imagebutton for different screen size

Question

I have a problem with supporting screen size for ImageButton.
when adding ImageButton the image is much bigger than the screen size and half of it is outside the screen limit.
I tried by changing the size for every image, but in (4 inches screen size) the image appears smaller than other screens size .

is there any way I can make from xml, not to add many differet size to dpi folder

Hopefully someone can help.
thanks a lot

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

   android:paddingBottom="@dimen/activity_vertical_margin"
   android:paddingLeft="@dimen/activity_horizontal_margin"
   android:paddingRight="@dimen/activity_horizontal_margin"

这就是为什么制作了不同的dpi文件夹，以便图像每次在不同的屏幕上都会更改大小的原因。.确保将其放在图像的右侧文件夹中。
