问题
I would like to place a button on top of my google map, which is pretty easy. However I would like it to look like the buttons google uses (zoom buttons, locate me button). Is there a way I can 'cheat' and find the styles they used for their buttons. Or has anyone else created this style before?
回答1:
If you disassemble Google Play Services apk by using apktool, and look into drawable* folders, you will find the resources for these buttons among other resources.
For example, this is the drawable of the upper zoom button:res/drawable/maps_btn_zoom_up.xml, and this is the "empty" button: res/drawable/maps_btn_standalone.xml. Looking at them, it is a lot easier to match their style.
The apk will probably be named like com.google.android.gms-#.apk, where # is some number; you can snatch it from a device which has Google Play Services installed by using adb pull command, it doesn't even require rooting if you know the exact file name.
Update
Here is the archive with relevant resources for the empty standalone button, obtained by this way.

And some numbers:
Button height and width is 38dp
Shadow padding: top 1.5dp
bottom 2.5dp
side 2dp
The background image is NOT nine-patch, but it's pretty easy to create one if you need.

I made this 9-patch image to use as background for the view that you want to be like a google maps button:
The color of the button content is #666666.
Here is an example of a custom view that looks like a google maps button using that background and that color for the text:
回答3:
The button is a 70% semi-transparant white.
Or in HEX, #B3FFFFFF

I was looking for the same thing, and found this question:Change zoom controls in a MapView
It appears a button is 2 images, a normal state and a clicked state. For your purposes, you'd need to style the button yourself / 'cheat' the system. You can get a good template from either the google play lib or the support library.
