The most important feature of this class is the ability to convert the layout of XML representations into VIEW. For the sake of understanding, we can compare it to Findviewbyid (), both of which instantiate an object, and the difference is that Findviewbyid () is instantiated for the specific widget control under the XML layout file, and Layoutinflater is looking for res/ The XML layout file under Layout/is instantiated.</p></p><p><p>(1) Create</p></p><p><p>Layoutinflater inflater= (layoutinflater) Context.getsystemservice (context.layout_inflater_service);</p></p><p><p>Layoutinflater Inflater = Layoutinflater.from (activity.this);</p></p><p><p>Layoutinflater Inflater = Getlayoutinflater ();</p></p><p><p>The three methods are essentially the Same.</p></p><p><p>(2) Inflate ()</p></p><p><p>Use Layoutinflater.inflate () to convert the layout file to View.</p></p><p><p>View view = Inflater.inflate (r.layout.block_gym_album_list_item, null);</p></p><p><p></p></p><p><p>3.
