android - Android 发送短信前提示

Question

我是 Android 的新手，我正在尝试通过 Android 应用程序发送短信。我需要这样，如果消息包含单词“MYSELF”提示用户他们是否要继续发送 SMS 我的方法是:

public void sendSmsByManager() {

        try {

            // Get the default instance of the SmsManager

            SmsManager smsManager = SmsManager.getDefault();

            smsManager.sendTextMessage(phoneNumber.getText().toString(),
            null,
            smsBody.getText().toString(),
            null,
            null);
             //If the SMS Contains the WORD MYSELF Prompt the User If they Want to send the SMS

            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();

        }

    }

我怎样才能做到这一点？

创建警报确认样式对话框。

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Some Message");
    builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               //send text
           }
       });
    builder.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
               //discard text
           }
       });

    AlertDialog dialog = builder.create();
    dialog.show();
