How to force android choose the right layout for the screen sizes supported?

Question

I'm trying to support all kind of screens on my project. I added the the respective graphics in the folders-drawables(ldpi,mdpi,Hdpi,xhdpi,xxhdpi),, And also the layouts folders(layout-small,layout,layout-large,layout-xlarge,layout-xxlarge). Here is the thing: When I open the app on the emulator,on a normal screen(mdpi),.everythings is right, But when I choose other emulator like one Hdpi/large,.the android system is not choosing the right graphics.(for example I open a Hdpi emulator and the system is choosing the normal graphics(mdpi).

What do I need to do?,do I need to write some code to force the system choose the right graphics ?,really needing help !

Answer 1

You should be changing the dpi values between every view type so they look appropriate in each view. On the webpage Supporting Multiple Screens, there is a chart that displays the minimum screen sizes for the different screens. You will have to do some algebra to compare each of the values so you can translate an image's dpi from one size to another. However, another solution is to use "match_parent" and "wrap_content" as opposed to using defined sizes, as it simplifies the process. The same process applies to sp for text in the views.

The chart I am referring to is the one that looks like this:

• xlarge screens are at least 960dp x 720dp

• large screens are at least 640dp x 480dp

• normal screens are at least 470dp x 320dp

• small screens are at least 426dp x 320dp

EDIT: I also forgot to mention that if you use multiple views in a LinearLayout, you can use the android property called android:layout_weight to use a ratio to divide up the screen.

EDIT: Then perhaps the problem is that you don't have your images scaled properly. Maybe you should try adding these to your ImageViews:

android:adjustViewBounds="true"
android:scaleType="fitXY"
