我想拒絕來電後發送短信。 應用程序正在發送短信,但問題是它發送兩次。我無法弄清楚問題在哪裏。呼叫拒絕後發送短信 - 多次發送
下面是使用的代碼。
public class CallBarring extends BroadcastReceiver
{
private String number;
@Override
public void onReceive(Context context, Intent intent)
{
// If, the received action is not a type of "Phone_State", ignore it
if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
return;
// Else, try to do some action
else
{
// Fetch the number of incoming call
number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
// Check, whether this is a member of "Black listed" phone numbers stored in the database
if(MainActivity.blockList.contains(new Blacklist(number)))
{
// If yes, invoke the method
disconnectPhoneItelephony(context);
sendSMS(context);
// return;
}else{
disconnectPhoneItelephony(context);
sendSMS(context);
}
}
}
public void sendSMS(Context context) {
try{
String message = SharedPrefActivity.CommonMethod.getPrefsData(context, SharedPrefActivity.Constants.TextMessage, "");
Intent intent=new Intent(context,CallBarring.class);
PendingIntent pi=PendingIntent.getActivity(context, 0, intent,0);
SmsManager sms=SmsManager.getDefault();
sms.sendTextMessage(number, null, message, pi,null);
Toast.makeText(context, "SMS Sent", Toast.LENGTH_LONG).show();
} catch (Exception e)
{
Toast.makeText(context, "SMS faild, please try again later!", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
// Method to disconnect phone automatically and programmatically
// Keep this method as it is
@SuppressWarnings({ "rawtypes", "unchecked" })
private void disconnectPhoneItelephony(Context context)
{
ITelephony telephonyService;
TelephonyManager telephony = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE);
try
{
Class c = Class.forName(telephony.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService = (ITelephony) m.invoke(telephony);
telephonyService.endCall();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
很抱歉,但你如果沒有代碼,否則阻止一樣嗎?那麼有什麼意義呢? –
'MainActivity.blockList'是靜態的嗎?如果是這樣,你怎麼填充它?你正在調用同樣的斷開連接條件併發送短信,那爲什麼呢? –
代碼不起作用.... –
