Android navigationView when is visible on screen listener

Is there a listener for navigationView if it is actived (Is visible on screen)?
I tried setonsystemuivisibility but not works.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
I need listener to be called when it's on screen and when it's gone.
thanks.

Add a DrawerListener:
mDrawerLayout = findViewById(R.id.drawer_layout);
mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener()
{
// other overridden methods not shown
#Override
public void onDrawerOpened(View drawerView)
{
// drawer opened
// todo: announce for accessibility
}
});

Hope This will help you
DrawerLayout mDrawerLayout;
public static ActionBarDrawerToggle mDrawerToggle;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(FragmentHomeActivity.this, mDrawerLayout, toolbar, R.string.app_name, R.string.app_name){
public void onDrawerClosed(View view) {
//calling onDrawerClosed, when View gone invisible
}
public void onDrawerOpened(View drawerView) {
// calling onDrawerOpened, when View visible
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
If you are using Toolbar, then
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

Android - Navigation Drawer change action bar icon

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);
}

How to set drawer toggle icon (`hamburger`) for the ActionBarDrawerToggle v7 without toolbars

I'm using action bar from android.support.v7.app.ActionBarActivity so my activity is declared like this:
public class MyActivity extends ActionBarActivity {
I'm reading the tutorial which shows how to add Drawer:
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close);
This is for the import android.support.v4.app.ActionBarDrawerToggle. Now I've decided to use v7 since v4 is deprecated, but the constructor for the v7 doesn't accept icon for the drawer. I've googled and found that the solution is to use the constructor flavor that accepts toolbar:
ActionBarDrawerToggle(this, drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)
but I don't use toolbars. So I don't understand how I can set icon with v7 without toolbars. Should I switch to using Toolbars?

Hey you get the solution here..
private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_drawer);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
toolbar,
R.string.drawer_open,
R.string.drawer_close) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
This one is also a good approach, personally i use this one.
public class MyActionBarDrawerToggle extends android.support.v7.app.ActionBarDrawerToggle {
public MyActionBarDrawerToggle(Activity activity, final DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes) {
super(activity, drawerLayout, toolbar, openDrawerContentDescRes, closeDrawerContentDescRes);
setHomeAsUpIndicator(R.drawable.drawer_toggle);
setDrawerIndicatorEnabled(false);
setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
drawerLayout.openDrawer(Gravity.LEFT);
}
});
}
}
Thank you.

ActionToggle image not showing

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!

How to replace the hamburger icon used for ActionBarToggle on Android Toolbar with a custom drawable?

I have implemented a basic ActionBarDrawerToggle using the new Toolbar in Android 5.0.
However, I am unable to figure out how to change the default hamburger icon that is supplied.
From the android documentation it says that "the given Activity will be linked to the specified DrawerLayout and the Toolbar's navigation icon will be set to a custom drawable... This drawable shows a Hamburger icon when drawer is closed and an arrow when drawer is open. It animates between these two states as the drawer opens."
I currently have this all working correctly with the following code, however I want to replace the default supplied hamburger with my own drawable.
Here is my current code:
MainActivity.java
#InjectView(R.id.main_activity_toolbar)
Toolbar mToolbar;
#InjectView(R.id.main_activity_drawer_layout)
DrawerLayout mDrawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.main_activity);
super.onCreate(savedInstanceState);
setSupportActionBar(mToolbar);
mToolbar.setNavigationIcon(R.drawable.navigation);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
This line:
mToolbar.setNavigationIcon(R.drawable.navigation);
doesn't seem to work.
Is this possible to do? Thanks!
ActionBarToggle Documentation - https://developer.android.com/reference/android/support/v7/app/ActionBarDrawerToggle.html

You can use the toolbar as Stand Alone mode, that means you should not use your toolbar as part of your ActionBarDrawerToggle constructor, you can achieve that using the below code:
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, null,
R.drawable.appbar, R.drawable.appbar)
(Note how the toolbar instance is not being sent to the ActionBarDrawerToggle constructor)
Also, you should inflate your menu manually
mToolbar = (Toolbar) findViewById(R.id.nav_toolbar);
mToolbar.inflateMenu(R.menu.base);
And remove the setSupportActionBar(mToolbar); line of code.
Of course, you will have to handle the navigation click by yourself:
mToolbar.setOnMenuItemClickListener(new OnMenuItemClickListener() ...
Then, you can open your drawer like this:
drawerButton = (BadgeDrawerButton) findViewById(R.id.badge_drawer_button);
drawerButton.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
mDrawerLayout.openDrawer(Gravity.LEFT);
}
});
Hope this may help.

These two lines of code work for me:
mDrawerToggle.setDrawerIndicatorEnabled(false); //disable "hamburger to arrow" drawable
mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer); //set your own
And then call this:
mDrawerToggle.syncState();

The default menu drawable for the ActionBarDrawerToggle is DrawerArrowDrawable.
You can subclass this to add custom functionality, like badges, like so:
public class BadgedDrawerArrowDrawable extends DrawerArrowDrawable {
/**
* #param context used to get the configuration for the drawable from
*/
public BadgedDrawerArrowDrawable(Context context) {
super(context);
setColor(context.getResources().getColor(R.color.colorAccent));
}
#Override
public void draw(Canvas canvas) {
super.draw(canvas);
Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);
paint.setColor(Color.RED);
paint.setTextSize(60);
canvas.drawText("!", canvas.getWidth() - 60, 25, paint);
}
}
Usage:
actionBarDrawerToggle.setDrawerArrowDrawable(new BadgedDrawerArrowDrawable(activity));

My solution is by subclassing ActionBarDrawerToggle.
public class MyActionBarDrawerToggle extends android.support.v7.app.ActionBarDrawerToggle {
public MyActionBarDrawerToggle(Activity activity, final DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes) {
super(activity, drawerLayout, toolbar, openDrawerContentDescRes, closeDrawerContentDescRes);
setHomeAsUpIndicator(R.drawable.drawer_toggle);
setDrawerIndicatorEnabled(false);
setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
drawerLayout.openDrawer(Gravity.LEFT);
}
});
}
}

the thing that worked for me is that i just needed to call toolbar.setNavigationIcon(R.drawable.ic_camera_alt_24dp);
at the end of onCreate, or at least after mDrawerToggle = new ActionBarDrawerToggle...

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
final ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_action_name);

as of Jan 2018, this is a working solution (at least for me):
//setSupportActionBar(toolbar)
val toggle = ActionBarDrawerToggle(this, drawer_layout, null, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
toolbar.inflateMenu(R.menu.menu_main)
toolbar.setNavigationIcon(R.drawable.ic_menu)
toolbar.setNavigationOnClickListener {
drawer_layout.openDrawer(Gravity.START)
}
toolbar.setOnMenuItemClickListener {
true
}
drawer_layout.addDrawerListener(toggle)
toggle.syncState()
nav_view.setNavigationItemSelectedListener(this)
things to care:
setSupportActionBar should be commented out
ActionBarDrawerToggle is not taking a reference to toolbar
We should inflate menu ourself, and handle onClicks. onCreateOptionsMenu and onOptionsItemSelected will not be functioning.
Don't forget to call toggle.syncState()

As for v7 support library - you can create your own representation of DrawerArrowDrawable.
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
public void onDrawerClosed(View view) {
supportInvalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
supportInvalidateOptionsMenu();
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
DrawerArrowDrawable drawerArrowDrawable = new DrawerArrowDrawable(this);
drawerArrowDrawable.setAlpha(1);
drawerArrowDrawable.setSpinEnabled(false);
drawerArrowDrawable.setDirection(DrawerArrowDrawable.ARROW_DIRECTION_LEFT);
drawerArrowDrawable.setColor(Color.BLACK);
mDrawerToggle.setDrawerArrowDrawable(drawerArrowDrawable);

Here's how I was able to finally get mine to work.
private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_drawer);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
toolbar,
R.string.drawer_open,
R.string.drawer_close) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
It turned out to be the
mDrawerToggle.syncState();
That finally got everything to work.

I think it is recommended to put the call to syncState() in the onPostCreate(...) lifecycle method.
#Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
