How to get data from database in my android table view as columns -


i have done following coding deriving data's table , displayed in android view table columns , rows.

the database coding is

public list<country> getallcountry() {     list<country> countrylist = new arraylist<country>();      //select query     string selectquery = "select * country_list";      sqlitedatabase db = this.getwritabledatabase();     cursor cursor = db.rawquery(selectquery, null);       (cursor.movetofirst(); !cursor.isafterlast(); cursor.movetonext())     {          country country = new country();             country.setid(cursor.getstring(0));             country.setname(cursor.getstring(1));             country.setnationalty(cursor.getstring(2));             country.setdate(cursor.getstring(3));               // adding person list             countrylist.add(country);     }      return countrylist;  }

the xml is

<tablelayout      android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:id="@+id/tab">   <tablerow       >           </tablerow>     </tablelayout>

the activity coding is

list<country> country = db.getallcountry();      stringbuilder builder = new stringbuilder();     (country c: country)     {                        builder.append(c.getid()).append(";")             .append(c.getname()).append(";")             .append(c.getnationalty()).append(";")             .append(c.getdate()).append("_");     }     //tv.settext(builder.tostring());      builder.tostring();      string st = new string(builder);     log.d("main",st);     string[] rows  = st.split("_");     tablelayout tablelayout = (tablelayout)findviewbyid(r.id.tab);     tablelayout.removeallviews();      for(int i=0;i<rows.length;i++){         log.d("rows",rows[i]);         string row  = rows[i];         tablerow tablerow = new tablerow(getapplicationcontext());         tablerow.setlayoutparams(new tablelayout.layoutparams(layoutparams.match_parent, layoutparams.wrap_content));         final string[] cols = row.split(";");          handler handler = null;          (int j = 0; j < cols.length; j++) {                          final string col = cols[j];                                              textview columsview = new textview(getapplicationcontext());             columsview.setlayoutparams(new tablerow.layoutparams(tablerow.layoutparams.wrap_content, tablerow.layoutparams.wrap_content));             columsview.settextcolor(color.black);             columsview.settext(string.format("%7s", col));                                             log.d("cols", string.format("%7s", col));             tablerow.addview(columsview);          }     }

the above code not printing in android emulator screen.

please have done wrong.

thanks in advance.

regards, dinesh

i guess missing tablelayout.addview(tablerow) on last line of 1st loop after coming out of 2nd loop..else row not added..

vb.net - Virtual Keyboard commands -
