推荐答案

使用设计支持库的http://android-developers.blogspot.in/2015/05/android-design-support-library.html

这包括在的build.gradle

include this in build.gradle

compile 'com.android.support:design:22.2.0'    
compile 'com.android.support:appcompat-v7:22.2.+'

有关回收视图包含这也是​​

for recycler view include this also

compile 'com.android.support:recyclerview-v7:22.2.0' 

    

    <!-- AppBarLayout allows your Toolbar and other views (such as tabs provided by TabLayout) 
    to react to scroll events in a sibling view marked with a ScrollingViewBehavior.-->
    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true">

        <!-- specify tag app:layout_scrollFlags -->
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"/>

        <!-- specify tag app:layout_scrollFlags -->
        <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            android:scrollbars="horizontal"
            android:layout_below="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"/>

        <!--  app:layout_collapseMode="pin" will help to pin this view at top when scroll -->
        <TextView
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:text="Title"
            android:gravity="center"
            app:layout_collapseMode="pin" />

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

    <!-- This will be your scrolling view. 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" tag connects this features -->
    <android.support.v7.widget.RecyclerView
        android:id="@+id/list"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </android.support.v7.widget.RecyclerView>

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

您活动应该延长 AppCompatActivity

public class YourActivity extends AppCompatActivity {

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

        //set toolbar
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
    }

}

您的应用程序的主题应该是这样的。

Your app theme should be like this

    <resources>
            <!-- Base application theme. -->   
            <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
            </style>
    </resources>
