网格布局列宽 [英] GridLayout Column width

问题描述

我在网​​格布局 2列。我想要做的就是让那些列占据半个屏幕宽度的每一个，然后让其子的内容填充自己的细胞宽度/高度。我试着设置孩子 FILL_PARENT 但这只是导致第一个接管整个布局。它似乎网格布局不支持重量？也许有一个更好的布局使用，但我希望有一个网格式的布局，这样似乎是一个自然的选择。

I have 2 columns in my GridLayout. What I want to do is make those columns take up half of the width of the screen each and then have its child contents fill their own cells width/height. I tried setting the children to fill_parent but that just causes the first one to take over the entire layout. And it seems GridLayout doesn't support weight? Maybe there is a better layout to use, but I want a Grid style layout so that seems like the natural choice.

我有一段简单的code显示4个按钮中的2列需要的可用空间的50％的网格布局： 也许它可以帮助

I have a simple piece of code to show 4 buttons in a gridLayout of 2 columns that take 50% of the available space: perhaps it can help

<GridLayout
    android:id="@+id/grid"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:columnCount="2"
    >


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_gravity="fill"
        android:layout_columnWeight="1"
        />

       <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_gravity="fill"
        android:layout_columnWeight="1"
        />

       <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_gravity="fill"
        android:layout_columnWeight="1"
        />

       <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_gravity="fill"
        android:layout_columnWeight="1"
        />



</GridLayout>

解决方案也许是这样的：

Solution is perhaps this :

    android:layout_gravity="fill"
    android:layout_columnWeight="1"
