Joseph :
I created a List of String Array in the strings.xml so it can then be used in and Adapter, but I don't want the array stored in the string to be set as new-descriptive text when a listItemClick opens to a new activity. Please help me. I want to create another list of array as full-description which should be different from the one tied to the row.
Let me describe what I mean furthermore.
My row.xml shows an Image, TextView as Title, & another TextView as description. Now i have used this arrangement to generate constructor and getters for my Model.java
Now, if I click on a list of ListView items, it opens to a NewActivity.java there by feeding its data stored in string.xml as arrayList which is simply Title & description texts. But I want another text different from that discription to show in that NewActivity.java as brand-new-descrption text. That is what I'm struggling to do now.
Thanks
this is the MainActivity.java code

rahul khurana :
Add it to your Model as attribute
class Model{
your variable
.
.
.
String brandNewDesc;
public String getBrandNewDesc(){
return brandNewDesc;
}
public void setBrandNewDesc(String description){
brandNewDesc =description;
}
}
and use
//listview item clicks
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//code later
Intent intent = new Intent(mContext, NewActivity.class);
intent.putExtra("position", getViewTypeCount());
intent.putExtra("actionBarTitle", modellist.get(i).getTitle());
intent.putExtra("contentTv", modellist.get(i).getDesc());
**intent.putExtra("brandNewDesc", modellist.get(i).getBrandNewDesc());**
mContext.startActivity(intent);
}
});
