我的应用程序中有一些文件,但其中只有3个文件很重要。这是一个提醒应用程序与报警声音和通知。 我有一个maincode.java文件,其中包含一个复选框及其侦听器。如果用户检查chechbox,AlarmManager会将意图发送到启动MyService.java的AlarmReceiver.java。 MyService java包含有关播放声音的代码。代码是部分的。 MyService.java:Android AlarmManager和服务问题
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
player = MediaPlayer.create(this, R.raw.sound);
player.setLooping(false); // Set looping
}
@Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
player.stop();
}
@Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
player.start();
}
AlarmReceiver.java:
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
player = MediaPlayer.create(this, R.raw.sound);
player.setLooping(false); // Set looping
maincode.java的重要组成部分:
cb1 = (CheckBox) findViewById(R.id.CheckBox01);
cb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
if (cb1.isChecked())
{
if (GlobalVars.getHourOfDay() >= 0)
{
Toast.makeText(maincode.this, "ok", Toast.LENGTH_SHORT).show();
rem1.setText(GlobalVars.getReminder1name());
Intent intent = new Intent(maincode.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(bInsulinReminder.this, 0,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, GlobalVars.getHourOfDay());
cal.set(Calendar.MINUTE, GlobalVars.getMinute());
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis()+ 3000, 6000, pendingIntent);
}
Toast.makeText(maincode.this, "Checked", Toast.LENGTH_SHORT).show();
} else {
rem1.setText("No reminder set");
Toast.makeText(maincode.this, "Not checked", Toast.LENGTH_SHORT).show();
}
}
});
(REM1是在提醒按钮,其文本取决于名任何用户想要的)
问题的代码是,如果我开始警报,我无法阻止它。我知道MyService.java中有player.stop()命令,但是我怎样才能从maincode.java的末尾调用它,其中复选框未选中?
