How to change Width of Android's Switch track?
提问by NeilDA
I'm going crazy with this tiny problem. I have a 'switch' Form widget, but no matter how much I try, I cannot make it narrower. Even if I have one character instead of 'ON' or 'OFF', the size of switch remains the same. The 'thumb' becomes small, but it has to be dragged over the same distance as before. Changing the 'layout_width' to a smaller value simply cuts off the remaining track. 'minWidth' doesnt seem to do anything.
我快被这个小问题搞疯了。我有一个“切换”表单小部件，但无论我尝试多少次，都无法将其缩小。即使我有一个字符而不是“ON”或“OFF”，开关的大小也保持不变。“拇指”变小，但必须像以前一样拖动它。将 'layout_width' 更改为较小的值只会切断剩余的轨道。'minWidth' 似乎没有做任何事情。
Anybody knows how I can do this? Ideally I want just an empty thumb and I'll colour code both thumb to know which is which.
有谁知道我怎么能做到这一点？理想情况下，我只想要一个空拇指，我会对两个拇指进行颜色编码，以知道哪个是哪个。

Here is my solution. I removed the texts, set the padding of the track and define the switchMinWidth prop. This is my xml:
这是我的解决方案。我删除了文本，设置了轨道的填充并定义了 switchMinWidth 道具。这是我的 xml：
<Switch
android:id="@+id/theSwitchId"
android:textOn=""
android:textOff=""
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:thumbTextPadding="5dp"
android:switchMinWidth="40dp"
android:layout_gravity="right|center_vertical" />
Hope it helps somebody.

You should use android:trackinstead of android:thumb.
您应该使用android:track而不是android:thumb.
All my code:
我所有的代码：
<Switch
android:id="@+id/switch_security_tog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="16dp"
android:background="@color/transparent"
android:button="@null"
android:textOff=""
android:textOn=""
android:thumb="@null"
android:switchMinWidth="56dp"
android:track="@drawable/thumb" />
