的LinearLayout,RelativeLayout的,等如预期利润率不工作 [英] LinearLayout, RelativeLayout, etc. margins do not work as expected
问题描述
好像在组布局边距不工作。
Margins in group layouts do not seem to work.
例如,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="40dip"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/button"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="I'm a button" />
</LinearLayout>
应显示在各方面40P利润率按钮。然而,它有80P边距在右侧和底部。
should display a button with 40p margins on all sides. However, it has 80p margins on the right and bottom.
我是不是做错了什么? 这是一个错误?
Am I doing something wrong? Is this a bug?
一个解决方法是利用重力,但这仅适用于甚至利润。
A workaround would be to use gravity, but this only works with even margins.
顺便说一句,有一个类似的问题<一href="http://stackoverflow.com/questions/1818633/relativelayout-margins-inside-a-listview-are-not-displayed">posted这里但一直没有得到答复。
BTW, there is a similar question posted here but has not been answered.
推荐答案
安卓填充=40dp
上的LinearLayout或安卓layout_margin =40dp
上的按钮会给你你想要的效果。填充限定次边缘和其内容之间的空间,布局定义裕度上的视图的侧面额外空间。
android:padding="40dp"
on the LinearLayout or android:layout_margin="40dp"
on the Button will give you the effect you want. Padding defines the space between a views edges and its content, layout margin defines extra space on the sides of a view.
