How to add to custom list view from user input?

Question

Im trying to add rows to a custom list view with user input, but I dont understand how to in the customadapter class..

The custom list view layout:

<TextView
    android:id="@+id/activityName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:layout_marginStart="28dp"
    android:layout_marginTop="22dp"
    android:textSize="35sp"
    android:text="Activity Name" />

<TextView
    android:id="@+id/xText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="19dp"
    android:text="x:"
    android:textSize="20sp"
    android:layout_below="@+id/activityName"
    android:layout_alignStart="@+id/activityName" />

<TextView
    android:id="@+id/yText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="y:"
    android:textSize="20sp"
    android:layout_alignBaseline="@+id/xText"
    android:layout_alignBottom="@+id/xText"
    android:layout_toEndOf="@+id/xText"
    android:layout_marginStart="32dp" />

<TextView
    android:id="@+id/zText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="z:"
    android:textSize="20sp"
    android:layout_marginEnd="119dp"
    android:layout_alignBaseline="@+id/yText"
    android:layout_alignBottom="@+id/yText"
    android:layout_alignParentEnd="true" />

I've managed to find some guides that show how to enter to a custom list view from arrays, but here I want it to be added from users input..

class CustomAdapter extends BaseAdapter{
    @Override
    public int getCount(){
        return 0;
    }
    @Override
    public Object getItem(int i)
    {
        return null;
    }
    @Override
    public long getItemId(int i)
    {
        return 0;
    }
    @Override
    public View getView(int i, View view, ViewGroup viewGroup)
    {
        view = getLayoutInflater().inflate(R.layout.customlistview, null);
        TextView activity_name = (TextView) view.findViewById(R.id.activityName);
        TextView x_text = (TextView) view.findViewById(R.id.xText);
        TextView y_text = (TextView) view.findViewById(R.id.yText);
        TextView z_text = (TextView) view.findViewById(R.id.zText);

    return view;
    }

}

Could someone help please?

To dynamically change a list or add or delete any list item, you should use an ArrayList.

Where is your ArrayList or Array where the listItems are stored? Please add every details.

You should use RecyclerView instead of ListView. It is more configurable and dynamic.
