I am working in library format and I have design different headers.
But the library should have some interfaces. So from main activity in the project, you call the library and send the array of icons that will be loaded dynamically in the toolbar of the header.
MainActivity.java code is:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
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);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView =
(NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
There is an option to load the array dynamically in the toolbar
You can set the icon of the items of your menu by calling the method setIcon(int) of the desired item. In this example there is only one item that changes its icon if the user liked or not a movie. "liked" is a boolean that is changed in other part of the code and then invalidateOptionsMenu() is called to recreate the menu (onCreateOptionsMenu is called after invalidation).
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.your_xml_menu, menu);
MenuItem item = menu.getItem(0);
if (liked) {
item.setIcon(R.drawable.liked);
} else {
item.setIcon(R.drawable.not_liked);
}
return super.onCreateOptionsMenu(menu);
}
You can also change the visibility of an item calling item.setVisible(false); or even inflate different xml for different configurations.
Try this one will help you:
You just crate menu item in your Activity then you can implement multiple icons.
Create a menu folder in your existing resource res folder.
Create a main.xml file in menu folder.
main.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_item_one"
android:title="Camera"
android:icon="#drawable/ic_menu_camera"
app:showAsAction="always" />
<item
android:id="#+id/action_item_two"
android:title="Send"
android:icon="#drawable/ic_menu_send"
app:showAsAction="always" />
</menu>
In your activity, override onCreateOptionsMenu() and onOptionsItemSelected() to work with option menus.
ActionBarActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_camera) {
// Do something
return true;
}
if (id == R.id.action_send) {
// Do something
return true;
}
return super.onOptionsItemSelected(item);
}

I want to use a standalone toolbar and for that I defined a android.support.v7.widget.Toolbar in my layout.
I want to add an item in the menu and using inflateMenu the toolbar seems to work fine but the inflateMenu was added in API-21.
How can I add a menu for earlier SDKs?
If you wanna add/show menu buttons, why don't you use
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.your_menu_layout, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_button1) {
return true;
}
return super.onOptionsItemSelected(item);
}
To use the SupportToolbar like the default one, you need to tell your Activity to use it as a normal Toolbar by using
Toolbar myToolbar = findViewById(R.id.toolbar);
setSupportActionBar(myToolbar);
After that you can use the Toolbar like a default one with Framework functionalities like onCreateOptionMenu or onOptionsItemSelected.
I have an action bar with a drawer on the left. I want to add another menu on the right side of the action bar. It can be three dots or a button or anything else. Is there any way to do this?
Thanks :)
For achieving 3 dots menu in your actionBar, in your activity (which extends AppCompatActivity or ActionBarActivity), you override the creation of options menu like below
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.your_menu, menu);
return true;
}
Where this R.menu.your_menuis a resource item present in your res/menu folder. One sample menu resource file content
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="your_package.your_activity">
<item
android:id="#+id/action_edit"
android:orderInCategory="100"
android:title="#string/action_edit"
app:showAsAction="collapseActionView"/>
<item
android:id="#+id/action_settings"
android:orderInCategory="101"
android:title="#string/action_settings"
app:showAsAction="collapseActionView"/>
</menu>
This will show a menu with both the options collapsed by default. To listen for clicks on these menu items, you override onOptionsItemSelected and perform the necessary action
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
//Do something
...
return true;
case R.id.action_edit:
//Do something else
...
return true;
}
return super.onOptionsItemSelected(item);
}
You can create a layout for your ActionBar and then use something like the following in your activity:
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.custom_action_bar);
And in your R.layout.custom_action_bar create the buttons you need.
I have implemented Hamburger bar with App toolbar and both of them are working fine. Following is the snapshot of toolbar and hamburgerbar:
Hamburger bar
I can open this bar by sliding it but I also want to make it open by clicking on drawable icon (right top corner icon). How can i do that?
MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
drawerFragment = (FragmentDrawer)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), toolbar);
drawerFragment.setDrawerListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
return super.onOptionsItemSelected(item);
}
I don't think so that I need to do some changes in layout files. What do I have to add in MainActivity file to make it possible?
I am newbie in Android code. Any help will be appreciable.
Using the Toolbar component should be fairly easy to achieve this by using a similar code to this:
Toolbar toolbar = (Toolbar) findViewById(R.id.home_toolbar);
toolbar.inflateMenu(R.menu.menu_home);
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if (item.getItemId() == R.id.action_settings) {
mDrawerLayout.openDrawer(Gravity.RIGHT); // where mDrawerLayout is your android.support.v4.widget.DrawerLayout in your activity's xml layout.
}
return false;
}
});
EDIT:
The key component here is the menu_home.xml file which goes to your res/menu folder. You can add your desired menu item there, customize it's icon and even more, add as many items as you'd like to have on the right side of the toolbar(Obviously handle the openDrawer() method on whichever menu item you need - the recommended one is the rightmost though).
Use the openDrawer() method.
private DrawerLayout mDrawerLayout;
...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
...
mDrawerLayout.openDrawer(Gravity.END); // or whatever gravity the of the drawer you want to open
Use Activity's onOptionsItemSelected(MenuItem menuItem) method:
First of all, keep the reference to your DrawerLayout in a class field:
DrawerLayout drawerLayout;
Somewhere in onCreate put this:
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout)
And implement the method:
#Override
public boolean onOptionsItemSelected(MenuItem menuItem) {
// if you want the default back/home hamburger menu item just put android.R.id.home instead
if (menuItem.getItemId() == R.drawable.icon_navigation) {
drawerLayout.openDrawer(GravityCompat.END);
}
return super.onOptionsItemSelected(menuItem);
}
This is the beahviour of my App (only 1 is right, of course):
Of course I want only one item at the moment checked.
I divided the items in two groups (to add the divider, see my previous question: How add horizontal separator in navdrawer? )
This is the nav_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single"
android:id="#+id/group1" >
<item
android:id="#+id/home"
android:checked="false"
android:icon="#drawable/ic_home_black_24dp"
android:title="#string/list_home" />
<item
android:id="#+id/list_event"
android:checked="false"
android:icon="#drawable/ic_list_black_24dp"
android:title="#string/list_event" />
</group>
<group
android:checkableBehavior="single"
android:id="#+id/group2" >
<item
android:id="#+id/settings"
android:checked="false"
android:icon="#drawable/ic_settings_black_24dp"
android:title="#string/settings" />
</group>
</menu>

Thank you very much
This could help you: Try to removing the tag android:checkableBehavior="single" from xml and set android:checkable = “true” for each item individually, then declare a MenuItem object in the activity and in onNavigationItemSelected event if previously declared MenuItem object is not null then set checked value as false for it and then save current selected menuItem received as parameter to earlier declared MenuItem object.
This will set checked selection on even subitems.
if (prevMenuItem != null) {
prevMenuItem.setChecked(false);
}
menuItem.setChecked(true);
mDrawerLayout.closeDrawers();
prevMenuItem = menuItem;
return true;
I found this solutions here
If you are using groups and android:checkableBehavior="single", then all you need to do is set the single item as the checked item in the navigation view (not simply the item as checked with item.setChecked(true)):
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
//item.setChecked(true); //Won't work, will leave previous item checked too.
navigationView.setCheckedItem(id); //this will check single item
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Now, whether you select or emulate select for an item, it will check only one item at a time.
Put both group inside single group an set
android:checkableBehavior="single"
Create a parent group
You would have to implement a custom adapter, custom/model, custom function to uncheck other items on click.
I suggest you to use this library. Its a material navigation drawer implementation, it already has all this logic implemented. If you dont want to go with a lib, them you should check how its done on this library code and adapt to your needs.
I am trying to implement DrawerLayout. The drawer layout is working fine. But the icon displayed in Top Left corner is android.R.id.home. However I have mentioned my custom icon in ActionBarDrawerToggle as follows:
// Getting reference to the DrawerLayout
drawerLayout = (android.support.v4.widget.DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.drawer_list);
// Getting reference to the ActionBarDrawerToggle
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
**R.drawable.icon_top_menu**, R.string.drawer_open,
R.string.drawer_close) {
/** Called when drawer is closed */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
}
/** Called when a drawer is opened */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
// Setting DrawerToggle on DrawerLayout
drawerLayout.setDrawerListener(drawerToggle);
getActionBar().setIcon(R.drawable.icon_top_menu);
// enabling action bar app icon and behaving it as toggle button
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
What's the problem?
You should check your onoptionsItem selected, should missing there...............
as shown below:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
in place of '.action_settings' try 'icon_top_menu' your icon.......
you should use visibility true/false for the icon menu in each activity where you want to show your icon...and please describe your question properly what you want to do.
To
user1182217
okay i got your problem some what, hope this will help you.
as for icon id you are using "android.R.id.home" which is 'android id' by default,
in place of that use your icon id as R.id.home/ R.id.your_icon_id hope the only error as
per your problem description..........
