Re: [android-developers] Android devices and use of MM/INCH
You're right... This is the config of DisplayMetrics of One X: xdpi = 240 widthPixels = 480 We can deduce that the screen have a width of 2 inches... but in real - 2,25 inches So, is there a solution to determine this automatically? Or is it impossible to have real mesure on all devices?

For instance, LG P500 states it has a 160 dpi screen but if you measure the screen and do the maths, it's actually 180 dpi. Correspondingly, if you compute your pixel sizes based on the 160 dpi figure to get a specified physical size (in mm), it will come out smaller. I'd compute the actual DPI One X and Wildfire have and compare that to figures in DisplayMetrics. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: ViewPager and setClipChildren(false)
Exactly! Thanks Dave!
Le mercredi 29 août 2012 01:45:11 UTC+2, Dave Smith a écrit :
Thesalan -
Calling setLayerType() on just the View will work, but you have to do it
on the correct view. In this case, the issue that doesn't work with
hardware acceleration is the parent ViewGroup clipping its children, so the
PagerContainer in the example is the view that you need to call it on, not
the ViewPager itself. If you modify PagerContainer.java in the gist like
so:
private void init() {
setClipChildren(false);
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
You should be able to enable hardware acceleration in your manifest and
the pager code will still work as expected. I will update the gist example
when I have a spare moment with some discussion, and I have starred the
issue Mark created (you should do the same).
Cheers,
Dave Smith

Hi!

The ViewPager here is just on Item4, and with setClipChildren(false) we
can see the other item.
This works greats on emulator (tested on API 7 to 16) and some devices!
But I encounter some problems on more recent devices, like HTC One X
(Android 4.0.4) and a Nexus S (CM10 - Android 4.1.1) : the ViewPager
doesn't really extended! Just the current item is shown, and when you are
sliding, the next item is shown :

Anybody else already encounter this problem? I think is an optimization
on these devices, but how can I bypass this?
Thanks in advance!

Re: [android-developers] ViewPager and setClipChildren(false)
Mark, a huge thank you!! I never thought the problem would come from hardware acceleration (I'm a beginner after all ^_^). Indeed, my current rom force hardware acceleration for all applications. I tried to force software mode just on the ViewPager with setLayerType(View.LAYER_TYPE_SOFTWARE, null) (see here : http://developer.android.com/guide/topics/graphics/hardware-accel.html) but it doesn't work : content stay inside the viewpager. But by specifying it in the manifest as you say it works very well! And given the application, it does not pose any problems to do without hardware acceleration. Again, thank you very much Mark!

Since the issues of clipping and hardware acceleration are beyond my area of expertise, I can't explain why this is the case. Rather than disable hardware acceleration for the whole activity, you could experiment with disabling it just for the ViewPager itself.
