1.首先你的先在布局文件中写两个ListView
上布局文件代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- rightView -->

    <LinearLayout
        android:id="@+id/ourcompany_leftview_layout"
        android:layout_width="180dp"
        android:layout_height="fill_parent"
        android:layout_alignParentRight="true"
        android:orientation="vertical" >

        <ListView
            android:id="@+id/job_fair_title_list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="88dip"
            android:cacheColorHint="@android:color/transparent"
            android:choiceMode="singleChoice"
            android:divider="@null" >
        </ListView>
    </LinearLayout>

    <RelativeLayout
        android:id="@+id/ourcompany_back_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:paddingBottom="20dp"
        android:paddingTop="20dp" >

        <TextView
            android:id="@+id/ourcompany_title_text_tv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:text="双listview共存"
            android:textColor="#ffffff"
            android:textSize="25sp" />
    </RelativeLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/ourcompany_back_layout"
        android:layout_toLeftOf="@+id/ourcompany_leftview_layout"
        android:orientation="vertical" >

        <ListView
            android:id="@+id/job_fair_content_list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:cacheColorHint="@android:color/transparent"
            android:choiceMode="singleChoice"
            android:divider="@null" />
    </LinearLayout>

</RelativeLayout>

MainActivity的代码

package com.example.sockettest;

import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity {

    RightListViewAdapter mXlist_adapter;
    LiftListViewAdapter mJob_date_listadapter;
    private ListView right_list;
    private ListView left_list;
    private ArrayList<String> mLeftList = new ArrayList<String>();
    private ArrayList<String> mRightList = new ArrayList<String>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
        initXlistAdapter();

    }

    private void init() {
        right_list = (ListView) findViewById(R.id.job_fair_title_list);
        left_list = (ListView) findViewById(R.id.job_fair_content_list);

    }

    private void initXlistAdapter() {
        for (int i = 0; i < 10; i++) {
            mLeftList.add("left_list" + i);
            mRightList.add("Right" + i);
        }
        mXlist_adapter = new RightListViewAdapter(getApplicationContext(),
                mLeftList);
        left_list.setAdapter(mXlist_adapter);
        left_list.setOnItemClickListener(new onXlistclic());
        mJob_date_listadapter = new LiftListViewAdapter(
                getApplicationContext(), mRightList);
        right_list.setAdapter(mJob_date_listadapter);
        right_list.setOnItemClickListener(new ontitleclic());

    }

    class onXlistclic implements OnItemClickListener {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "this is left list" + arg2,
                    Toast.LENGTH_LONG).show();

        }
    }

    class ontitleclic implements OnItemClickListener {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(),
                    "this is right list" + arg2, Toast.LENGTH_LONG).show();

        }
    }
}

左边ListView的适配器

package com.example.sockettest;

import java.util.ArrayList;

import android.annotation.SuppressLint;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class LiftListViewAdapter extends BaseAdapter {
    private LayoutInflater inflater;
    private Context mContext;
    private ArrayList<String> mZixunList = new ArrayList<String>();
    private int mIndex;

    public LiftListViewAdapter(Context context, ArrayList<String> zixunList) {
        this.mContext = context;
        this.mZixunList = zixunList;
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }

    @Override
    public int getCount() {
        return mZixunList.size();
    }

    @Override
    public Object getItem(int position) {
        return mZixunList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @SuppressLint("ResourceAsColor")
    @Override
    public View getView(final int position, View view, ViewGroup parent) {
        ProductTextView itemview = null;
        if (view == null) {
            itemview = new ProductTextView();
            view = inflater.inflate(R.layout.job_jair_xlist_content_list_item,
                    null);
            itemview.job_workname = (TextView) view
                    .findViewById(R.id.job_jair_xlist_work_name);
            view.setTag(itemview);
        } else {
            itemview = (ProductTextView) view.getTag();
        }
        itemview.job_workname.setText(mZixunList.get(position));
        return view;
    }

    private class ProductTextView {
        TextView job_workname;

    }
}

有边ListView的适配器

package com.example.sockettest;

import java.util.ArrayList;

import android.annotation.SuppressLint;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class RightListViewAdapter extends BaseAdapter {
    private LayoutInflater inflater;
    private Context mContext;
    private ArrayList<String> mZixunList = new ArrayList<String>();
    private int mIndex;

    public RightListViewAdapter(Context context,
            ArrayList<String> zixunList) {
        this.mContext = context;
        this.mZixunList = zixunList;
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    }

    @Override
    public int getCount() {
        return mZixunList.size();
    }

    @Override
    public Object getItem(int position) {
        return mZixunList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @SuppressLint("ResourceAsColor")
    @Override
    public View getView(final int position, View view, ViewGroup parent) {
        ProductTextView itemview = null;
        if (view == null) {
            itemview = new ProductTextView();
            view = inflater.inflate(R.layout.job_jair_xlist_content_list_item,
                    null);
            itemview.job_workname = (TextView) view
                    .findViewById(R.id.job_jair_xlist_work_name);
            view.setTag(itemview);
        } else {
            itemview = (ProductTextView) view.getTag();
        }

        itemview.job_workname.setText(mZixunList.get(position));
        return view;
    }

    private class ProductTextView {
        TextView job_workname;
    }
}

到此结束，本人是安卓界的菜鸟，第一次写博客，以后还会写更多更优秀的博客，以这次全部粘代码形势勉励自己，每天进步一点点！！
