Question

我有一个以下矢量drawable：

<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"

</vector>

在Android Studio的预览标签上，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作为其源代码时，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，设置在别处。有谁知道我怎么解决这个问题？

Answer 1

好的，这是解决方案。

问题的根源

问题在于xml中的填充规则：android:fillType="evenOdd"。 Android直到Nougat版本才支持此参数，所以我们必须以某种方式避免它。正如@LewisMcGeary指出的那样，对这个topis有一个很好的解释：Marc Allison's blog。有关此填充规则的更多信息，请参阅@Duopixel建议的this link。

我的解决方案

我通过更改软件解决了这个问题。我使用了前面提到的博客文章中建议的online tool，其中包含以下设置：

然后我将其保存到xml，内容如下：
