Android RecyclerView: How to avoid scroll interruption(scroll twice) when scroll state is not IDLE? -

how avoid recyclerview being scrolled when scrollstate not idle ?

i have tried ideas overriding canscrollhorizontally() in linearlayoutmanager , return false when scrollstate != idle or same concept applied dispatchtouchevent() in activity, stuck screen forever.

i tried asyntask method while loop made never escape doinbackground , go onpostexercute:

 @override         public void onscrollstatechanged(recyclerview recyclerview, int newstate) {             super.onscrollstatechanged(recyclerview, newstate);              if (previousscrollstate != 0) {                  new asynctask<void, void, boolean>() {                      @override                     protected boolean doinbackground(void... params) {                          while (previousscrollstate != 0) {                             log.i(tag, "doinbackground " + previousscrollstate);                         }                          return true;                     }                      @override                     protected void onpreexecute() {                         super.onpreexecute();                         reclist.settouchenabled(false);                     }                      @override                     protected void onpostexecute(boolean avoid) {                         super.onpostexecute(avoid);                         reclist.settouchenabled(true);                         log.i(tag, "onpostexecute " + previousscrollstate);                     }                 }.execute();              }              previousscrollstate = newstate; } 

my purpose avoid user skip page(scroll twice or more @ same time). how can achieve it? sharing.

not sure if bad solution before better answer come out:

 @override         public void onscrollstatechanged(recyclerview recyclerview, int newstate) {             super.onscrollstatechanged(recyclerview, newstate);              if (previousscrollstate != recyclerview.scroll_state_idle) {                  if (asynccheckscrollstate == null || asynccheckscrollstate.iscancelled()) {                      asynccheckscrollstate = new asynccheckscrollstate();                     asynccheckscrollstate.execute();                  }             }          // ...          previousscrollstate = newstate; } 

and:

public class asynccheckscrollstate extends asynctask<void, void, void> {      @override     protected void onpreexecute() {         super.onpreexecute();         reclist.settouchenabled(false);     }      @override     protected void doinbackground(void... params) {          try {              while (previousscrollstate != 0) {                 if (iscancelled()) {                     log.i(tag, "canceled ");                     break;                 }             }          } catch (exception e) {         } {             this.cancel(true);         }          return null;     }      @override     protected void oncancelled() {         super.oncancelled();         reclist.settouchenabled(true);     } }
