Android AlarmManager
Ok, I've tried two examples of AlarmManager- one from the commonsware website, and one from the manning website. The code I am currently working with is from the manning website : [http://unlocking-android.googlecode.com/svn/chapter8/trunk/SimpleAlarm/][1]
There are two classes, AlarmReceiver and GenerateAlarm. Anyone have any idea why the toast will not display in the emulator? I was thinking that it was because I am located in the Eastern Time Zone and it uses UTC, but I have fiddled with different things and none of them seem to work.
public class GenerateAlarm extends Activity {
Toast mToast;
@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.set_alarm_button);
button.setOnClickListener(this.mOneShotListener);
}
private OnClickListener mOneShotListener = new OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(GenerateAlarm.this, AlarmReceiver.class);
PendingIntent appIntent = PendingIntent.getBroadcast(GenerateAlarm.this, 0, intent, 0);
Calendar 开发者_运维知识库calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// calendar.add(Calendar.MINUTE, 1);
calendar.add(Calendar.SECOND, 10);
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), appIntent);
if (GenerateAlarm.this.mToast != null) {
GenerateAlarm.this.mToast.cancel();
}
GenerateAlarm.this.mToast = Toast.makeText(GenerateAlarm.this, R.string.alarm_message, Toast.LENGTH_LONG);
//GenerateAlarm.this.mToast.show();
}
};
}
public class AlarmReceiver extends BroadcastReceiver {
public void onReceiveIntent(Context context, Intent intent) {
Toast.makeText(context, R.string.app_name, Toast.LENGTH_SHORT).show();
}
@Override
public void onReceive(Context context, Intent intent) {
}
}
You have to add your toast in the onReceived
method where you should add the handling of the intent received.
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, R.string.app_name, Toast.LENGTH_SHORT).show();
}
onReceiveIntent
is not a method of broadcastreceiver
public abstract void onReceive (Context context, Intent intent)
Since: API Level 1 This method is called when the BroadcastReceiver is receiving an Intent broadcast.
