使用系统内置的ContentProvider获取非SIM卡的手机联系人

要使用系统的内置ContentProvider，首先得获取注册权限。

<uses-permission

android:name="android.permission.READ_CONTACTS">

</uses-permission>

给出权限注册源码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.syscp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="10" />
    <uses-permission
        android:name="android.permission.READ_CONTACTS">
    </uses-permission>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.syscp.Main"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

然后，就是直接在主Activity的界面里面显示出来。

主Activity代码如下

package com.example.syscp;

import android.net.Uri;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.provider.ContactsContract;
import android.provider.ContactsContract.Contacts;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.graphics.Color;
import android.view.Menu;
import android.widget.TextView;

public class Main extends Activity {
	// 查询ContentProvider时希望返回的列
	String[] colimns = { Contacts.DISPLAY_NAME, Contacts._ID,
	// People._ID,
	// People.NAME
	};
	Uri contactUri = Contacts.CONTENT_URI;
	// Uri contatUri=People.CONTENT_URI;
	TextView tv;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		tv = (TextView) findViewById(R.id.tv);
		String result = getQueryData();
		tv.setTextColor(Color.GREEN);
		tv.setTextSize(20.0f);
		tv.setText("ID\t姓名\t\t电话号码\n" + result);
	}

	// 获取联系人列表信息
	private String getQueryData() {
		// TODO Auto-generated method stub
		String result = "";
		// 获取ContentResolver对象
		ContentResolver resolver = getContentResolver();
		Cursor cursor = resolver.query(contactUri, colimns, null, null, null);
		// 获得ID、Name等字段的索引
		int idIndex = cursor.getColumnIndex(Contacts._ID);
		int nameIndex = cursor.getColumnIndex(Contacts.DISPLAY_NAME);

		String phoneNum = "";
		// 遍历cursor,提取数据
		for (cursor.moveToFirst(); (!cursor.isAfterLast()); cursor.moveToNext()) {
			result = result + cursor.getString(idIndex) + "\t";
			result = result + cursor.getString(nameIndex) + "\t";
			// 获取电话号码
			Cursor phone = resolver.query(
					ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
					ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "="
							+ cursor.getString(idIndex), null, null);
			while(phone.moveToNext()){
				int phoneIndex=phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
				String temp = phone.getString(phoneIndex);
				phoneNum="\t"+temp;
			}
			phone.close();
			result+=phoneNum+"\t\n";
		}
		cursor.close();
		return result;
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}
