連絡先の読み取りと書き込みのアクセス許可

Question

私は連絡先を読むことができましたが、私は連絡先を書くだけでなく読みたいと思います。誰も私がこれらの2つのタスクを行うことができる方法をアドバイスしてもらえますか？ エラーメッセージ。

READ_CONTACTSについては、私のコードを参照してください。WRITE_CONTACTSにも展開したいと思います。

 // Called when the user is performing an action which requires the app to read the 
    // user's contacts 
    public void getPermissionToReadUserContacts() { 
     // 1) Use the support library version ContextCompat.checkSelfPermission(...) to avoid 
     // checking the build version since Context.checkSelfPermission(...) is only available 
     // in Marshmallow 
     // 2) Always check for permission (even if permission has already been granted) 
     // since the user can revoke permissions at any time through Settings 
     if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) 
       != PackageManager.PERMISSION_GRANTED) { 

      // The permission is NOT already granted. 
      // Check if the user has been asked about this permission already and denied 
      // it. If so, we want to give more explanation about why the permission is needed. 
      if (shouldShowRequestPermissionRationale(
        Manifest.permission.READ_CONTACTS)) { 
       // Show our own UI to explain to the user why we need to read the contacts 
       // before actually requesting the permission and showing the default UI 
      } 

      // Fire off an async request to actually get the permission 
      // This will show the standard permission request dialog UI 
      requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, 
        READ_CONTACTS_PERMISSIONS_REQUEST); 
     } 
    } 

    // Callback with the request from calling requestPermissions(...) 
    @Override 
    public void onRequestPermissionsResult(int requestCode, 
              @NonNull String permissions[], 
              @NonNull int[] grantResults) { 
     // Make sure it's our original READ_CONTACTS request 
     if (requestCode == READ_CONTACTS_PERMISSIONS_REQUEST) { 
      if (grantResults.length == 1 && 
        grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       Toast.makeText(this, "Read Contacts permission granted", Toast.LENGTH_SHORT).show(); 
      } else { 
       Toast.makeText(this, "Read Contacts permission denied", Toast.LENGTH_SHORT).show(); 
      } 
     } else { 
      super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     } 
    } 
} 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if (resultCode == Activity.RESULT_OK) { 
      ContentResolver reContentResolverol = getContentResolver(); 
      Uri contactData = data.getData(); 
      @SuppressWarnings("deprecation") 
      Cursor cursor = managedQuery(contactData, null, null, null, null); 
      cursor.moveToFirst(); 
      String username = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
      String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 
      Cursor phone = reContentResolverol.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
        null, 
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, 
        null, 
        null); 
      while (phone.moveToNext()) { 
       String usernumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
       phone1.setText(usernumber); 
       name1.setText(username); 
      } 

     } 
    } 

}

あなたはREAD_CONTACTS許可、両方in the manifestとat runtimeを要求する必要があります。

また、​​は非推奨となりました。6年前となりました。それ以前は悪い考えでした。より新しいテクニックを使用してください（例：CursorLoader）。
