嗨，我尝试在我的应用程序中使用 xml vecotr 作为可绘制对象，并且在 API 25 中一切正常，但是当我在 API 16 上尝试时，出现此错误。仅当我尝试以编程方式加载矢量时才会收到错误，当我在布局中将其用作 ImageView 背景时，我没有收到错误。

在 Editor.java（扩展 AppCompatActivity）中，我尝试了这两个（都没有工作）：
Drawable upArrow=getResources().getDrawable(R.drawable.chevron_left);
Drawable upArrow = ContextCompat.getDrawable(this, R.drawable.chevron_left).getCurrent();
矢量 chevron_left.xml：
<!-- drawable/chevron_left.xml -->
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:height="42dp"
android:width="42dp"
android:viewportWidth="24"
android:viewportHeight="24">
<path android:fillColor="#fff" android:pathData="M15.41,16.58L10.83,12L15.41,7.41L14,6L8,12L14,18L15.41,16.58Z" />
</vector>
摇篮：
defaultConfig {
applicationId "com....."
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
multiDexEnabled true
}
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:support-vector-drawable:25.3.1'
compile 'com.android.support:appcompat-v7:25.3.1'
只需对 vectorDrawables.useSupportLibrary 应用 false 即可。像这样：-
vectorDrawables.useSupportLibrary = false
原因是 Vector drawable 不适用于棒棒糖下面的 api。它存在一些问题。但是您可以声明 vector drawable & 并且可以使用以下棒棒糖版本但您必须将 useSupportLibrary 设置为 false 以便 android studio 将为您创建 png 文件:)
