我在微调器选择的值中出错

Question

我正在尝试制作一个应用程序来发送带有默认或用户预定义消息和 phone 号码的消息我将把我的代码放在这里

 private static final int MY_PERMISSIONS_REQUEST_SEND_SMS = 0;
String phoneNo, message;
List<String> pn, txt;
Spinner sp1, sp2;
Button b, b1, b2, b3, b4;
EditText et, et1;

ArrayAdapter<String> adp1, adp2;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    setupSpinners();

    b = (Button) findViewById(R.id.button);
    b1 = (Button) findViewById(R.id.button1);
    b2 = (Button) findViewById(R.id.button2);
    b3 = (Button) findViewById(R.id.button3);
    b4 = (Button) findViewById(R.id.button4);
    et = (EditText) findViewById(R.id.editText);
    et1 = (EditText) findViewById(R.id.editText1);

    b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            adp1.add(et.getText().toString());
            et.setText(null);
        }

    });

    b2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            adp2.add(et1.getText().toString());
            et1.setText(null);
        }

    });
}

public void setupSpinners() {

    sp1 = (Spinner) findViewById(R.id.spinner);
    sp2 = (Spinner) findViewById(R.id.spinner1);
    pn = new ArrayList<String>();
    txt = new ArrayList<String>();
    txt.add("Sorry Boss I'cant go today i'm sick");
    pn.add("123456789");

    adp1 = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, pn);
    adp2 = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, txt);

    sp1.setAdapter(adp1);
    sp1.setSelection((pn.size() - 1));
    sp2.setAdapter(adp2);
    sp2.setSelection((txt.size() - 1));

    sp1.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            sp1.setSelection(arg2);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
        }


    });
    sp2.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            sp2.setSelection(arg2);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

            b4.setOnClickListener(new View.OnClickListener() {
                public void onClick(View view) {
                    sendSMSMessage();
                }

                protected void sendSMSMessage() {
                    phoneNo =  sp1.getSelectedItem().toString();
                    message =  sp2.getSelectedItem().toString();

                    if (ContextCompat.checkSelfPermission(this,
                            Manifest.permission.SEND_SMS)
                            != PackageManager.PERMISSION_GRANTED) {
                        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                                Manifest.permission.SEND_SMS)) {
                        } else {
                            ActivityCompat.requestPermissions(this,
                                    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, message, null, null);
                                Toast.makeText(getApplicationContext(), "SMS sent.",
                                        Toast.LENGTH_LONG).show();
                            } else {
                                Toast.makeText(getApplicationContext(),
                                        "SMS faild, please try again.", Toast.LENGTH_LONG).show();
                                return;
                            }
                        }
                    }

                }
            });
        }
    });
}

报错的部分是(this,

if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
 Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);

我需要帮助来了解如何 select 微调器 selected 值以通过文本发送。

Answer 1

pn和txt变量是Lists，Lists上没有getText()这样的方法。

Answer 2

这是在微调器中获取选定值的一行代码。

String text = mySpinner.getSelectedItem().toString();

在你的代码中

protected void sendSMSMessage() {
                    phoneNo =  sp1.getSelectedItem().toString();
                    message =  sp2.getSelectedItem().toString();

我在微调器选择的值中出错
