安卓：设置权重参数编程做了什么，我想的相反 [英] Android: Setting the Weight parameter programmatically does the opposite of what i want

问题描述

我在使用Android的一个问题。 我设置在Java中的权重参数，但它究竟在做什么，我想要的oposite。

i'm having a problem with android. I'm setting the Weight parameter in Java, but it's doing exactly the oposite of what i want.

这里的code

LinearLayout container = new LinearLayout(context);
// some code ...
container.setWeightSum(1f);

View v1 = new View(context);
v1.setBackgroundColor(Color.parseColor("#ff0000"));
LinearLayout.LayoutParams p1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
p1.weight=0.1f;

View v2 = new View(context);
v2.setBackgroundColor(Color.parseColor("#000000"));
LinearLayout.LayoutParams p2 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
p2.weight=0.9f;

container.addView(v1,p1);
container.addView(v2,p2);

我重复这个过程7次，将容器布局之间的黑线。 通常情况下，我应该得到一个小红柱在LEF，和大黑的，但这里是我这个code得到：

I repeat this process 7 times with adding a black line between the container layout. Normally i should get a small red column on the lef, and a large black one, but here's what i get with this code :

它为什么这样做完全的code相反？

Why does it doing exactly the opposite of the code ?

感谢您的帮助球员。

推荐答案

当我们使用wieght宽度应该是零

When we use the wieght width should be Zero

尝试用宽度为0的容器内儿童.............

try with width 0 for with children inside the container.............

 LinearLayout.LayoutParams p1 = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.WRAP_CONTENT);



LinearLayout.LayoutParams p2 = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.WRAP_CONTENT);
