How to fill a Path in Android with a linear gradient?


While steelbytes' answer will probably give you more control over the individual sections of the gradient, you can do it without the path:

Paint m_Paint = new Paint();protected void onDraw(Canvas canvas){    super.onDraw(canvas);    // start at 0,0 and go to 0,max to use a vertical    // gradient the full height of the screen.    m_Paint.setShader(new LinearGradient(0, 0, 0, getHeight(), Color.BLACK, Color.WHITE, Shader.TileMode.MIRROR));    canvas.drawPaint(m_Paint);}


this may help.

Note: it's not efficient to create the Paint etc in every call to onDraw. This is just an demonstration of LinearGradient shader

protected void onDraw(Canvas canvas){    super.onDraw(canvas);    int w = getWidth();    int h = getHeight();    Paint p = new Paint(Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);    Path pth = new Path();    pth.moveTo(w*0.27f,0);    pth.lineTo(w*0.73f,0);    pth.lineTo(w*0.92f,h);    pth.lineTo(w*0.08f,h);    pth.lineTo(w*0.27f,0);    p.setColor(0xff800000);    p.setShader(new LinearGradient(0,0,0,h,0xff000000,0xffffffff,Shader.TileMode.CLAMP));    canvas.drawPath(pth,p);}
