The Card

Le Card sono alla basedella UI di Android Wear

Sono molto più che notifiche.

Le Card appaiono solo se invocate o se strettamente necessarie all’utente in un certo istante.

notificationManager.notify(notificationId,notifBuilder.build());

Build notification

Test!

Let’sInteract

Create intentreciever

public class NotificationReceiver extends BroadcastReceiver{

public static final String ACTION_START = "com.giux.wearun.ACTION_START";

@Overridepublic void onReceive(Context context, Intent intent) {

String action = intent.getAction();MainActivity.start();

}}

<application><receiver android:name="com.giux.wearun.NotificationReceiver" android:exported="true" > <intent-filter> <action android:name="com.giux.wearun.ACTION_START"/> <action android:name="com.giux.wearun.ACTION_LAP"/> <action android:name="com.giux.wearun.ACTION_STOP"/> </intent-filter> </receiver>

</application>

Intent &manifest

Intent intent = new Intent(NotificationReceiver.ACTION_START).setClass(getBaseContext(), NotificationReceiver.class);

PendingIntent pending = PendingIntent.getBroadcast(getBaseContext(), notifId, intent,

0);…

.addAction(R.drawable.ic_start, "Start", pending );

….

addAction

Test!

Add anotherAction!

public class NotificationReceiver extends BroadcastReceiver{

public static final String ACTION_START = "com.giux.wearun.ACTION_START";

public static final String ACTION_LAP ="com.giux.wearun.ACTION_LAP";

public static final String ACTION_STOP = "com.giux.wearun.ACTION_STOP";

Edit the Broadcast Reciever

@Overridepublic void onReceive(Context context, Intent intent) {

String action = intent.getAction();

switch (action) {case ACTION_START:

MainActivity.start();break;

…default:

break;}

Edit the Intent Reciever

public PendingIntent createIntent(String extra, int notifId){Intent intent = null;

switch (extra) {case "start":

intent = new Intent(NotificationReceiver.ACTION_START).setClass(getBaseContext(),

NotificationReceiver.class);break;…

}PendingIntent pending =

PendingIntent.getBroadcast(getBaseContext(), notifId, intent, 0);

return pending;}

More Intent

public void notif(){…

.setContentTitle("Lap Time").setContentText("Swipe to save the lap time").addAction(R.drawable.ic_start, "Start", createIntent("start", notificationId))//ToDo

NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getApplicationContext());

notificationManager.notify(notificationId, notifBuilder.build());

}

More Action

That’sAll!
