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 ：
package com.zzw.testsetcustomtabcolorizer; import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction; public class MainActivity extends FragmentActivity { @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); if (savedInstanceState == null) {
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
TabFragment fragment = new TabFragment();
transaction.replace(R.id.content_fragment, fragment);
transaction.commit();
}
}
}
MainActivity.java需要的布局文件：activity_main.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.zzw.testsetcustomtabcolorizer.MainActivity" > <FrameLayout
android:id="@+id/content_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" /> </RelativeLayout>
TabFragment.java代码文件：
package com.zzw.testsetcustomtabcolorizer; import java.util.ArrayList; import com.zzw.testsetcustomtabcolorizer.SlidingTabLayout.TabColorizer; import android.graphics.Color;
import android.os.Bundle;

this.mTitle = mTitle;
this.mIndicatorColor = mIndicatorColor;
this.mDividerColor = mDividerColor;
} public Fragment createFragment() {
return ContentFragment.newInstance(mTitle, mIndicatorColor,
mDividerColor); } public CharSequence getTitle() {
return mTitle;
} public int getIndicatorColor() {
return mIndicatorColor;
} public int getDividerColor() {
return mDividerColor;
}
} private ArrayList<PagerItem> mTabCards = new ArrayList<PagerItem>(); public static class ContentFragment extends Fragment {
private static final String KEY_TITLE = "title";
private static final String KEY_INDICATOR_COLOR = "indicator_color";
private static final String KEY_DIVIDER_COLOR = "divider_color"; public static ContentFragment newInstance(CharSequence title,
int indicatorColor, int dividerColor) {
Bundle bundle = new Bundle();
bundle.putCharSequence(KEY_TITLE, title);
bundle.putInt(KEY_INDICATOR_COLOR, indicatorColor);
bundle.putInt(KEY_DIVIDER_COLOR, dividerColor); ContentFragment fragment = new ContentFragment();
fragment.setArguments(bundle); return fragment;
} @Override
@Nullable
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container,
@Nullable Bundle savedInstanceState) { TextView tv = new TextView(getActivity());
tv.setGravity(Gravity.CENTER); return tv;
} @Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
TextView tv = (TextView) view; Bundle args = getArguments(); String content = "";
if (args != null) {
String title = args.getCharSequence(KEY_TITLE) + ""; int indicatorColor = args.getInt(KEY_INDICATOR_COLOR);
String indicatorColors = Integer.toHexString(indicatorColor)

}
tv.setText(content);
} } @Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState); mTabCards.add(new PagerItem("Tab A", Color.RED, Color.RED));
mTabCards.add(new PagerItem("Tab B", Color.YELLOW, Color.YELLOW));
mTabCards.add(new PagerItem("Tab C", Color.GREEN, Color.GREEN));
mTabCards.add(new PagerItem("Tab D", Color.BLUE, Color.BLUE));
mTabCards.add(new PagerItem("Tab E", Color.CYAN, Color.CYAN));
mTabCards.add(new PagerItem("Tab F", Color.MAGENTA, Color.MAGENTA));
} @Override
@Nullable
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment, null);
} @Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
ViewPager mViewPager = (ViewPager) view.findViewById(R.id.viewpager);
mViewPager.setAdapter(new MyFragmentPagerAdapter(
getChildFragmentManager())); SlidingTabLayout mSlidingTabLayout = (SlidingTabLayout) view
.findViewById(R.id.sliding_tabs);
mSlidingTabLayout.setViewPager(mViewPager);
//设置颜色的代码
mSlidingTabLayout.setCustomTabColorizer(new TabColorizer() { @Override
public int getIndicatorColor(int position) {
return mTabCards.get(position).getIndicatorColor();
} @Override
public int getDividerColor(int position) { return mTabCards.get(position).getDividerColor();
}
}); } public class MyFragmentPagerAdapter extends FragmentPagerAdapter { public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
} @Override
public int getCount() {
return mTabCards.size();
} @Override
public CharSequence getPageTitle(int position) {
return mTabCards.get(position).getTitle();
} @Override
public Fragment getItem(int position) {
return mTabCards.get(position).createFragment();
} }
}
TabFragment.java需要的布局文件fragment.xml文件代码
<?xml version="1.0" encoding="utf-8"?>
