Example 46 with PathMeasure

use of android.graphics.PathMeasure in project MaterialCalendar by Haoxiqiang.

the class WeatherTemplateView method getPoints.

protected PathPoints[] getPoints(Path path, int size) {
    // Size of 100 indicates that, 100 points
    // would be extracted from the path
    PathPoints[] pointArray = new PathPoints[size];
    PathMeasure pm = new PathMeasure(path, false);
    float length = pm.getLength();
    float distance = 0f;
    float speed = length / size;
    int counter = 0;
    float[] aCoordinates = new float[2];
    while ((distance < length) && (counter < size)) {
        pm.getPosTan(distance, aCoordinates, null);
        pointArray[counter] = new PathPoints(aCoordinates[0], aCoordinates[1]);
        counter++;
        distance = distance + speed;
    }
    return pointArray;
}

Example 47 with PathMeasure

use of android.graphics.PathMeasure in project YhLibraryForAndroid by android-coco.
