无法获取电话号码并显示在Toast对象上

Question

我试图在toast对象的联系人列表中显示选择的联系人，我想显示名称和号码，但是当我选择联系人时我的应用程序停止工作，我不知道为什么。< / p>

这是我的代码：

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == REQUEST_SELECT_PHONE_NUMBER && resultCode == RESULT_OK) {
            // Get the URI and query the content provider for the phone number
            Uri contactUri = data.getData();
            String[] projection = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
            Cursor cursor = getContentResolver().query(contactUri, projection,
                    null, null, null);
            // If the cursor returned is valid, get the phone number
            if (cursor != null && cursor.moveToFirst()) {
                int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                String number = cursor.getString(numberIndex);
                String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));                // Do something with the phone number
                Context context = getApplicationContext();
                CharSequence text = "Hello toast!";
                int duration = Toast.LENGTH_SHORT;
                String fullContact = contactName + ": " + number;

                Toast toast = Toast.makeText(context,fullContact, duration);
                toast.show();
            }
        }
    }
