如何在7英寸台式机和10英寸平板电脑上运行Android应用

Question

I am creating an app for both a 10-inch and a 7-inch tablet.

My problem is, on the 10 inch tablet it's not working well. On the 7-inch one it is. I copied small images in the hdpi folder and big images in the xhdpi folder. I tried using below way but I am getting a problem on 10-inch tablets. Here images looking small like that. I thought the 10 inch tablet was also taking hdpi folder images. The app is in landscape mode.

How to make this app for both tablets?

XML files:

res/layout-large/main.xml  -----7 inch
res/layout-xlarge/main.xml  -----10 inch

Images:

res/drawable/hdpi---7 inch images
res/drawable/xhdpi---10 inch images

Table dimensions 7 inch:

1024 to 600
density 240
ramsize 512
version 3.0

Table dimentions 10 inch:

1280 to 800
density 160
ramsize 512
version 3.0

Answer 1

You've got to use the new qualifiers at the bottom of http://developer.android.com/guide/practices/screens_support.html

For example

res/layout/main_activity.xml           # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger) 
res/layout-sw720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)

Answer 2

HDPI is for density ~= 240
XHDPI is for density ~= 300

Your 10 inch tablet is density 160, which is MDPI.

Also LARGE & XLARGE depends on the screen size (resolution), but your drawable folders depend on the screen density, which is not the same thing.
