Modify textview of parent layout from adapter xamarin android

Sorry, I'm using google translate.
Hello, I am developing an application in xamarin android with visual studio 2017 to take requests where I send information from a fragment to a List<EN_WishDetail> to store the selection of items and this is dumped to an adapter to display it in another fragment.
my problem is that the parent layout loads a custom listview where I have 2 buttons to increase and decrease the quantities of the items this works correctly, likewise in the parent layout it has two textviews to count the number of items and the total value of the order , I want that when increasing the amount this also updates the textview of the parent layout from the adapter where the button functions are.
How can I access the parent layout from the adapter and modify its value.

I hope you can guide me the way to follow, thanks for your time.

Yes, you can use event to achieve this just as ToolmakerSteve mentioned.
I made a simple demo to pass a int parameter to the main page, you can refer to the following code:
1.in your Adapter,define variable MyEvent:
public class WishAdapter : BaseAdapter<EN_WishDetalle>
{
// add EventHandler here
public event EventHandler<int> MyEvent;
//other code
public WishAdapter(Context context, List<EN_WishDetalle> list)
{
sList = list;
sContext = context;
}
//other code
}
2.in method GetView of class WishAdapter , add code for button buttonMax:
holder.buttonMax.Click += delegate
{
// other code
// invoke here
MyEvent?.Invoke(this, 1);
};
3.In WishFragment,do like this:
adapter = new WishAdapter(Activity, List_Wish);
WishlistView.Adapter = adapter;
adapter.MyEvent += Adapter_MyEvent;
And method Adapter_MyEvent is:
private void Adapter_MyEvent(object sender, int e)
{ // here we can get the passed parameter e
Debug.WriteLine("The passed parameter : " + e);
}

Show fragment recyclerViews in Parent Activity

I am simply trying to show a fragments recyclerView inside it's parent activity. The data is there but nothing is showing up. Any thoughts? Here is PagerAdapter, parent and fragment classes with xmls so that all the parts are available to see. I want the RV to fit right here between the CardView and comment line. Thanks for any help!

Thanks again!

While your RelativeLayout(the one just before the ListView) have match_parent as height, it will take the remaining space of the window... so there is no place for your ListView to be shown.

Try this..
Give id to the above Relative layout and use the same below.
<ListView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="vertical"
android:layout_below="#id/"
android:id="#+id/list_cart_view">
</ListView>

ListView in a Popup with EditText Issue in Android

I am having an issue with scrolling of ListView in a Popup. I have an activity that has a dialog theme so that it can open up as a popup. The Popup should contain EditText at the bottom and the remaining area above it should be the ListView. When the activity is started it should start with keypad open & focus on EditText.
Issue: ListView doesn't scroll when keypad is open.
Below is my activity code:
public class CommentsActivity extends Activity{
private InputMethodManager imm;
private String commentCount;
private ShopPirateDatabase db;
private ArrayList<CommentsBean> commentsList = new ArrayList<CommentsBean>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.comments_layout);
imm = (InputMethodManager) this
.getSystemService(Context.INPUT_METHOD_SERVICE);
db=new ShopPirateDatabase(this);
if(getIntent().hasExtra("count")){
commentCount=getIntent().getExtras().getString("count");
}
ListView lvMyComments=(ListView)findViewById(R.id.lvMyComments);
lvMyComments.setVisibility(View.GONE);
final Button btnPost=(Button)findViewById(R.id.btnPost);
btnPost.setVisibility(View.GONE);
etAddComment=(EditText)findViewById(R.id.etAddComment);
RelativeLayout progressLayout=(RelativeLayout)findViewById(R.id.progressLayout);
progressLayout.setVisibility(View.VISIBLE);
TextView tvNoComments=(TextView)findViewById(R.id.tvNoComments);

if(Integer.parseInt(commentCount) > 0){
getCommentsFromDb();
if(commentsList!=null && commentsList.size() > 0){
progressLayout.setVisibility(View.GONE);
tvNoComments.setVisibility(View.GONE);
lvMyComments.setVisibility(View.VISIBLE);

lvMyComments.setAdapter(commentsAdapter);
}
} else{

I am not sure about your code, its too tedious to go through. But i have had the same problems before and I solved it as follows. In your adapter you need to set the on click listener for that button and add a tag to it.
holder.btnList.setOnClickListener(((MyActivity) context));
Where context is the Context that you pass to the adapter and the MyActivity is whatever activity in which the click is to be handled. So when you click the button then the MyActivity's on click listener will be called. You can also add tags to the holder object if you want any data to be passed. Then in your MyActivity where you implement the onClickListener. You handle whatever events you want in the MyActivity. Please post further doubts if you have any.

holder.btnList.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v){
//youre code
}
);
