Android Studio Add text view on button click

Question

So i'm trying to create a java app for tracking orders, and I need each button to create a view in an ordered list currently i'm just trying to get the first button to add information but it isn't doing anything. Any help would be appreciated as I am very new to android programming.

Section of code in activity main that contains the linear layout and button i want to be able to add views

 <Button android:id="@+id/add_funnel_cake" android:layout_width="90dp" android:layout_height="80dp" android:layout_marginLeft="15dp" android:layout_marginTop="10dp" android:paddingRight="10dp" android:text="Funnel Cake"></Button>

Layout resource file with view i want to add

<TextView android:id="@+id/funnelItem" android:layout_width="387dp" android:layout_height="40dp" android:background="@color/cardview_dark_background" android:text="Funnel Cake" android:textColor="@color/cardview_light_background" android:textSize="25dp"></TextView>

Section of code within MainActivity for functionality

public class MainActivity extends AppCompatActivity implements View.OnClickListener { LinearLayout orderList; Button buttonFunnel; Button buttonOreo; Button buttonTwinkie; Button buttonSnicker;

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); orderList = findViewById(R.id.Order_List); buttonFunnel = findViewById(R.id.add_funnel_cake); buttonFunnel.setOnClickListener(this); } @Override public void onClick(View v){ addFunnelCake(); } private void addFunnelCake(){ View funnel = getLayoutInflater().inflate(R.layout.funnel_cake_row, null, false); TextView funnelCake = (TextView)funnel.findViewById(R.id.funnelItem); /* ImageView closeItem = (ImageView)funnel.findViewById(R.id.remove_item); */ orderList.addView(funnel); }

I think you need to inflate the View you want to add differently.

View inflatedView = View.inflate(context, yourViewXML, null); //use null to not add View to parent
