Why my Drawer menu looks black? - android

I have created a Drawer Menu Example, Following is my source code,
public class DrawerActivity extends Activity
{
private String [] menuOptions = new String[] { "Option1", "Option2","Option3" };
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private ArrayAdapter<String> adapter;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
adapter = new ArrayAdapter<String> ( this, android.R.layout.simple_list_item_1, menuOptions );
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
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, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
)
{
public void onDrawerClosed(View view)
{
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView)
{
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
private class DrawerItemClickListener implements ListView.OnItemClickListener
{
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3)
{
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerLayout.closeDrawer(mDrawerList);
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this.
if (mDrawerToggle.onOptionsItemSelected(item))
{
return true;
}
else return false;
}
}
This is the code of my AndroidManifest.xml file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.drawerdemo"
android:versionCode="1"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
The code is working fine but my Drawer menu appears as black, see the image

Change background color of your menu layout

You can try changing the theme for your Activity.
Under your res/values folder, go to the styles.xml file and change your theme.
This can be done like so:

How to add one section separator for Navigation Drawer in Android?

I have a navigation drawer like this image. I want to add a section separator (like the line separating Neptune). It seems simple but I can't find anything on the web that was useful for my case.
Here is my MainActivity:
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.planets_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// 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.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 */

I want this to be simple but I can't find anything good on the web. Is there a way that I can isolate Neptune and create a section for it? Does anyone have any suggestions? Thanks.
Make sure you define each group with a unique ID, separator won't appear without the ID.
For example, this is my drawer_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group
android:id="#+id/menu_top"
android:checkableBehavior="single">
<item
android:checked="true"
android:id="#+id/drawer_item_timeline"
android:icon="#drawable/ic_timer_grey600_24dp"
android:title="#string/drawer_timeline"/>
<item
android:id="#+id/drawer_item_reports"
android:icon="#drawable/ic_timetable_grey600_24dp"
android:title="#string/drawer_reports"/>
</group>
<group
android:id="#+id/menu_bottom"
android:checkableBehavior="none">
<item
android:id="#+id/drawer_item_settings"
android:icon="#drawable/ic_settings_black_24dp"
android:title="#string/drawer_settings" >
</item>
</group>
</menu>
Gabriel adds below in the comments that if the group doesn't have an id, the separator will not appear.
To separate menu items by a divider line, only group items with a unique id like following example:
activity_main_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<item
android:id="#+id/nav_apps_and_games"
android:icon="#drawable/ic_apps_black_24dp"
android:title="#string/my_apps_and_games" />
<item
android:id="#+id/nav_bookmarked_apps"
android:icon="#drawable/ic_add_bookmark_black_24dp"
android:title="#string/bookmarked_apps" />
<item
android:id="#+id/nav_manage_downloads"
android:icon="#drawable/ic_downloading_file_black_24dp"
android:title="#string/manage_downloads" />
<!-- SET A UNIQUE ID TO THE BELOW GROUP -->
<group android:id="#+id/group1">
<item
android:id="#+id/nav_settings"
android:icon="#drawable/ic_settings_black_24dp"
android:title="#string/settings" />
<item
android:id="#+id/nav_sign_up"
android:icon="#drawable/ic_card_membership_black_24dp"
android:title="#string/sign_up_login" />
</group>
</menu>
Visual Result:
My hacky method is similar to Mostrapotski's.
In my Layout for my custom adapter, I'm adding a horizontal separator at the beginning of each item and setting it's visibility to gone.
For the elements that mark the beginning of a new group, I set their visibility to visible so that the separator shows up on top of it.
You have two choices
Your items can be separated (a list at the top, and classic views at the bottom).
Then instead of the listview in your main layout (android:id="#+id/left_drawer") you can have a rather complex LinearLayout including those 3 items (list, separator, and bottom views)
Your items must be exactly as in your example, then you need the separator in the list, you can use some logic in your adapter to draw a view on top of the list item where you need the separator. (meaning your list item won't be a single textview anymore, but a LinearLayout with a gone separator (and visible sometimes, according to your adapter's logic).
To help you with some sample code, can you please post all the items you need in your menu ? We need to know exactly what will be static and what will be scrollable.
Edit: If you want that working with the exemple, get rid of the line
mDrawerList.setAdapter(new ArrayAdapter<String>(this, ...)
You need to supply a home made adapter like this:
https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView
As i said in 2, in your adapter, you will have logic, and thus you can say in the getView() method
if(myPlanet.isNeptune())
holder.mSepatator.setVisibility(View.VISIBLE);
else
holder.mSepatator.setVisibility(View.GONE);
Add group in Menu file to add divider
enter image description here
<group android:checkableBehavior="none">
<item android:title="______________________________________________________________"
android:iconTint="#color/colorWhite"
android:enabled="false">
</item>
</group>

Android 5 Hamburger doen't open the drawer

I'm trying to make a simple navigation drawer, matching the material guidelines. I'm following along the official training. Everything is running well, only a tap on the hamburger icon won't open the drawer. I can open the drawer with a swipe from the side, only the hamburger isn't working. I already looked up some other questions like this one, but nothing helped. What did I miss?
Here is my code:
Activity.java:
public class stream extends ActionBarActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private String[] mDrawerTitles;
private ListView mDrawerList;
private Toolbar mToolbar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stream);
// Init the Support-toolbar
mToolbar = (Toolbar) findViewById(R.id.toolbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onBackPressed() {
if(mDrawerLayout.isDrawerOpen(Gravity.START|Gravity.LEFT)){
mDrawerLayout.closeDrawers();
return;
}
super.onBackPressed();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggle
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
Layout.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

You are not using the DrawerLayout as the root layout of the activity. You are almost there but you see how you use the RelativeLayout as the root (or at least that is what I infer from the posted xml - the RelativeLayout does not look like it has a closing tag so maybe you just missed it)?
The NavigationDrawer opens on the tap of the "hamburger" (or icon) only when it is the root so that Android knows that the DrawerLayout is encompassing everything. My guess is the toolbar you are including is interfering with the layout.

Navigation Drawer is not opening when sliding from left

As the page on Android Developers says
The user can bring the navigation drawer onto the screen by swiping from the left edge of the screen or by touching the application icon on the action bar.
But strangely the navigation drawer on my activity does not respond to sliding action. It toggles only on touching the icon on the action bar. Below is my implementation of the navigation drawer
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
// Set up the drawer.
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
drawerLayout);
Is there any possible explanation for this? What I doubt is my activity by default has the layout of one of its fragments. So is that the reason?
Edit: The layout file of my activity
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainPage">
<!-- The main ocntent view -->
<FrameLayout android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- The navigation drawer-->
<fragment android:id="#+id/navigation_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent"
android:name="com.example.android.handsfree.NavigationDrawerFragment"
tools:layout="#layout/fragment_navigation_drawer" />
Your ´NavigationDrawerFragment´ already creates a drawer Toggle for you inside its `setUp´ method.
You should not create a new one inside your ´MainPage´ Activity.
Notes:
You can use the android.support.v7.app.ActionBarDrawerToggle instead of the v4 one inside the NavigationDrawerFragment.
Update:
The problem seems solved now. There were 2 Issues:
The OP created a second drawer toggle in it's MainPage - Activity but there was already one created inside the NavigationDrawerFragment's setUp method, which gets called by the MainPage in order to set up the drawer. (This is basicly outsourc[ecoding]ing some of the drawer stuff to the drawer fragment.)
The OP locked the drawer inside onCreateOptionsMenu by calling a method which sets the DrawerLockMode to LOCK_MODE_LOCKED_CLOSED. He never reverted this change.
You should use:
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
<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"
android:background="#color/white" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="#+id/listview_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/drawer"
android:choiceMode="singleChoice" />
on your activity
drawlayout = (DrawerLayout) findViewById(R.id.drawer_layout);
listData = (ListView) findViewById(R.id.listview_drawer);
drawlayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
Add these fields in your activity class:
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
Then, inside your activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true)
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
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) {
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// toggle nav drawer on selecting action bar app icon/title
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#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);
}
ic_drawer is a .png image which located in drawable resources. You can search this image on Google.
API level to be used is 11+.
Hope it helps for you.
1- replace the tag by :
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainPage">
<!-- The main ocntent view -->
<FrameLayout android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- The navigation drawer-->
<ListView android:id="#+id/navigation_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent" />
</android.support.v4.widget.DrawerLayout>
2- use this code in the onCreate function u can use the v4 ActionBarDrawerToggle or the v7 her i use the v4:
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,R.drawable.ic_drawer,
R.string.app_name,R.string.app_name) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);

Navigation drawer: text is hidden below actionbar?

I added navigation drawer to my application. Everything works fine, but now I am trying to add a simple textView to menu, and am not succeeding. The problem is the fact that text is hidden underneath actionBar itself. Even 50dp margin from top isn't enough.
Do you have any tips on how to fix this issue?
My main activity:
<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">
<!-- The main content view -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/container"
android:fitsSystemWindows="true"
android:clipToPadding="false"/>
<!-- The navigation drawer -->
<FrameLayout
android:id="#+id/left_drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#color/dark_brown">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textSize="40dp"
android:textColor="#ffffff"
android:id="#+id/textView"
android:layout_marginTop="50dp"
android:layout_marginLeft="20dp"
android:gravity="center_vertical"/>
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
And my main activities class:
public class MainActivity extends ActionBarActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private DatabaseHandler database;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

SystemBarTintManager tintManager = new SystemBarTintManager(this);
tintManager.setStatusBarTintEnabled(true);
tintManager.setStatusBarTintResource(R.color.action_bar_bg);
}

You want to assign fitsSystemWindows and clipToPadding to the Navigation Drawer fragment (most probably the ListView)
Something like this -
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#cccc"
android:fitsSystemWindows="true"
android:clipToPadding="false"
/>
But in your case, you are using the FrameLayout on the activity_main itself to populate the Drawer contents. So you have to apply these two properties to the FrameLayout
<FrameLayout
android:id="#+id/left_drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:clipToPadding="false"
android:background="#color/dark_brown">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textSize="40dp"
android:textColor="#ffffff"
android:id="#+id/textView"
android:gravity="center_vertical"/>
</FrameLayout>
Also, notice, you don't need following to your TextView anymore.
android:layout_marginTop="50dp"
android:layout_marginLeft="20dp"

ActionBarDrawerToggle is not setting Drawer Indicator

I am trying to add the navigation drawer in my app.. Everything is working fine But now I still got the arrow icon although I replaced it with the ic_drawer from Android? Here's my code:
private ActionBarDrawerToggle mDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ExpandableListView mDrawerList = (ExpandableListView) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
mDrawerList.setAdapter(new DrawerListAdapter(this));
mDrawerList.setOnChildClickListener(new DrawerItemClickListener());
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_launcher, R.string.drawer_open,
R.string.drawer_close);
Log.d("Mudit",
"mDrawerToggle" + mDrawerToggle.isDrawerIndicatorEnabled()); // returns true
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayShowHomeEnabled(false);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
XML:
<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" >
<ScrollView
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
<ExpandableListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#ffffff"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
I have looking at various code samples online but all of them are doing same thing. I dont know why it is not working for me.
Please help.
You'll have to use
getActionBar().setDisplayShowHomeEnabled(true);
instead of
getActionBar().setDisplayShowHomeEnabled(false);
Cheers,
Felix
EDIT: Here's how to hide the Icon via XML:
add this to your styles.xml: (Replace android:Widget.Holo.Light.ActionBar.Solid with android:Widget.Holo.ActionBar.Solid if you are using the dark action bar)
<style name="ActionBarStyle" parent="android:Widget.Holo.Light.ActionBar.Solid">
<item name="android:icon">#android:color/transparent</item>
</style>
and then add this to your Theme you have defined in AndroidManifest.xml (Standard is the AppBaseTheme in /res/values-v11/styles.xml - AppBaseTheme:
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
Hope this helps!
try this code
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
actbardrawertoggle.syncState();
}
This worked for me when I wanted to get the menu icon back from the back arrow
private void updateNavigationIcon() {
if (getSupportFragmentManager().getBackStackEntryCount() == 0
&& getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
toggle.syncState();
}
}
Just add the following line inside showGlobalContextActionBar() method (NavigationDrawerFragment.java class)
actionBar.setHomeAsUpIndicator(R.drawable.ic_action_menu);
Code snippet:
private void showGlobalContextActionBar() {
ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.ic_action_menu);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setTitle(R.string.app_name);
}
