Edit :
item.xml is displaying perfectly on Lollipop based devices but it is not being displayed on Huawei Nexus 6P which is Marshmallow based Android phone .
Note : When I try setContentView(R.layout.item) then works fine on Huawei Nexus 6P . but It is throwing error when using with following code :
View itemViewTextAudio = inflater.inflate(R.layout.item, viewGroup, false);
