将背景放置在线性布局上，几乎占据了整个屏幕的3/4 [英] Putting a background on the linear layout and takes almost 3/4 of the screen

问题描述

我尝试了其他帖子提供的各种帮助(将宽度设置为0dp等)，但似乎无济于事.

I have tried all kinds of help from other posts (setting widths to 0dp etc.) but nothing seems to work.

我有2种布局，第一种布局似乎仍然占主导地位.如果我将背景色放在文本视图上，则它们的行为会正确并正确结束.但是在线性布局上放一个背景，它几乎是屏幕的3/4！?

I have 2 layouts and the first one still seems to dominate. If I put background colors on the textviews, they are behaving themselves and end correctly. However put a background on the linear layout and it is almost 3/4 of the screen!?

推荐答案

执行以下操作.你可以解决你的问题.

Do the following things. U can solve your problem.

• 将孩子的android:layout_width设置为"0dp"
• 设置父级的android:weightSum
• 按比例设置每个孩子的android:layout_weight(例如weightSum = "5"，三个孩子:layout_weight="1", layout_weight="3", layout_weight="1")

• set the android:layout_width of the children to "0dp"
• set the android:weightSum of the parent
• set the android:layout_weight of each child proportionally (e.g. weightSum = "5", three children: layout_weight="1", layout_weight="3", layout_weight="1")
