在另一个微调器中选择选项时隐藏Edittext或Spinner

Question

Basically I want to show only spinner or Edittext upon selecting a specific option in another spinner. There is a Spinner(@+id/selection) with two options as standard and custom. When user selects standard, Spinner(@+id/duration) should be visible below that. Just like that when user select custom, Edittext(@+id/custom_duration) should be visible in the next step. Always there should be only one option visible upon selecting a option in first spinner(@+id/selection). After some research I came close to a solution. But Im not sure how to proceed further. please help. This is my current code:

XML file

  <Spinner
                android:id="@+id/selection"
                android:layout_width="0dp"
                android:layout_height="45dp"
                android:layout_marginStart="25dp"
                android:layout_marginTop="8dp"
                android:layout_marginEnd="32dp"
                android:entries="@array/selection"
                android:minWidth="140dp"
                android:padding="10dp"
                android:spinnerMode="dialog"

                />


            <Spinner
                android:id="@+id/duration"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginStart="32dp"
                android:layout_marginTop="8dp"
                android:layout_marginEnd="32dp"
                android:entries="@array/session_duration_labels"
                android:minWidth="140dp"
                android:padding="10dp"
                android:spinnerMode="dialog"/>

            <EditText
                android:id="@+id/custom_duration"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginStart="32dp"
                android:layout_marginTop="8dp"
                android:layout_marginEnd="32dp"
                android:minEms="6"
                app:layout_row="0"/>

                // put your code here for weight spinner
                if (position == 2) {

                }

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });
    }

}

You don't need to set listener twice to same spinner. You instead can check two different conditions in same listener, Keep only one listener and remove another one. change your code as follows.

 spinner_session_selection.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
     @Override
     public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            if (position == 1) {
                edit_custom_duration.setVisibility(View.GONE);
            } else {
                edit_custom_duration.setVisibility(View.VISIBLE);
            }

            if (position == 2) {
                spinner_session_duration.setVisibility(View.GONE);
            } else {
                spinner_session_duration.setVisibility(View.VISIBLE);
            }


        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }

    });
