Android獲取全部聯系人信息的例子

先定義一個顯示條目的xml布局文件

package com.wzw.test;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.view.Menu;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class SelectContactActivity extends Activity {

	private ListView list_select_contact;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_select_contact);
		list_select_contact=(ListView) findViewById(R.id.list_select_contact);
		List> data = getContactInfo();
		list_select_contact.setAdapter(new SimpleAdapter(this, data	, R.layout.contact_item, new String[] { "name", "phone" }, new int[] { R.id.tv_name, R.id.tv_phone}));
	}
	
	/**
	 * 獲取所有聯系人信息
	 * @return
	 */
	private List> getContactInfo() {


		//存放所有的聯系人
		List> list  = new ArrayList>();

		// 得到一個內容解析器
		ContentResolver resolver = getContentResolver();
		// raw_contacts uri
		Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
		Uri uriData = Uri.parse("content://com.android.contacts/data");

		Cursor cursor = resolver.query(uri, new String[] { "contact_id" },
				null, null, null);

		while (cursor.moveToNext()) {
			String contact_id = cursor.getString(0);
			
			if (contact_id != null) {
