相关疑难解决方法(0)

在a中使用PendingIntent时AppWidgetProvider,我使用以下代码:

views.setOnClickPendingIntent( viewId,
                PendingIntent.getBroadcast( context, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT ) );

所以目前没有对getBroadcast方法返回的PendingIntent的引用.在特定情况下,我现在想要取消PendingIntent.有没有办法从视图中获取PendingIntent？或者是之后通过保持对它的引用来调用PendingIntent的cancel方法的唯一方法？

我正在制作一个短信计划应用程序,它只需要用户的时间,短信和号码,并在给定时间发送短信.我在用PendingIntent.这是我的示例代码.

当用户创建计划时,它只是调用此方法.

private void SendMessages()
    {
        Intent intent = new Intent(this, SMSBroadcastReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                this.getApplicationContext(), 234324243, intent, 0);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, Timemilli, pendingIntent);
    }

这是'SMSBroadcastReceiver.java'文件

public class SMSBroadcastReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Toast.makeText(context, "SMS Sent !!!!.", Toast.LENGTH_LONG)
                .show();
        // //Sms Sending

        try
        {
            SmsManager smsManager = SmsManager.getDefault();
            for (int i = 0; i < SMSScheduleContactsActivity.SelectedContacts.length; i++)
            {
                smsManager.sendTextMessage(
                        SMSScheduleContactsActivity.SelectedContacts[i], null,
                        AddNewSmsSchedule.Message, null, null);
            }

            Log.d("testllllllllllllllll", "Message …
