android:獲取手機號碼和姓名實現通訊錄

來自： http://blog.csdn.net/su20145104009/article/details/50826844

首先是運行結果

由于通訊錄在手機里是以數據庫貯存的 所以我們可以通過一個方法

context.getContentResolver().query(Phone.CONTENT_URI,
                null, null, null, null);

來獲得通訊錄 ,這個方法返回一個游標的數據類型，通過moveToNext()方法來獲取所有的手機號碼信息

當然讀取手機通訊錄需要權限 在adnroidManifest文件中聲明即可

由于我也實現了打電話的功能 所以也要聲明權限

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

布局文件

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/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</RelativeLayout>

listview的布局文件：item.xml，在這里我設置的頭像為默認的 當然也可以在手機數據庫中讀取聯系人的icon

<?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" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:padding="10dp"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/name"
        android:paddingTop="10dp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        android:text="name" />

    <TextView
        android:id="@+id/number"
        android:paddingTop="5dp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/name"
        android:layout_toRightOf="@id/image"
        android:text="number" />

</RelativeLayout>

自己封裝一個聯系人信息的類 有兩個變量

package com.example.getphonenumber;

public class PhoneInfo {
    private String name;
    private String number;
    public PhoneInfo(String name, String number) {
        this.name = name;
        this.number = number;
    }
    public String getName() {
        return name;
    }
    public String getNumber() {
        return number;
    }
}

讀取手機數據庫中的通訊錄

GetPhoneNumberFromMobile.class

package com.example.getphonenumber;

import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.database.Cursor;
import android.provider.ContactsContract.CommonDataKinds.Phone;

public class GetPhoneNumberFromMobile {
    private List<PhoneInfo> list;

    public List<PhoneInfo> getPhoneNumberFromMobile(Context context) {
        // TODO Auto-generated constructor stub
        list = new ArrayList<PhoneInfo>();
        Cursor cursor = context.getContentResolver().query(Phone.CONTENT_URI,
                null, null, null, null);
        //moveToNext方法返回的是一個boolean類型的數據 
        while (cursor.moveToNext()) {
            //讀取通訊錄的姓名
            String name = cursor.getString(cursor
                    .getColumnIndex(Phone.DISPLAY_NAME));
            //讀取通訊錄的號碼
            String number = cursor.getString(cursor
                    .getColumnIndex(Phone.NUMBER));
            PhoneInfo phoneInfo = new PhoneInfo(name, number);
            list.add(phoneInfo);
        }
        return list;
    }
}

自定義adapter

package com.example.getphonenumber;

import java.util.ArrayList;
import java.util.List;

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 MyAdapter extends BaseAdapter{
    private List<PhoneInfo> list;
    private Context context;

    public MyAdapter(List<PhoneInfo> list, Context context) {
        this.list = list;
        this.context = context;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        if(convertView==null){
            ViewHolder viewHolder=new ViewHolder();
            LayoutInflater inflater=LayoutInflater.from(context);
            convertView=inflater.inflate(R.layout.item, null);
            viewHolder.name=(TextView) convertView.findViewById(R.id.name);
            viewHolder.number=(TextView) convertView.findViewById(R.id.number);
            viewHolder.name.setText(list.get(position).getName());
            viewHolder.number.setText(list.get(position).getNumber());
        }
        return convertView;
    }
    public class ViewHolder{
        TextView name;
        TextView number;
    }
}

MainActivity中listview加載適配器 并為其添加點擊監聽事件

package com.example.getphonenumber;

import java.util.ArrayList;
import java.util.List;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity implements OnItemClickListener {
    private ListView lv;
    private MyAdapter adapter;
    private GetPhoneNumberFromMobile getPhoneNumberFromMobile;
    private List<PhoneInfo> list = new ArrayList<PhoneInfo>();

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        lv = (ListView) findViewById(R.id.listView1);
        getPhoneNumberFromMobile = new GetPhoneNumberFromMobile();
        list = getPhoneNumberFromMobile.getPhoneNumberFromMobile(this);
        adapter = new MyAdapter(list, this);
        lv.setAdapter(adapter);
        lv.setOnItemClickListener(this);
    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {
        // TODO Auto-generated method stub
        String number = list.get(position).getNumber();
        Intent intent = new Intent();
        intent.setAction("android.intent.action.CALL");
        intent.addCategory(Intent.CATEGORY_DEFAULT);
        intent.setData(Uri.parse("tel:"+number));
        startActivity(intent);
    }

}
