本文分享了一个关于Android开发中使用Fragment与TabLayout的具体实践案例，通过实例代码展示了如何实现带有自定义Tab指示器的FragmentTabHost，并解决了相关布局警告问题。

我个人觉得这个与fragment4 5是一样的，但是之前有三个项目中就是这样用的，没有出现问题，有必要拿出来分享下。

涉及到原项目，就不放图片了。

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

    <FrameLayout
        android:id="@+id/fragment_tabcontent"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">
    </FrameLayout>
    <!-- 导航条-->
    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@android:color/darker_gray"/>
    <android.support.v4.app.FragmentTabHost
        android:id="@+id/fragment_tabhost"
        android:layout_width="match_parent"
        android:layout_height="56dp">
    </android.support.v4.app.FragmentTabHost>
</LinearLayout>

这个布局会有警告，可以用这个方法解决（我没有进行优化，警告仍然正常跑项目，现在既然把代码贴上来，把解决办法写下）

<!--定义FragmentTabHost控件-->
    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/black" ><!--装4个Fragment-->

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" /><!--装Tab的内容-->
    </android.support.v4.app.FragmentTabHost>
