Android SlidingTabLayout默认的滑动指示条是系统默认的某个蓝色系色值，分割线是灰色。如果要自定义实现滑动指示条和分割线定制颜色，则主要通过SlidingTabLayout的setCustomTabColorizer()方法实现。
现在给出一个例子加以说明。
（1）首先做一个MainActivity，此MainActivity没有实质意义，只是作为第二步加载要实现SlidingTabLayout Fragment的“容器”。
（2）在一个Fragment实现SlidingTabLayout，然后将此Fragment加载。
不要忘记引用Android官方实现的SlidingTabLayout和SlidingTabStrip。
代码层次结构如图所示：
测试用的主Activity MainActivity.java ：
1 package com.zzw.testsetcustomtabcolorizer; 2 3 import android.os.Bundle; 4 import android.support.v4.app.FragmentActivity; 5 import android.support.v4.app.FragmentTransaction; 6 7 public class MainActivity extends FragmentActivity { 8 9 @Override10 protected void onCreate(Bundle savedInstanceState) {11 super.onCreate(savedInstanceState);12 setContentView(R.layout.activity_main);13 14 if (savedInstanceState == null) {15 FragmentTransaction transaction = getSupportFragmentManager()16 .beginTransaction();17 TabFragment fragment = new TabFragment();18 transaction.replace(R.id.content_fragment, fragment);19 transaction.commit();20 }21 }22 }
MainActivity.java需要的布局文件：activity_main.xml：
1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 2 xmlns:tools="http://schemas.android.com/tools" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 tools:context="com.zzw.testsetcustomtabcolorizer.MainActivity" > 6 7 <FrameLayout 8 android:id="@+id/content_fragment" 9 android:layout_width="match_parent"10 android:layout_height="match_parent" />11 12 </RelativeLayout>
TabFragment.java代码文件：
