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
