I have action bar with one icon:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/is_connected"
android:icon="#drawable/ic_disconnected"
android:title="#string/general_disconnected"
app:showAsAction="always"/>
When I change that icon in this way:
mActionBarMenu.getItem(0).setIcon(getResources().getDrawable(R.drawable.ic_connected));
and open navigation drawer that that item icon change to initial state ang again is: #drawable/ic_disconnected
It is possible to avoid that?
UPDATE:
private void setupDrawer() {
mDrawerList = (ListView) findViewById(R.id.navList);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mActivityTitle = getTitle().toString();
addDrawerItem();
mActionBar.setDisplayHomeAsUpEnabled(true);
mActionBar.setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
//getSupportActionBar().setTitle("Menu");
invalidateOptionsMenu();
}
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu();
}
};
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.setDrawerListener(mDrawerToggle);
}

I'm currently struggling with the DrawerLayout animation doing weird stuff; The hamburger icon is laggy and often switch from hamburger to arrow without animation if I don't put an Handler to delay the fragment transaction animation.
So I ended up putting an handler to wait until the hamburger icon perform the animation but it just doesn't feel natural that we need to wait until the drawer close to switch fragment. I'm sure there is a better way to handle this...
Here is how I do currently:
private void selectProfilFragment() {
final BackHandledFragment fragment;
// TODO test this again
Bundle bundle = new Bundle();
bundle.putString(FragmentUserProfile.USER_FIRST_NAME, user.getFirstname());
bundle.putString(FragmentUserProfile.USER_LAST_NAME, user.getLastname());
bundle.putString(FragmentUserProfile.USER_PICTURE, user.getProfilepic());
bundle.putString(FragmentUserProfile.USER_EMAIL, user.getEmail());
bundle.putBoolean(FragmentUserProfile.USER_SECURITY, user.getParameters().getSecuritymodule().equals("YES"));
fragment = new FragmentUserProfile();
fragment.setArguments(bundle);
mDrawerLayout.closeDrawer(mDrawerLinear);
new Handler().postDelayed(new Runnable() {
public void run() {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.pull_in_right, R.anim.push_out_left, R.anim.pull_in_left, R.anim.push_out_right);
ft.replace(R.id.content_frame, fragment)
.addToBackStack(fragment.getTagText())
.commitAllowingStateLoss();
}
}, 300);
}
It's still glitching a little bit in between the DrawerLayout closing and opening fragment transaction animation.
Here is How I instanciate the drawer:
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerListChild.setAdapter(new DrawerListAdapter(this, R.layout.drawer_layout_item, mPlanTitles));
mDrawerListChild.setOnItemClickListener(new DrawerItemClickListener());
mProfilPic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
selectProfilFragment();
}
});
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
toolbar,
R.string.drawer_open,
R.string.drawer_close
) {
public void onDrawerClosed(View view) {
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
invalidateOptionsMenu();
}
};
getSupportFragmentManager().addOnBackStackChangedListener(mOnBackStackChangedListener);
mDrawerLayout.setDrawerListener(mDrawerToggle);
setSupportActionBar(toolbar);
I am not sure what causing this behavior though I want to draw your attention on few thing.
I am not aware which ActionBarDrawerToggle class you are using but preferable to use android.support.v7.app.ActionBarDrawerToggle instead of android.support.v4.app.ActionBarDrawerToggle as it is deprecated.
Use addDrawerListener() instead of setDrawerListener() as it is deprecated.
Use spinBars and set value true to rotate bars during transition.
e.x. in your styles.xml as described here.
In onDrawerClosed and onDrawerOpened call syncState(). Also call this method on your ActionBarDrawerToggle. Check this.
Hope this will help you.
Heres how you can do it. In the Activity containing fragment setup your drawer.
public void setupDrawer(){
NavigationFragment drawerFragment = (NavigationFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
mActionbarToggle = drawerFragment.setUp(R.id.navigation_drawer, mDrawerLayout, mToolbar);
}
Now in the NavigationDrawerFragment define your setUp method
public ActionBarDrawerToggle setUp(int navigation_drawer, DrawerLayout drawerLayout, Toolbar mToolbar) {
mFragmentContainerView = getActivity().findViewById(navigation_drawer);
this.mDrawerLayout = drawerLayout;
//mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), drawerLayout, mToolbar, R.string.drawer_open, R.string.drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (!isAdded()) {
return;
}
getActivity().supportInvalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!isAdded()) {
return;
}
getActivity().supportInvalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
};
mDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
((MainActivity) mContext).onBackPress();
}
});
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
return mDrawerToggle;
}
That's it, your drawer is completely setUp.
After I implemented a Navigation Drawer my up Arrow for up Navigation disappeared.
mDrawerList = (ListView) findViewById(R.id.navList);
addDrawerItems();
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
});
mDrawerLayout = (DrawerLayout) findViewById(R.id.project_drawer);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, android.R.color.transparent, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
mSlideState = true;
invalidateOptionsMenu();
}
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
mSlideState = false;
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
I've set the parentActivity in AndroidManifest too:
<activity
android:name=".Activity2"
android:label="#string/projects"
android:icon="#android:color/transparent"
android:parentActivityName=".Activity1">
Does it have to do with the android.R.color.transparent in the ActionBarDrawerToogle?
Note: I set a MenuItem to open/close the Navigation Drawer. THats the reason why I set android.R.color.transparent.
Now just the Activity label appears.
What did I do wrong?
Kind Regards!
I am implementing ActionTogglebutton to show drawer.though drawer are showing on click of toggle button but image or nothing is shown on toggle button position
Here is my code
actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer, R.drawable.kooveicon) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(getTitle());
getActionBar().setDisplayShowHomeEnabled(false);
getActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Closed");
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Browse Items");
invalidateOptionsMenu();
}
};
Update your code exactly like below:
actionBar = getSupportActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.my_drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.setDrawerListener(mDrawerToggle);
and add another method onPostCreate() in your class [this is drawer indicator animation]
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
Hope this helped!
I am having trouble with changing my navigation drawer icon to a custom one. I've currently had to implement the standard drawer icon which has 3 horizontal lines on top, but now I want to replace this with my custom drawer icon.
This is how my mDrawerToggle is at the moment:
mDrawerToggle=new ActionBarDrawerToggle(this,
mDrawerLayout,
R.drawable.app_icon,
R.string.drawer_open) {
// My code
};
Use below code,it's working for V7 ActionBarDrawerToggle
mDrawerToggle.setDrawerIndicatorEnabled(false);
mDrawerToggle.setHomeAsUpIndicator(R.drawable.your_custom_icon);
mDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mDrawerLayout.isDrawerVisible(GravityCompat.START)) {
mDrawerLayout.closeDrawer(GravityCompat.START);
} else {
mDrawerLayout.openDrawer(GravityCompat.START);
}
}
});
Here is the sample code taken from
Creating a Navigation Drawer
Activity.class
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
...
public void onCreate(Bundle savedInstanceState) {
...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle your other action bar items...
return super.onOptionsItemSelected(item);
}
...
}
This is main activity
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
toggle.setDrawerIndicatorEnabled(false);
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
drawer.openDrawer(GravityCompat.START);
}
});
toggle.setHomeAsUpIndicator(R.drawable.menuicon);
You could use this format for your mDrawerToggle:
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.CUSTOM_ICON, // Navigation menu toggle icon
R.string.DRAWER_OPEN, // Navigation drawer open description
R.string.DRAWER_CLOSE // Navigation drawer close description
)
Change your drawable and make sure it is the same name as the one in the code.
This is the main layout file
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/white"
android:choiceMode="singleChoice"
android:divider="#color/black"
android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
This is the main Activity
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.menuicon, // nav menu toggle icon
R.string.app_name, // nav drawer open - description for
// accessibility
R.string.app_name // nav drawer close - description for
// accessibility
) {
public void onDrawerClosed(View view) {
// getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
// getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
finally at R.drawable.menuicon(you can give your image id) it will work.
I had standart navigation drawer, but now i'm trying to modify it, using toolbar.
Earlier my code looked like:
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.v("MAIN", "CREATE");
initViews();
setListeners();
getFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
shouldDisplayHomeUp();
}
});
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
NavigationDrawerFragment.java
public void setUp(int fragmentId, DrawerLayout drawerLayout) {
mFragmentContainerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
((MainActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((MainActivity) getActivity()).getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), mDrawerLayout,
((MainActivity) getActivity()).getToolbar(),
R.string.navigation_drawer_open,
R.string.navigation_drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (!isAdded()) {
return;
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!isAdded()) {
return;
}
if (!mUserLearnedDrawer) {
// The user manually opened the drawer; store this flag to prevent auto-showing
// the navigation drawer automatically in the future.
mUserLearnedDrawer = true;
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).apply();
}
if (mDrawerListView != null) {
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
}
};
// If the user hasn't 'learned' about the drawer, open it to introduce them to the drawer,
// per the navigation drawer design guidelines.
if (!mUserLearnedDrawer && !mFromSavedInstanceState) {
mDrawerLayout.openDrawer(mFragmentContainerView);
}
// Defer code dependent on restoration of previous instance state.
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
Now i modified my code:
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mToolbar = (Toolbar) findViewById(R.id.toolbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
initViews();
setListeners();
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
shouldDisplayHomeUp();
getFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
mBackCount++;
shouldDisplayHomeUp();
}
});
}
NavigationDrawerFragment.java
public void setUp(int fragmentId, DrawerLayout drawerLayout) {
mFragmentContainerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), mDrawerLayout,
((MainActivity) getActivity()).getToolbar(),
R.string.navigation_drawer_open,
R.string.navigation_drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (!isAdded()) {
return;
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!isAdded()) {
return;
}
if (!mUserLearnedDrawer) {
// The user manually opened the drawer; store this flag to prevent auto-showing
// the navigation drawer automatically in the future.
mUserLearnedDrawer = true;
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).apply();
}
if (mDrawerListView != null) {
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
}
};
// If the user hasn't 'learned' about the drawer, open it to introduce them to the drawer,
// per the navigation drawer design guidelines.
if (!mUserLearnedDrawer && !mFromSavedInstanceState) {
mDrawerLayout.openDrawer(mFragmentContainerView);
}
// Defer code dependent on restoration of previous instance state.
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
And shouldDisplayHomeUp function:
public void shouldDisplayHomeUp (){
boolean canBack = getFragmentManager().getBackStackEntryCount() > 0;
mNavigationDrawerFragment.getDrawerToggle().setDrawerIndicatorEnabled(!canBack);
}
But the back arrow is not shown
I tried call
getSupportActionBar().setDisplayHomeAsUpEnabled(canBack);
getSupportActionBar().setHomeButtonEnabled(canBack);
So the back arrow appers but clicking on it has no effect
From the docs:
To allow Up navigation with the app icon in the action bar, call
setDisplayHomeAsUpEnabled():
#Override public void onCreate(Bundle savedInstanceState) {
...
getActionBar().setDisplayHomeAsUpEnabled(true); }
This adds a left-facing caret alongside the app icon and enables it as an action
button such that when the user presses it, your activity receives a
call to onOptionsItemSelected(). The ID for the action is
android.R.id.home.
This means that you will have to implement your back routine on onOptionsItemSelected and check for R.id.home. To avoid calling the routine when you click on the hamburger menu check for canback too on onOptionsItemSelected.
http://developer.android.com/training/implementing-navigation/ancestral.html#up
EDIT
To archieve what you want you will have to implement your own navigation routine.
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(shouldBack()) {
//call onbackpressed or something
if(displayBackAgain)
return; //return after so you don't call syncState();
}else if (mNavigationDrawerFragment.isDrawerOpen())
mNavigationDrawerFragment.closeDrawer();
else
mNavigationDrawerFragment.openDrawer();
mNavigationDrawerFragment.getActionBarDrawerToggle().syncState();
}
});
}
To enable the backbutton icon just call getSupportActionBar().setDisplayHomeAsUpEnabled(true); to disable it just call mNavigationDrawerFragment.getActionBarDrawerToggle().syncState();
I found a way to control the back button and the nav. It worked with me.
First , set up:
private void setupNav () {
this.toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(this.toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
this.mActionBarDrawerToggle = new ActionBarDrawerToggle(this, this.mDrawerLayout, this.toolbar, 0, 0);
this.mActionBarDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//catch back button here.
}
});
this.mDrawerLayout.setDrawerListener(this.mActionBarDrawerToggle);
this.mActionBarDrawerToggle.syncState();
}
Important thing, this is the way I hide the hamburger and show the back button. You have to put this code in the place you want to show back button. I also lock the Nav when showing back button.
if (!isShowBackButton) {
mActionBarDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
} else {
mActionBarDrawerToggle.setDrawerIndicatorEnabled(false);
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
//enable back button
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
