Question

我正在尝试从Android应用程序发送短信，编写以下代码，但我收到编译错误：“无法找到符号变量SEND_SMS”。我还导入了“android.Manifest.permission”但未解决。请帮帮我。

案例R.id.SendSMS：

            // Here, thisActivity is the current activity
            if (ContextCompat.checkSelfPermission(this,
                    Manifest.permission.SEND_SMS)
                    != PackageManager.PERMISSION_GRANTED) {

                // Should we show an explanation?
                if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                        Manifest.permission.SEND_SMS)) {

                    // Show an expanation to the user *asynchronously* -- don't block
                    // this thread waiting for the user's response! After the user
                    // sees the explanation, try again to request the permission.

                } else {

                    // No explanation needed, we can request the permission.

                    ActivityCompat.requestPermissions(this,
                            new String[]{Manifest.permission.SEND_SMS},
                            MY_PERMISSIONS_REQUEST_SEND_SMS);

                    // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
                    // app-defined int constant. The callback method gets the
                    // result of the request.
                }
            }
            try {

               SmsManager smsManager = SmsManager.getDefault();
               smsManager.sendTextMessage(diaryEntry.getText().toString(),
                        null, diaryEntry.getText().toString(),
                        null, null);
                Toast.makeText(getApplicationContext(), "Your sms has successfully sent!",
                        Toast.LENGTH_LONG).show();
            } catch (Exception ex) {
                Toast.makeText(getApplicationContext(),"Your sms has failed...",
                        Toast.LENGTH_LONG).show();
                ex.printStackTrace();
            }

        </application>

</manifest>

Answer 1

我用这个

解决了这个问题

android.Manifest.permission.SEND_SMS;

而不是

Manifest.permission.SEND_SMS

Answer 2

这有效：

import android.Manifest;
...
String p = Manifest.permission.SEND_SMS;

找不到符号变量SEND_SMS
