android - How to add startActivity into OnClickListener in Adapter? -
here adapter.
public class myadapter extends recyclerview.adapter<myadapter.viewholder> { private static final int type_header = 0; // declaring variable understand view being worked on // if viaew under inflation , population header or item private static final int type_item = 1; private string mnavtitles[]; // string array store passed titles value mainactivity.java private int micons[]; // int array store passed icons resource value mainactivity.java private string name; //string resource header view name private int profile; //int resource header view profile picture private string email; //string resource header view email static context context; // creating viewholder extends recyclerview view holder // viewholder used to store inflated views in order recycle them public static class viewholder extends recyclerview.viewholder { int holderid; textview textview; imageview imageview; imageview profile; textview name; textview email; context contxt; intent intent; public viewholder(view itemview,int viewtype,context c) { // creating viewholder constructor view , viewtype parameter super(itemview); contxt = c; itemview.setclickable(true); itemview.setonclicklistener(click); // here set appropriate view in accordance the view type passed when holder object created if(viewtype == type_item) { textview = (textview) itemview.findviewbyid(r.id.rowtext); // creating textview object id of textview item_row.xml imageview = (imageview) itemview.findviewbyid(r.id.rowicon);// creating imageview object id of imageview item_row.xml holderid = 1; // setting holder id 1 object being populated of type item row } else{ name = (textview) itemview.findviewbyid(r.id.name); // creating text view object header.xml name email = (textview) itemview.findviewbyid(r.id.email); // creating text view object header.xml email profile = (imageview) itemview.findviewbyid(r.id.circleview);// creating image view object header.xml profile pic holderid = 0; // setting holder id = 0 object being populated of type header view } } private view.onclicklistener click=new view.onclicklistener(){ @override public void onclick(view v) { switch(getposition()) { case 1: intent = new intent(context, me.class); startactivity(intent); } } }; } myadapter(string titles[],int icons[],string name,string email, int profile,context passedcontext){ // myadapter constructor titles , icons parameter // titles, icons, name, email, profile pic passed main activity mnavtitles = titles; //have seen earlier micons = icons; name = name; email = email; profile = profile; //here assign passed values values declared here this.context = passedcontext; //in adapter } //below first ovverride method oncreateviewholder called when viewholder //created, in method inflate item_row.xml layout if viewtype type_item or else inflate header.xml // if viewtype type_header // , pass view holder @override public myadapter.viewholder oncreateviewholder(viewgroup parent, int viewtype) { if (viewtype == type_item) { view v = layoutinflater.from(parent.getcontext()).inflate(r.layout.item_row,parent,false); //inflating layout viewholder vhitem = new viewholder(v,viewtype,context); //creating viewholder , passing object of type view return vhitem; // returning created object //inflate layout , pass view holder } else if (viewtype == type_header) { view v = layoutinflater.from(parent.getcontext()).inflate(r.layout.header,parent,false); //inflating layout viewholder vhheader = new viewholder(v,viewtype,context); //creating viewholder , passing object of type view return vhheader; //returning object created } return null; } //next override method called when item in row needed displayed, here int position // tells item @ position being constructed displayed , holder id of holder object tell // view type being created 1 item row @override public void onbindviewholder(myadapter.viewholder holder, int position) { if(holder.holderid ==1) { // list view going called after header view decrement // position 1 , pass holder while setting text , image holder.textview.settext(mnavtitles[position - 1]); // setting text array of our titles holder.imageview.setimageresource(micons[position -1]);// settimg image array of our icons } else{ holder.profile.setimageresource(profile); // set resources header view holder.name.settext(name); holder.email.settext(email); } } // method returns number of items present in list @override public int getitemcount() { return mnavtitles.length+1; // number of items in list +1 titles including header view. } // witht following method check type of view being passed @override public int getitemviewtype(int position) { if (ispositionheader(position)) return type_header; return type_item; } private boolean ispositionheader(int position) { return position == 0; } }
here onclicklistener within
private view.onclicklistener click=new view.onclicklistener(){ @override public void onclick(view v) { switch(getposition()) { case 1: intent = new intent(context, me.class); startactivity(intent); // error! } } }; } i'm trying put startactivity in it, it's getting error.
how can handle it?
try below.
private view.onclicklistener click=new view.onclicklistener(){ @override public void onclick(view v) { switch(getposition()) { case 1: intent = new intent(context, me.class); context.startactivity(intent); // or v.getcontext().startactivity(intent); } } };
