 AlertDialog.Builder builderSingle = new AlertDialog.Builder(YourActivity.this);

        List<Requests> requester = new ArrayList<>();
        final NameAdapter AlertDialogueAdapter = new NameAdapter(this, R.layout.your_custom_layout, requester);

        AlertDialogueBuilder.add(new Requests("Hello","StackOverF"))
        builderSingle.setIcon(R.drawable.avatar);
        builderSingle.setTitle("Select Message by,");
        builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
                finish();
            }
        });
        builderSingle.setAdapter(AlertDialogueAdapter, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Requests req = AlertDialogueAdapter.getItem(which);
                AlertDialog.Builder builderInner = new AlertDialog.Builder(ViewSpecialMessage.this);
                builderInner.setMessage(req.getKey());
                builderInner.setTitle(req.getName());
                builderInner.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog,int which) {
                        dialog.dismiss();
                    }
                });
                builderInner.show();
            }
        });
        builderSingle.show();

public class Requests{
    private String name;
    private String key;
    public Requests(){

    }
    public Requests(String name, String key){
        this.name = name;
        this.key = key;
    }

    public String getName() {
        return name;
    }

    public String getKey() {
        return key;
    }
}
public class NameAdapter extends ArrayAdapter<Requests>{

    public NameAdapter(Context context, int resource, List<Requests> objects) {
        super(context, resource, objects);
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = ((Activity) getContext()).getLayoutInflater().inflate(R.layout.name_adapter_layout, parent, false);
        }
        final Requests message = getItem(position);
        TextView NameOfRequester = (TextView) convertView.findViewById(R.id.RequesterName);
        ImageView ImgOfRequester = (ImageView) convertView.findViewById(R.id.RequesterImage);
        NameOfRequester.setText(message.getName());
        return convertView;
    }
}

You can try this

Create costom adapter by extending the class as ArrayAdapter(its in your case)

Override getView() function(also inflate the view).

After that you can directly set adapter by using

 builder.setAdapter(costomAdapter);
