的LinearLayout layout_weight [英] LinearLayout layout_weight

问题描述

我有一个填充了行一个ListView。这些行来自看起来像一个XML文件：

I have a ListView that is populated with rows. These rows come from an XML file that looks like:

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="8dip"
android:weightSum="100">
<TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:id="@+id/columnA"
    android:layout_weight="30"
    android:layout_gravity="center"/>  
<TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:id="@+id/columnB" 
    android:layout_weight="30"
    android:layout_gravity="center"/>
<ImageView 
    android:layout_width="0dp" 
    android:layout_height="wrap_content" 
    android:src="@drawable/icon" 
    android:id="@+id/columnC"
    android:layout_weight="10"
    android:layout_gravity="center"
    >
</ImageView>       
<CheckBox
    android:layout_width="0dp"
    android:layout_height="wrap_content" 
    android:id="@+id/columnD"
    android:layout_weight="30"
    android:layout_gravity="center"/>

问题是我想要的columnC项目，columnB项目非常接近，所以我行三部分等距出来，即：columnA，（columnB + columnC），然后columnD。我试图做到这一点通过layout_weight正如你所看到的，但是上面的code似乎产生相反的效果。 columnA和columnB左侧非常压扁，C列似乎本身就是一个大空间中漂浮，然后columnD靠近columnC，与右太多空间。我究竟做错了什么？ ：■

The problem is that I want the columnC item and columnB item to be very close together, so that my rows are equally spaced out in three parts, i.e.: columnA, (columnB+columnC) and then columnD. I tried to achieve this by using layout_weight as you can see, however the above code seems to have the opposite effect. columnA and columnB are very squished on the left, column C seems to be floating in a large space on its own, and then columnD is located close to columnC, with too much space on its right. What am I doing wrong? :s

推荐答案

我想你想columnC和columnB具有相同的重量，但你有它设置与他们不同。

I would think that you want columnC and columnB to have the same weight, but you have it set with them different.

尝试

columnA：体重= 2

columnA:weight=2

columnB：体重= 1

columnB:weight=1

columnC：体重= 1

columnC:weight=1

columnD：体重= 2

columnD:weight=2

我与权重属性的经验非常有限，但我认为这是你可以得到你想要的结果。

I have very limited experience with the weight attribute but I think this is how you can get your desired result.
