有时候我们为了做一个Android平板应用，需要设置一个和平板大小一致的模拟器。但是SDK给出模拟器中只有三星GALAXY TAB，其并不符合我们的要求
所以，我们需要定制我们自己所需要的模拟器。
（1）平板大小最小也是7寸，属于大尺寸屏幕。
所以我们选择屏幕的skin时也要用大屏幕的...在Android 3.0中提供了 WXGA ,
当然你可以使用2.2中的WXGA800也可以。不过需要再设置Resolution为你指定的分辨率x*y
（2）设置屏幕的density （Abstracted LCD Density）
记住这个公式：
DENSITY = sqrt (x^2+y^2)/d
x，y分别为横向和纵向的像素大小. d为屏幕的尺寸
320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

Abstracted LCD Density
So, if you have same number of pixels with more screen density, it's got to be a smaller screen.
The formula is:
DENSITY = sqrt (x^2+y^2)/d where d is the diagonal in inches.
So, supposing you want a d=7", then you need a density of:
Density=sqrt(1280x1280+800*800)/7 = 215'6339
So, fix the ABSTRACTED LCD DENSITY to 216 and there you are.
(3) 注意avd时要 注意scale display to real size 可以调整模拟器在自己屏幕上的大小 ，如果是10寸平板就选10吧。
运行后，模拟器是没有键盘的。 但可以用我们的物理键盘来操作。下面是键盘和模拟器按键映射
