【问题讨论】：
最好也向我们展示 XML。 显示您的 recyclerview 项目的 XML 文件 发布您的应用级别build.gradle 文件。
指出你的com.shixxels.thankgodrichard.spotpopfinal.adapter.RecyclerAdapter.onCreateViewHolder(RecyclerAdapter.java:64) 和com.shixxels.thankgodrichard.spotpopfinal.adapter.RecyclerAdapter.onCreateViewHolder(RecyclerAdapter.java:27)。还显示围绕这些行使用的 XML。
请在上面的代码中指出你的第 64 行和第 27 行。
【参考方案1】：
如果您在 ImageView 中使用矢量图标作为背景，并且 android 版本低于 5.0，则 imageview 会导致此崩溃。尝试使用<android.support.v7.widget.AppCompatImageView 而不是ImageView，并且不要忘记在您的Java 代码中声明并使用appCompatImageView 投射您的imageview。
要将矢量设置为背景，请使用此 xml 属性：app:srcCompat 选择颜色使用 android:tint，最后在您的 gradle 文件中，您必须添加对矢量的支持：
android
//...
defaultConfig
//...
vectorDrawables
useSupportLibrary = true
【讨论】：
【参考方案2】：看起来你实际上并没有夸大ImageView。
private List<FeedAdapter> mDataList;
private LayoutInflater inflater;
public RecyclerAdapter(Context context, List<FeedAdapter> data)
inflater = LayoutInflater.from(context);
this.mDataList = data;
this.context = context;
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
switch (viewType) // Create the Prime and Non-Prime row Layouts
case Image_digit:
ViewGroup myLayout = (ViewGroup) inflater.inflate(R.layout.list_item, parent, false);
ImageView myImage = (ImageView) myLayout.findViewById(R.id.my_image_id);
MyViewHolder_Images holderPrime = new MyViewHolder_Images(myImage);
return holderPrime;
【讨论】：
我不仅仅是在膨胀 ImageView。还有其他观点。这就是我使用 ViewGroup 的原因以上是关于在 RecyclerView 上膨胀类 ImageView 时出错的主要内容，如果未能解决你的问题，请参考以下文章
