Question

It s just freaking me out, but I can t make my layout depend on weight. There are two relative layouts and two linear layouts and some elements in both of these layouts. I ve put android:layout_weight="0.2 to the first one, android:layout_weight="0.1 to the second one, android:layout_weight="0.5 to the third one, and android:layout_weight="0.2 to the last one. The sum is 1, right? But it doesn t work. I m afraid, it s because of different layout_height and maybe different categories of layouts? The XML-code is here

Answer 1

My experience with the layout_weight attribute is the following: Set all layout_height (or width depends on what you are doing) to fill_parent or wrap_content (it should be the same value for all elements). Try both versions. Sometimes wrap_content is better sometimes fill_parent is better.

There are many theories about the mystic of the layout_weight attribute. This is my version^^

Edit(以英语发言):我想提的是,逻辑被歪曲:这个要素的重量越低。

Answer 2

我曾经历过,确定宽度或高度(取决于你想要达到什么方向,你们的布局跨度)到零,可能不时有用。

如果你使用“0.4f”值,则可能有必要使用“0.4f”值;

You could also try setting the weight_sum to an amount (in your example it could be 10) and then use the layout_weight values 2, 1, 5 and 2 - but I m not sure that it will make a difference.
