I have generated a ListView using SimpleAdapter.I have 2 child RelativeLayouts inside a parent LinearLayout. I have made the layout with id colorful invisible initially.
I want to show this layout on clicking the listview row. I have done the following coding, but the problem with it is that no matter whichever row I click the layout colorful gets visible only on the first row and not on the row clicked.
Can anyone guide me step by step what to do? My codes are as below:
senttask.java
public class senttask extends Fragment {
public senttask() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.sentaskfragment, container,
false);
String font="font/Dosis-SemiBold.otf";
//String font2="font/Dosis-SemiBold.otf";
final Typeface tp=Typeface.createFromAsset(getActivity().getAssets(), font);
ListView sent=(ListView)view.findViewById(R.id.listViewtasksent);
final Databasehandler2 db=new Databasehandler2(getActivity().getApplicationContext());
HashMap<String, String> c=db.getAddedContacts();
String name=c.get("ph");
ArrayList<HashMap<String, String>>val=new ArrayList<HashMap<String,String>>();
val=db.getTaskSent(name);
ListAdapter k=new SimpleAdapter(getActivity(),val,R.layout.senttaskdata2,new String[]{"rname","heading","desc","id","path","receiver","sender"},new int[]{R.id.textView1,R.id.textView2,R.id.textView3,R.id.hide1,R.id.hide2,R.id.hide3,R.id.hide4})
{
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final View v = super.getView(position, convertView, parent);
TextView myname=(TextView)v.findViewById(R.id.textView1);
TextView mydes=(TextView)v.findViewById(R.id.textView2);
TextView mytopic=(TextView)v.findViewById(R.id.textView3);
myname.setTypeface(tp);
mydes.setTypeface(tp);
mytopic.setTypeface(tp);
return v;
}
};
sent.setAdapter(k);
sent.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
RelativeLayout r=(RelativeLayout)arg0.findViewById(R.id.colorful);
r.setVisibility(arg0.VISIBLE);
}
});
return view;
}
}

The lines:
RelativeLayout r=(RelativeLayout)arg0.findViewById(R.id.colorful);
r.setVisibility(arg0.VISIBLE);
will always reference the RelativeLayout from the first visible row of the ListView because arg0 represents the ListView(all rows end up with the same id so the first occurrence of the view with that id will be returned). Instead of looking for the target RelativeLayout in the entire ListView you'll need to look for it in the actual clicked row view which is also pass in that callback as the arg1 parameter. This way you'll have:
RelativeLayout r=(RelativeLayout)arg1.findViewById(R.id.colorful);
r.setVisibility(arg0.VISIBLE);
