How to draw a line based on the coordinates in the map.xml?

[mohshaat1990]

on class poly area there is comment ondraw function
@OverRide
public void onDraw(Canvas canvas) {
// draw the bounding box
/* canvas.drawRect(left * mResizeFactorX + mScrollLeft,
top * mResizeFactorY + mScrollTop,
right * mResizeFactorX + mScrollLeft,
bottom * mResizeFactorY + mScrollTop,
textOutlinePaint);*/

i used this function to draw polygon based on coordinates in map.xml
Paint paint = new Paint();
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth(4);
paint.setColor(Color.RED);
Path p = new Path();
/* p.moveTo(left * mResizeFactorX + mScrollLeft, top * mResizeFactorY + mScrollTop);
p.lineTo(left * mResizeFactorX + mScrollLeft, top * mResizeFactorY + mScrollTop);
p.lineTo(right * mResizeFactorX + mScrollLeft, top* mResizeFactorY + mScrollTop);/
p.moveTo(xpoints.get(0) * mResizeFactorX + mScrollLeft, ypoints.get(0) * mResizeFactorY + mScrollTop);
for(int a=0;a<xpoints.size();a++)
p.lineTo(xpoints.get(a) mResizeFactorX + mScrollLeft, ypoints.get(a) * mResizeFactorY + mScrollTop);
/* p.moveTo(xpoints.get(0) * mResizeFactorX + mScrollLeft, ypoints.get(0) * mResizeFactorY + mScrollTop);
p.lineTo(xpoints.get(0)* mResizeFactorX + mScrollLeft, ypoints.get(0) * mResizeFactorY + mScrollTop);
p.lineTo(xpoints.get(1) * mResizeFactorX + mScrollLeft, ypoints.get(1) * mResizeFactorY + mScrollTop);
p.lineTo(xpoints.get(2) * mResizeFactorX + mScrollLeft, ypoints.get(2) * mResizeFactorY + mScrollTop);*/
p.close();
// p.lineTo(200, 100);
// p.lineTo(240, 155);
// p.lineTo(250, 175);
// p.lineTo(20, 20);
canvas.drawPath(p, paint);
