Example 1 with ViewParent

use of android.view.ViewParent in project Launcher3 by chislon.

the class PagedView method focusableViewAvailable.

     * pass that along if it's on the current page.
     *
     * This happens when live folders requery, and if they're off page, they
     * end up calling requestFocus, which pulls it on page.

	 * Please note, you do <strong>not</strong> usually need to call this method
	 * yourself. Calling setEmptyView on the AdapterView will automatically call
	 * this method and set everything up. This includes when the Android
