的TabLayout。我使用的材料的设计主题。下面是code

I am using the TabLayout from Android Design support library. I am using material design theme. Below is the code

activity_scrollable_Tab.xml

activity_scrollable_Tab.xml

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

 <android.support.design.widget.AppBarLayout

<android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabMode="scrollable"/>

    </android.support.design.widget.AppBarLayout>

   <android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</android.support.design.widget.CoordinatorLayout>

scrollableTabActivity.java

scrollableTabActivity.java

public class ScrollableTabsActivity extends AppCompatActivity {

    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scrollable_tabs);

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
    }

    private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new OneFragment(), "ONE");
        adapter.addFrag(new TwoFragment(), "TWO");
        .....
        adapter.addFrag(new TenFragment(), "TEN");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFrag(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
}

标签滚动工作在棒棒糖。但是，同样的code未工作的奇巧和果冻豆设备。在奇巧和果冻豆设备我面临两个问题，

Tab scrolling is working in Lollipop. But the same code is not working on Kitkat and Jelly bean devices. On Kitkat and Jelly bean device I face two problem,

1. 当我滚动标签，标签沿着与杰利贝恩和奇巧设备页面导航滚动，但棒棒堂选项卡单独获得滚动，它是工作文件。对于例如：如果1,2,3..10是选项卡，如果我滚动标签，它滚动，每个滚动布局被导航。如果我滚动，标签获取导航到第二个选项卡，然后第三个等。

1. When I scroll the Tab, Tab is scrolling along with page navigation in Jellybean and kitkat devices, but in Lollipop Tab alone gets scroll and it is working file. For eg: if 1,2,3..10 are the Tab and if I scroll the Tab, it scroll and for each scroll the Layout gets navigated. If I scroll, Tab gets navigate to 2nd Tab and then 3rd and so on.

向上导航不杰利贝恩和奇巧的设备工作。如果我刷工具栏，标签滚动与页面导航发生（上面提到的问题）。

Up navigation is not working in Jellybean and Kitkat devices. If I swipe the Toolbar, Tab scrolling is happening with page navigation (above-mentioned issue).

谁能告诉我可能是什么问题，并在部分我需要检查和排序。我公司可以派APK文件，如果我提供的电子邮件以更好地理解这个问题。

Can anyone tell me what could be the problem and in which portion I need to check and sort it. I can send APK file if provide me the email for a better understanding of the problem.

我是新到Android，需要一些帮助来解决这个问题。

I am new to android, need some help to fix this.
