Non scale-able element pointing to markers #447

Closed AlgirdasPundzius closed 6 years ago

AlgirdasPundzius commented 6 years ago

I need to make constant element (let's say X icon) which should be anchored to the top of TileView all the times and neither scale nor move with the TileView. However that X icon should draw a path to marker (which should move regarding the scale of the TileView). It is a bit hard to explain the idea so I have attached images to have a better understanding

So I'm not sure how to approach this issue, any help would be appreciated :)

There's nothing built-in that would do that. You probably want to use a FrameLayout or RelativeLayout, and put the X on a layer above the TileView, then you'll have to manually figure out where that point would be for the line drawing. The point would be roughly equal to (the actual position + tileView scroll * scale).
