Can we use listview for heterogeneous collections

Question

I need to create a feed screen like facebook application where I will fetch data from api and each row has different size of images and text. I know ScrollView is for both homogeneous and heterogeneous collection and listView is for only homogeneous collection but can I use listview for heterogeneous collections for feed. ?

Well i am using react native and custom adapter does not exist in react-native. my question is that is it possible? if it is then react-native definitely support for this. — Waleed Arshad, Aug 01 '16 at 09:21
It's almost like a top google hit. Word for word. https://github.com/codepath/android_guides/wiki/Implementing-a-Heterogenous-ListView — OneCricketeer, Aug 02 '16 at 07:14
@waleedarshadmuhammadarshad you can easily do this with recyclerView with different type https://guides.codepath.com/android/Heterogenous-Layouts-inside-RecyclerView — Amir, Aug 02 '16 at 12:07

You can try something like this:

private List mList = new ArrayList();

mList.add("String");
mList.add('A');
mList.add(true);

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ......
    ......
    ......
    if(mList.get(position) instanceof String){

    }else if(mList.get(position) instanceof Character){

    }else if(mList.get(position) instanceof Boolean){

    }
}

@Override
public int getItemViewType(int position) {
    if(mList.get(position) instanceof String){
        return 0;
    }else if(mList.get(position) instanceof Character){
        return 1;
    }else if(mList.get(position) instanceof Boolean){
        return 2;
    }
    return 0;
}

Or normalize them into a common Class.
