Android读取选择联系人的模版代码实现

1、创建SelectContactActivity类，在AndroidManifest.xml添加类

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

import android.app.Activity;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class SelectContactActivity extends Activity {

	private ListView lv_select_contact;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_select_contact);
		lv_select_contact = (ListView) findViewById(R.id.lv_select_contact);
		final List<Map<String,String>> data = getContactInfo();
		lv_select_contact.setAdapter(new SimpleAdapter(this, data, R.layout.contact_item_view,
				new String[]{"name","phone"}, new int[]{R.id.tv_name,R.id.tv_phone}));
		lv_select_contact.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view, int position,
					long id) {
				String phone = data.get(position).get("phone");
				Intent data = new Intent();
				data.putExtra("phone", phone);
				setResult(0, data);
				//关闭掉当前的页面
				finish();
			}
			
		});
	}
	
	/**
	 * 读取手机里面的联系人
	 * @return
	 */
	private List<Map<String, String>> getContactInfo() {
		List<Map<String, String>> list = new ArrayList<Map<String,String>>();
		
		//得到一个内容解析器
		ContentResolver resolver = getContentResolver();
		//raw_contact 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){
				//具体的某一个联系人
				Map<String, String> map =new HashMap<String, String>();
				Cursor dataCursor = resolver.query(uriData, new String[]{"data1","mimetype"}, "contact_id=?", new String[]{contact_id}, null);
				while(dataCursor.moveToNext()){
					String data1 = dataCursor.getString(0);
					String mimetype = dataCursor.getString(1);
					System.out.println("data1=="+data1+"mimetype=="+mimetype);
					
					if("vnd.android.cursor.item/name".equals(mimetype)){
						//联系人的姓名
						map.put("name", data1);
					}else if("vnd.android.cursor.item/phone_v2".equals(mimetype)){
						//联系人的电话号码
						map.put("phone", data1);
					}
				}
				list.add(map);
				dataCursor.close();
			}
		}
		cursor.close();
		return list;
	}
}

2、读取联系人需要获得权限

添加权限：<uses-permission android:name="android.permission.READ_CONTACTS"/>

3、前面java需要引入相关layout，模版如下注意姓名号码id：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:background="#8866ff00"
        android:gravity="center"
        android:textColor="#000000"
        android:textSize="20sp"
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="55dip"
        android:text="选择联系人"/>
  
    <ListView 
        android:verticalSpacing="10dip"
        android:layout_marginTop="15dip"
        android:numColumns="3"
        android:id="@+id/lv_select_contact"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</LinearLayout>

4、实现选择联系人的点击事件

xml的Button中 android:onClick="selectContact" ，注意返回startActivityForresult()方法

	 * 选择联系人的点击事件
	 */
	public void selectContact(View view){
		Intent intent = new Intent(this,SelectContactActivity.class);
		startActivityForResult(intent, 0);
	}

5、然后将点击的联系人投射到号码输入框

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		// TODO Auto-generated method stub
		super.onActivityResult(requestCode, resultCode, data);
		
		if(data == null){
			return ;
		}
		//et_setup3_phone是输入框的id
		String phone = data.getStringExtra("phone").replace("-", "");
		et_setup3_phone.setText(phone);
	}

6、最后说下注意点

在获取完号码后，整个流程就结束了，在再次引用号码时最好toString().trim()操作，然后如果有必要可以判空和保存，保存要注意commit()。
