Set initial scale #12

Closed dbof10 closed 4 years ago

dbof10 commented 4 years ago

Hi, thanks for the library. I'm new to this lib. I have some questions

  1. I want set the map with some initial scale value when it first renders
  2. In addition, I want to run some ValueAnimator to change scale value.
  3. Look at MapMarkersFragment, a callout is added every time marker is clicked. Does the lib remove the callout when tap outside?

Hi,

  1. You can use setStartScale method on MapViewConfiguration builder. For example:
val config = MapViewConfiguration(5, 8192, 8192, tileSize, 
tileStreamProvider).setStartScale(1.5f)

  1. You can either use MapView.smoothScaleTo(destScale) or use your own animator and change the scale by setting a new value for the scale property of the MapView at each animation step.

  2. Yes the lib removes the callout when taping outside

Actually there is one more question, after startScaleValue how to move it to specific region like camera api from google map?

There's also the slideToAndCenterWithScale(x, y, scale) api.
