此篇博客主要详细介绍时下比较流行的两个android开源组件的使用，AnctionBarsherlock与viewpagerindicator，具体使用将以demo形式呈现，先上效果图，看是否是你需要的。

一步：下载资源，github 是好东东。

这是两个开源组件的Github地址，具体你想用Git同步还是svn，自选

https://github.com/JakeWharton/ActionBarSherlock

https://github.com/JakeWharton/Android-ViewPagerIndicator

二步：开始工程的配置和组件的使用。在工程右击--properties --android 添加Library

添加viewpagerindicator组件的布局文件simple_tabs.xml

Xml代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.viewpagerindicator.TabPageIndicator
android:id="@+id/indicator"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
/>
</LinearLayout>

添加Fragments的布局文件

Xml代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

创建 TabDemoActivity继承sherlockFragmentActivity

Java代码

package com.example.blogsit;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.viewpagerindicator.PageIndicator;
import com.viewpagerindicator.TabPageIndicator;
/**
* 微博 : @陈华blogsit
* @author blogsit.cn
*
*/
public class TabDemoActivity extends SherlockFragmentActivity {
private static final String[] CONTENT = new String[] { "分组一", "分组二", "分组三", "分组四", "分组五" };
TabFragmentAdapter mAdapter;
ViewPager mPager;
PageIndicator mIndicator;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_tabs);
mAdapter = new TabFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (TabPageIndicator)findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
}
class TabFragmentAdapter extends FragmentPagerAdapter {
private int mCount = CONTENT.length;
public TabFragmentAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return TabFragment.newInstance(String.valueOf(position));
}
@Override
public int getCount() {
return mCount;
}
@Override
public CharSequence getPageTitle(int position) {
return CONTENT[position];
}
}
}

添加Fragment子类TabFragment

Java代码

package com.example.blogsit;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.viewpagerindicator.PageIndicator;
import com.viewpagerindicator.TabPageIndicator;
/**
* 微博 : @陈华blogsit
* @author blogsit.cn
*
*/
public class TabDemoActivity extends SherlockFragmentActivity {
private static final String[] CONTENT = new String[] { "分组一", "分组二", "分组三", "分组四", "分组五" };
TabFragmentAdapter mAdapter;
ViewPager mPager;
PageIndicator mIndicator;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_tabs);
mAdapter = new TabFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (TabPageIndicator)findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
}
class TabFragmentAdapter extends FragmentPagerAdapter {
private int mCount = CONTENT.length;
public TabFragmentAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return TabFragment.newInstance(String.valueOf(position));
}
@Override
public int getCount() {
return mCount;
}
@Override
public CharSequence getPageTitle(int position) {
return CONTENT[position];
}
}
}

使用Fragment方便管理tab页，viewpagerindicator使用场景非常常见，在很多应用的重新安装的开始引导页中也可以用到。具体实例在Viewpageridicator的Github的samplelist中有详细介绍。请关注 @陈华blogist 微博，有使用问题微博交流，其实下面有详细的代码，上图是实际运行效果。并在产品中已经使用。
