【中文标题】Android从联系人列表中获取电话号码【英文标题】:Android get phone number from contact list 【发布时间】:2017-04-13 05:03:42 【问题描述】:我有这些代码,它们基本上使用 ListView 来显示联系人列表中的姓名,我想在单击每个姓名时获取他们的电话号码:
final ContentResolver cr = getContentResolver();
final Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] ContactsContract.Contacts.DISPLAY_NAME, new int[]R.id.TVRow, 0);
myPhoneList.setAdapter(myCursorAdapter);
myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
c.moveToPosition(position);
Toast.makeText(getApplicationContext(), c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), Toast.LENGTH_SHORT).show();
);
在onItemClick
方法中
GetColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
返回 -1,因此我无法使用此方法获取电话号码。
我还尝试打印出光标 c
的所有列,它返回 34 列,但似乎与电话号码相关的唯一列是 HasPhoneNumber
。
那么问题出在哪里,我该如何解决?谢谢!
更新版本,其中 String
数组传递给构造 myCursorAdapter
发生变化:
final ContentResolver cr = getContentResolver();
final Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] ContactsContract.CommonDataKinds.Phone.NUMBER, new int[]R.id.TVRow, 0);
myPhoneList.setAdapter(myCursorAdapter);
myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
c.moveToPosition(position);
Toast.makeText(getApplicationContext(), c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), Toast.LENGTH_SHORT).show();
);
我想更新后的代码将在 ListView 中显示电话号码,但我收到一条错误消息“列 'data1' 不存在”。
【问题讨论】:
【参考方案1】:首先在 androidManifest.xml 中添加这一行以获得用户的许可。
<uses-permission android:name="android.permission.READ_CONTACTS"/>
实现联系按钮
phoneContactsButtton.setOnClickListener(new OnClickListener()
@Override
public void onClick(View view)
// The below two line is needed to open the contact list of mobile
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(contactPickerIntent,1);
);
你必须重写 onActivityResult() 它将被写入 onCreate() 方法的外部 类似这个
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode)
case 1 :
if (resultCode == Activity.RESULT_OK)
Uri contactData = data.getData();
Cursor cur = getContentResolver().query(contactData, null, null, null, null);
if (cur.getCount() > 0) // thats mean some resutl has been found
if(cur.moveToNext())
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.e("Names", name);
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
while (phones.moveToNext())
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.e("Number", phoneNumber);
phones.close();
cur.close();
break;

【参考方案2】:您可以使用以下代码在 Recyclerview 中获取联系人列表;
List<ContactVO> contactVOList = new ArrayList();
String[] projection = new String[]ContactsContract.Contacts._ID, ContactsContract.Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.PHOTO_URI;
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, null, null,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
List<ContactVO> userList = new ArrayList<>();
String lastPhoneName = " ";
if (phones.getCount() > 0)
while (phones.moveToNext())
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String contactId = phones.getString(phones.getColumnIndex(ContactsContract.Contacts._ID));
String photoUri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
if (!name.equalsIgnoreCase(lastPhoneName))
lastPhoneName = name;
ContactVO user = new ContactVO();
user.setContactName(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
user.setContactNumber(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
userList.add(user);
Log.d("getContactsList", name + "---" + phoneNumber + " -- " + contactId + " -- " + photoUri);
phones.close();
AllContactsAdapter contactAdapter = new AllContactsAdapter(userList, getApplicationContext());
rvContacts.setLayoutManager(new LinearLayoutManager(PhoneDirectoryActivity.this));
rvContacts.setAdapter(contactAdapter);
ContactVO
类文件下面;
public class ContactVO
private String ContactImage;
private String ContactName;
private String ContactNumber;
public String getContactImage()
return ContactImage;
public void setContactImage(String contactImage)
this.ContactImage = ContactImage;
public String getContactName()
return ContactName;
public void setContactName(String contactName)
ContactName = contactName;
public String getContactNumber()
return ContactNumber;
public void setContactNumber(String contactNumber)
ContactNumber = contactNumber;
以下是AllContactsAdapter
文件
public class AllContactsAdapter extends RecyclerView.Adapter<AllContactsAdapter.ContactViewHolder>
private List<ContactVO> contactVOList;
private Context mContext;
private SparseBooleanArray itemStateArray = new SparseBooleanArray();
public AllContactsAdapter(List<ContactVO> contactVOList, Context mContext)
this.contactVOList = contactVOList;
this.mContext = mContext;
@Override
public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
View view = LayoutInflater.from(mContext).inflate(R.layout.single_contact_view, null);
ContactViewHolder contactViewHolder = new ContactViewHolder(view);
return contactViewHolder;
@Override
public void onBindViewHolder(ContactViewHolder holder, int position)
ContactVO contactVO = contactVOList.get(position);
holder.tvContactName.setText(contactVO.getContactName());
holder.tvPhoneNumber.setText(contactVO.getContactNumber());
holder.bind(position);
holder.cbContact.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)
int adapterPosition = position;
if (!itemStateArray.get(adapterPosition, false))
holder.cbContact.setChecked(true);
contactsList.add(holder.tvPhoneNumber.getText().toString());
itemStateArray.put(adapterPosition, true);
else
holder.cbContact.setChecked(false);
itemStateArray.put(adapterPosition, false);
contactsList.remove(holder.tvPhoneNumber.getText().toString());
);
@Override
public int getItemCount()
return contactVOList.size();
public class ContactViewHolder extends RecyclerView.ViewHolder
ImageView ivContactImage;
TextView tvContactName;
TextView tvPhoneNumber;
CheckBox cbContact;
public ContactViewHolder(View itemView)
super(itemView);
ivContactImage = itemView.findViewById(R.id.ivContactImage);
tvContactName = itemView.findViewById(R.id.tvContactName);
tvPhoneNumber = itemView.findViewById(R.id.tvPhoneNumber);
cbContact = itemView.findViewById(R.id.cbContact);
void bind(int arg1)
// use the sparse boolean array to check
if (!itemStateArray.get(arg1, false))
cbContact.setChecked(false);
else
cbContact.setChecked(true);

【参考方案3】:ContactsContract
Android API 将联系人数据(例如电话号码)存储在Data
表中,而不是Contacts
表中。
仔细阅读:https://developer.android.com/reference/android/provider/ContactsContract.html。
更新 - 这是您的代码的固定版本(未经测试):
final ContentResolver cr = getContentResolver();
String[] projection = new String[] Contacts.DISPLAY_NAME, Phone.NUMBER;
final Cursor c = cr.query(Data.CONTENT_URI, projection, null, null, null);
myCursorAdapter = new SimpleCursorAdapter(this, R.layout.list_item, c, new String[] Phone.NUMBER, new int[]R.id.TVRow, 0);
myPhoneList.setAdapter(myCursorAdapter);
myPhoneList.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
c.moveToPosition(position);
Toast.makeText(getApplicationContext(), c.getString(1), Toast.LENGTH_SHORT).show();
);
【讨论】:
【参考方案4】:它返回 -1 因为您没有从 DB 请求列 ContactsContract.CommonDataKinds.Phone.NUMBER
:
new String[] ContactsContract.Contacts.DISPLAY_NAME
ContactsContract.Contacts.DISPLAY_NAME
是您请求的唯一字段。
为了能够获取电话号码,您首先需要将其包含在要从 DB 获取的列列表中:
新字符串[] ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER
现在您必须覆盖适配器的getView
,以便将名称设置到列表行的 textView 中。之后,您的 onItemClick
将按预期工作
【讨论】:
我只尝试了 String[] 中的 ContactsContract.CommonDataKinds.Phone.NUMBER 并得到错误:列 'data1' 不存在。我想既然我已经在查询中包含了所有字段,那么光标应该包含关于电话号码的字段,适配器应该不是原因? @T.Yu,我不明白你改变了什么,现在有什么问题 我将 new String[] ContactsContract.Contacts.DISPLAY_NAME 更改为 new String[] ContactsContract.CommonDataKinds.Phone.NUMBER 我想它会在 ListView 中显示电话号码,但我得到了错误提示“列 'data1' 不存在”。 @T.Yu,好的,ContactsContract.CommonDataKinds.Phone.NUMBER
可能是错误的列名。让我检查一下
应该是。到目前为止,我访问过的几乎所有互联网上的相关帖子都使用了这个专栏。【参考方案5】:
此答案只是上述答案的一个小更新。它可能对某人有所帮助。
StarActivityForResult 已弃用。所以我们可以在 Kotlin 中使用下面的模型。
在清单中:
<uses-permission android:name="android.permission.READ_CONTACTS" />
请同时实现运行时权限。我的代码中还没有完成。
用于处理结果的以下行:
private val openContacts = registerForActivityResult(ActivityResultContracts.PickContact())
val contactData: Uri = it
val phone: Cursor? = contentResolver.query(contactData!!, null, null, null, null)
if (phone!!.moveToFirst())
val contactName: String = phone.getString(phone.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
// To get number - runtime permission is mandatory.
val id: String = phone.getString(phone.getColumnIndex(ContactsContract.Contacts._ID))
if (phone.getString(phone.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)).toInt() > 0)
val phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id, null, null)
while (phones!!.moveToNext())
val phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
Log.d("## Number", phoneNumber)
phones!!.close()
Log.d("## Contact Name", contactName)
打开联系人:
button.setOnClickListener
openContacts.launch(null)
