圖像中的Android塗料

Question

我需要使用畫布在字母A內的空白區域繪製顏色。我怎樣才能做到這一點？

Answer 1

繪製多邊形時使用繪畫顏色。示例：

Paint red = new Paint(); 
    red.setColor(android.graphics.Color.RED); 
    red.setStyle(Paint.Style.FILL); 

    Path path = new Path(); 
    path.moveTo(point1.x, point1.y); 
    path.lineTo(point2.x, point2.y); 
    path.moveTo(point2.x, point2.y); 
    path.lineTo(point3.x, point3.y); 
    path.moveTo(point3.x, point3.y); 
    path.lineTo(point1.x, point1.y); 
    path.close(); 

    canvas.drawPath(path, red);
