android嵌套layout_weights

Question

I'd like to have the effect of LinearLayout Horizontal inside LinearLayout Vertical. The problem is I want to have layout_weights for Views in the Horizontal layout and layout_weights for the Views in the Vertical one. It works, but in eclipse I get a warning that it's inefficient and that I shouldn't use layout_weights one in another.

This is what I did:

In the horizontal LinearLayout each button got a layout_weight of 1 and in the vertical LinearLayout, each inner View got a certain weight as well.

Is there a way to do this effect in some other way and keep it flexible to look good in all the devices? I don't plan on using GridLayout because I want to support older devices running android.

Answer 1

It is just a warning. If you will not continue to wrap the LinearLayout in another one with weigths and so on, maybe you can ignore this warning. Using layout_weight is bad for performance because AFAIK it will cause each widget to be measured twice, than each widget inside it to be measured again twice and so on.

If you do not see performance issues with your layout, I think you can keep it, because I can`t see other ways to achieve this.

Alternatively, there is also a backward compatible GridLayout if you want to consider using it.
