java - Reading a text file dynamically on user selection in Android -

i building android application reads text files. now,i have multiple text files in sdcard . location of files /sdcard/textfile/
filenames: abc.txt def.txt ghi.txt

i want when users select 1 of file,the selected file should read. know code read single file i.e

file sdcard = environment.getexternalstoragedirectory(); file file = new file(sdcard,pathtofile);  bufferedreader br = new bufferedreader(new filereader(file)); 

pathtofile stores path file abc.txt defined .

is there way can pass filepath file object file user selected currently,it works abc.txt have defined path in pathtofile

you can make list of items in textfile folder , save in list user can choose from.

public class directorybrowser extends listactivity {  private list<string> items = null; private file currentdirectory; private arrayadapter<string> filelist;  @override public void oncreate(bundle icicle) {     super.oncreate(icicle);     currentdirectory = new file("/sdcard/textfile");     getfiles(currentdirectory.listfiles());  }  @override protected void onlistitemclick(listview l, view v, int position, long id){     int selectedrow = (int)id;          currentdirectory = new file(items.get(selectedrow));         if(currentdirectory.isdirectory()){             getfiles(currentdirectory.listfiles());         }else{             //if selected file not directory. filename             currentdirectory.getpath();         } }  private void getfiles(file[] files){     items = new arraylist<string>();     for(file file : files){         items.add(file.getpath());     }     filelist = new arrayadapter<string>(this,r.layout.list_text, items);     setlistadapter(filelist); }   }
