Android查看手机通讯录（ListView）

一、添加权限：

<uses-permission android:name="android.permission.READ_CONTACTS" /> 
<!-- 读取通讯录权限 -->

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：

<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" >
    <ListView
        android:id="@+id/lv"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </ListView>
</RelativeLayout>

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);
    }
}
