ViewPager中使用自定义的ListView实例

这篇内容是上一篇的延续，因为在上一篇的测试ViewPager成功了，才能实现这一篇的和ListView合在一起使用

　　效果图如下：

　　

　　不愿意说理论，直接上代码

1.清单文件 activity_main.xml内容如下：

<?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/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
 
        <android.support.v4.view.PagerTabStrip
            android:id="@+id/pagerTabStrip"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
 
    </android.support.v4.view.ViewPager>
</LinearLayout>

2.主类代码MainActivity.java如下

package com.zyf.android.filemanage;
 
import java.io.File;
import java.util.ArrayList;
import com.zyf.android.adapter.MyListViewAdapter;
import com.zyf.android.adapter.MyPagerAdapter;
import com.zyf.androidfilemanage.R;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.View;
import android.widget.ListView;
 
public class MainActivity extends Activity {
 
    private ArrayList<View> views;
    private ArrayList<File> files;
 
    //private ArrayList<>
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
 
         setContentView(R.layout.activity_main);
 
        ViewPager viewPager = (ViewPager)findViewById(R.id.viewPager);
        views = new ArrayList<View>();
        View view0 =getLayoutInflater().inflate(R.layout.vp_phone, null);
        View view1 =getLayoutInflater().inflate(R.layout.vp_phone, null);
        View view2 =getLayoutInflater().inflate(R.layout.vp_phone, null);
        views.add(view0);
        views.add(view1);
        views.add(view2);
        viewPager.setAdapter(new MyPagerAdapter(views));
 
        files = new ArrayList<File>();
        files.add(new File("第一个文件"));
        files.add(new File("第二个文件"));
        files.add(new File("第三个文件"));
        files.add(new File("第四个文件"));
        ListView listView = (ListView)(view0.findViewById(R.id.listview_phone));
        listView.setVisibility(ListView.VISIBLE);
 
        listView.setAdapter(new MyListViewAdapter(files,getLayoutInflater()));
    }
}

3.ViewPager的适配器MyPagerAdapter.java代码如下:

package com.zyf.android.adapter;
 
import java.util.ArrayList;
 
import android.support.v4.view.PagerAdapter;
import android.view.View;
import android.view.ViewGroup;
 
public class MyPagerAdapter extends PagerAdapter {
 
    private ArrayList<View> views;
    private String[] pagerTabStrip={"手机","存储卡","云端"};
 
    public MyPagerAdapter(ArrayList<View> views) {
        // TODO Auto-generated constructor stub
        this.views =views;
    }
 
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return views == null ? 0 :views.size();
    }
 
    @Override
    public boolean isViewFromObject(View arg0, Object arg1) {
        // TODO Auto-generated method stub
        return arg0 == arg1;
    }
 
    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        // TODO Auto-generated method stub
        //super.destroyItem(container, position, object);
        container.removeView(views.get(position));
    }
 
    @Override
    public CharSequence getPageTitle(int position) {
        // TODO Auto-generated method stub
        return pagerTabStrip[position];
    }
 
    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        // TODO Auto-generated method stub
        View view = views.get(position);
 
        container.addView(view);
        return view;
    }
 
}

4.子view对应的ListView的vp_phone.xml代码如下

<?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="wrap_content"
    android:orientation="vertical" >
 
    <ListView
        android:id="@+id/listview_phone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
 
        >
    </ListView>
 
</LinearLayout>

4.ListView的适配器MyListViewAdapter.java代码如下:

package com.zyf.android.adapter;
 
import java.io.File;
import java.util.ArrayList;
 
import com.zyf.android.util.LogUtil;
import com.zyf.androidfilemanage.R;
 
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
 
public class MyListViewAdapter extends BaseAdapter{
 
    private ArrayList<File> files ;
    private LayoutInflater layoutInflater;
 
    public MyListViewAdapter(ArrayList<File> files, LayoutInflater layoutInflater) {
        super();
        this.files = files;
        this.layoutInflater =layoutInflater;
    }
 
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return files.size();
    }
 
    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return files.get(arg0);
    }
 
    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }
 
    @Override
    public View getView(int arg0, View arg1, ViewGroup arg2) {
 
        File file =files.get(arg0);
        String filename = file.getName();
        int icon = R.drawable.icon;
 
        HoldView holdView = null;
        if (arg1 == null){
            arg1 = layoutInflater.inflate(R.layout.item_file, null);
            holdView = new HoldView(arg1);
            arg1.setTag(holdView);
        }else{
            holdView = (HoldView)arg1.getTag();
        }
        holdView.getIv_con().setImageResource(icon);
        holdView.getTx_name().setText(filename);
 
        return arg1;
    }
 
    private class HoldView{
        ImageView iv_con;
        TextView tx_name;
        public HoldView(View view) {
            iv_con = (ImageView)view.findViewById(R.id.item_file_imageview);
            tx_name = (TextView)view.findViewById(R.id.item_file_name);
        }
        public ImageView getIv_con() {
            return iv_con;
        }
        public TextView getTx_name() {
            return tx_name;
        }
    }
}

6.ListView中的每个条目的资源文件item_file.xml如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >
 
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/item_file_imageview"
         />
 
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/item_file_imageview"
        android:id="@+id/item_file_name"
        />
</RelativeLayout>

总结，整体比较简单，就是ViewPager需要自己写适配器，同时ListView也是自己写的适配器，然后把两者整合到一起（就是从ViewPager中拿到ListView对应的view就可以了）
