resources - android studio find by id, where id is a variable passed as a parameter -

i have hundreds of buttons, same listener , action, different names. here 1 name goes1:

public void goes1(){     final mediaplayer mp = mediaplayer.create(this, r.raw.goes1);     play_text_view = (textview) this.findviewbyid(r.id.goes1);     play_text_view.setonclicklistener(new view.onclicklistener(){         public void onclick(view v) {             try {                 lirexml("goes1");             } catch (xmlpullparserexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             }             mp.start();         }     }); } 

i have 1 method name of button passed method parameter. this, string parameter mot:

public void playmot(string mot){     final mediaplayer mp = mediaplayer.create(this, r.raw.mot);     play_text_view = (textview) this.findviewbyid(r.id.mot);     play_text_view.setonclicklistener(new view.onclicklistener(){         public void onclick(view v) {             try {                 lirexml(mot);             } catch (xmlpullparserexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             }             mp.start();         }     }); } 

but r.raw.mot , r.id.mot don't this! should have hundreds of buttons, or there way around problem? thanks

you looking resources.getidentifier. looks resource id string name , type.

public void playmot(string mot) {     resources res = getresources();     // should error check this, returns 0 on error.     final rawid = res.getidentifier(mot, "raw", getpackagename());       final mediaplayer mp = mediaplayer.create(this, rawid);     // should error check this, returns 0 on error.     final resid = res.getidentifier(mot, "id", getpackagename());       play_text_view = (textview) this.findviewbyid(resid);     ...
