## 一、添加权限： ##

<uses-permission android:name="android.permission.READ_CONTACTS" />

--------------------

## 二、item.xml（创建ListView）： ##

<?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" >
    
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="60sp"
            android:orientation="horizontal" >
    
            <TextView
                android:id="@+id/tv_name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:text="1111"
                android:textSize="35sp" />
    
            <TextView
                android:id="@+id/tv_number"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                android:text="2222"
                android:textSize="25sp" />
        </LinearLayout>
    
    </LinearLayout>

--------------------

## 三、activity\_main.xml： ##

--------------------

## 四、ListViewAdapter.java(ListView的适配器): ##

package com.example.listviewshowlianxipeople;
    
    import java.util.List;
    
    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;
    
    @SuppressLint("InflateParams")
    public class ListViewAdapter extends BaseAdapter {
        
        List<String> names, phones;
        LayoutInflater inflater;
    
        @SuppressWarnings("static-access")
        public ListViewAdapter(Context context, List<String> names,
                List<String> phones) {
            inflater = inflater.from(context);
            this.names = names;
            this.phones = phones;
        }
    
        @Override
        public int getCount() {
            return names.size();
        }
    
        @Override
        public Object getItem(int position) {
            return position;
        }
    
        @Override
        public long getItemId(int position) {
            return position;
        }
    
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view;
            if (convertView == null) {
                view = inflater.inflate(R.layout.item, null);
                TextView tv_name = (TextView) view.findViewById(R.id.tv_name);
                TextView tv_phone = (TextView) view.findViewById(R.id.tv_number);
                tv_name.setText(names.get(position));
                tv_phone.setText(phones.get(position));
            } else {
                view = convertView;
            }
            return view;
        }
    
    }

--------------------

## 五、MainActivity.java: ##

package com.example.listviewshowlianxipeople;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import android.app.Activity;
    import android.database.Cursor;
    import android.os.Bundle;
    import android.provider.ContactsContract;
    import android.widget.ListView;
    
    public class MainActivity extends Activity {
        
        ListView lv;
        List<String> list_phone, list_name;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            lv = (ListView) findViewById(R.id.lv);
            list_name = new ArrayList<String>();
            list_phone = new ArrayList<String>();
            Cursor c = getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
                    null, null);
            //获取通讯录的信息
            startManagingCursor(c);
            int phoneIndex = 0, nameIndex = 0;
            if (c.getCount() > 0) {
                phoneIndex = c
                        .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                // 获取手机号码的列名
                nameIndex = c
                        .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
                // 获取用户名的列名
            }
            while (c.moveToNext()) {
                String phone = c.getString(phoneIndex);
                // 获取手机号码
                list_phone.add(phone);
                String name = c.getString(nameIndex);
                // 获取用户名
                list_name.add(name);
    
            }
    
            ListViewAdapter adapter = new ListViewAdapter(this, list_name,
                    list_phone);
            lv.setAdapter(adapter);
        }
    
    }
