ViewPager，它是google SDk中自带的一个附加包的一个类， 可以使视图滑动。
步骤：
1、引入android-support-v4.jar包，在主布局里加入
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</android.support.v4.view.ViewPager>
2、加载切换内容
3、ViewPager加载适配器PagerAdapter
public class MainActivity extends Activity {
private ViewPager viewPager;
private ArrayList<View> pageview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//设置无标题栏
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
viewPager = (ViewPager) findViewById(R.id.viewPager);
//查找布局文件用LayoutInflater.inflate
LayoutInflater inflater =getLayoutInflater();
View view1 = inflater.inflate(R.layout.item01, null);
View view2 = inflater.inflate(R.layout.item02, null);
View view3 = inflater.inflate(R.layout.item03, null);
//将view装入数组
pageview =new ArrayList<View>();
pageview.add(view1);
pageview.add(view2);
pageview.add(view3);
//数据适配器
PagerAdapter mPagerAdapter = new PagerAdapter(){
@Override
//获取当前窗体界面数
public int getCount() {
// TODO Auto-generated method stub
return pageview.size();
}
@Override
//断是否由对象生成界面
public boolean isViewFromObject(View arg0, Object arg1) {
// TODO Auto-generated method stub
return arg0==arg1;
}
//是从ViewGroup中移出当前View
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView(pageview.get(arg1));
}
//返回一个对象，这个对象表明了PagerAdapter适配器选择哪个对象放在当前的ViewPager中
public Object instantiateItem(View arg0, int arg1){
((ViewPager)arg0).addView(pageview.get(arg1));
return pageview.get(arg1);
}
};
//绑定适配器
viewPager.setAdapter(mPagerAdapter);
}
}
