安卓安卓知道四个点的坐标 怎么画实心梯形（比如1,1 1,2 2,3 2,2)照着例子就好

Answer 1

使用canvas.drawPath函数：

@Override

protected void onDraw(Canvas canvas) {

Paint paint = new Paint();
paint.setColor(Color.BLACK);
paint.setStyle(Paint.Style.FILL);

Path path = new Path();
path.moveTo(1, 1); 
path.lineTo(1, 2);
path.lineTo(2, 3);
path.lineTo(2, 2);
path.lineTo(1, 1);

canvas.drawPath(path, paint);

 }
