Google Maps API location button (Android Studio) Not Displayed
I am developing a native Android application, with the Android Studio IDE, which performs an integration with the Google Maps API.
I noticed in several videos that when activating the setmylocation property (True) should activate the location button (top Direct corner of activity), but when I activate this property the button is not being displayed. I have tried several ways to solve the error, but I still did not find the solution.
Details:
- I am inheriting the SupportMapFragment class.
- I use Google'S location API to pick up location.
- every part of the location is working properly, the only problem is this button that is not displayed.
Source Codes:

map activity (the setMyLocation (true) property is called in the onmapready

Fortunately I found the problem, it gets ridiculous from so simple. The detail is that the navbar was capping the button, I put a vertical LinearLayout and solved the problem.
