说明:
ViewPager用于实现多页面的切换效果,该类存在于Google的兼容包里面,所以在引用时记得在BuilldPath中加入“android-support-v4.jar”
主布局文件
main.xml
其中ViewPager为多页显示控件,PagerTitleStrip用于显示当前页面的标题
主窗口代码:
PagerTitleDemoActivity.java
package com.ns.pager;import java.util.ArrayList;import android.app.Activity;import android.os.Bundle;import android.support.v4.view.PagerAdapter;import android.support.v4.view.PagerTitleStrip;import android.support.v4.view.ViewPager;import android.view.LayoutInflater;import android.view.View;public class PagerTitleDemoActivity extends Activity { /** Called when the activity is first created. */ private ViewPager mViewPager; private PagerTitleStrip mPagerTitleStrip; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mViewPager = (ViewPager)findViewById(R.id.viewpager); mPagerTitleStrip = (PagerTitleStrip)findViewById(R.id.pagertitle); //将要分页显示的View装入数组中 LayoutInflater mLi = LayoutInflater.from(this); View view1 = mLi.inflate(R.layout.view1, null); View view2 = mLi.inflate(R.layout.view2, null); View view3 = mLi.inflate(R.layout.view3, null); //每个页面的Title数据 final ArrayListviews = new ArrayList (); views.add(view1); views.add(view2); views.add(view3); final ArrayList titles = new ArrayList (); titles.add("tab1"); titles.add("tab2"); titles.add("tab3"); //填充ViewPager的数据适配器 PagerAdapter mPagerAdapter = new PagerAdapter() { @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } @Override public int getCount() { return views.size(); } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager)container).removeView(views.get(position)); } @Override public CharSequence getPageTitle(int position) { return titles.get(position); } @Override public Object instantiateItem(View container, int position) { ((ViewPager)container).addView(views.get(position)); return views.get(position); } }; mViewPager.setAdapter(mPagerAdapter); }}
