How to display the data in table view in android eclipse - 


public void showdata(view view)     {         cursor c = db.rawquery("select * student2", null);         int count = c.getcount();         c.movetofirst();         tablelayout tablelayout = new tablelayout(getapplicationcontext());         tablelayout.setverticalscrollbarenabled(true);         tablerow tablerow;         textview textview, textview1, textview3, textview5;         tablerow = new tablerow(getapplicationcontext());          textview = new textview(getapplicationcontext());         textview.settext("name");         textview.settextcolor(color.red);         textview.settypeface(null, typeface.bold);         textview.setpadding(20, 20, 20, 20);         tablerow.addview(textview);           textview5 = new textview(getapplicationcontext());         textview5.settext("email");         textview5.settextcolor(color.red);         textview5.settypeface(null, typeface.bold);         textview5.setpadding(20, 20, 20, 20);         tablerow.addview(textview5);         tablelayout.addview(tablerow);          for(integer j=0; j< count; j++)         {             tablerow = new tablerow(getapplicationcontext());              textview1 = new textview(getapplicationcontext());             textview1.settext(c.getstring(c.getcolumnindex(name)));               textview3 = new textview(getapplicationcontext());             textview3.settext(c.getstring(c.getcolumnindex(email)));              textview1.setpadding(20, 20, 20, 20);             textview3.setpadding(20, 20, 20, 20);              tablerow.addview(textview1);             tablerow.addview(textview3);              tablelayout.addview(tablerow);             c.movetonext();         }         setcontentview(tablelayout);         db.close();     }

i've tested code dummy students, working fine me.

please verify getting students iterating cursor. put log.d("tag","some_student") testing

also, should use youractivityname.this in place of getapplicationcontext(). example 

tablerow = new tablerow(this);

full code using dummy students

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
