在 RecyclerView 上膨胀 Class ImageView 时出错
Error inflating Class ImageView on RecyclerView
我使用最低 SDK 15 和目标 23 构建了一个应用程序，并且我在 RecyclerView 中有不同的看法。
应用程序在 android 版本 => 5.0 上运行良好，但在 android 版本 < 5.0 上崩溃并显示以下错误消息

看起来你实际上并没有给 ImageView 充气。
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;
如果您在ImageView中使用矢量图标作为背景并且android的版本低于5.0，imageview将导致此崩溃。尝试使用 <android.support.v7.widget.AppCompatImageView 而不是 ImageView 并且不要忘记在您的 java 代码中使用 appCompatImageView 声明和投射您的图像视图。
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
}
}

看起来你实际上并没有给 ImageView 充气。
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;
如果您在ImageView中使用矢量图标作为背景并且android的版本低于5.0，imageview将导致此崩溃。尝试使用 <android.support.v7.widget.AppCompatImageView 而不是 ImageView 并且不要忘记在您的 java 代码中使用 appCompatImageView 声明和投射您的图像视图。
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
}
}
