问题 Is there any way to disable sliding animation of the NavigationDrawer's icon? I mean the effect, when you click the icon or open the Drawer with slide gesture. (I still use the ActionBar at the moment) Preview 回答1: You need to override the onDrawerSlide method of ActionBarDrawerToggle and set the slideOffset to 0 if the drawer is right drawer. So this would disable the animation of the navigation drawer image. @Override public void onDrawerSlide(View drawerView, float slideOffset) { if

I want the expandable listview to expand one of its groups and select one of its child by default when the activity opens up. The user may change the selection according to his requirement. Whatever I have created is not satisfying my requirement. The expandable list is allowing the user to select multiple options. The MainActivity : public class MainActivity extends Activity { DrawerLayout mDrawerLayout;

问题 I've implemented a DrawerLayout with this tutorial and everything works fine. @Override public boolean onPrepareOptionsMenu(Menu menu) { // if nav drawer is opened, hide the action items boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); menu.findItem(R.id.action_settings).setVisible(!drawerOpen); return super.onPrepareOptionsMenu(menu); } onPrepareOptionsMenu simply toggles the menu visibility in one shot.

问题 I have a hard time trying to come with a good and acceptable layout for an activity for a tablet , but I'm not sure that if my design is compatible with Google's design guidelines.

问题 The Android app I'm working on has a single MainActivity and each screen of the app is implemented as a Fragment. Each fragment is instantiated like this in the MainActivity as a private class variable: public class MainActivity extends Activity implements MainStateListener { private FragmentManager fm = getFragmentManager(); private BrowseFragment browseFragment = BrowseFragment.newInstance(); ... There is a single 'fragment frame' that loads each screen fragment. When switching screens in
