我一直在尝试在我的片段类中添加Imageview，但是我得到了错误，在我运行应用程序之后，它因“Error Inflating class Imageview”错误而停止。但是，当我删除Imageview并添加Textview或Button时，它只能正常工作，只有Imageview和ImageButton ......它会抛出错误。
我尝试将android：src更改为app：srcCompat =但它也不起作用，图像文件在60kb的范围内也非常小。
这是错误日志

使用android.support.v7.widget.AppCompatImageButton代替ImageButton
正在使用app:srcCompat
用法应该是这样的： -
android.support.v7.widget.AppCompatImageButton - ＆gt; app:srcCompat
ImageButton ----＆gt; android:src
在你的xml中： -
<android.support.v7.widget.AppCompatImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
.....
.....
app:srcCompat="@drawable/eka"
/>
