One reason is that there is no location in the layout file to show the list.
For example: The following layout
<com.xxx.view.baselistview
Android:id= "@+id/list_find"
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"
Android:cachecolorhint= "@android: Color/transparent"
android:divider= "@drawable/base_horizontal_line"
android:dividerheight= "1DP"
Android:fadingedgelength= "0DP"
Android:fastscrollenabled= "true"
android:paddingbottom= "10DP"/>
<com.xxx.view.baselistview
Android:id= "@+id/list_article"
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"
Android:cachecolorhint= "@android: Color/transparent"
android:divider= "@drawable/base_horizontal_line"
android:dividerheight= "1DP"
Android:fadingedgelength= "0DP"
Android:fastscrollenabled= "true"
android:paddingbottom= "10DP"/>
The first name is List_find's view height is match_parent, has filled the space, resulting in the first name of the List_article view does not show the space, so that the view does not execute GetView method, the data is not displayed.
Also, if the getcount result of view is 0, the GetView method is not executed.
One reason that the Android GetView method does not perform is that there is no location in the layout file to display the list
