如何在LinearLayout子项之间腾出空间? [英] How to make space between LinearLayout children?

问题描述

我正在以编程方式将自定义视图添加到垂直的LinearLayout中，并且我希望这些视图之间有一定的空间.我尝试将setPadding(0，1，0，1)添加到我的CustomView构造函数中，但这似乎没有任何效果.有什么建议吗?

I am programatically adding custom views to a vertical LinearLayout, and I would like there to be some space between the views. I have tried adding: setPadding(0, 1, 0, 1) to my CustomView constructor, but this doesn't seem to have any effect. Any advice?

*有人指出，我应该使用页边距.由于我是动态添加视图，因此需要从代码中设置边距(不在xml中).我相信下面是执行此操作的方法，但是它不起作用.

*It was pointed out that I should use margins. Since I am dynamically adding views, I need to set the margins from code (not in xml). I believe the way to do this is below, but it isn't working.

public class MyView extends View
{
    public MyView (Context context)
    {
        super(context);

        MarginLayoutParams params = new MarginLayoutParams(LayoutParams.WRAP_CONTENT,  LayoutParams.WRAP_CONTENT);
        params.setMargins(0, 10, 0, 10);
        setLayoutParams(params);

*编辑.我还在将视图添加到线性布局时尝试使用MarginLayoutParams作为参数(如下所示).这也行不通:

*Edit. I also tried using MarginLayoutParams as a parameter while adding the views to the Linear layout (as below). This also did not work:

MarginLayoutParams params = new MarginLayoutParams(linearLayout.getLayoutParams());
linearLayout.setMargins(0, 10, 0, 10);
linearLayout.addView(view, params);

推荐答案

您应该在子级上android:layout_margin<Side>.填充是内部的.

You should android:layout_margin<Side> on the children. Padding is internal.
