activity_navigation.xml
<?xml version="1.0" encoding="utf-8"?>
<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">
<ViewStub
android:id="#+id/content_frame"

in this class i am extending it:
public class Contact extends NavigationActivity implements View.OnClickListener {
private EditText mName,mNumber,mEmail,mMessage;
private FancyButton mSbmt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);

So, first of all you have to create a base abstract Activity with DrawerLayout:
public abstract class NavigationActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Title");
}
}
/**
* This method overrides the setContentView method to set DrawerLayout as a main layout.
*
* #param layoutResID Layout, which will be set in DrawerLayout as a content frame
*/
#Override
public void setContentView(final int layoutResID) {
super.setContentView(R.layout.navigation_drawer);
final ViewStub content = (ViewStub) findViewById(R.id.content_frame);
content.setLayoutResource(layoutResID);
content.inflate();
initDrawer();
}
/**
* This method initializes DrawerLayout and DrawerToggle
*/
private void initDrawer() {
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
null,
R.string.drawer_open,
R.string.drawer_close
) {
public void onDrawerClosed(final View view) {
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(final View drawerView) {
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(final Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(final Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(final MenuItem item) {
return mDrawerToggle.onOptionsItemSelected(item) || super.onOptionsItemSelected(item);
}
/**
* This method is called when user presses the back button. If the drawer is opened, it will be closed.
* Otherwise will be called the parent implementation.
*/
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
mDrawerLayout.closeDrawers();
} else {
super.onBackPressed();
}
}
}
Which uses a layout navigation_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<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">
<ViewStub
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="#+id/drawer_container"
android:layout_width="#dimen/drawer_width"
android:layout_height="match_parent"
android:orientation="vertical"
android:clickable="true"
android:background="#color/gray_dark"
android:layout_gravity="start">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is drawer"/>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
After that you can simply create some Activity and set its layout into ViewStub with id "content_frame". It will be done automatically in setContentView method in NavigationActivity
public class MainActivity extends NavigationActivity {
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
You also have to use a theme with ActionBar:
<resources
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#android:color/white</item>
<item name="android:background" tools:ignore="NewApi">#android:color/white</item>
</style>
</resources>
And set it in your manifest file:
<application
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
...

Android Sliding Drawer not Working

I have Implented Drawer with a SLider listner
But it does not work when swapping fingers Please Tell Me What i am doing wrong:
here is my frag class
public class frag extends android.support.v4.app.Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

drawerLayout = (DrawerLayout)getActivity().findViewById(R.id.drawer);
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
final ActionBar ab = getActivity().getActionBar();
ActionBarDrawerToggle abdl = new ActionBarDrawerToggle(
getActivity(),
drawerLayout,
R.string.action_settings ,
R.string.hello_world) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
ab.setTitle("closed");
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
ab.setTitle("opened");
}
};
drawerLayout.setDrawerListener(abdl);
}
public void close()
{
DrawerLayout drawerLayout = (DrawerLayout)getActivity().findViewById(R.id.drawer);
drawerLayout.closeDrawers();
}
}
here is the layout:

</RelativeLayout>

Your implementation for NavigationDrawer is completely wrong. You should call setup() from your parent activity's onCreate() function to initialize ActionBar and NavigationDrawer.
Sample code is given below:
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);
}
}
Android docs: http://developer.android.com/training/implementing-navigation/nav-drawer.html

When I implemented this, I used the following code with the help of this tutorial:
sliding menu tutorial
Drawer Adapter
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){
this.context = context;
this.navDrawerItems = navDrawerItems;
}
#Override
public int getCount() {
return navDrawerItems.size();
}
#Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
}
Main Activity
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// Home
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));
navMenuIcons.recycle();
// setting the nav drawer list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, //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);
if (savedInstanceState == null) {
// on first time display view for first nav item
displayView(0);
}
}
#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);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
#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);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
You then need to add the code for each fragment and the required resources respectively.
The xml layout file for the navigation slider would be similar to the one below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#drawable/list_selector">
<ImageView
android:id="#+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="#string/desc_list_item_icon"
android:src="#drawable/ic_home"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#id/icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="#color/list_item_title"
android:gravity="center_vertical"
android:paddingRight="40dp"/>
<TextView android:id="#+id/counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/counter_bg"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:textColor="#color/counter_text_color"/>
</RelativeLayout>

Changing navigation drawer items at runtime

The case is the following: I have two types of users, type1 and type2. Both have to login in order to go to the main activity which has a Navigation Drawer. The items in the navigation drawer depends on the type of the user. How can I change the items of the navigation drawer at runtime after I know the user type.

I found easier way to change navigation view ( work with both submenu and menu). You can re-inflate NavigationViewat runtime with 2 lines of code. In this example i re-inflate with new_navigation_drawer_items.xml when user successfully logged-in
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_in_navigation_drawer_items); //inflate new items.
When user log out just re-inflate again with logged_out_navigation_drawer_items.xml
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_out_navigation_drawer_items); //inflate new items.

LinearLayout Cannot Be Cast to ListView

I am working on making a navigation drawer using the in house code generated by Android Studio. I am trying to create my own custom layout for the navigation drawer, it seems the only difference between my custom layout and the one generated by Android Studio is that it uses tools:context = ".ACTIVITYNAME"
and that the ListView is the root layout.
Then I get the stack trace error, as the title suggests that a LinearLayout cannot be casted to a ListView.

I am confused. I was hoping it would be easier to alter the code. I just want to add an image header above the list view.

You have to define ID of each item in your layout and then get that item by its ID in your code.
For example your custom layout will look like this (look at android:id="#+id/listView")
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/Dark_Grey"
tools:context=".NavigationDrawerFragment">
<ImageView
android:layout_width="fill_parent"
android:layout_height="150dp"
android:id="#+id/imageView"
android:src="#drawable/bitsnbytes_logo_phrase"
android:padding="10dp"/>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#color/DARK_GREEN"
/>
</LinearLayout>
Then in your fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = (View) inflater.inflate(
R.layout.your_custom_navdrawer, container, false); // make sure it's your custom layout the one like above
ImageView imageView = (ImageView) view.findViewById(R.id.imageView); //id same as in your layout
mDrawerListView = (ListView) view.findViewById(R.id.listView); //id same as in your layout
}

Android support Toolbar + ActionBarDrawerToggle not changing to arrow

I'm struggling with the toolbar and drawer. I'm trying to make the burger switch to arrow when I'm adding a new fragment to the backstack but there is no way to do it.
Maybe I'm missing something but I could not find a way. Anyone had the same problem?
This is the declaration:
mDrawerToggle = new ActionBarDrawerToggle(
getActivityCompat(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
((BaseActivity) getActivityCompat()).getToolbar(),
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
)
This is the function I call when a fragment is added to the back stack
public void setToggleState(boolean isEnabled) {
if (mDrawerLayout == null)
return;
if (isEnabled) {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_UNLOCKED);
} else {
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}
mDrawerToggle.syncState();
}

I think all you have to do is to delete the third argument. Thus:
mDrawerToggle = new ActionBarDrawerToggle(
getActivityCompat(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
// ((BaseActivity) getActivityCompat()).getToolbar(), <== delete this argument
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
);
May it helps.

I had the same problem. My solution was this:
Make sure your activity implements onBackStackChangedListener. In your activities' onCreate I set the backstack listener and I set up the toolbar
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mFm = getFragmentManager();
mFm.addOnBackStackChangedListener(this);
// Setup toolbar
mToolbar = (Toolbar) findViewById(R.id.toolbar);
mToolbar.setVisibility(View.VISIBLE);
setSupportActionBar(mToolbar);
// Setup drawer toggle
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerlayout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.menu_open, R.string.menu_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle.syncState();
// Setup initial fragment
if (savedInstanceState == null) {
mCurrentFragment = DashboardFragment.newInstance();
mFm.beginTransaction().add(CONTAINER_ID, mCurrentFragment).commit();
}
}
Also remember to set:
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
Now the magic happens in onBackStackChanged(). Setting the setDrawerIndicatorEnabled to true for the top-most fragment and setDisplayHomeAsUpEnabled as false for that fragment. Inverse for the other ones. I also had to call syncState or else the hamburger wouldn't reappear:
#Override
public void onBackStackChanged() {
mDrawerToggle.setDrawerIndicatorEnabled(mFm.getBackStackEntryCount() == 0);
getSupportActionBar().setDisplayHomeAsUpEnabled(mFm.getBackStackEntryCount() > 0);
mDrawerToggle.syncState();
}

I have achieved it using following layout:
i have used ActionBarDrawerToggle v7
Drawer.xml

#hata's answer is spot-on for most cases.
But actually, you were not wrong using toolbar as argument to the ActionBarDrawerToggle(...) constructor.
Of course, there's no sense in doing that if you're using the stock Toolbar AppCompatActivity provides by using, say the stock Theme.AppCompat.Light root theme.
Even if you want a custom Toolbar in your layout, e.g. if you're implementing the Material Design's over-toolbar-under-statusbar Navigation Drawer pattern, you can still call setSupportActionBar(toolbar) and still not pass the toolbar to ActionBarDrawerToggle() letting the activity handle the navigation icon.
But if you really want to bind your ActionBarDrawerToggle to a Toolbar that's not activity's action bar, and maybe has different styling and a different icon or whatever -- there's still a way to go.
The thing is, when you don't pass the toolbar as the fourth parameter, the activity is supposed to provide the navigation icon (the arrow) -- and AppCompatActivity returns the value of homeAsUpIndicator attribute -- it's defined in either of the standard AppCompat themes.
However, when you explicitly pass the Toolbar, ActionBarDrawerToggle expects the toolbar instance to provide the navigation indicator drawable -- and it doesn't, because even if you apply the appropriate style to it like this:
<android.support.v7.widget.Toolbar
...
app:theme="?actionBarTheme"
style="#style/Widget.AppCompat.Toolbar">
for some reason (maybe it's even a bug), the Widget.AppCompat.Toolbar style doesn't have navigationIcon attribute, so Toolbar returns null when ActionBarDrawerToggle asks it for the nav icon. So, to cope with this, you simply derive from the style and add the attribute:
<android.support.v7.widget.Toolbar
...
app:theme="?actionBarTheme"
style="#style/MyWidget.Toolbar">
<!-- styles.xml -->
<style name="MyWidget.Toolbar" parent="Widget.AppCompat.Toolbar">
<item name="navigationIcon">?homeAsUpIndicator</item>
</style>
Now you can use the toolbar-aware constructor ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, 0, 0) and still have the navigation icon in place.

this line makes sure hamburger icon is changed to arrow on clicking. Make sure you have this written in your code.
mDrawerLayout.setDrawerListener(mDrawerToggle);
