ActionBar SearchView not fully expanding in landscape mode

Question

When using the action bar search interface, the widget expands to occupy the full width of the screen in portrait mode, but stops short in landscape mode.

Is there a way to set the expansion layout params on the SearchView to fully fill the action bar when the user is typing a search?

See image:

Note: I'm not currently using ActionBar Sherlock

Edit: Here's what I did to get it to extend the full width.

searchView.setOnSearchClickListener(new OnClickListener() {
    private boolean extended = false;

    @Override
    public void onClick(View v) {
        if (!extended) {
            extended = true;
            LayoutParams lp = v.getLayoutParams();
            lp.width = LayoutParams.MATCH_PARENT;
        }
    }

});

Answer 1

MenuItemCompat's SearchView has a property named maxWidth.

    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchView.setMaxWidth(xxx);

use screen width instead of xxx offcourse

Did you try something like that?

editView.setOnKeyListener(new OnKeyListener() {
    private boolean extended = false;

    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (!extended && event.getAction() == KeyEvent.ACTION_DOWN) {
            extended = true;
            LayoutParams lp = v.getLayoutParams();
            lp.width = LayoutParams.MATCH_PARENT;
        }

        return false;
    }

});
