Etaccount = (edittext) This.findviewbyid (r.id.sms_login_et_accout); 
Etaccount.setonclicklistener (this); 
Etaccount.setontouchlistener (New Ontouchlistener () { 
@Override public 
boolean Ontouch (View V, motionevent Event) { 
changescrollview (); 
return false; 
} 
}); 
/** 
* makes ScrollView point to bottom/ 
private void Changescrollview () { 
h.postdelayed (new Runnable () { 
@ Override public 
Void Run () { 
sl_center.scrollto (0, Sl_center.getheight ()); 
} 
Handler h = new Handler () {public 
void Handlemessage (msg) { 
};
