Android - 复选框和文本之间的间距 [英] Android - Spacing between CheckBox and text

问题描述

有一个简单的方法可以在CheckBox控件中的复选框和相关文本之间添加填充？

Is there an easy way to add padding between the checkbox in a CheckBox control, and the associated text?

我不能只添加前导空格，多行。

I cannot just add leading spaces, because my label is multi-line.

按原样，文本太靠近复选框：

As-is, the text is way too close to the checkbox:

推荐答案

我讨厌回答自己的问题，这种情况我想我需要。检查后，@Falmarri是在正确的轨道与他的答案。问题是Android的CheckBox控件已经使用了android：paddingLeft属性来获取文本。

I hate to answer my own question, but in this case I think I need to. After checking it out, @Falmarri was on the right track with his answer. The problem is that Android's CheckBox control already uses the android:paddingLeft property to get the text where it is.

红线表示整个CheckBox的paddingLeft偏移值

The red line shows the paddingLeft offset value of the entire CheckBox

如果我只是覆盖了我的XML布局中的填充，它弄乱了布局。以下是设置paddingLeft =0的操作：

If I just override that padding in my XML layout, it messes up the layout. Here's what setting paddingLeft="0" does:

原因是您无法使用XML解决此问题。你在代码中做到了。这是我的代码段，硬编码填充增加了10dp。

Turns out you can't fix this in XML. You have do it in code. Here's my snippet with a hardcoded padding increase of 10dp.

final float scale = this.getResources().getDisplayMetrics().density;
checkBox.setPadding(checkBox.getPaddingLeft() + (int)(10.0f * scale + 0.5f),
        checkBox.getPaddingTop(),
        checkBox.getPaddingRight(),
        checkBox.getPaddingBottom());

这将给出以下内容，其中绿线是填充增加。这比硬编码值更安全，因为不同的设备可以使用不同的可绘制的复选框。

This gives you the following, where the green line is the increase in padding. This is safer than hardcoding a value, since different devices could use different drawables for the checkbox.

更新 - 正如人们最近在下面的答案中提到的，这种行为在Jelly Bean中已经改变了。您的应用程序需要检查其运行的版本，并使用适当的方法。

UPDATE - As people have recently mentioned in answers below, this behavior has apparently changed in Jelly Bean (4.2). Your app will need to check which version its running on, and use the appropriate method.
