这是一个闹钟应用程序。 当警报声响起时,我无法停止。我要单击按钮停止铃声。
我使用的代码如下:
MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
alarmTimePicker = (TimePicker) findViewById(R.id.timePicker);
alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
}
public void OnToggleClicked(View view)
{
long time;
if (((ToggleButton) view).isChecked())
{
Toast.makeText(MainActivity.this, "ALARM ON", Toast.LENGTH_SHORT).show();
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getCurrentHour());
calendar.set(Calendar.MINUTE, alarmTimePicker.getCurrentMinute());
Intent intent = new Intent(this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
time=(calendar.getTimeInMillis()-(calendar.getTimeInMillis()%60000));
if(System.currentTimeMillis()>time)
{
if (calendar.AM_PM == 0)
time = time + (1000*60*60*12);
else
time = time + (1000*60*60*24);
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, time, 10000, pendingIntent);
}
else
{
alarmManager.cancel(pendingIntent);
Toast.makeText(MainActivity.this, "ALARM OFF", Toast.LENGTH_SHORT).show();
}
AlarmReceiver.java
public class AlarmReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Toast.makeText(context, "Alarm! Wake up! Wake up!", Toast.LENGTH_LONG).show();
Uri alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
if (alarmUri == null)
{
alarmUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
}
Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
ringtone.play();
}
}
答案 0 :(得分:1)
RingtoneManager.stopPreviousRingtone()
甚至更好。存储原始铃声并呼叫stop
。
Ringtone ringtone = RingtoneManager.getRingtone(getActivity());
ringtone.play();
...
ringtone.stop();
