步驟：
1谋竖、引入android-support-v4.jar包萄传，在mian_activity.xml布局里加入 如下代碼：
< ?xml version="1.0" encoding="utf-8"?>
< 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:orientation="vertical"
android:id="@+id/layout"
tools:context="com.zjq.viewpager.MainActivity">
< android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
< /RelativeLayout >
2瘸爽、其他幾個子布局都一樣 例如 item01 :
< ?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">
< ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/view1"
android:scaleType="centerCrop"
/>
</LinearLayout>
3方椎、編寫Java代碼:
public class MainActivity extends AppCompatActivity {
//查找布局文件用LayoutInflater.inflate
private LayoutInflater inflater;
//viewpager ID
private ViewPager viewpager;
//viewpager將view裝入數(shù)組
private ArrayList<View> pageview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpager = (ViewPager)findViewById(R.id.vp_FindFragment_pager);
// viewpager 查找布局文件用LayoutInflater.inflate
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);
View view4 = inflater.inflate(R.layout.item04, null);
//將分頁顯示的view裝入數(shù)組
pageview =new ArrayList<View>();
pageview.add(view1);
pageview.add(view2);
pageview.add(view3);
pageview.add(view4);
// viewpPager數(shù)據(jù)適配器
PagerAdapter mPagerAdapter = new PagerAdapter(){
@Override
//獲取當前窗體界面數(shù)
public int getCount() {
// TODO Auto-generated method stub
return pageview.size();
}
@Override
//斷是否由對象生成界面
public boolean isViewFromObject(View arg0, Object arg1) {
// TODO Auto-generated method stub
return arg0==arg1;
}
//是從ViewGroup中移出當前View
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView(pageview.get(arg1));
}
//返回一個對象，這個對象表明了PagerAdapter適配器選擇哪個對象放在當前的ViewPager中
public Object instantiateItem(View arg0, int arg1){
((ViewPager)arg0).addView(pageview.get(arg1));
return pageview.get(arg1);
}
};
//綁定適配器
viewpager.setAdapter(mPagerAdapter);
} }
