Hi All,
We have developed an application that has some UI with default Android
Progress Bar, some Music Icons like play/pause,Selectors and text views.
Input: we have a layout specified by designer where all values are in
pixels and the original layout is specified for 1080. also the font sizes
are specified in "sp"
also the designer has provided drawables for 1080. we will not be receiving
new set of drawables for 720p.
we have some icons, selectors etc in drawables. only selectors are 9 patch
images.
We need to support both 720p and 1080 resolution as we want this
application in Google Tv Apps.
The given layouts works fine for 1080 resolution but when we change the
resolution to 720p, all the UI gets disturbed.
*
What is the correct approach to support 720p and 1080 resolution?
*We have tried the following options -
1. Option 1
------------------------------
We have created the following two folders -
a) layout- Here the xml files have dimensions specified in "dp", with a
factor of 0.5 with the original pixel value.
px = dp * (dpi /160) . use "dpi" for 1080 = 360
since original layout from designer has values in pixels, we
convert them to dp using above formula
dp = px / ( dpi / 160 ))
Font sizes are specified in "sp"
b) drawable-xhdpi - contains resources given by designer for 1080
Issue: we observe that there is some shift in text view margins, and
font size got reduced.
2. Option 2
------------------------------
we tried by creating a layout for "hdpi" seperately with same set of
drawables. i.e
a) layout-hdpi - here the xml files use a factor of 1.5 on original pixel
values specified by designer, to get dp values
b) drawable-hdpi : same set of original resources are copied here
Issue: the layout gets stretched
3. Option 3
-------------------------------------
we tried adding layout-tvdpi and drawable-tvdpi. layout-tvdpi has xml files
which use a factor of 1.33 on original pixel values
we observed that Google TV did not consider tvdpi at all !!
And, finally we tried with changing all the drawables to 9-patch images. It
helped a little though the issue with text views, as mentioned in the
Option 1, remained though.
Please help. ASAP.
Regards,
Revathi KJ
