android中修改tablayout中的字体大小和颜色

两种方法：

1: 直接通过下面的设置

<android.support.design.widget.TabLayout
android:id="@+id/tablayout_video"
android:layout_width="match_parent"
android:layout_height="@dimen/tablayout_height"
app:tabBackground="@drawable/tablayout_background"
app:tabIndicatorHeight="0dp"
app:tabSelectedTextColor="@color/white"
app:tabTextAppearance="@style/TabLayoutTextStyle"
app:tabTextColor="@color/white" />

2: 通过styles

两步骤：

      1: 首先在values文件夹中的styles.xml文件中，如下的内容，具体的什么颜色和字体可以再修改

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textSize">20sp</item>
<item name="android:textColor">@android:color/holo_blue_dark</item>
</style>
<style name="MyTabLayoutTextAppearanceInverse" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
<item name="android:textSize">15sp</item>
<item name="android:textColor">@android:color/holo_red_light</item>
</style>

添加后的styles 应该是下面这样的：

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textSize">20sp</item>
<item name="android:textColor">@android:color/holo_blue_dark</item>
</style>
<style name="MyTabLayoutTextAppearanceInverse" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
<item name="android:textSize">15sp</item>
<item name="android:textColor">@android:color/holo_red_light</item>
</style>

</resources>

2: 然后在我们tablayout 布局里面调用就可以了，其实就一句话：

app:tabTextAppearance="@style/MyTabLayoutTextAppearance"

<android.support.design.widget.TabLayout
android:id="@+id/tablayout"
android:visibility="gone"
android:layout_width="match_parent"
android:layout_height="100dp"
app:tabTextAppearance="@style/MyTabLayoutTextAppearance"
/>
