实现了自己的notification,需要利用RemoteView来实现自定义布局,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:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentLeft="true" android:layout_marginRight="10dp" android:contentDescription="@string/Image" /> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/image" style="@style/NotificationTitle" /> <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/image" android:layout_below="@id/title" style="@style/NotificationText" /> </RelativeLayout>
第三步:新建上面布局文件中引用到的styyes.xml文件,代码如下:
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent" /> <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title" /> </resources>
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);
}
}
这里主要是讲解自定义布局notification的实现,并没有做出很炫的效果!就到这吧!
