添加背景图片时：错误膨胀类android.widget.ImageButton

Question

我不确定究竟是什么导致了这个问题，但每当我添加图像资源作为我的ImageButton的背景时，我都会遇到同样的错误。该应用刚刚开始，所以几乎没有任何代码。这是错误：

    @Override

        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

我已经尝试过你的代码，它对我有用。所以我认为你的问题是你的musicoff可绘制的，并且正是它的大小。

尝试更改此可绘制尺寸或尝试使用其他可绘制图像，它将起作用。
