android - 六边形 ProgressBar

Question

我正在尝试制作一款游戏，让用户获得经验值并提高等级，如下图所示。

我想通过使用进度条来实现这一点，但我无法制作一个六边形的进度条。

黄线应该随着用户积分的增加而增加。

谁能告诉我如何实现这一点？(我试过Custom ProgressBar，但没有成功。)

谢谢。

Answer 1

我设法更改了 Nilesh mentioned 的代码并制作了一个没有任何曲线的进度条。

这对我来说很好用。

现在我只需要弄清楚如何在进度条中插入图像。 :p

}

  @Override

    ObjectAnimator.ofFloat(this, "progress", 0, 
    pm.getLength()).setDuration(5 * 2500).start();
    Log.d(TAG, pm.getLength() + "");
}

  @Override
  protected void onDraw(Canvas canvas) {

      canvas.drawPath(segment, paint);

   }
 }
