I have a problem, I have different activity with different background color (white or blue), also the menu icon need to be white or blue (opposite to activity background), I can't find the correct way for change it after change activity, how can I do this?
U must do like this:
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.drawable.ic_drawer, //<-- This is the icon provided by Google itself
R.string.drawer_open,
R.string.drawer_close
)
This in setUp() method.
And dont forget to add these code:
#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);
}

I have problem with drawer indicator in toolbar.
The icon (hamburger) is visible only while moving (swiping) drawer view, and becomes invisible on stop.
Here is screenshot
http://imgur.com/EBGDq4z
And while moving it becomes visible
http://imgur.com/tEsAMLx
If stop move drawer view it becomes invisible again.
Here is my setup code
mToolbar.setVisibility(View.VISIBLE);
mToolbar.setTitle(getToolbarTitle());
setSupportActionBar(mToolbar);
if (hasDrawerToggle()) {
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerMainLayout,
R.string.drawer_open, R.string.drawer_close);
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerMainLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
if (hasDrawerToggle()) {
mDrawerToggle.syncState();
}
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (hasDrawerToggle()) {
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
Why are you using hasDrawerToggle() condition?
The problem may due to your condition, so try by removing condition from all places like onPostCreate,onCreate etc.
Hop it will work.
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close) { ... }
Okay, I double checked R.drawable.ic_drawer a few times. It is an icon with 3 bars, but my android display a left arrow. Anyone know what's wrong and how to fix it? Thanks in advance.
try to remove getActionBar().setDisplayHomeAsUpEnabled(true);
Call syncState() from your Activity's onPostCreate to synchronize the indicator with the state of the linked DrawerLayout.
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
Additionally onConfigurationChanged should be called on the ActionBarDrawerToggle, include this in your Activity:
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
In your NavigationDrawerfragment class go to setUp method and do something like this with actionbar to set actionBar.setHomeAsUpIndicator() to ic_drawer just like below. It will remove back button and replace with ic_drawer button
public void setUp(int fragmentId, DrawerLayout drawerLayout) {
mFragmentContainerView = getActivity().findViewById(fragmentId);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.ic_drawer);
}
I am trying to implement a navigation drawer,Everything working perfectly except the toggle button is not visible.
Here is my Code:
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.list, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility)
also added these functions
#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);
}
How can i make it visible?
we have to enable following method
getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true);
At least Gmail and Youtube Android apps use a side menu (navigation drawer?) that opens by swiping, or by clicking the app icon (home button):
Is the menu indicator / icon in the screenshot above a ready-made part of Android SDK? (Or a custom icon Google uses in their apps?) In any case, what's the easiest way to get your home button to look like that, i.e., like it opens a menu?
(targetSdkVersion 18; minSdkVersion 14)
Resolution
Finally got it working. What was missing for me was 1) the actual icon and 2) deferred call to syncState() on the ActionBarDrawerToggle.
To create similar implementation / look in your application you should use ActionBarDrawerToggle and set your custom icon as indicator next to ActionBar home button. For example :
import android.app.ActionBar;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
private void setUpDrawerToggle(){
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the navigation 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.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
) {
#Override
public void onDrawerClosed(View drawerView) {
invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
};
// Defer code dependent on restoration of previous instance state.
// NB: required for the drawer indicator to show up!
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
Where R.drawable.ic_drawer is actually the icon to use as indicator. You can find it in Android Asset Studio; see Navigation Drawer Indicator.
References
ActionBarDrawerToggle
Creating a Navigation Drawer
Android-Developer and HpTerm helped me in the right rirection, by
Pointing out this is indeed NavigationDrawer specific (which I was already using as in Google's example)
Telling where to find the ic_drawer.png icon (→ Android Asset Studio)
Now, unfortunately, creating ActionBarDrawerToggle like below seems not to be enough.
At least on my Nexus 7 (API 18) test device.
drawerToggle = new ActionBarDrawerToggle(this,
drawerLayout,
R.drawable.ic_navigation_drawer,
R.string.side_menu_open,
R.string.side_menu_closed) {
// ...
};
Partial solution (API level 18+)
I found one way to make the indicator show up though: setHomeAsUpIndicator(). The downside: that method was added in API level 18.
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
getActionBar().setDisplayHomeAsUpEnabled(true); // also required
if (Build.VERSION.SDK_INT >= 18) {
getActionBar().setHomeAsUpIndicator(
getResources().getDrawable(R.drawable.ic_navigation_drawer));
}
}
So now the question remains: how to make this work (in my case) for API levels 14 through 17?
I verified on a 4.1.2 (API 16) device that the ic_drawer icon does not show up. With setDisplayHomeAsUpEnabled(true) I get the normal "home" icon (small arrow pointing left) and without it, the space left to my app icon remains blank.
Final solution
Got it working using the edited version of Android-Developer's answer.
Quite curiously, what was missing from my ActionBarDrawerToggle initialisation code was this:
// Defer code dependent on restoration of previous instance state.
drawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
With that included, calling setHomeAsUpIndicator() is not needed.
The keyword here is NavigationDrawer; there's a full working code example on the Android developer site.
READ THE END OF THE LINK GIVEN : Open and Close with the App Icon
The following code is copied from there
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) {
getActionBar().setTitle(mTitle);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View 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);
}
...
}
Some files are available as download and the small 3 lines with the animation effect is fully exemplified.
You have to copy thoses files in the corresponding drawable folder. Depending on the theme you use, dark or light you have a different set of icons.
In my case I simply copied the drawer_shadow.9.png and ic_drawer.png in the drawable folder and followed the example and everything works just fine.
The icons are available in the link I provided, but they are NOT in the "Action Bar Icon Pack", they are in the sample app in the corresponding res/drawable folders.
I have an activity with a DrawerLayout. I can open the drawer two different ways...by swiping from the left area of the screen towards the right and by clicking the app title. I DO NOT have an app icon displayed, only a title. I've implemented this exactly as recommended by Google here: Creating a Navigation Drawer: Open and Close with the App Icon
Everything is functional as far as opening and closing the drawer itself. However, it does not display the standard DrawerLayout icon that is suppose to be used. Instead I get the regular up caret (looks like a less than sign).
As soon as I add the app icon back to the ActionBar it begins to work as expected. The Drawer layout icon displays and animates when the drawer is opened or closed. I've tried removing the app icon both in my styles XML file and programmatically.
Is there a way to get the DrawerLayout icon working WITHOUT the app icon???
UPDATE: I've found a work around, but it's a hack more so than a solution. I simply created a 1x1 pixel transparent PNG (blank.png) and set it as my app icon in my styles.xml file. Below is all relative code:
styles.xml
<style name="MyCustomTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyCustomActionBar</item>
<item name="android:icon">#drawable/blank</item>
</style>
<style name="MyCustomActionBar" parent="#android:style/Widget.Holo.ActionBar">
<item name="android:displayOptions">showHome|showTitle|homeAsUp</item>
</style>
MainActivity -> onCreate()
this.navDrawerToggle = new ActionBarDrawerToggle
(
this,
this.navDrawerLayout,
R.drawable.icon_nav_drawer,
R.string.nav_drawer_open,
R.string.nav_drawer_closed
)
{
public void onDrawerClosed(View view) {}
public void onDrawerOpened(View drawerView) {}
};
MainActivity -> onPostCreate()
super.onPostCreate(savedInstanceState);
this.navDrawerToggle.syncState();
MainActivity -> onResume()
this.navDrawer.setOnItemClickListener(new DrawerItemClickListener());
this.navDrawerLayout.setDrawerListener(this.navDrawerToggle);
MainActivity -> onPause()
this.navDrawer.setOnItemClickListener(null);
this.navDrawerLayout.setDrawerListener(null);
MainActivity -> onConfigurationChanged(Configuration newConfig)
super.onConfigurationChanged(newConfig);
navDrawerToggle.onConfigurationChanged(newConfig);
MainActivity -> onOptionsItemSelected(MenuItem item)
if (this.navDrawerToggle.onOptionsItemSelected(item)) {return true;}
else
{
// A bunch of item click handling happens here...
return true;
}
I was curious about this so I tried it with the sample for the DrawerLayout and it worked fine. Also, it seems like you have to use your own drawer icon drawable, it's recommended anyways. You can download the default assets from this site Creating a Navigation Drawer and put them in their respective drawable resource folder.
Here's what worked for me:
ActionBar actionBar = getActionBar();
// Let's get rid of the app icon here
actionBar.setIcon(null);
actionBar.setTitle("App Name");
// Setting these 3 options allows us to show the title as well as a "Home" elements
// "Home" elements include the Up and/or Drawer icon. The DISPLAY_HOME_AS_UP will enable
// and show the Drawer icon, we'll be "replacing" the "up" button with the drawer icon below
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE
| ActionBar.DISPLAY_SHOW_HOME
| ActionBar.DISPLAY_HOME_AS_UP);
// Get a reference of the DrawerLayout
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.setDrawerListener(drawerToggle);
// Setting ActionBarDrawerToggle will allow you to set the drawables for the drawer
// (this will also give you the nice/smooth animation) as well as allow you to do some
// other things depending on the events: onDrawerClosed & onDrawerOpened.
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* 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_closed /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
actionBar.setTitle("Closed...");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
actionBar.setTitle("Open...");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
// Set a listener to be notified of drawer events.
drawerLayout.setDrawerListener(drawerToggle);
UPDATE: It seems like the android:displayOptions on the ActionBar style are not being accounted for. Use actionBar.setDisplayOptions(int options) instead.
getActionBar().setIcon(android.R.color.transparent);
This worked for me..... ;)
After setting the drawer toggle you need to call the following method:
mDrawerToggle.syncState();
so your code would look like this:
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) {
actionBar.setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
actionBar.setTitle("Preview Mode");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerToggle.syncState();
mDrawerLayout.setDrawerListener(mDrawerToggle);
