androidviewgroup

custom ViewGroup example?

I searched here on SO, on Google, on the android docs...

But I cannot find a single snippet of code with a example of custom viewgroup, I find at most some vague explanations...

Can someone provide one? How you make a viewgroup where you can put its children where you want?

Solution

  • I think the simplest example to look at is the source for AbsoluteLayout.java

    https://github.com/android/platform_frameworks_base/blob/master/core/java/android/widget/AbsoluteLayout.java

    You need to override onMeasure to measure the children and onLayout to position them.

    I have strikingly more complicated ViewGroup code I can share as well if you want.
