Answer 1

Use custom layout dialog to add your custom layout to dialog. Try using below given code. Hope this will be a helpful answer.

final Dialog dialog = new Dialog(getApplicationContext(), R.style.FullHeightDialog);

    dialog.setContentView(R.layout.reclycer_data);
    dialog.setCancelable(false);

    if (dialog.getWindow() != null){
        dialog.getWindow().setLayout(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    }

    RecyclerView list = dialog.findViewById(R.id.recView);
    list.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
    list.setAdapter(adapter);

dialog.show();

• Define dialog style in style.xml

   <style name="FullHeightDialog" parent="Base.Theme.AppCompat.Light.Dialog"> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowFrame">@null</item> <item name="android:windowFullscreen">true</item> </style> 

Answer 2

Dialog context must Activity

    final AlertDialog.Builder mBuilder = new AlertDialog.Builder(YouActivity.this);
    mBuilder.setTitle("Location Available!");
    LayoutInflater inflater = getLayoutInflater();
    View convertView = inflater.inflate(R.layout.reclycer_data, null);

    RecyclerView list = convertView.findViewById(R.id.recView);
    list.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
    list.setAdapter(adapter);
    mBuilder.setView(convertView); // setView

    AlertDialog dialog = mBuilder.create();
    dialog.show();
