小编Cod*_*ior的帖子

我想在我的应用程序中添加一些动画.请找到附带的照片以获得动画创意.

我用过CoordinatorLayout.我的搜索布局和工具栏托管在AppBarLayout/CollapsingToolbarLayout中.下面是我的NestedScrollView托管片段.

当用户使用滚动标志滚动时,我能够隐藏搜索布局.我正在尝试实现一个CoordinatorLayout.Behavior,它将开始向左移动购物车图标并开始搜索图标从0到1缩放; 一旦用户滚动并且搜索布局开始隐藏.当搜索布局完全隐藏时,我想在第二个屏幕中显示工具栏.当用户向下滚动并且通过向右移动推车并缩小搜索图标开始显示搜索布局时,它将返回到原始状态,如第一个屏幕所示.

最初我将工具栏上的搜索图标设为隐藏,购物车图标和搜索图标位于线性布局内.

请找到我的xml activity_home_page.xml

我已经使用RemoteViews小部件实现了自定义通知.我在Android 5.0.2和Android 6.0上测试过它.它工作正常.但过了一段时间,它每次收到GCM的通知时都会崩溃.

崩溃转储 -

我的RemoteViews布局在LinearLayout中有Imageview,自定义TextView类扩展TextView.

我创建通知的代码是

    private void showCustomNotification(ABCNotification notification) {
        RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.layout_notification);
        PendingIntent contentPendingIntent = PendingIntent.getBroadcast(mContext, 0, notification.getContentIntent(), PendingIntent.FLAG_UPDATE_CURRENT);

                NotificationCompat.Builder builder = new NotificationCompat.Builder(mContext);
                builder.setSmallIcon(R.drawable.ic_notification).setAutoCancel(true).setContentIntent(contentPendingIntent);

                // Set Notification Priority
                builder.setPriority(notification.getNotificationPriority()); …
