android layout as emptyview of a listview programmatically made

Question

I have an Activity extends ListActivity, where I had to create a ListView programmatically (no xml).

To set up an emptyView for it the only way that worked was the following code I found in another thread:

    TextView emptyView = new TextView(this);
    ((ViewGroup) getListView().getParent()).addView(emptyView);
    getListView().setEmptyView(emptyView);

now my goal is to do the same using a layout instead of a TextView, so I made an xml with its id and put it this way:

    View emptyView = findViewById(R.id.empty_view_xml);
    ((ViewGroup) getListView().getParent()).addView(emptyView);
    getListView().setEmptyView(emptyView);

but it doesn't seem to work..

Your problem:

Because your view (empty_view_xml) doesn't exist in the activity xml, so calling findViewById(R.id.empty_view_xml); will return a null value, and setting null as emptyView will do nothing.

Your current code: .setEmptyView(emptyView); is similar to .setEmptyView(null);.

To solve this:

You need to inflate your custom xml, then add it as EmptyView:

LayoutInflater inflater = LayoutInflater.from(YourActivity.this);
View emptyView = inflater.inflate(R.layout.empty_view_xml, null, false);
((ViewGroup) getListView().getParent()).addView(emptyView);
getListView().setEmptyView(emptyView);
