How to Display Two ArrayList values in Android ListView?

Question

I am New Android development. In My application I have two ArrayLists.

One ArrayList contains HashTbale. Another one contains HashTable

Now How can i set adpter and how to show in Listview image from Second ArrayList and Text From from ArrayList in ListView Row.

I am not able to get exact solution .

Please any one help in this issue.

Thanks in advance

if possible then give more detail of both the HashMap values. If possible i can suggest you to merge them into a single hashmap. Easy to handle. — Paresh Mayani

Just use HashMap arraylist which store both Image path and your text and set that single ArrayList to your Adapter. Also you can make a Custom Object ArrayList for your requirement. Just google you can find many examples.. — user370305

If you want to display image and text in each row and if you are using 2 arraylist for the same then here is the solutions. Try this

List<Integer> imageList = getImageList();  //list of drawable ids
List<String> values = getValues();

class CustomAdapter extends BaseAdapter {

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return imageList.size();;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // inflate the layout which contains imageview and textview which are aligned horizontally. 
        //Assuming you inflated layout and got imageView and textview from that layout
        textView.setText(values.get(position));

        imageView.setImageResource(imageList.get(position));
        return convertView;
    }

}

//Code wont work if you directly copy paste. Use the logic and change accordingly

Instead of using 2 arraylist, my suggestion is you use HashMap. Imagepath as key and text as value.

@PareshMayani i agree. But he wanted to use 2 arraylists. so only i gave this solution

user370305 Over a year ago

what about if both arraylist has a different size. Or Text and Image are not related to each-other?

1st Suggestion: (Not proposed)

Do you know how to define Custom adapter for ListView? If yes then you can easily pass two arraylist to your custom adapter. And inside getView() method, you can display whatever details you wants in ListView

2nd Suggestion: (Proposed solution)

If You make one ArrayList of CustomObject then there is no need to pass two ArrayList in Adapter.

1st suggestion not works if both arraylist has a different size. Or Text and Image are not related to each-other.
