我想建立一個應用程序,用戶可以將他/她的location
發送到sqlitedatabase
中存儲的電話號碼。我測試了應用程序,用戶可以將文本信息location
發送到一個電話號碼,但它現在可以工作,但現在當我嘗試創建一個list
的數字並將其作爲sendTextMessage
方法smsManager
的location
作爲參數傳遞給一個文本消息不發送。我已經嘗試了以下至今給定的代碼,短信沒有被髮送到一個號碼列表,但只有一個號碼被指定時發送
代碼

location_button.setOnClickListener(new View.OnClickListener() {

SmsManager smsManager = SmsManager.getDefault();
// smsManager.sendTextMessage(number, null, message, null, null);
getContacts();
smsManager.sendTextMessage(String.valueOf(numbers),null,message,null,null);
Toast.makeText(getApplicationContext(), "SMS sent."+String.valueOf(numbers),
Toast.LENGTH_LONG).show();
}
}
註釋行是那些當我試圖只用一個電話號碼來測試應用程序。另外,假設最初在sqlitedatabase
中只有一個電話號碼,因爲我多次點擊location_button
,這是arraylist
多次增長的大小。例如,最初如果arraylist
有元素[xxxxxx]
下一次我點擊location_button
arraylist
現在將有[xxxxxx,xxxxxx]
。
任何人都可以幫我解決這個問題嗎?
'SmsManager'方法一次只能處理一個數字。你必須一一發送。 –
是不是有一種方法可以同時向多個號碼發送短信 –
您可以使用循環發送短信嗎? –
