如何在Android中检索联系人姓名和电话号码

我正在尝试检索带有姓名和电话号码的联系人列表。我尝试以下代码：

 // Get a cursor over every contact.
    Cursor cursor = getContentResolver().query(People.CONTENT_URI, 
                                               null, null, null, null); 
    // Let the activity manage the cursor lifecycle.
    startManagingCursor(cursor);
    // Use the convenience properties to get the index of the columns
    int nameIdx = cursor.getColumnIndexOrThrow(People.NAME); 

    int phoneIdx = cursor. getColumnIndexOrThrow(People.NUMBER);
    String[] result = new String[cursor.getCount()];
    if (cursor.moveToFirst())
      do { 
        // Extract the name.
        String name = cursor.getString(nameIdx);
        // Extract the phone number.
        String phone = cursor.getString(phoneIdx);
        result[cursor.getPosition()] = name + "-" +" "+  phone;
      } while(cursor.moveToNext());

此代码应返回一个包含所有联系人姓名及其电话号码的数组，但此代码仅返回联系人姓名，电话号码中返回NULL

示例输出：

 John - null

不要像下面那样使用不推荐的API访问

        Cursor cursor = getContentResolver().
    query( Contacts.CONTENT_URI, 
            new String[]{Contacts.DISPLAY_NAME}, null, null,null);
    if(cursor!=null){
        while(cursor.moveToNext()){
            Cursor c = getContentResolver().query(Phone.CONTENT_URI, new String[]{Phone.NUMBER, Phone.TYPE}, 
                    " DISPLAY_NAME = '"+cursor.getString(cursor.getColumnIndex(Contacts.DISPLAY_NAME))+"'", null, null);
            while(c.moveToNext()){
                switch(c.getInt(c.getColumnIndex(Phone.TYPE))){
                case Phone.TYPE_MOBILE :
                case Phone.TYPE_HOME :
                case Phone.TYPE_WORK :
                case Phone.TYPE_OTHER :
                }
            }
        }
    }

地狱男孩是对的，Phone.xxx被腐蚀了。我使用查找uri这样做：

Uri look = Uri.withAppendedPath(Contacts.CONTENT_LOOKUP_URI, "23N9983726428fnwe");
Intent i = new Intent(Intent.ACTION_VIEW); 
i.setData(look);

在第一行中尝试Contacts.xxx，您将找到正确的解决方案。

查看从android mobile检索联系人的示例代码

    Cursor cursor = context.getContentResolver().query(
                ContactsContract.Contacts.CONTENT_URI, null, null, null, null);


String contactId = cursor.getString(cursor
                    .getColumnIndex(ContactsContract.Contacts._ID));

String name = cursor.getString(cursor                   .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

            Cursor phones = context.getContentResolver().query(
                    Phone.CONTENT_URI, null,
                    Phone.CONTACT_ID + " = " + contactId, null, null);
            while (phones.moveToNext()) {
                String number = phones.getString(phones
                        .getColumnIndex(Phone.NUMBER));
                int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
                switch (type) {
                case Phone.TYPE_HOME:                   
                     Log.i("TYPE_HOME", "" + number);
                    break;
                case Phone.TYPE_MOBILE:                 
                    Log.i("TYPE_MOBILE", "" + number);
                    break;
                case Phone.TYPE_WORK:                   
                     Log.i("TYPE_WORK", "" + number);
                    break;
                case Phone.TYPE_FAX_WORK:                   
                    Log.i("TYPE_FAX_WORK", "" + number);
                    break;
                case Phone.TYPE_FAX_HOME:
                    Log.i("TYPE_FAX_HOME", "" + number);
                    break;

                case Phone.TYPE_OTHER:
                    Log.i("TYPE_OTHER", "" + number);
                    break;
                }
            }
            phones.close();
cursor.close();

请尝试下面的代码

Cursor managedCursor = getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
 new String[] {Phone._ID, Phone.DISPLAY_NAME, Phone.NUMBER}, null, null,  Phone.DISPLAY_NAME + " ASC");

在Android清单中：

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

然后，您必须捕捉动作拾取联系人的结果：

@Override 
public void onActivityResult(int reqCode, int resultCode, Intent data){ 
    super.onActivityResult(reqCode, resultCode, data);

    switch(reqCode)
    {
       case (PICK_CONTACT):
         if (resultCode == Activity.RESULT_OK)
         {
             Uri contactData = data.getData();
             Cursor c = managedQuery(contactData, null, null, null, null);
              if (c.moveToFirst())
              {
                  String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                  String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

                  if (hasPhone.equalsIgnoreCase("1")) 
                  {
                      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                             ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
                      phones.moveToFirst();
                      String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                       Toast.makeText(getApplicationContext(), cNumber, Toast.LENGTH_SHORT).show();

                      String nameContact = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

                      editText.setText(nameContact+ " "+ cNumber);
                  }
             }
       }
    }
}

我现在无法模仿你的问题，但想问一下你得到的电话号码是多少？你是否在联系人数据库中检查了这些字段是否存在？然后你如何实际读取电话号码？当我执行

String phone=phone.NUMBER

时，如果一个联系人有多个号码，则返回

data1

，然后如何选择所需号码。我将如何使用

PICK\u contact

创建全局变量“PICK\u contact”：int PICK\u contact=10；谢谢你的回复。我试图按照你的方法，但我有一些问题。。。请检查这里：使用“选择意图”是获取联系人列表的一种更简单的方法！

@Override 
public void onActivityResult(int reqCode, int resultCode, Intent data){ 
    super.onActivityResult(reqCode, resultCode, data);

    switch(reqCode)
    {
       case (PICK_CONTACT):
         if (resultCode == Activity.RESULT_OK)
         {
             Uri contactData = data.getData();
             Cursor c = managedQuery(contactData, null, null, null, null);
              if (c.moveToFirst())
              {
                  String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                  String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

                  if (hasPhone.equalsIgnoreCase("1")) 
                  {
                      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                             ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
                      phones.moveToFirst();
                      String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                       Toast.makeText(getApplicationContext(), cNumber, Toast.LENGTH_SHORT).show();

                      String nameContact = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

                      editText.setText(nameContact+ " "+ cNumber);
                  }
