You just have to override android:textAppearance style. Because TabLayout use textAppearance. here is the small snippet code of style.

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Below will reference with our custom style -->
<item name="android:textAppearance">@style/my_tab_text</item>
</style>


<style name="my_tab_text" parent="Base.TextAppearance.AppCompat">
<item name="android:textColor">@android:color/holo_blue_dark</item>
</style>

And if you dont want to reference from your Apptheme you can directly specify to TabLayout using Below snippet.

 <android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabTextAppearance="@style/my_tab_text"
app:tabIndicatorHeight="48dp"/>

Here is snippet code to override text style and selected text color

<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
<item name="tabTextAppearance">@style/MyCustomTabText</item>
<item name="tabSelectedTextColor">@color/tab_text_act</item>
</style>


<style name="MyCustomTabText" parent="TextAppearance.AppCompat.Button">
<item name="android:textSize">14sp</item>
<item name="android:textColor">@color/tab_text</item>
</style>

And here is snippet code for layout

<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/MyCustomTabLayout" />

最佳答案

Via XML attributes:

<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
app:tabTextColor="@color/your_unselected_text_color"
app:tabSelectedTextColor="@color/your_selected_text_color"/>

Additionally, there are attributes like tabIndicatorColor or tabIndicatorHeight for further styling.

In code:

tabLayout.setTabTextColors(
getResources().getColor(R.color.your_unselected_text_color),
getResources().getColor(R.color.your_selected_text_color)
);

Since this old way is deprecated as of API 23, the alternative is:

tabLayout.setTabTextColors(
ContextCompat.getColor(context, R.color.your_unselected_text_color),
ContextCompat.getColor(context, R.color.your_selected_text_color)
);

All the answers above are correct but I just think its better to override the default styles and only change the specific element you want to change. Example below will make the text bold:

<style name="Widget.TabItem" parent="TextAppearance.Design.Tab">
<item name="android:textStyle">bold</item>
</style>

Then..,

app:tabTextAppearance="@style/Widget.TabItem"

For custom tabs we have to override the following : 1) app:tabTextColor //for_unselected_text"

        <android.support.design.widget.TabLayout
android:id="@+id/tabs"
style="@style/MyCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="?attr/colorPrimary"
android:scrollbarSize="24sp"
android:visibility="gone"
app:tabTextColor="@color/white_40_percent"
app:tabMode="scrollable" />

2) tabSelectedTextColor // for selected tab color 3) tabIndicatorColor // color for tab indicator

   <style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
<item name="android:textColorPrimary">@color/white</item>
<item name="tabSelectedTextColor">@color/white</item>
<item name="tabTextAppearance">@style/TabTextStyle</item>
<item name="tabIndicatorColor">?attr/colorAccent</item>
<item name="tabIndicatorHeight">4dp</item>
<item name="android:tabStripEnabled">true</item>
<item name="android:padding">0dp</item>
</style>






<style name="TabTextStyle">
<item name="android:fontFamily">@string/font_fontFamily_medium</item>
<item name="android:textStyle">bold</item>
<item name="android:textAllCaps">true</item>
<item name="android:textColor">@color/tab_text_color</item>
<item name="android:textSize">16sp</item>
</style>

tab_text_color.xml

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/white_40_percent"android:state_selected="false"/>
<item android:color="@color/white_100_percent"android:state_selected="true"/>
</selector>

Easy and Perfect way:

In xml file ::

<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabTextAppearance="@style/TabText"/>

In values-styles file:

note: "cairo_semibold" is an external font, you can replace it with your font.

<style name="TabText" parent="TextAppearance.Design.Tab">
<item name="android:textColor">#1f57ff</item>
<item name="android:textSize">14sp</item>
<item name="android:fontFamily">@font/cairo_semibold</item>
</style>

best or short and simple way is make custom appbar like

 <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="@color/colorAccent"
app:theme="@style/myCustomAppBarTheme"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark"><RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">


<ImageButton
android:id="@+id/btn_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:background="@android:color/transparent"
android:src="@mipmap/ic_launcher" />


<TextView
android:id="@+id/txt_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:layout_toEndOf="@+id/btn_back"
android:layout_toRightOf="@+id/btn_back"
android:text="Title"
android:textColor="@android:color/white"
android:textSize="20sp"
android:textStyle="bold" />


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

With the TabLayout provided in the Material Components Library you can:

  • Use a custom style 
  <com.google.android.material.tabs.TabLayout
style="@style/My_Tablayout"
..>

and in your style use the tabTextColor with a selector.

<!-- TabLayout -->
<style name="My_Tablayout" parent="Widget.MaterialComponents.TabLayout" >
<item name="tabTextColor">@color/tab_layout_selector</item>
</style>




<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="?attr/colorPrimary" android:state_selected="true"/>
<item android:alpha="0.60" android:color="?attr/colorOnSurface"/>
</selector>
  • Use the app:tabTextColor in your layout:
  <com.google.android.material.tabs.TabLayout
app:tabTextColor="@color/tab_layout_selector"
..>

XML attributes

<com.google.android.material.tabs.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabIndicatorColor="@color/white"
app:tabBackground="@color/colorAccent"
app:tabSelectedTextColor="@color/white"
app:tabTextColor="@color/white"
app:tabMode="scrollable" />

In Kotlin programmatically

(tab_layout as TabLayout).setBackgroundColor(ContextCompat.getColor(mContext, R.color.colorPrimary))
(tab_layout as TabLayout).setSelectedTabIndicatorColor(ContextCompat.getColor(mContext, R.color.white))
(tab_layout as TabLayout).setTabTextColors(ContextCompat.getColor(mContext, R.color.white),
ContextCompat.getColor(mContext, R.color.white))
