带有视图页的选项卡布局不平滑滚动

编辑

我已按照这些教程来解决此问题。

但是，在尝试了几种解决方案后，这个问题仍然存在，这很烦人。这是我面临的问题的演示。自从我在这个问题上陷入困境以来已经有好几周了。

演示链接。

我用于测试的设备是Nexus 4和Nexus 5。

TabLayout与不是滚动平滑。我需要滑动两次才能在下次点击时切换。我环顾了一下网络，但找不到任何解决方案。我正在使用最新的支持设计库。这是 gradle 文件ViewPager

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.3"

defaultConfig {
    applicationId "com.softoven.ultron"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.google.code.gson:gson:2.5'
}

这是活动代码。

private DrawerLayout drawerLayout;
private ViewPager viewPager;
private TabLayout tabLayout;
private NavigationView navigationView;
private CategoriesDTO categoriesDTO;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initToolbar();
    initUi();
    loadCategories();
}

private void initToolbar() {
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_action_menu);
}

private void initUi() {
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
    navigationView = (NavigationView) findViewById(R.id.navigation);
    viewPager = (ViewPager) findViewById(R.id.viewPager);
    tabLayout = (TabLayout) findViewById(R.id.tab);

}

private void loadCategories() {
    StringRequest request = new StringRequest(Constants.URL_GET_CATEGORIES, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            categoriesDTO = Constants.gson.fromJson(response, CategoriesDTO.class);
            ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
            viewPager.setOffscreenPageLimit(1);
            viewPager.setAdapter(adapter);
            setTabLayout();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });

    ApplicationController.getmInstance().addToRequestQueue(request);
}

private void setTabLayout() {

    tabLayout.setupWithViewPager(viewPager);

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.home_side_menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    switch (id) {
        case android.R.id.home:
            drawerLayout.openDrawer(GravityCompat.START);
            return true;
    }
    return super.onOptionsItemSelected(item);
}

private class ViewPagerAdapter extends FragmentPagerAdapter {

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

    @Override
    public Fragment getItem(int position) {
        return new ContentFragment();
    }

    @Override
    public int getCount() {
        return 10;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        String title = categoriesDTO.getCategories().get(position).getTitle();
        return (CharSequence) title;
    }
}

和 xml 文件

<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include
            android:id="@+id/toolbar"
            layout="@layout/toolbar"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tab"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabTextColor="#fff"
            app:tabGravity="fill"
            app:tabMode="scrollable"
            >

        </android.support.design.widget.TabLayout>
    </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.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/navigation"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:menu="@menu/home_drawer_menu">

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

这是你可以看到指标被部分分割的屏幕截图。

任何解决方案？
