We want a special sound for our wake clock, let make an alarm clock android app.
Create a file name wake.xml in folder
layout.

We create a float view on lock screen, inform Alarm on and time to
wake. If user touch view, we quit alarm. Command in onDestroy() we destroy
events if it happened, we use count variables to detect. If not use this way,
app will crash because we destroy nothing.

Add function to check if service is running.
public static boolean isRunning(Context context) {
ActivityManager
manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
for
(ActivityManager.RunningServiceInfo service
: manager.getRunningServices(Integer.MAX_VALUE)) {
if (service.class.getName().equals(service.service.getClassName())){
return true;
}
}
return false;
}
Add function to turn off alarm when press textView.
public void quit(View v) {
on.setText("OFF");
on.setTextColor(Color.RED);
on.setBackgroundColor(Color.LTGRAY);
on.setTypeface(null, Typeface.NORMAL);
stopService(new Intent(wakeclock.this, service.class));
}
We get choose time from spinner, save, when reopen, it show
choosen time.
When press OK, passing data to service to set alarm time on lock
screen.
If alarm On, user press textView ON. It will turn OFF.
To open class wakeclock if it ‘s not main class
Intent
in = new Intent(MainActivity.this, wakeclock.class);
startActivity(in);
Custom spinner see this post.
