android中修改tablayout中的字体大小和颜色

按步骤来吧。

一、activity_main.xml：

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

二、values/styles.xml:

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

三、MainActivity.java：

TabLayout tabLayout=(TabLayout)findViewById(R.id.tablayout);        ViewPager viewPager=(ViewPager)findViewById(R.id.viewpager);        if(viewPager!=null)        {            Fragment1 fragment1=new Fragment1();            Fragment2 fragment2=new Fragment2();            FragmentAdapter adapter=new FragmentAdapter(getSupportFragmentManager());            adapter.addFragment(fragment1,"字体");            adapter.addFragment(fragment2,"颜色");            viewPager.setAdapter(adapter);            tabLayout.setupWithViewPager(viewPager);        }
