上一节中,我们实现了自己的notification,相信大家都有了一些认识,在最后也接受了利用RemoteView来实现自定义布局的notification,这里就来举一个示例,方便理解。
第一步:新建一个工程,命名为cusNotification;
第二步:新建一个布局文件(即自定义的notification的布局文件:custom_notification.xml,内容如下:
第三步:新建上面布局文件中引用到的styyes.xml文件,代码如下:
第四步:修改java源文件,代码如下:
public class CusNotificationActivity extends Activity { private static final int CUSTOM_VIEW_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //Notification notification = new Notification(); int icon = R.drawable.ic_launcher; CharSequence tickerText = "Notification01"; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification); contentView.setImageViewResource(R.id.image, R.drawable.notification_image); contentView.setTextViewText(R.id.title, "Custom notification"); contentView.setTextViewText(R.id.text, "This is a custom layout"); notification.contentView = contentView; Intent notificationIntent = new Intent(this, CusNotificationActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(CusNotificationActivity.this, 0, notificationIntent, 0); notification.contentIntent = contentIntent; String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); mNotificationManager.notify(CUSTOM_VIEW_ID, notification); }}第五步:运行程序,看看再notifications window中出现的效果如下:
当然,我们这里还和默认的布局效果做一下对比,下面的是使用默认的布局的效果图:
