获取手机通讯录

android基本操作--获取手机通讯录。本文简要讲解怎样获取android手机通讯录。并通过List把通讯录显示出来。

 

主程序如下：

package com.xiaochun91103;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.app.ListActivity;import android.database.Cursor;import android.os.Bundle;import android.provider.Contacts.People;import android.provider.Contacts.Phones;import android.provider.ContactsContract.Contacts;import android.widget.SimpleAdapter;public class GetContactTest extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); SimpleAdapter adapter = new SimpleAdapter(GetContactTest.this,getData(),R.layout.item,new String[]{ "name","number" },new int[]{ R.id.name,R.id.number }); setListAdapter(adapter); }private ArrayList<? extends Map<String, String>> getData() {// TODO Auto-generated method stubArrayList<Map<String, String>> list = new ArrayList<Map<String, String>>();String[] columns = new String[] {Phones.NAME,Phones.NUMBER};Cursor cursor = GetContactTest.this.getContentResolver().query(Phones.CONTENT_URI, columns, null, null, People.DEFAULT_SORT_ORDER);while(cursor.moveToNext()) {Map<String, String> map = new HashMap<String, String>();map.put("name", cursor.getString(0));map.put("number", cursor.getString(1));list.add(map);}return list;}}

 

布局文件如下：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"><TextView android:id="@+id/name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:textSize="20dip"/><TextView android:id="@+id/number" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/name"/></RelativeLayout>
