Example 96 with PointF

use of android.graphics.PointF in project StreetComplete by westnordost.

the class MainActivity method onLeaveNote.

@Override
public void onLeaveNote(String note, ArrayList<String> imagePaths, Point screenPosition) {
    int[] mapPosition = new int[2];
    View mapView = mapFragment.getView();
    if (mapView == null)
        return;
    mapView.getLocationInWindow(mapPosition);
    PointF notePosition = new PointF(screenPosition);
    notePosition.offset(-mapPosition[0], -mapPosition[1]);
    LatLon position = mapFragment.getPositionAt(notePosition);
    questController.createNote(note, imagePaths, position);
    unsyncedChangesCounter.increase(null);
    closeBottomSheet();
}

Example 97 with PointF

use of android.graphics.PointF in project Slide by ccrama.

the class SubsamplingScaleImageView method onSizeChanged.

/**
 * On resize, preserve center and scale. Various behaviours are possible, override this method to use another.
 */
@Override

Example 98 with PointF

use of android.graphics.PointF in project Slide by ccrama.

the class SubsamplingScaleImageView method vTranslateForSCenter.

/**
 * Get the translation required to place a given source coordinate at the center of the screen, with the center
 * adjusted for asymmetric padding. Accepts the desired scale as an argument, so this is independent of current
 * translate and scale. The result is fitted to bounds, putting the image point as near to the screen center as permitted.
 */

    int vxCenter = getPaddingLeft() + (getWidth() - getPaddingRight() - getPaddingLeft()) / 2;
    int vyCenter = getPaddingTop() + (getHeight() - getPaddingBottom() - getPaddingTop()) / 2;
    if (satTemp == null) {
        satTemp = new ScaleAndTranslate(0, new PointF(0, 0));

    satTemp.vTranslate.set(vxCenter - (sCenterX * scale), vyCenter - (sCenterY * scale));
    fitToBounds(true, satTemp);
    return satTemp.vTranslate;
}

Example 99 with PointF

use of android.graphics.PointF in project Slide by ccrama.

the class SubsamplingScaleImageView method limitedSCenter.

/**
 * Given a requested source center and scale, calculate what the actual center will have to be to keep the image in
 * pan limits, keeping the requested center as near to the middle of the screen as allowed.
 */
private PointF limitedSCenter(float sCenterX, float sCenterY, float scale, PointF sTarget) {
    PointF vTranslate = vTranslateForSCenter(sCenterX, sCenterY, scale);
    int vxCenter = getPaddingLeft() + (getWidth() - getPaddingRight() - getPaddingLeft()) / 2;
    int vyCenter = getPaddingTop() + (getHeight() - getPaddingBottom() - getPaddingTop()) / 2;
    float sx = (vxCenter - vTranslate.x) / scale;
    float sy = (vyCenter - vTranslate.y) / scale;
    sTarget.set(sx, sy);
    return sTarget;
}

Example 100 with PointF

use of android.graphics.PointF in project Slide by ccrama.

the class SubsamplingScaleImageView method resetScaleAndCenter.

/**
 * Fully zoom out and return the image to the middle of the screen. This might be useful if you have a view pager
 * and want images to be reset when the user has moved to another page.
 */
public final void resetScaleAndCenter() {
    this.anim = null;
    this.pendingScale = limitedScale(0);

    } else {
