Try following scenario of layout. I found at http://jamil.fluidsoul.net/2011/03/06/creating-android-applications-for-multiple-screen-sizes.

Low density Small screens QVGA 240x320 (120dpi):

layout-small-ldpi (240x320)  
layout-small-land-ldpi (320x240)

Low density Normal screens WVGA400 240x400 (x432) (120dpi):

layout-ldpi  (240 x 400 )
layout-land-ldpi  (400 x 240 )

Medium density Normal screens HVGA 320x480 (160dpi):

layout-mdpi (320 x 480 )
layout-land-mdpi (480 x 320 )

Medium density Large screens HVGA 320x480 (160dpi):

layout-large-mdpi (320 x 480 )
layout-large-land-mdpi (480 x 320)

Galaxy Tab ( 240 dpi ):

layout-large  (600 x 1024) 
layout-large-land  (1024 x 600)

High density Normal screens WVGA800 480x800 (x854) (240 dpi):

layout-hdpi (480 x 800)
layout-land-hdpi (800 x 480)

Xoom (medium density large but 1280x800 res) (160 dpi):

layout-xlarge (800 x 1280)
layout-xlarge-land (1280 x 800)

If outcome display in Graphical layout best matches with all other, you will get same output in original device also.

you should. If view display is different what you want. Otherwise there is also other way you can find at http://stackoverflow.com/questions/14108074/layouts-on-different-models-of-mobiles/14108211#14108211 – Chintan Rathod Mar 12 '13 at 07:09
i have created layout,layout-normal,layout-large..but still its not working,i have to put the same layout for every screen right – Mar 12 '13 at 07:15
as per your question, you should have 2 layout like layout-small and layout. Two are sufficient to do all work. If not working, something goes wrong in your code because I use this scenario in my application and it works fine for me. – Chintan Rathod Mar 12 '13 at 07:19
i have one doubt that i can use the same layout for each and every layout folder.. – Mar 12 '13 at 07:24
depends. If its normal screen, you can. But I faced problem in large and xlarge screen due to more resolutions and screen sized then normal and small screen. – Chintan Rathod Mar 12 '13 at 08:22
@ranjith thanks for update.. Might be domain is no more exist. Answer was posted 2 years back.. :( – Chintan Rathod Aug 07 '15 at 07:44

For detail, please refer to Android Developer Guide.

To summarize, you must declare each supporting screen sizes in your AndroidManifest.xml. For example, you have to include the following:

<supports-screens android:resizeable=["true"| "false"]
                  android:smallScreens=["true" | "false"]
                  android:normalScreens=["true" | "false"]
                  android:largeScreens=["true" | "false"]
                  android:xlargeScreens=["true" | "false"]
                  android:anyDensity=["true" | "false"]
                  android:requiresSmallestWidthDp="integer"
                  android:compatibleWidthLimitDp="integer"
                  android:largestWidthLimitDp="integer"/>

To support 240*320, you must do the following:

1: In AndroidManifest.xml, include

<supports-screens android:smallScreens="true" />

2: Create different layout-small folder:

res/layout/layout-small/

3: Create drawable-ldpi folder (you already did):

res/drawable-ldpi/

though i have used the layout,layout small it does not make any change — , Mar 12 '13 at 06:55
