Android 如何设置警报以在特定时间显示祝酒词

我想根据用户的要求从timepicker获取输入，然后我想在那个时候显示一条toast消息。，。我尝试了以下方法，但不起作用

for (int i = 0; i < mNameList.size(); i++) {
                    Log.i("mName is ", ""
                            + mNameList.get(i).getText().toString());
                    Log.i("Time is ", "" + timeList.get(i).getText().toString());
                    String[] time = timeList.get(i).getText().toString()
                            .split(":");
                    int hour = Integer.parseInt(time[0]);
                    int min = Integer.parseInt(time[1]);
                    Log.i("Hour", "" + hour);
                    Log.i("Min", "" + min);

                    Intent intent = new Intent(MainActivity.this,
                            AlarmReciever.class);
                    PendingIntent alarmIntent = PendingIntent.getBroadcast(
                            MainActivity.this, 0, intent,
                            PendingIntent.FLAG_UPDATE_CURRENT);
                    AlarmManager aManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

                    Calendar firingcal = Calendar.getInstance();
                    Calendar currentcal = Calendar.getInstance();

                    firingcal.set(Calendar.HOUR, hour);
                    firingcal.set(Calendar.MINUTE, min);

                    long intendedTime = firingcal.getTimeInMillis();
                    long currentTime = currentcal.getTimeInMillis();
                    if (intendedTime >= currentTime) {
                        aManager.setRepeating(AlarmManager.RTC_WAKEUP,
                                intendedTime, AlarmManager.INTERVAL_DAY,
                                alarmIntent);
                    } else {
                        firingcal.add(Calendar.DAY_OF_MONTH, 1);
                        intendedTime = firingcal.getTimeInMillis();

                        aManager.setRepeating(AlarmManager.RTC_WAKEUP,
                                intendedTime, AlarmManager.INTERVAL_DAY,
                                alarmIntent);
                    }
                }

我在清单中提到了我的接收者姓名。那么如何在特定时间显示toast。

在清单中添加以下内容：

<receiver android:name="Your.Package.Name.AlarmReciever" />

public static AlarmManager am;
public static PendingIntent sender;
try {

            Intent intent1 = new Intent(thisActivity, AlarmReciever.class);
            sender = PendingIntent.getBroadcast(thisActivity, 2, intent1 ,0);
            am = (AlarmManager) getSystemService(ALARM_SERVICE);
            long l = new Date().getTime();
            if (l < new Date().getTime()) {
                l += 100;
            }
            am.setRepeating(AlarmManager.RTC_WAKEUP, l, 100, sender);
        } catch (Exception e) {
        }

然后在主活动中添加以下内容：

<receiver android:name="Your.Package.Name.AlarmReciever" />

public static AlarmManager am;
public static PendingIntent sender;
try {

            Intent intent1 = new Intent(thisActivity, AlarmReciever.class);
            sender = PendingIntent.getBroadcast(thisActivity, 2, intent1 ,0);
            am = (AlarmManager) getSystemService(ALARM_SERVICE);
            long l = new Date().getTime();
            if (l < new Date().getTime()) {
                l += 100;
            }
            am.setRepeating(AlarmManager.RTC_WAKEUP, l, 100, sender);
        } catch (Exception e) {
        }

将闹钟设置为：

Intent intent = new Intent();
        intent.setClass(_Context, OnAlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(_Context, 234324243, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarmManager = (AlarmManager) _Context.getSystemService(Activity.ALARM_SERVICE);

        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.HOUR_OF_DAY, 4);
        cal.add(Calendar.MINUTE, 30);
        cal.add(Calendar.SECOND, 00);

        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,
                cal.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY,
                pendingIntent);

现在在menifest文件中设置接收器，如下所示：

<receiver android:name="com.televero.receiver.OnAlarmReceiver" >
        </receiver>

希望这能奏效。

通过谷歌搜索，我找到了问题的答案。答案如下..参考和

for（int i=0；iif（firingcal.compareTo（currentcal）尝试调试它并检查DendeTime和currentTime的预期时间和当前时间值是否正确，它们是否正确。我需要给出我的报警时间和长度的位置l=new Date（）.getTime（）；if（l<receiver android:name="com.televero.receiver.OnAlarmReceiver" >
        </receiver>

for (int i = 0; i < mNameList.size(); i++) {
                    Log.i("mName is ", ""
                            + mNameList.get(i).getText().toString());
                    Log.i("Time is ", "" + timeList.get(i).getText().toString());
                    String[] time = timeList.get(i).getText().toString()
                            .split(":");
                    int hour = Integer.parseInt(time[0]);
                    int min = Integer.parseInt(time[1]);
                    Log.i("Hour", "" + hour);
                    Log.i("Min", "" + min);

                    Calendar firingcal = Calendar.getInstance();
                    Calendar currentcal = Calendar.getInstance();

                    firingcal.set(Calendar.MONTH, 3);
                    firingcal.set(Calendar.YEAR, 2014);
                    firingcal.set(Calendar.DAY_OF_MONTH, 9);
                    firingcal.set(Calendar.HOUR_OF_DAY, hour);
                    firingcal.set(Calendar.MINUTE, min);
                    firingcal.set(Calendar.SECOND, 00);

                    if (firingcal.compareTo(currentcal) <= 0) {
                        Toast.makeText(MainActivity.this, "Invalid date/time",
                                Toast.LENGTH_LONG).show();

                    } else {
                        Log.i("Alarm Time in else is  ",
                                "" + firingcal.getTime());
                        scheduleAlarm(firingcal);
                    }

                }
            }


public void scheduleAlarm(Calendar alarmTime) {

        Toast.makeText(MainActivity.this,
                "Alarm time is set at" + alarmTime.getTime(), Toast.LENGTH_LONG)
                .show();
        Intent intent = new Intent(MainActivity.this, AlarmReciever.class);
        final int _id = (int) System.currentTimeMillis();
        PendingIntent pIntent = PendingIntent.getBroadcast(MainActivity.this,
                _id, intent, 0);
        AlarmManager aManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        aManager.set(AlarmManager.RTC_WAKEUP, alarmTime.getTimeInMillis(),
                pIntent);

    }
