在Android应用中从联系人列表中选择一个号码和名称

Question

我想从我的联系人列表中选择一个联系人.我读了很多解决方案和研究几周,但所有文章都没有正常工作.一些代码如下:

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);

//并且在activityresult中:

if (resultCode == Activity.RESULT_OK) {
            Uri contactData = data.getData();
            Cursor c =  managedQuery(contactData, null, null, null, null);
            if (c.moveToFirst()) {
              String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
              tv1.setText(name);
            }
          }

或者此代码用于获取所有联系人但我不能拥有联系人数量:

String[] contacts = new String[] {People.NAME, People.NUMBER};       
Uri contentUri = People.CONTENT_URI;        
Cursor cursor = managedQuery(contentUri, contacts, null, null, null);                 
String textContacts = "";                 
if (cursor.moveToFirst()) {         
    String myname = null;         
    String mynumber = null;         
    do {          
        textContacts = textContacts + cursor.getString(cursor.getColumnIndex(People.NAME)) + " : " + cursor.getString(cursor.getColumnIndex(People.NUMBER)) + "\n";         
    } while (cursor.moveToNext()); 
tv1.setText(textContacts);
}

尝试以下代码,它将帮助您:

  // You need below permission to read contacts
  <uses-permission android:name="android.permission.READ_CONTACTS"/>

  // Declare
  static final int PICK_CONTACT=1;

  Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
  startActivityForResult(intent, PICK_CONTACT);

  //code 
  @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();
              cNumber = phones.getString(phones.getColumnIndex("data1"));
             System.out.println("number is:"+cNumber);
           }
         String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));


     }
   }
   break;
 }
 }

使用Intent.ACTION_PICK访问电话联系人.代码为

Uri uri = Uri.parse("content://contacts");
Intent intent = new Intent(Intent.ACTION_PICK, uri);
intent.setType(Phone.CONTENT_TYPE);
startActivityForResult(intent, REQUEST_CODE);

哪里

private static final int REQUEST_CODE = 1;

并使用onActivityResult()方法访问所选联系人.代码为

@Override
    protected void onActivityResult(int requestCode, int resultCode,
            Intent intent) {
        if (requestCode == REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                Uri uri = intent.getData();
                String[] projection = { Phone.NUMBER, Phone.DISPLAY_NAME };

                Cursor cursor = getContentResolver().query(uri, projection,
                        null, null, null);
                cursor.moveToFirst();

                int numberColumnIndex = cursor.getColumnIndex(Phone.NUMBER);
                String number = cursor.getString(numberColumnIndex);

                int nameColumnIndex = cursor.getColumnIndex(Phone.DISPLAY_NAME);
                String name = cursor.getString(nameColumnIndex);

                Log.d(TAG, "ZZZ number : " + number +" , name : "+name);

            }
        }
    };

添加将联系人数据读取到应用程序清单的权限.

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

Intent.Action_Pick在您的活动中使用,如下所示

Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
        startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);

然后覆盖 onActivityResult()

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // check whether the result is ok
        if (resultCode == RESULT_OK) {
            // Check for the request code, we might be usign multiple startActivityForReslut
            switch (requestCode) {
            case RESULT_PICK_CONTACT:
               Cursor cursor = null;
        try {
            String phoneNo = null ;
            String name = null;           
            Uri uri = data.getData();            
            cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();           
            int  phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
            phoneNo = cursor.getString(phoneIndex); 

            textView2.setText(phoneNo);
        } catch (Exception e) {
            e.printStackTrace();
        }
                break;
            }
        } else {
            Log.e("MainActivity", "Failed to pick contact");
        }
    }

这将检查出来
