android:獲取手機號碼和姓名實現通訊錄

首先是運行結果

由於通訊錄在手機裡是以數據庫貯存的 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

由於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"></uses-permission></uses-permission>

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，在這裡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

<!--{cke_protected}{C}%3C!%2D%2D%3Fxml%20version%3D%221.0%22%20encoding%3D%22utf-8%22%3F%2D%2D%3E-->
<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">

</textview></textview></imageview></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 list;

	public List getPhoneNumberFromMobile(Context context) {
		// TODO Auto-generated constructor stub
		list = new ArrayList();
		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 list;
	private Context context;
	
	public MyAdapter(List 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 並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 list = new ArrayList();

	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);
	}

}
