Draw rounded corner line along path, with CornerPathEffect.

Example to draw rounded corner line along path, by applying CornerPathEffect on path.


Modify MyView.java from the post.
package com.example.androidview;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.CornerPathEffect;
import android.graphics.Paint;
import android.graphics.Path;
import android.util.AttributeSet;
import android.view.View;

public class MyView extends View {

Paint paint;
Path path;

public MyView(Context context) {
super(context);
init();
}

public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}

public MyView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}

private void init() {
paint = new Paint();
paint.setColor(Color.BLUE);
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.STROKE);

path = new Path();
path.moveTo(50, 50);
path.lineTo(50, 500);
path.lineTo(200, 500);
path.lineTo(200, 300);
path.lineTo(350, 300);

float radius = 50.0f;

CornerPathEffect cornerPathEffect =
new CornerPathEffect(radius);

paint.setPathEffect(cornerPathEffect);

}

@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawPath(path, paint);

}
