【中文标题】如何从设备获取联系电话？【英文标题】：How do I get contact numbers from device? 【发布时间】：2016-12-12 16:16:32 【问题描述】：我想在ListView 中显示联系电话。它运行良好。但是我想在从设备读取联系人时设置条件。条件是
if number digit <10 --don't add into list-.
else if(number is started from 0 then replace with 91)--Add to list.
else ifnumber is start from + then remove it --add to list。
else其他都是直接加入列表。
这是我的代码：
public class ReferFriend extends AppCompatActivity
ArrayList<SelectUser> selectUsers;
List<SelectUser> temp;
ListView listView;
Cursor phones, email;
ContentResolver resolver;
SearchView search;
SelectUserAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.refer_friend);
selectUsers = new ArrayList<SelectUser>();
resolver = this.getContentResolver();
listView = (ListView) findViewById(R.id.contacts_list);
phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
LoadContact loadContact = new LoadContact();
loadContact.execute();
// Load data on background
class LoadContact extends AsyncTask<Void, Void, Void>
@Override
protected void onPreExecute()
super.onPreExecute();
@Override
protected Void doInBackground(Void... voids)
// Get Contact list from Phone
if (phones != null)
Log.e("count", "" + phones.getCount());
if (phones.getCount() == 0)
Toast.makeText(ReferFriend.this, "No contacts in your contact list.", Toast.LENGTH_LONG).show();
while (phones.moveToNext())
Bitmap bit_thumb = null;
String id = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String image_thumb = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI));
try
if (image_thumb != null)
bit_thumb = MediaStore.Images.Media.getBitmap(resolver, Uri.parse(image_thumb));
else
Log.e("No Image Thumb", "--------------");
catch (IOException e)
e.printStackTrace();
SelectUser selectUser = new SelectUser();
selectUser.setThumb(bit_thumb);
selectUser.setContactName(name);
selectUser.setPhone(phoneNumber);
selectUser.setContactEmail(id);
selectUser.setCheckedBox(false);
selectUsers.add(selectUser);
else
Log.e("Cursor close 1", "----------------");
//phones.close();
return null;
@Override
protected void onPostExecute(Void aVoid)
super.onPostExecute(aVoid);
adapter = new SelectUserAdapter(selectUsers, ReferFriend.this);
listView.setAdapter(adapter);
// Select item on listclick
listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l)

【问题讨论】：
这个问题能回答你的问题吗？ ***.com/questions/15243278/… 谢谢你解决它.. 如果上面的链接对你有用，请接受它作为重复。 【参考方案1】：在添加联系人记录验证功能之前，它将验证您所有需要的条件。如果验证成功，则该函数将返回 true，否则返回 false。如果返回 true，则将该联系人添加到 selectUser 对象，否则不要添加。
【讨论】：
我已经添加了一些条件，但是它们没有以正确的方式编写，代码在我的帖子中被注释块。请检查一下并给我解决方案【参考方案2】：SelectUser selectUser = new SelectUser();
selectUser.setThumb(bit_thumb);
selectUser.setContactName(name);
selectUser.setPhone(phoneNumber);
selectUser.setContactEmail(id);
selectUser.setCheckedBox(false);
//object preparation
Boolean flag = prepareObject(selectUser);
if(flag)
//add valid object to arraylist
selectUsers.add(selectUser);
else
//invalid contact details
//method to validate and update object
public Boolean prepareObject(SelectUser obj)
if(obj.getPhone.lenght < 10)
//dont add to list
else
String temp = obj.getPhone.charAt(0);
if(temp == "0")
//replace it with 91 and update object
return true
else if(temp == "+")
//remove it and update object
return true
else
//add to object
return true
return false;
我已经为您的问题写下了逻辑代码。只需对其进行必要的更改，它肯定会起作用。
您直接将对象添加到 arraylist 而不检查您的条件。 您在适配器上编写错误的条件，apdater 只会从 arraylist 填充数据。如果您将有效数据放入 arraylist，则无需在适配器上设置条件。
