POHow are you supposed to use a ShapeDrawable with a PathShape to draw a line on a custom View?

copied!<p>I am attempting to draw a line in a custom <code>View</code>. Here I've created a simple <code>Path</code> with just a single segment, created a <code>PathShape</code> from that, and finally stuck that into a <code>ShapeDrawable</code> with the intention of using that to draw on the <code>Canvas</code> inside <code>onDraw()</code>. However, this does not work. See my example, here.</p> <pre><code>package com.example.test; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.graphics.Path; import android.graphics.drawable.ShapeDrawable; import android.graphics.drawable.shapes.PathShape; import android.util.Log; import android.view.View; public class TestView extends View { private Path mPath = null; private Paint mPaint = null; private PathShape mPathShape = null; private ShapeDrawable mShapeDrawable = null; public TestView(Context context) { super(context); } private void init() { int width = this.getWidth() / 2; int height = this.getHeight() / 2; Log.d("init", String.format("width: %d; height: %d", width, height)); this.mPath = new Path(); this.mPath.moveTo(0, 0); this.mPath.lineTo(width, height); this.mPaint = new Paint(); this.mPaint.setColor(Color.RED); this.mPathShape = new PathShape(this.mPath, 1, 1); this.mShapeDrawable = new ShapeDrawable(this.mPathShape); this.mShapeDrawable.getPaint().set(this.mPaint); this.mShapeDrawable.setBounds(0, 0, width, height); } @Override protected void onLayout(boolean changed, int left, int top, int right, int bottom) { super.onLayout(changed, left, top, right, bottom); // Doing this here because in the constructor we don't have the width and height of the view, yet this.init(); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); Log.d("onDraw", "Drawing"); // This works, but won't let me do what I'm really trying to do canvas.drawLine(0.0f, 0.0f, this.getWidth() / 2.0f, this.getHeight() / 2.0f, this.mPaint); // This should work, but does not //this.mPathShape.draw(canvas, this.mPaint); // This should work, but does not //this.mShapeDrawable.draw(canvas); } } </code></pre> <p>As you can see from my comments in the <code>onDraw()</code> method, neither using the <code>PathShape</code> nor the <code>ShapeDrawable</code> to draw the <code>Path</code> onto the <code>Canvas</code> actually works. Nothing is drawn when I try. Does anyone have any idea why?</p> <p>The device I'm testing this on is running Android 4.1.1.</p>
