我正在开发Android应用。最后一次使用带有锁定屏幕上显示的自定义视图的通知。不幸的是,当我像其他通知一样点击它时,我无法获得波纹和高程效果。此外,单个触摸触发我已配置的意图,而其他通知需要双击。
我在Github上放了一个最小的项目示例:
https://github.com/lpellegr/android-notification-custom-example
该应用示例提供了两个发布通知的按钮:一个使用自定义视图并受到上述问题的影响,另一个使用默认系统视图且具有预期行为的通知。
欢迎任何关于如何获得波纹和高程效果以及双击行为(通过保持自定义视图)的想法。
PS:我的目标是API 19+,我希望使用自定义视图布局以及 setOnClickPendingIntent ,因为只有此侦听器允许打开活动,无论设备的安全模式如何是

从方法setOnClickPendingIntent
中删除publishNotificationWithCustomView
,然后将setContentIntent
添加到通知构建器中:
private void publishNotificationWithCustomView() {
String title = "Notification Custom View";
String content = "No ripple effect, no elevation, single tap trigger";
Context context = getApplicationContext();
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setWhen(System.currentTimeMillis())
.setDefaults(DEFAULT_ALL)
.setSmallIcon(R.mipmap.ic_launcher)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setOnlyAlertOnce(true)
.setAutoCancel(false)
.setColor(ContextCompat.getColor(context, R.color.colorAccent))
.setContentTitle(title)
.setContentText(content)
.setOngoing(true)
.setCategory(NotificationCompat.CATEGORY_ALARM)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentIntent(createLockscreenNotificationPendingIntent(context));
int notificationLayoutResId = R.layout.lock_screen_notification;
// using folder layout-vX is having issue with LG devices
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
notificationLayoutResId = R.layout.lock_screen_notification_android_n;
}
RemoteViews remoteView = new RemoteViews(
context.getPackageName(), notificationLayoutResId);
remoteView.setTextViewText(R.id.title, title);
remoteView.setTextViewText(R.id.text, content);
builder.setCustomContentView(remoteView);
Notification notification = builder.build();
publishNotification(context, notification, 7);
}
然后从android:clickable="true"
和lock_screen_notification.xml
lock_screen_notification_android_n.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="64dp">
