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：
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 }
