android - Recyclerview holder setting an image text instead of drawble -
i need display array texts image, displaying them text working, image not working. below explanation.
i have array of texts want display them in recycler view image.
string[] images = { "for_honor.png", "r.drawable.ghost_recon.png", "r.drawable.horizon_zerod.png", "r.drawable.mass_effect.png" }; setting them in way seems wrong not getting image
((myviewholder) holder).getmdataimgview().getresources().getidentifier(name,"drawable","com.example.pkg.pg.adapters"); however code working show me them text not image
// ((myviewholder) holder).getmdatatextview().settext(name); this code im main activity
maingridrecview = (recyclerview) findviewbyid(r.id.maingridrc); maingridrecviewlayoutmanager = new linearlayoutmanager(context); maingridrecview.setlayoutmanager(maingridrecviewlayoutmanager); maingridrecviewadapter = new maingridrvadapter( datahorizontal,datavertical,mainactivity.this); maingridrecview.setadapter(maingridrecviewadapter); this maingridrvadapter

change images array ints:
int[] images = { r.drawable.for_honor, r.drawable.ghost_recon, r.drawable.horizon_zerod, r.drawable.mass_effect }; and set image so:
int resourceid = images[position]; // <-- apply actual logic here ...getmdataimgview().setimageresource(resourceid);
