android - 显示为整圆的矢量绘图

Question

我有以下矢量绘图:

</vector>

在 Android Studio 的预览选项卡上，它看起来像这样(这就是所需要的):

但是当我以编程方式将其设置为 ImageView 作为其源时，使用代码:

imageMenuItem.setImageResource(R.drawable.keno);

它看起来像这样:

ImageView 的 xml 代码很简单:

<ImageView
    android:id="@+id/image_menu_item"
    style="@style/UpperItemsImageLeftMenu"
    app:srcCompat="@drawable/leftmenu_keno"
    android:layout_width="@dimen/upper_item_image_dim_left_menu"
    android:layout_height="@dimen/upper_item_image_dim_left_menu"
     />

深灰色是背景，设置在其他地方。有谁知道我该如何解决这个问题？

Answer 1

好的，解决方案如下。

问题根源

问题出在 xml 中的填充规则:android:fillType="evenOdd"。 Android直到Nougat版本才支持这个参数，所以我们必须想办法避免它。正如@LewisMcGeary 指出的，关于这个主题有一个很好的解释:Marc Allison's blog 。有关此填充规则的更多信息可以在 this link 上找到。正如@Duopixel 所建议的。

我的解决方案

我通过更改软件解决了这个问题。我用过这个online tool正如前面提到的博客文章所建议的，具有以下设置:

然后我将其保存到 xml 中，内容如下:
