Android ContentProvider查看/读取手机联系人实例_Android

看到某些app里面有读取联系人的功能，然后自己尝试了一下。发现这个挺简单的。然后自己就做了一个demo给大家，希望借这个demo可以让大家学习一下怎么实现读取手机联系人。

这里我用了两种方法去读取：第一张图片是跳转到系统自带的联系人界面，第二种就是直接去读取让后绑上来显示在主页面。话不多说直接上代码。

记得在androidmanifest.xml 记得加入这两句，不然就读取不到联系人。

<uses-permission android:name="android.permission.read_contacts" />
<uses-permission android:name="android.permission.write_contacts" />

       //加载listview
       listview listview=(listview) findviewbyid(r.id.mian_list);
       listview.setadapter(adapter);
      }
    });


    //跳转系统的联系人界面
    findviewbyid(r.id.main_btn_sys).setonclicklistener(new onclicklistener() {

      @override

      }
    });
  }

  @override

  // todo auto-generated method stub
  super.onactivityresult(requestcode, resultcode, data);
    uri uri=data.getdata();
    cursor cursor = getcontentresolver()
        .query(uri, null, null, null, null);
    while(cursor.movetonext()){
      string name=cursor.getstring(cursor.getcolumnindexorthrow(contacts.phones.name));
      string number=cursor.getstring(cursor.getcolumnindexorthrow(contacts.phones.number));
      textview textview=(textview) findviewbyid(r.id.mian_lists);
      textview.settext("名字："+name+"  电话号码："+number);
    }
  }



}

这是主界面
