When running. The app will automatically collapse as soon as it slides.

At the beginning:

I always thought it was an issue of event distribution. I haven't found java. Lang. nullpointerexception in exception dispatching input event. After debugging for a long time. Where is it! I have no clue after looking for a morning.

After checking, when the getview () method in the listview adapter finds that convertview

The view is not assigned a value and the returned value is view.

Solution:

View view = convertview;

Code:

@ Overridepublic view getview (INT position, view convertview, viewgroup parent) {// todo needs to process the listview layout log for the new details. I ("love", "--- getcount () size =" + this. getcount (); // view = convertview; If (view = NULL) {view = Inflater. inflate (R. layout. fragment_new_fashtion_list_item, parent, false);} If (view! = NULL) {viewholder holder = (viewholder) view. gettag (); If (holder = NULL) {holder = new viewholder (); holder. newimageview = (imageview) view. findviewbyid (R. id. new_fashtion_item_image); holder. newtitleview = (textview) view. findviewbyid (R. id. new_fashtion_item_title); holder. newsharebtn = (radiobutton) view. findviewbyid (R. id. new_fashtion_rj_btn); holder. newcollectionbtn = (radiobutton) view. findviewbyid (R. id. new_fashtion_collection_btn); holder. newpricebtn = (radiobutton) view. findviewbyid (R. id. new_fashtion_price_btn); view. settag (holder);} // obtain the current data entity. Newstyleitementity entity = (newstyleitementity) newstylelists. get (position); log. I ("love", "--- position =" + position); log. I ("love", "--- entity =" + newstylelists. get (position ). getprice (); holder. newtitleview. settext (newstylelists. get (position ). gettitle (); holder. newpricebtn. append (newstylelists. get (position ). getprice (); // download the image:} return view ;}

Exception dispatching input event. Use xlistview
