Android SlidingTabLayout默認的滑動指示條是系統默認的某個藍色系色值，分割線是灰色。如果要自定義實現滑動指示條和分割線定制顏色，則主要通過SlidingTabLayout的setCustomTabColorizer()方法實現。
現在給出一個例子加以說明。
（1）首先做一個MainActivity，此MainActivity沒有實質意義，只是作為第二步加載要實現SlidingTabLayout Fragment的“容器”。
（2）在一個Fragment實現SlidingTabLayout，然後將此Fragment加載。
不要忘記引用Android官方實現的SlidingTabLayout和SlidingTabStrip。
代碼層次結構如圖所示：
測試用的主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 @Override
10 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代碼文件：
