here code, used.

madapter = new firebaserecycleradapter<note, firebasenoteviewholder>(note.class, r.layout.item_note, firebasenoteviewholder.class, mref) {     @override     public void populateviewholder(firebasenoteviewholder notemessageviewholder, final note notemessage, final int position) {         notemessageviewholder.settitle(notemessage.gettitle());         notemessageviewholder.setupdateddate(dateformat.getinstance().format(notemessage.getdatamodified()));          notemessageviewholder.itemview.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 //toast.maketext(getactivity(), notemessage.getdatamodified().tostring(), toast.length_long).show();                  databasereference.orderbychild("datamodified").equalto(notemessage.getdatamodified().tostring()).addlistenerforsinglevalueevent(                         new valueeventlistener() {                             @override                             public void ondatachange(datasnapshot datasnapshot) {                                  string key = datasnapshot.getkey();                                  toast.maketext(getactivity(), key, toast.length_long).show();                             }                               @override                             public void oncancelled(databaseerror databaseerror) {                              }                         });             }         });     } };

thanks in advance!

you getting parent key can try:

      databasereference.orderbychild("datamodified").equalto(notemessage.getdatamodified().tostring()).addlistenerforsinglevalueevent(           new valueeventlistener() {            @override           public void ondatachange(datasnapshot datasnapshot) {              string key = datasnapshot.getkey();             int positioncount=0;             for(datasnapshot note : datasnapshot.getchildren()){                 if(positioncount==position){                    firebase.child("notes").child(key).child(note .getkey()).removevalue();                    toast.maketext(getactivity(), note.getkey(), toast.length_long).show();                    }                positioncount++;             }         }       @override       public void oncancelled(databaseerror databaseerror) {                  }      });

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
