Question

在以下代码中使用SMS Manager发送短信：

SmsManager smsManager = SmsManager.getDefault();                                                      
smsManager.sendTextMessage(phoneNo, null,message, null, null);

在下面的对话框中，当设备安卓版4.3或4.4时我收到它。如果单击发送或取消，如何检测状态？

Answer 1

如果您阅读相应的源代码，只要单击“发送”或“取消”，您就会发现无法检测到状态。

“将消息发送到高级短信短代码（或可疑的高级短信号码）的默认行为是要求用户进行确认。允许用户设置默认策略（”记住此选项“复选框） /永远不允许应用程序在将来向优质短代码发送短信。可以通过应用信息屏幕中的设置应用更改政策。“ See here for details

对话框定义于 src / java / com / android / internal / telephony / SMSDispatcher.java

 /**
* Post an alert when SMS needs confirmation due to excessive usage.
* @param tracker an SmsTracker for the current message.
*/
protected void handleReachSentLimit(SmsTracker tracker) {
    if (denyIfQueueLimitReached(tracker)) {
        return; // queue limit reached; error was returned to caller
    }
    CharSequence appLabel = getAppLabel(tracker.mAppInfo.packageName);
    Resources r = Resources.getSystem();
    Spanned messageText = Html.fromHtml(r.getString(R.string.sms_control_message, appLabel));
    ConfirmDialogListener listener = new ConfirmDialogListener(tracker);
    AlertDialog d = new AlertDialog.Builder(mContext)
           .setTitle(R.string.sms_control_title)
           .setIcon(R.drawable.stat_sys_warning)
           .setMessage(messageText)
           .setPositiveButton(r.getString(R.string.sms_control_yes), listener)
           .setNegativeButton(r.getString(R.string.sms_control_no), listener)
           .setOnCancelListener(listener)
           .create();
   d.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
   d.show();
  }

负面和正面按钮的回调：

 /**
* Dialog listener for SMS confirmation dialog.
*/
private final class ConfirmDialogListener
implements DialogInterface.OnClickListener, DialogInterface.OnCancelListener,
CompoundButton.OnCheckedChangeListener {
    private final SmsTracker mTracker;
    private Button mPositiveButton;
    private Button mNegativeButton;
    private boolean mRememberChoice; // default is unchecked
    ConfirmDialogListener(SmsTracker tracker) {
       mTracker = tracker;
    }
    void setPositiveButton(Button button) {
       mPositiveButton = button;
    }
    void setNegativeButton(Button button) {
      mNegativeButton = button;
    }
@Override
    public void onClick(DialogInterface dialog, int which) {
// Always set the SMS permission so that Settings will show a permission setting
// for the app (it won't be shown until after the app tries to send to a short code).
      int newSmsPermission = SmsUsageMonitor.PREMIUM_SMS_PERMISSION_ASK_USER;
      if (which == DialogInterface.BUTTON_POSITIVE) {
         Log.d(TAG, "CONFIRM sending SMS");
// XXX this is lossy- apps can have more than one signature
         EventLog.writeEvent(EventLogTags.SMS_SENT_BY_USER,
         mTracker.mAppInfo.signatures[0].toCharsString());
         sendMessage(obtainMessage(EVENT_SEND_CONFIRMED_SMS, mTracker));
         if (mRememberChoice) {
             newSmsPermission = SmsUsageMonitor.PREMIUM_SMS_PERMISSION_ALWAYS_ALLOW;
         }
         } else if (which == DialogInterface.BUTTON_NEGATIVE) {
             Log.d(TAG, "DENY sending SMS");
// XXX this is lossy- apps can have more than one signature
        EventLog.writeEvent(EventLogTags.SMS_DENIED_BY_USER,
            mTracker.mAppInfo.signatures[0].toCharsString());
            sendMessage(obtainMessage(EVENT_STOP_SENDING, mTracker));
        if (mRememberChoice) {
            newSmsPermission = SmsUsageMonitor.PREMIUM_SMS_PERMISSION_NEVER_ALLOW;
        }
    }
       setPremiumSmsPermission(mTracker.mAppInfo.packageName, newSmsPermission);
}

当您单击对话框上的“发送”或“取消”按钮时，它将在其线程中向其处理程序发送消息。但似乎没有办法捕获点击事件。
