如何在运行时为按钮添加边距? [英] How to add margin to a Button at run time?

问题描述

我必须在LinearLayout上添加多个按钮.但是我想把那些按钮说成5px.我找不到设置Button的边距的方法.有什么主意吗?

I have to add more than one buttons on a LinearLayout. But I want to put those buttons say 5px apart. I could not find a way to set a margin of a Button. Any idea?

推荐答案

使用按钮元素的layout_margin属性.那行不通吗?

Use the layout_margin property of the button element. Does that not work?

<Button android:layout_margin="5px" (...)/>

编辑

在Java中创建按钮时，LayoutParams用于指定边距，等等.

Edit

When creating a button in java, LayoutParams is used to specify margins and so.

Button button = new Button();
(....)
params = new LinearLayout.LayoutParams();
params.leftMargin = 5;
(set params as you need)
parent.addView(button, params);

您使用的LayoutParams必须与添加按钮的布局匹配(请参见 http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html ).对于LinearLayout，请使用LinearLayout.LayoutParams并相应地设置* Margin字段.

The LayoutParams you use must match the Layout you add your button in (see http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html). For a LinearLayout, use a LinearLayout.LayoutParams and set the *Margin fields accordingly.
