Building a simple Group Chat View in Android -

i'm building simple online chat room app. have achieved below right now:

robert:blah.. tom: yes blah.. david(you): sounds cool! lily: know blah... robert:blah.. robert:blah.. david(you): wow! blah...  

the new feature/problem i'm facing want current user's talks show on right. below(this david see on screen):

robert:blah.. tom: yes blah..                                   sounds cool! : david(you) lily: know blah... robert:blah.. robert:blah..                                        wow! blah... : david(you) 

each line above textview, , i'm dynamically creating textview whenever there's new message, adding them linearlayout contains these textview. in order make david(current user)'s talk on right, tried set align right , change linearlayout relativelayout. realize once use relativelayout, talks in same line overlapping each other since didn't set height.. can shed light on how achieve please? codes below:

...     //new messages stored in lines[] (int = 0; < lines.length; i++) {      textview newline = new textview(getbasecontext());      newline.settext(lines[i]);      // check if speaker of line user himself                 if (speakername.equals(username)) {      //change layout of textview make align right..      }     mylinearview.addview(newline);//add linearview contains these talks  } 

you need use listview, chor waichun mentioned. however, way relative layout set relativelayout.layoutparams view rule sets layout_below previous view. in xml.

also, if insist on adding 1 view per line (which stated wrong, use listview), there's no reason not use linearlayout. can have linearlayout right justified text, set gravity right.
