Android 绘制点

如何用画布绘制完整的圆或点？我使用画布和路径+绘画类

my code:

@Override
public boolean onTouchEvent(MotionEvent event) {
    float eventX = event.getX();
    float eventY = event.getY();
    System.out.println(event.getAction());
    switch (event.getAction()) {
    case MotionEvent.ACTION_DOWN:
        path.moveTo(eventX, eventY);
        return true;
    case MotionEvent.ACTION_MOVE:
        path.lineTo(eventX, eventY);
        break;
    case MotionEvent.ACTION_UP:
        path.addCircle(eventX, eventY, .1F, Path.Direction.CW);
        break;
    default:
        return false;
    }

    // Schedules a repaint.
    invalidate();
    return true;
}

你的油漆必须是“满的”，为此你必须写下这个

paint.setStyle(Paint.Style.FILL);

然后画出你的圆圈

canvas.drawCircle(x, y, radius, paint);

我希望它会有所帮助
