setContentView(R.layout.ticket);
t1=(TextView)findViewById(R.id.textView3);
t2=(TextView)findViewById(R.id.textView5);
l1=(ListView)findViewById(R.id.listView1);
//Get the Table no Value From Edit Text
Intent i1=getIntent();
Bundle b=i1.getExtras();
int num=b.getInt("Table No:");
String pno=Integer.toString(num);
t1.setText(pno);
//Get The Guest Value From Edit Text
Intent i2=getIntent();
Bundle b1=i2.getExtras();
int num1=b1.getInt("Guest:");
String pno1=Integer.toString(num1);
t2.setText(pno1);
l1.setAdapter(new EfficientAdapter(TicketActivity.this));
}
private static class EfficientAdapter extends BaseAdapter{
private LayoutInflater mInflater;
public EfficientAdapter(Context context){
mInflater=LayoutInflater.from(context);
// implementation of EfficientAdapter

Thanks in Advance;
make sure, HomeActivity.select1.length, and GlobalClass.myval.size() and GlobalClass.myvals.size() are of same size.
I am editing your answer, please make a note its just a workaround, coz to get a proper solution I need to understand these data sources well.
