Android: Inflate listview using its android:id [closed]

Answer 1

I think you may be confused about the difference between a component ID and a layout ID.

A layout ID refers to the name of a layout XML file. For example, if you have a layout named res/layout/home_activity.xml, its ID would be stored as R.layout.home_activity.

A component ID refers to the identity of a UI component inside an existing layout. So, inside your home_activity.xml layout you might have <TextView android:id="@+id/my_textview" />. The ID of that View is R.id.my_textview.

You can only inflate layouts using a layout ID. 'Inflating' a component ID doesn't make any sense, unless you inflate a layout as a child of a View with a specific ID.

Answer 2

Yes, the layout inflater inflates any View from the Resource id.

LayoutInflater inflater = (LayoutInflater)context.getSystemService
      (Context.LAYOUT_INFLATER_SERVICE);
listView = inflater.inflate(R.id.your_listview, parentView ); 

Edit: Well, it has to be a layout ID referring to some xml layout, not a component of it. Why don't you create a new xml containing that view component that you want to extract?

Answer 3

Now that things are more clear, I suggest that you set your 'Inflatable ListView' as gone in your Layout file using:

<ListView android:visibility="gone" ... />

Then just set it to visible using View.setVisibility() whenever you want it to 'inflate'

mHiddenListView.setVisibility(View.VISIBLE);
