Android L SoundPool.load() regression

由 本小妞迷上赌 提交于 2019-12-04 08:03:50
问题 On Android L - the latest developer preview (Nexus 5), there seems to be a regression in the SoundPool.load() method which takes >5 seconds to load a sample (<100kb), where samples were loaded on pre-L systems instantly with the very same code. I tried OGG or MP3, both with same results. Tried different sizes but all under 100kb. Seems as 40kb or 80kb does not make any difference, so does OGG or MP3. Loading is always around 5s delay. This seems as yet another regression in SoundPool after

Is there a way to share a same LayoutManager between multiple nested RecyclerViews

由 旧巷老猫 提交于 2019-12-04 08:01:14
I'm developing an application that showing a game list, inside every game's itemView, i also have a video list to be showing. preview and structure are following. I deploy a RecyclerView as the window root view, and then for the videos, i used grid-style RecyclerView to display, so here we got a nested RecyclerView structure. But there is trouble because the number of videos is inconsistent between games, i don't want the RecyclerView of video list able to being scroll, so the best way is make the View's height stretch dynamically depends on how much rows it have. I heard a disappointing

Android shared elements with Picasso

由 前提是你 提交于 2019-12-04 07:41:35
I'm trying to make an image transit from a list in one activity to a detail activity. In the detail activity the image is bigger than in the list and I'm using Picasso to retrieve the image from the server. The problem is that the first time I launch the detail activity, the image transit well but is not resized nor centered. When I go back, the image is instantly resized, and if I come back to the same detail activity, it works as expected. The detail activity call method: public static void launch(Activity activity, View transitionView, StoreProduct storeProduct) { ActivityOptionsCompat

How can I Animate the color change of the statusbar and toolbar (like the new Calendar app does)

由 自闭症网瘾萝莉.ら 提交于 2019-12-04 07:27:10
问题 The new Google Calendar app has an animation I would like to do in my app. When you create a new event you can choose a color for the event. When you do, the statusbar and toolbar change to that color with a circular effect that covers both of them. Here's an example of what I'd like to do: I can change the color of the statusbar and toolbar, but how can I apply the circular animation effect (or similar) to both of them as the color is changed? 回答1: I don't know if this is the exact way the
