[android-developers] [Help] Recognize vertical swiping and vertical scrolling in gridview
Hi all, I am a junior android dev, I have a question, please help me. I have a Gridview, include hundred of items (thumbnail images). I set a multi-select mode, in this mode, user just need to swipe his finger to start selecting multiple items (this case, gridview can not be scrolled). And in a normal touch, Gridview still can vertically scroll for user to see other thumbnails and continue selecting. There is an ambiguity between 2 types of vertical action, can you help me? Many thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Android how to draw a circle ring as shown in the image.
Sometimes, the problem when your first language is not English is that you don't know how to search on Google. What I mean is that you don't know the right words. When I can't find what I need, but I'm sure there must be something out there, I often use synonyms. In this case, you get what you need if you search for: android custom progress wheel.

Re: [android-developers] How to get more reviews/comments when my app runs mainly in background?
I believe the Rate Us dialog is a good idea. Also, I would add interesting information in that dialog, like some tips, usage statistics, just like some free apps do (e.g. antivirus and protection software normally tell how many threats were blocked).

[android-developers] Re: Choreographer regularly skipping frames during OpenGL Render
Thanks for the response, Doug, but we're talking about two different
things. I'm not referring to the errors that show up the log tagged
Choreographer when the frame warning limit is triggered on the main thread.
I'm talking about actually using the Choreographer API to render OpenGL
content locked to VSYNC. These delays are on the rendering threads. While
I understand frames dropping periodically when the system is servicing
other work, the inability to manage even a few second without skipping
several VSYNC intervals indicates to me that something else is wrong with
the GL code.
Thanks again,
Dave Smith, PE

Bear in mind that anything could be causing main thread delays. It could
be your code. It could be other threads in your app's process. It could
be other apps running on the device. It could be Android itself. It could
be any combination of these things. This is to be expected with
multitasking multiuser operating systems and the wide variety of devices
out there and their hardware capabilities.
The Choreographer itself doesn't start complaining about skipped frames in
logcat until after 30 frames have been skipped:
private static final int SKIPPED_FRAME_WARNING_LIMIT =
SystemProperties.getInt(
debug.choreographer.skipwarning, 30);
So maybe you can lighten up your own acceptable threshold for frames
skipped (unless you're actually observing the jank that you're trying to
avoid)?

Hello all -
I am working on an application that is using Choreographer and OpenGL to
render flash patterns on the display. Our GL calls are quite simple,
simply toggling the display back and forth between white and black using
glClearColor() based on the frame time and status of the pattern we want to
apply. The timing of this pattern if very critical, and I am having severe
issues getting consistent behavior out of the timing pulses we received
from Choreographer to do the rendering.
For simplicity sake, I have basically copied the Basic Dream application
in AOSP, so 95% of my code looks exactly like this sample:
https://android.googlesource.com/platform/packages/screensavers/Basic/+/master
Our only change is that, where they call mSquare.draw() inside of
doFrame(), we have another method called drawFrame() that does the
following:
private void drawFrame() {
final boolean nextBit = mPattern[mIndex];
if (nextBit) {
glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
} else {
glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
}
glClear(GL_COLOR_BUFFER_BIT);
return true;
}
However, for the purposes of this discussion, you can see the *exact
same behavior* by simply running the AOSP sample as an application (i.e.
changing the Colors class from a DreamService to a launcher Activity).
The problem is that on a regular basis (at least once per second, often
many times), the debug logging returns that the frame callback took 33ms
(instead of 16ms), and in many cases 50ms+! I can understand skipping a
rare frame here or there, but skipping 3-4 frames at once seems like I'm
missing something big here. Not all devices do this, but high-end devices
like the Nexus 5 and GS4 do. Devices we've tested like the Note 3, GS3,
and Moto X don't seem to do so nearly as often. Example typical logcat
