Example 1 with CalibrationMarker

use of com.peterlaurence.trekadvisor.menu.mapcalibration.components.CalibrationMarker in project TrekAdvisor by peterLaurence.

the class MapCalibrationFragment method setMap.

 * Sets the map to generate a new {@link TileView}.
 *
 * @param map The new {@link Map} object

    /* Map calibration */
    tileView.defineBounds(0, 0, 1, 1);
    /* The calibration marker */
    mCalibrationMarker = new CalibrationMarker(this.getContext());
    MarkerTouchMoveListener.MarkerMoveCallback callback = new CalibrationMarkerMoveCallback();
    mCalibrationMarker.setOnTouchListener(new MarkerTouchMoveListener(tileView, callback));
    tileView.addMarker(mCalibrationMarker, 0.5, 0.5, -0.5f, -0.5f);
    /* The BitmapProvider */
    tileView.setBitmapProvider(map.getBitmapProvider());

Example 2 with CalibrationMarker

use of com.peterlaurence.trekadvisor.menu.mapcalibration.components.CalibrationMarker in project TrekAdvisor by peterLaurence.

the class MapCalibrationFragment method moveCalibrationMarker.

/**
 * Before telling the {@link TileView} to move a marker, we save its relative coordinates so we
 * can use them later on calibration save.
 */
private static void moveCalibrationMarker(TileView tileView, View view, double x, double y) {
    CalibrationMarker calibrationMarker = (CalibrationMarker) view;
    calibrationMarker.setRelativeX(x);
    calibrationMarker.setRelativeY(y);
    tileView.moveMarker(view, x, y);
