问题 When using action bar tabs, sometimes they are displayed as "stacked" when tab content is too large for the display. A problem arises when I use a custom view for the tab content, it causes the selected tab to not be displayed in the dropdown, and once a tab is selected, the dropdown goes away, and small, empty tabs appear.

问题 I currently have a SearchView in my app's ActionBar (of which I am populating from an XML layout file) and I am trying to force it to only take numeric input. I've tried setting the android:inputType="number" attribute in XML, but it has no effect. Does anyone know the source of this problem?

I can set the collapseIcon (back arrow drawable) from xml: <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:layout_scrollFlags="enterAlways" app

问题 I'm trying to get my spinner working as the Action Bar Drop Down List item, but I cant seem to implement it at all, there aren't many tutorials for this after searching through Google. I think its something to do with the .setListNavigationCallbacks(); line of code, I just have no idea how to get this working from that line onwards. // setup action bar for spinner ActionBar bar = getActionBar(); bar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST); bar.setListNavigationCallbacks(); Spinner

问题 I'm trying to clear and close SearchView after entering a value. I found a solution but it closes the search and won't perform any action if I try to search again. @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main_actions, menu); searchView = (SearchView) menu.findItem(R.id.action_search).getActionView(); searchView.setOnQueryTextListener(searchListener); return super.onCreateOptionsMenu(menu); } SearchView.OnQueryTextListener

问题 I'm currently changing the view on my ActionBar MenuItem like so: MenuItem menuItem = menu.add(title); TextView tv = new TextView(context); tv.setTypeface(myTypeface); tv.setText("hello"); menuItem.setActionView(tv); However this disabled the function of the button, which I'm assuming is because I've changed the ActionView .
