这篇博客展示了如何在Android应用中实现PagerSlidingTabView与ViewPager的联动，通过创建FragmentPagerAdapter，设置标题并实例化Fragment，实现导航条与内容页的同步切换。同时，提供了改变导航条颜色的方法。

android导航条与viewpager联动

package net.xinhuamm.horizontalscroll.simple;

import net.xinhuamm.horizontalscroll.view.PagerSlidingTabView;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

public class HsViewActivity extends FragmentActivity {
private PagerSlidingTabView tabs;
private ViewPager pager;
private MyPagerAdapter adapter;
//主题颜色,修改后文字和下面的移动条统一修改
private int currentColor = 0xffE60012;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.hs_view_activity_main);
tabs = (PagerSlidingTabView) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new MyPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
tabs.setViewPager(pager);
changeColor(currentColor);
}

private void changeColor(int newColor) {
tabs.setIndicatorColor(newColor);
currentColor = newColor;
}
public class MyPagerAdapter extends FragmentPagerAdapter {
private final String[] TITLES = { "头条", "科技", "手机","移动互联网","数码"};
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public CharSequence getPageTitle(int position) {
return TITLES[position];
}

@Override
public int getCount() {
return TITLES.length;
}

@Override
public Fragment getItem(int position) {
return TextCardFragment.newInstance(TITLES[position]);
}
}
}
