I'm a student learning programming in Android Studio and I met some difficulties when developing my Alarm clock project. I've done lots of experiments and research in my code but still I couldn't find the solution. I wanted to try to make a normal alarm that is when the alarm is activated, display another full screen activity to remind the user. I don't want my alarm app to just ring and toast notification. I want it to also display a screen.
Here is my code:
And this is the manifest, not sure what I'm doing is right.Thank you for helping.
Here is my code:
Java:
import java.util.Calendar;
import static android.R.id.message;
import static android.provider.AlarmClock.EXTRA_MESSAGE;
public class MainActivity extends AppCompatActivity
{
TimePicker alarmTimePicker;
PendingIntent pendingIntent;
AlarmManager alarmManager;
@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);
}
// Toggle button
public void OnToggleClicked(View view)
{
long time;
if (((ToggleButton) view).isChecked())
{
Toast.makeText(MainActivity.this, "Activated", Toast.LENGTH_SHORT).show();
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getCurrentHour());
calendar.set(Calendar.MINUTE, alarmTimePicker.getCurrentMinute() + 1);
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, 120000, pendingIntent);
}
else
{
Toast.makeText(MainActivity.this, "OFF", Toast.LENGTH_SHORT).show();
alarmManager.cancel(pendingIntent);
}
}
}And this is the manifest, not sure what I'm doing is right.Thank you for helping.
