Android Dashboard Icon size

Question

I am developing a little application in android by following the Android UI Patterns and I am facing a little difficulty about the patterns used to build the dashboard. My question is the following : what should be the size of the icons used to build dashboard according to differents densities. In the android SDK documentation, it is not described.

King Regards.

Answer 1

If it helps, reference the DashbordLayout class in the Google I/O schedule app at http://code.google.com/p/iosched The class itself is in src/com/google/android/apps/iosched/ui/widget/DashboardLayout.java

An example of how it's used is seen in:

• res/layout/fragment_dashboard.xml for the dashboard itself and the buttons inside. Note the style attribute set
• res/values/styles.xml for an example of the style used
• res/values/dimens.xml for an example
• res/values/colors.xml for the color they used (obviously you can use any)
• res/drawable/home_btn_*.xml for examples of a selector related to the various states of the button to reference different drawable files
• res/drawable-hdpi/home_btn_*.png for the actual png files that are used, which tend to be 144x96

I myself had no idea so much was involved to make it look just right, but this made things so much easier once I saw how to properly make it.
