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; } }
