The * ActionBarDrawerToggle facilitates this behavior. * Items within the drawer should fall into one of two categories:</p> * <p/> * <ul> * <li><strong>View switches</strong>. A view switch follows the same basic policies as * list or tab navigation in that a view switch does not create navigation history. * This pattern should only be used at the root activity of a task, leaving some form * of Up navigation active for activities further down the navigation hierarchy.</li> * <li><strong>Selective Up</strong>. The drawer allows the user to choose an alternate * parent for Up navigation. This allows a user to jump across an app's navigation * hierarchy at will. The application should treat this as it treats Up navigation from * a different task, replacing the current task stack using TaskStackBuilder or similar. * This is the only form of navigation drawer that should be used outside of the root * activity of a task.</li> * </ul> * <p/> * <p>Right side drawers should be used for actions, not navigation. This follows the pattern * established by the Action Bar that navigation should be to the left and actions to the right. * An action should be an operation performed on the current contents of the window, * for example enabling or disabling a data overlay on top of the current content.</p> */ public class MainActivity extends Activity { private DrawerLayout mDrawerLayout; private ListView mDrawerList; private NavDrawerListAdapter mAdapter; private ActionBarDrawerToggle mDrawerToggle; private String[] mNavMenuTitles; private TypedArray mNavMenuIconsTypeArray; private ArrayList<NavDrawerItem> mNavDrawerItems; private CharSequence mDrawerTitle; private CharSequence mTitle; private String[] mPlanetTitles; private void setCustomActionBar() { ActionBar actionBar = getActionBar(); if(actionBar != null) { View view = getLayoutInflater().inflate(R.layout.action_bar, null); /*TextView title = (TextView)view.findViewById(android.R.id.title); if(!TextUtils.isEmpty(getShowTitle())) { title.setText(getShowTitle()); }*/ View back = view.findViewById(R.id.btn_back); View option = view.findViewById(R.id.btn_option); back.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub // finish(); boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); if(drawerOpen) { mDrawerLayout.closeDrawer(mDrawerList); } else { mDrawerLayout.openDrawer(mDrawerList); } } }); option.setVisibility(View.GONE); ActionBar.LayoutParams lp = new ActionBar.LayoutParams( ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT, Gravity.CENTER); actionBar.setCustomView(view, lp); // actionBar.setDisplayShowHomeEnabled(false); // actionBar.setDisplayShowTitleEnabled(false); actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM); // actionBar.setDisplayShowCustomEnabled(true); } } @Override public void setTitle(CharSequence title) { // TODO Auto-generated method stub mTitle = title; ActionBar actionBar = getActionBar(); if(actionBar != null) { View view = actionBar.getCustomView(); ((TextView)view.findViewById(android.R.id.title)).setText(title); } } @Override public void setTitle(int titleId) { // TODO Auto-generated method stub setTitle(getText(titleId)); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); setCustomActionBar(); mTitle = mDrawerTitle = getTitle(); mPlanetTitles = getResources().getStringArray(R.array.nav_drawer_items); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mNavDrawerItems = new ArrayList<NavDrawerItem>(); mNavMenuTitles = getResources().getStringArray(R.array.nav_drawer_items); // nav drawer icons from resources mNavMenuIconsTypeArray = getResources() .obtainTypedArray(R.array.nav_drawer_icons); // adding nav drawer items to array // Home mNavDrawerItems.add(new NavDrawerItem(mNavMenuTitles[0], mNavMenuIconsTypeArray .getResourceId(0, -1))); // Find People mNavDrawerItems.add(new NavDrawerItem(mNavMenuTitles[1], mNavMenuIconsTypeArray .getResourceId(1, -1))); // Photos mNavDrawerItems.add(new NavDrawerItem(mNavMenuTitles[2], mNavMenuIconsTypeArray .getResourceId(2, -1))); // Communities, Will add a counter here mNavDrawerItems.add(new NavDrawerItem(mNavMenuTitles[3], mNavMenuIconsTypeArray .getResourceId(3, -1))); // Pages mNavDrawerItems.add(new NavDrawerItem(mNavMenuTitles[4], mNavMenuIconsTypeArray .getResourceId(4, -1))); mDrawerList = (ListView) findViewById(R.id.left_drawer); mAdapter = new NavDrawerListAdapter(this, mNavDrawerItems); // set a custom shadow that overlays the main content when the drawer opens mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); // set up the drawer's list view with items and click listener mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPlanetTitles)); mDrawerList.setAdapter(mAdapter); mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); // enable ActionBar app icon to behave as action to toggle nav drawer // getActionBar().setDisplayHomeAsUpEnabled(true); // getActionBar().setHomeButtonEnabled(true); // ActionBarDrawerToggle ties together the the proper interactions // between the sliding drawer and the action bar app icon mDrawerToggle = new ActionBarDrawerToggle( this, /* host Activity */ mDrawerLayout, /* DrawerLayout object */ R.drawable.ic_drawer, /*
