Modify MyShape.java in the example "Draw star on canvas" to fill the star.
package com.example.androiddrawpath;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
public class MyShape {
private Paint paint;
private Path path;
public MyShape() {
paint = new Paint();
paint.setColor(Color.BLUE);
paint.setStrokeWidth(3);
//paint.setStyle(Paint.Style.STROKE);
//paint.setStyle(Paint.Style.FILL);
paint.setStyle(Paint.Style.FILL_AND_STROKE);
path = new Path();
}
public void setCircle(float x, float y, float radius, Path.Direction dir){
path.reset();
path.addCircle(x, y, radius, dir);
}
public void setStar(float x, float y, float radius, float innerRadius, int numOfPt){
double section = 2.0 * Math.PI/numOfPt;
path.reset();
path.moveTo(
(float)(x + radius * Math.cos(0)),
(float)(y + radius * Math.sin(0)));
path.lineTo(
(float)(x + innerRadius * Math.cos(0 + section/2.0)),
(float)(y + innerRadius * Math.sin(0 + section/2.0)));
for(int i=1; i<numOfPt; i++){
path.lineTo(
(float)(x + radius * Math.cos(section * i)),
(float)(y + radius * Math.sin(section * i)));
path.lineTo(
(float)(x + innerRadius * Math.cos(section * i + section/2.0)),
(float)(y + innerRadius * Math.sin(section * i + section/2.0)));
}
path.close();
}
public Path getPath(){
return path;
}
public Paint getPaint(){
return paint;
}
}
