Answer 1

You can define multi dimen files, and add dimensions of each view according to screen size in there. You can find detailed answer here

A set of six generalized densities:

• ldpi (low) ~120dpi
• mdpi (medium) ~160dpi
• hdpi (high) ~240dpi
• xhdpi (extra-high) ~320dpi
• xxhdpi (extra-extra-high) ~480dpi
• xxxhdpi (extra-extra-extra-high) ~640dpi

Here is the official docs

Answer 2

Well that depends on your code

1. Dont use Static values
2. Try to use Wrap content
3. Use Relative and Linear Layout Depends on your Requirement
4. For Drawables Use every DPI Folder

Answer 3

If you want to use single layout and that should support all the screens like ldpi, , mdpi, hdpi, x-hdpi, xx-hdpi then you have to use weight in your layout that will handle screen size for all the screens.

Here’re a few things:

If you want to divide the space equally between Views with the same weight – set 0dp as Views’ width.
If you set View width to wrap_content – size of the Views will depend on weight and content inside each View.

Answer 4

Create three different Layouts Folder in your res folder for all devices and use the dimensions accordingly.

Generic Layout Folders

res/layout-small
res/layout-normal
res/layout-large
res/layout-xlarge

After you are done with making your Normal/Medium Layouts follow these steps:

1. Convert the Normal Dimensions for other Screen Sizes.
2. Copy your Normal Layout xml files in to other Folders.
3. Change the suffix of the dimensions used according to the folder that you are in
4. Resize the Image Resources in your drawable folder (Width and Height - Same technique as we used for converting the dimens) and put them in their respective drawable folder (drawable-ldpi, drawable-mdpi, drawable-hdpi, drawable-xdpi and so on).
5. Then your Layouts should work on every device with correct positioning.

For converting Values

0.75 - ldpi  (small)   //mdpi dimens *0.75
1.0  - mdpi  (normal)  //First create these dimensions
1.5  - hdpi  (large)   //mdpi dimens *1.5
2.0  - xhdpi (xLarge)  //mdpi dimens *2.0

For Example

android:layout_width="66dip" //in normal
android:layout_width="100dip"//in large 66*1.5=100(approx)
android:layout_width="52dip" //in small 66*0.75=52(approx)

Also new Qualifier has been introduced - SmallestWidth - AvailableScreenWidth - AvailableScreenHeight

I hope this helps.

Answer 5

May be you can try below library which manages all the screen size resolution automatically.

compile 'com.intuit.sdp:sdp-android:1.0.4'

You need to just add the dependency in your build.gradle file and you are done.

You need to specify like:

android:layout_height="@dimen/_10sdp"

Instead of usual:

android:layout_height="@dimen/10dp"

Answer 6

There are three ways to do this :

1) Put your images and icon in different drawable folder including drawable-mdpi , drawable-hdpi , drawable-xhdpi , drawable-xxhdpi , drawable-xxxhdpi which will be access image from particular folder based on screen resolutions. Don't apply fixed values everywhere for image. Fixed dimensions can be vary with different device and image will be looked stretch. So use wrap_content

2) Set dimensions in dimens.xml for different values folder.

values-mdpi\dimens.xml
values-hdpi\dimens.xml
values-xhdpi\dimens.xml
values-xxhdpi\dimens.xml
values-xxxhdpi\dimens.xml

3) Use LinearLayout with proper using of android:layout_weight.
