Android AppCompat-v7透明Actionbar 21主题

Question

我试过this。但我面临的问题是与<item name="android:windowActionBarOverlay">true</item>

滑动选项卡后面的操作栏。

（见标志和标题上述标签） 当我设置

android:layout_marginTop="?attr/actionBarSize" 

然后滑动翼片不保持透明。

什么是正确的方式使操作栏透明没有滑动标签后面的操作栏？

编辑： activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background="@drawable/newbg"> 

    <!-- The sliding tab --> 
    <com.github.amitt001.musicapp.stab.SlidingTabLayout 
     android:id="@+id/sliding_tabs" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 

    <!-- The pager that allows us to swipe between fragments --> 
    <android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="0px" 
     android:layout_weight="1" 
     android:background="@android:color/transparent"/><!--#A6000000" --> 
</LinearLayout>

请与工具栏的XML和制表符

tool_bar_tabs.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 
    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:minHeight="?attr/actionBarSize" 
     android:background="@color/ColorPrimary" 
     android:elevation="4dp" 
     app:theme="@style/ToolbarColors"> 

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

    <com.github.amitt001.musicapp.stab.SlidingTabLayout 
     android:id="@+id/sliding_tabs" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 

</RelativeLayout> 

styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> 
     <item name="colorPrimary">@color/ColorPrimary</item> 
     <item name="colorPrimaryDark">@color/ColorPrimaryDark</item> 
    </style> 

您activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background="@drawable/newbg"> 

    <include 
    android:id="@+id/tb_tabs" 
    layout="@layout/tool_bar_tabs"></include> 

    <!-- The pager that allows us to swipe between fragments --> 
    <android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="0px" 
     android:layout_weight="1" 
     android:background="@android:color/transparent"/><!--#A6000000" --> 
</LinearLayout> 

初始化。工具栏，并使其成为动作条在

MainActivity

public class Main extends AppCompatActivity{ 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

      setContentView(R.layout.activity_main); 

      Toolbar tb = (Toolbar) findViewById(R.id.tool_bar); 
      setSupportActionBar(tb); 
}
