Thread: How to get x & y coordinates from current position in Java(Android Studio)

What values are in the x and y variables? Are they supposed to hold the coordinates of some component?
What is the component that you are working with?

coordinates from me moving the tablet

What are the x and y measuring? Where is the 0,0 point?
It sounds like you want the coordinates for the position of the tablet in a room where you can move the tablet from one side to the other.
One of the corners of the room is the 0,0 point and you want the distance from that corner in the x and y directions.

I have no idea how your tablet senses walls to be able to compute its distance from them.
What feature(s) does your tablet have to sense walls? Can it be calibrated to measure in feet or meters?

I do not know of any sensing device on an android tablet that measures distances to walls from within a room.
Most tablets have GPS which can give you a position in degrees of latitude and longitude.

Given the lat and long of two places, the distance between them can be computed.

This site has code for measuring distances: https://github.com/j4velin/MapsMeasure

The general formulas for computing the distance between two points located by lat and long do not require the Google API. I thought that the Google API was required if you were going to use maps from Google to display points on a map of the earth. If the points are close together you can use plain trigonometry with some compensation for the latitude the points are at. I forget what the function is (sin or cos or ??) used to reduce the distance at higher latitudes. As you go North, the distance between lines of longitude get less. For latitude, the distance between lines does not change with longitude.

I have gotten permission from Google to use the API for its maps and it has not cost me anything.

Here is my android app that computes distances: https://github.com/NormR/Maps4Norm

Sorry, I don't think that GPS coordinates from a tablet are accurate enough to be able to get the positions of the corners of a house on a map of the earth. I have found that GPS positions can be off by several feet/meters.

Why are you using the terms x and y? Are you talking about latitude and longitude?

I have no idea how pictures of a house can be used to get an x,y value.
Where is the 0,0 point of reference? Which way does the axis run?

How does the tablet sense its position so it can be recorded?

Why do you think your tablet can sense its position inside of a house? The only position sensing feature I know of for a tablet is GPS.
We have come full circle back to post#8.

I have not seen any of those apps for the tablet. I can only imagine that they use an image from the camera to do some calculations.

I suppose if you have a scale for the span of distance shown on the image, you can then select spots on the image to be measured and compute the distance between click spots using the given scale.
I wrote a javascript program several years ago (before Google Maps) to measure the distance on a map. It displays a map with a scale and requires you to select the scale from a drop down and then click and move the cursor on the maps's scale bar to calibrate the number of pixels/distance. After setting the scale, You can the click on the map and move the cursor to where you want the distance measured. The distance is displayed in a textbox at the top.
Here is a link for a demo: Measure trip distance
