ViewPager(横向滑动菜单) 实现Demo

1.首先去（http://download.csdn.net/detail/dm_jc/9558346）下载需要的依赖库，将程序与下载的依赖库结合

2.引用所依赖的类（包名+类名）

<span style="color:#ff0000;"> <com.viewpagerindicator.TabPageIndicator
android:id="@+id/indicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/base_action_bar_bg" /></span>

<android.support.v4.view.ViewPager
android:id="@+id/main_viewpager"
android:layout_width="fill_parent"
android:layout_height="match_parent" />

3.为ViewPager创建适配器，这里ViewPager的item是Fragment

package com.zjc.Adapter;

import com.zjc.Fragment.Main_ViewPager_Fragment;
import com.zjc.Util.Util;

import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class Main_vp_fragment_Adapter extends FragmentPagerAdapter {

public Main_vp_fragment_Adapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}

@Override
public Fragment getItem(int arg0) {
// 新建一个Fragment来展示ViewPager item的内容，并传递参数
Fragment fragment = new Main_ViewPager_Fragment();
Bundle args = new Bundle();
args.putInt("arg", arg0);
fragment.setArguments(args);
return fragment;
}

@Override
public CharSequence getPageTitle(int position) {

return Util.News_types[position % Util.News_types.length];

}

@Override
public int getCount() {
// TODO Auto-generated method stub
return Util.News_types.length;
}

}

</pre><p></p><pre>

4.将ViewPager与引入的TabPageIndicator进行关联

// 给ViewPager添加适配器
Main_vp_fragment_Adapter fragment_Adapter = new Main_vp_fragment_Adapter(
getSupportFragmentManager());
main_vp.setAdapter(fragment_Adapter);
// 实例化TabPageIndicator然后设置ViewPager与之关联
TabPageIndicator indicator = (TabPageIndicator) findViewById(R.id.indicator);
indicator.setViewPager(main_vp);
