支持不同android屏幕尺寸和密度的技术

Question

I am creating an android app and I want to be able to support as many android devices as possible that use Android 4.4 and above. The screen sizes that I want to support are:

• Normal
• Large
• xLarge

I have created different dimens.xml files for each size. My first question is, the numbers that I put in each dimens.xml file should be based on the minimum dimension of each category? For example: for normal I should design the layout in a device with dimension 470dp x 320dp, for large a device with dimensions 640dp x 480dp and for xlarge a device with dimensions 960dp x 720dp ?

My second questions is, let's say that we have our base dimension files for normal, large and xlarge, how many more dimension xml files should I create in order to support different densities too. Also do devices with Android 4.4 and above support all densities or are some excluded? (for example LDPI)

Now let's say that I exclude the LDPI density, should I make each density for each size or if I make one MDPI for each screen size and one HDPI for each screen size everything will "look" the way I want them, even in devices with XXXHDPI density?

One last thing, if you can recommend any devices to make my "base" layout that would be great.

Answer 1

hi you can handle size of different resolutions by this,

create different types of values folder.Create these folder inside res.

values-hdpi

values-xhdpi

values-xxhdpi

values-xxxhdpi

and dimens.xml create accordingly for different resolutions.Use all padding and margin from here.

This is way to handle different resolutions for different sizes.
