ViewPager 使用一

package com.example.viewpager;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.view.PagerTabStrip;
import android.support.v4.view.ViewPager;
import android.view.View;

public class MainActivity extends Activity {

    private List<View> viewList;
    private ViewPager pager;
    private PagerTabStrip tab;
    private List<String> titleList;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewList = new ArrayList<View>();
        View view1 = View.inflate(this, R.layout.view1, null);
        View view2 = View.inflate(this, R.layout.view2, null);
        View view3 = View.inflate(this, R.layout.view3, null);
        View view4 = View.inflate(this, R.layout.view4, null);

        viewList.add(view1);
        viewList.add(view2);
        viewList.add(view3);
        viewList.add(view4);
        
        //为页卡设置标题
        titleList = new ArrayList<String>();
        titleList.add("第一页");
        titleList.add("第二页");
        titleList.add("第三页");
        titleList.add("第四页");
        
        tab = (PagerTabStrip) findViewById(R.id.pagerTitle);
        //为PageTabStrip设置一些属性
        tab.setBackgroundColor(Color.YELLOW);
        tab.setTextColor(Color.RED);
        tab.setDrawFullUnderline(false);
        tab.setTabIndicatorColor(Color.GREEN);
        
        pager = (ViewPager) findViewById(R.id.pager);
        
        //创建PagerAdapter的适配器
        MyPagerAdapter adapter = new MyPagerAdapter(viewList,titleList);
        //Viewpage加载适配器
        pager.setAdapter(adapter);

    }

}

xml文件：

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" >

        <android.support.v4.view.PagerTabStrip
            android:id="@+id/pagerTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="top" >
        </android.support.v4.view.PagerTabStrip>
    </android.support.v4.view.ViewPager>

</RelativeLayout>

view1.xml文件和view2，3,4文件：

<?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/textView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical|center_horizontal"
        android:text="第一个界面" />

</LinearLayout>

一样的！
