ViewPager实现滑动

第一步：主布局activity_main.xml

<?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" >
    
    <android.support.v4.view.ViewPager
        android:id="@+id/main_mView"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1.5"
        android:background="@drawable/qq"
        ></android.support.v4.view.ViewPager>
    
</LinearLayout>

第二步：子布局main_activity_view1.xml

<?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" >
    
    <ImageView 
        android:id="@+id/main_view_imag1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@drawable/qq"
        />
    
</LinearLayout>

有多少子布局就创建几个，内容自己来定，这里案例只是展示，其余几个子布局都同上

第三步：java源码：MainActivity.java

package com.action;
import java.util.ArrayList;
import java.util.List;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.RelativeLayout;



public class MainActivity extends FragmentActivity {
    
    //主布局ViewPager;
        private ViewPager mViewPage;
        private List<View> lsview=new ArrayList<View>();
        private PagerAdapter mAdapter;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        
        //============ViewPager的创建===============================
                //主布局ViewPager获取
                
                mViewPage=(ViewPager)findViewById(R.id.main_mView);
                
                //ViewPager的事件监听
//                mViewPage.setOnPageChangeListener(this);
                
                //创建子布局选择对象
                LayoutInflater inflater=LayoutInflater.from(MainActivity.this);
                //通过子布局选择器获取需要的界面
                View view1=inflater.inflate(R.layout.main_activity_view1, null);
                View view2=inflater.inflate(R.layout.main_activity_view2, null);
                View view3=inflater.inflate(R.layout.main_activity_view3, null);
                View view4=inflater.inflate(R.layout.main_activity_view4, null);
                
                lsview.add(view1);
                lsview.add(view2);
                lsview.add(view3);
                lsview.add(view4);
                
                //创建ViewPager适配器
                mAdapter=new PagerAdapter() {
                    
                    @Override
                    public boolean isViewFromObject(View arg0, Object arg1) {
                        // TODO Auto-generated method stub
                        return arg0==arg1;
                    }
                    
                    @Override
                    public int getCount() {
                        // TODO Auto-generated method stub
                        return lsview.size();
                    }
                    
                    //创建这个适配器时，除了要强制重写以上两个方法外，还得重写一下两个方法
                    
                    //这个方法是摧毁view
                    @Override
                    public void destroyItem(View container, int position, Object object) {
                        // TODO Auto-generated method stub
                       // ((ViewPager) container).removeView(lsview.get(position));
                        //在移除View这个方法调用中，上面的方法已经过期不能使用，应当使用下面的方法
                        container.removeView((View) object);
                    }
                    
                    //这个方法是初始化view
                    @Override
                    public Object instantiateItem(ViewGroup container, int position) {
                        // TODO Auto-generated method stub

                        //需要先获取View
                        View view=lsview.get(position);
                        //然后将所有的view添加到ViewGroup这个存放view的容器中
                        container.addView(view);
                        //返回View
                        return view;
                        
                    }
                    
                };
                //给View添加适配器
                mViewPage.setAdapter(mAdapter);
                
                //=================================================================
    }

}

就这三步简单实现ViewPager滑动
