java - 从 SMSPortalFragment 发送短信不起作用

Question

我一直在尝试使用 send_sms api 发送测试消息。 我的 SMSPortalFragment.java 代码没有显示错误。 Logcat 中也没有显示其他错误。

1. 代码在 Galaxy S8 中构建并安装。
2. 应用程序运行起来很有趣。
3. 转至 fragment_smsportal.xml 工作正常。
4. 我可以输入我的姓名和消息。
5. 单击按钮时，它会在运行时询问我的PERMISSION。
6. 即使我允许许可，也不会发送任何消息。

java代码:

private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;

Button sendButon;
EditText fullName;
EditText textMessage;
String phoneNo = "***********";
String name;
String message;
String sendMessage;

public SMSPortalFragment() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View smsportal = inflater.inflate(R.layout.fragment_smsportal, container, false);

    fullName = (EditText) smsportal.findViewById(R.id.fullName);
    textMessage = (EditText) smsportal.findViewById(R.id.textMessage);
    sendButon = (Button) smsportal.findViewById(R.id.sendButon);

    sendButon.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sendSMSMessage();
        }
    });

    return smsportal;
}

private void sendSMSMessage() {
    name = fullName.getText().toString();
    message = textMessage.getText().toString();
    sendMessage = name + " " + message;


    if (ContextCompat.checkSelfPermission(getActivity(),
            Manifest.permission.SEND_SMS)
            != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
                Manifest.permission.SEND_SMS)) {
        } else {
            ActivityCompat.requestPermissions(getActivity(),
                    new String[]{Manifest.permission.SEND_SMS},
                    MY_PERMISSIONS_REQUEST_SEND_SMS);
        }
    }
}
@Override
public void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_SEND_SMS: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                SmsManager smsManager = SmsManager.getDefault();
                smsManager.sendTextMessage(phoneNo, null, sendMessage, null, null);
                Toast.makeText(getActivity(),"SMS sent.", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(getActivity(),"SMS failed, please try again.", Toast.LENGTH_LONG).show();
            }
        }
    }

}

谁能告诉我我做错了什么？

PS:出于安全考虑，我从此代码中删除了我的电话号码。

Do not write your send logic in onRequestPermissionsResult()and

试试这个...

Manifest permission

<uses-permission-sdk-23 android:name="android.permission.SEND_SMS"/>

and here is the snippet

   try {
            Bundle msgDataBundle = intent.getExtras();
            String mobileNumber = msgDataBundle.getString("MobileNumber");
            SmsManager smsManager = SmsManager.getDefault();
            //  smsManager.sendTextMessage(mobileNumber,null,"sam",null,null);
            smsManager.sendTextMessage(mobileNumber, null, "Test Sample Message Text", null, null);
            Toast.makeText(context, "SMS Sent!", Toast.LENGTH_LONG).show();
            Log.d("---", "Sent");

        } catch (Exception e) {
            Toast.makeText(context, "SMS faild, please try again.", Toast.LENGTH_LONG).show();
            Log.d("---", "Fail");
            e.printStackTrace();
        }
