Answer 1

The question is rather old, but I had similar problem, so I'll describe what was wrong. Actually, parameters in listItem.measure() are used wrong, you should set something like this:

listItem.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED))

However, be careful with unspecified width measure spec, it will ignore all layout params and even screen dimensions, so to get correct height, first get maximum width View can use and call measure() this way:

listItem.measure(MeasureSpec.makeMeasureSpec(maxWidth, MeasureSpec.AT_MOST), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
