Android screen size resolution

问题:

My app works perfectly in resolution 480x800. If I keep the 480x800 resolution but change the screen size to for example 2.7 inches, 3.7 inches or 5.4 inches it still is perfect. But when I change the resolution to for example 640x1066 all the ImageButtons is too small and in the wrong place in all screen sizes... I have created ImageButtons in all four folders(drawable-l, m, h, xh) but still the buttons is not in the correct size..

<ImageButton
android:id="@+id/ib1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="6dp"
android:layout_marginTop="433dp"
android:background="@drawable/imagebutton1" />

<ImageButton
android:id="@+id/ib2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="188dp"
android:layout_marginTop="436dp"
android:background="@drawable/imagebutton2" />

NOTE: My problem is not when I change screen size, but when I change screen resolution.

I would really like to see some code.

If you use RelativeLayout with attributes like android:layout_width and android:layout_height and specify values in dp (density pixels) e.g. android:layout_height="40dp" it should work just fine.

Please try to share some code with us.

Make sure that your assets that you have in your ldpi, mdpi, hdpi and xhdpi folders are scaled correctly to accommodate the diff. resolutions. I accidentally scaled some assets incorrectly, and although they were in the correct folders..gave me some bad results
