Android跳转到通讯录获取用户名称和手机号码的实现思路

Uri uri = Uri.parse("content://contacts/people");Intent intent = new Intent(Intent.ACTION_PICK, uri);startActivityForResult(intent, 0);

/* * 跳转联系人列表的回调函数 * */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {  switch (requestCode){   case 0:    if(data==null)    {     return;    }    //处理返回的data,获取选择的联系人信息    Uri uri=data.getData();    String[] contacts=getPhoneContacts(uri);    et_name.setText(contacts[0]);    et_tele.setText(contacts[1]);    break;  }  super.onActivityResult(requestCode, resultCode, data); }

private String[] getPhoneContacts(Uri uri){  String[] contact=new String[2];  //得到ContentResolver对象  ContentResolver cr = getContentResolver();  //取得电话本中开始一项的光标  Cursor cursor=cr.query(uri,null,null,null,null);  if(cursor!=null)  {   cursor.moveToFirst();   //取得联系人姓名   int nameFieldColumnIndex=cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);   contact[0]=cursor.getString(nameFieldColumnIndex);   //取得电话号码   String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));   Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,     ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);   if(phone != null){    phone.moveToFirst();    contact[1] = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));   }   phone.close();   cursor.close();  }  else  {   return null;  }  return contact; }

<!--获取通讯录权限--><uses-permission Android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.READ_PHONE_STATE" />
