获取视图的边距

发布于 2024-12-05 04:27:02 字数 336 浏览 0 评论 0原文

如何从活动中获取视图的边距值？视图可以是任何类型。

经过一番搜索后，我找到了填充视图的方法，但在 Margin 上找不到任何内容。有人可以帮忙吗？

我尝试了类似的方法，

ViewGroup.LayoutParams vlp = view.getLayoutParams();
int marginBottom = ((LinearLayout.LayoutParams) vlp).bottomMargin;

这有效，但在上面的代码中我假设视图是 LinearLayout。但即使我不知道视图类型，我也需要获取 margin 属性。

How can I get the margin value of a View from an Activity? The View can be of any type.

After a bit of searching I found out ways to get padding of a view, but couldn't find anything on Margin. Can anyone help?

I tried something like this,

ViewGroup.LayoutParams vlp = view.getLayoutParams();
int marginBottom = ((LinearLayout.LayoutParams) vlp).bottomMargin;

This works, but in the above code I have assumed the view to be a LinearLayout. But I need to get the margin attribute even when I don't know the view type.

试试这个：

View view = findViewById(...) //or however you need it
LayoutParams lp = (LayoutParams) view.getLayoutParams();

边距可以通过

lp.leftMargin;
lp.rightMargin;
lp.topMargin;
lp.bottomMargin;

编辑： 访问
也许 ViewGroup.MarginLayoutParams 适合您。它是其他 LayoutParams 的基类。

ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

http://developer.android.com/reference/android/view/ViewGroup .MarginLayoutParams.html

try this:

View view = findViewById(...) //or however you need it
LayoutParams lp = (LayoutParams) view.getLayoutParams();

margins are accessible via

lp.leftMargin;
lp.rightMargin;
lp.topMargin;
lp.bottomMargin;

edit:
perhaps ViewGroup.MarginLayoutParams will work for you. It's a base class for other LayoutParams.

ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

尝试

ViewGroup.MarginLayoutParams vlp = (MarginLayoutParams) view.getLayoutParams()

vlp.rightMargin
vlp.bottomMargin
vlp.leftMargin
vlp.topMargin

这个至少为我的视图返回了正确的边距。

Try

ViewGroup.MarginLayoutParams vlp = (MarginLayoutParams) view.getLayoutParams()

vlp.rightMargin
vlp.bottomMargin
vlp.leftMargin
vlp.topMargin

This returned the correct margains for my view atleast.

现在使用这个编辑过的代码。这会帮助你

FrameLayout.LayoutParams lp=(FrameLayout.LayoutParams)mainLayout.getLayoutParams();

lp.leftMargin  // for left margin
lp.rightMargin   // for right margin

now use this edited code. this will help you

FrameLayout.LayoutParams lp=(FrameLayout.LayoutParams)mainLayout.getLayoutParams();

lp.leftMargin  // for left margin
lp.rightMargin   // for right margin

正如其他人所建议的，layout_margin#是父级的#边缘和您的视图之间的空间。

# 替换“左”、“右”、“上”或“下”

获取/设置边距对我有用：

ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) mView.getLayoutParams();
params.topMargin += 20;
mView.requestLayout();

当然，我的视图确实是一个 ViewGroup，父级也是一个 ViewGroup。在大多数情况下，您应该将布局参数转换为父级的 View 类 LayoutParams（在本例中为 ViewGroup 和relativelayout）

As others suggested, layout_margin# is the space between the parent's # edge and your view.

# replaces "Left", "Right", "Top" or "Bottom"

Getting/setting margins worked for me with:

ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) mView.getLayoutParams();
params.topMargin += 20;
mView.requestLayout();

Of course, my View was indeed a ViewGroup and the parent was a ViewGroup as well. In most cases, you should cast your layout params to the parent's View class LayoutParams (in this case it's ViewGroup and RelativeLayout)
