Error inflating class reported an error

Error inflating class is reported when R.layout.dialog_item contains theme when filling the layout

LayoutInflater inflater = LayoutInflater.from(mContext);
 View  view = inflater.inflate(R.layout.dialog_item, null);

There is a theme in the layout, you need to add it to the corresponding AndroidManifest, and add the theme to the activity

    <activity
            android:name=".MyActivity"
            android:theme="@style/SampleTheme.Light"/>

This will solve it
