But regarding performance, is data binding faster then using findViewById in native android ? 回答1: It looks to me that it is faster per the docs : Views With IDs A public final field will be generated for each View with an ID in the layout. The binding does a single pass on the View hierarchy, extracting the Views with IDs. This mechanism can be faster than calling findViewById for several Views. So it seems data binding only has to do a single pass over

How can I inspect a POST request and edit the form data before it gets sent to the server?
