Android 获取手机联系人实例代码详解

我的风格，废话不多说了，直接给大家贴代码了。

具体代码如下所示：

package com.org.demo.demo;
import com.org.wangfeng.r;
import android.app.activity;
import android.content.intent;
import android.os.bundle;
import android.util.log;
import android.view.view;
import android.widget.button;
import android.widget.edittext;
public class getphoneactivity extends activity {
 private edittext edittext;
 private button button;
 @override
 protected void oncreate(bundle savedinstancestate) {
  // todo auto-generated method stub
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.getphoneactivity);
  edittext = (edittext) findviewbyid(r.id.et_getphone);
  button = (button) findviewbyid(r.id.bb_getphone);
  button.setonclicklistener(new view.onclicklistener() {
   @override
   public void onclick(view arg0) {
    // todo auto-generated method stub
    intent intent = new intent(getphoneactivity.this,
      contactactivity.class);
    startactivityforresult(intent, 1);
   }
  });
 }
 @override
 protected void onactivityresult(int requestcode, int resultcode, intent data) {
  // system.out.println("resultcode:" + resultcode);
  // system.out.println("requestcode:" + requestcode);
  log.d("jiejie", "被调用了");
  if (resultcode == activity.result_ok) {
   string phone = data.getstringextra("phone");
   log.d("jiejie", "_______________"+phone);
   phone = phone.replaceall("-", "").replaceall(" ", "");// 替换-和空格

   edittext.settext(phone);// 把电话号码设置给输入框
  }
  super.onactivityresult(requestcode, resultcode, data);
 }
}
package com.org.demo.demo;
import java.util.arraylist;
import java.util.hashmap;
import com.org.wangfeng.r;
import android.app.activity;
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.listview;
import android.widget.simpleadapter;
import android.widget.adapterview.onitemclicklistener;
import android.widget.textview;
public class contactactivity extends activity {
 private listview lvlist;
 private arraylist<hashmap<string, string>> readcontact;
 private textview back;
 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_contact);
  back =(textview)findviewbyid(r.id.back);
  back.setonclicklistener(new view.onclicklistener() {   
   @override
   public void onclick(view arg0) {
    // todo auto-generated method stub
    finish();
   }
  });
  lvlist = (listview) findviewbyid(r.id.lv_list);
  readcontact = readcontact();
  // system.out.println(readcontact);
  lvlist.setadapter(new simpleadapter(this, readcontact,
    r.layout.contact_list_item, new string[] { "name", "phone" },
    new int[] { r.id.tv_name, r.id.tv_phone }));
  lvlist.setonitemclicklistener(new onitemclicklistener() {
   @override
   public void onitemclick(adapterview<?> parent, view view,
     int position, long id) {
    string phone = readcontact.get(position).get("phone");// 读取当前item的电话号码
    intent intent = new intent();
    intent.putextra("phone", phone);
    setresult(activity.result_ok, intent);// 将数据放在intent中返回给上一个页面

    finish();
   }
  });
 }
 private arraylist<hashmap<string, string>> readcontact() {
  // 首先,从raw_contacts中读取联系人的id("contact_id")
  // 其次, 根据contact_id从data表中查询出相应的电话号码和联系人名称
  // 然后,根据mimetype来区分哪个是联系人,哪个是电话号码
  uri rawcontactsuri = uri
    .parse("content://com.android.contacts/raw_contacts");
  uri datauri = uri.parse("content://com.android.contacts/data");
  arraylist<hashmap<string, string>> list = new arraylist<hashmap<string, string>>();
  // 从raw_contacts中读取联系人的id("contact_id")
  cursor rawcontactscursor = getcontentresolver().query(rawcontactsuri,
    new string[] { "contact_id" }, null, null, null);
  if (rawcontactscursor != null) {
   while (rawcontactscursor.movetonext()) {
    string contactid = rawcontactscursor.getstring(0);
    // system.out.println(contactid);
    // 根据contact_id从data表中查询出相应的电话号码和联系人名称, 实际上查询的是视图view_data
    cursor datacursor = getcontentresolver().query(datauri,
      new string[] { "data1", "mimetype" }, "contact_id=?",
      new string[] { contactid }, null);
    if (datacursor != null) {
     hashmap<string, string> map = new hashmap<string, string>();
     while (datacursor.movetonext()) {
      string data1 = datacursor.getstring(0);
      string mimetype = datacursor.getstring(1);
      // system.out.println(contactid + ";" + data1 + ";"
      // + mimetype);
      if ("vnd.android.cursor.item/phone_v2".equals(mimetype)) {
       map.put("phone", data1);
      } else if ("vnd.android.cursor.item/name"
        .equals(mimetype)) {
       map.put("name", data1);
      }
     }
     list.add(map);
     datacursor.close();
    }
   }
   rawcontactscursor.close();
  }
  return list;
 }
}

本段代码到此结束，代码比较简单，并附有注释，希望对大家学习android获取手机联系人相关知识有所帮助。
