Is it possible to call a function of Activity from drawer?
Let say: Main Activity is opened. There is a function displayImage() in it. I want to call it from drawer.
**Please go through the bellow code snippet**
drawer.xml file
<?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">
<group android:checkableBehavior="single">
<item
android:id="#+id/u_name"
android:icon="#drawable/lead_leader"
android:title="User name" />
<item
android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout" />
</group>
</menu>
**after that add bellow code in your Mainactivity.java file**
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.lead_profile, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.logout) {
//call your other method according navigation drawer item with other id in a different if block.
///call your function here
}
return super.onOptionsItemSelected(item);
}

I want to add 2 or 3 icons on action Bar in android app. I already took the empty activity and added the toolbar. I also set the Icon at left side. Now i want to add another two icons on it. But there is no Menu folder in my project directory structure. So any one tell me how i can do this all with proper guidelines?
My code is here :
My activity file
public class ActionBarActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_action_bar);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setIcon(R.drawable.left_nav);
getSupportActionBar().setTitle("");
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
}
my .xml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:fitsSystemWindows="true"
tools:context="firstapp.vaibhav.com.firstapp.ActionBarActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
Screen shot of my project directory structure
1. Create a menu folder in your existing resource res folder. (Ex. .../res/menu)
2. Create a main.xml file in menu folder. (Ex. .../res/menu/main.xml)
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>
3. 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);
}
OUTPUT
Hope this will help~
create menu.xml with item like this
<?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_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />-->
<item
android:id="#+id/action_refresh"
android:orderInCategory="100"
app:showAsAction="always"
android:icon="#drawable/ic_action_autorenew"
android:title="Search"/>
<item
android:id="#+id/action_search"
android:orderInCategory="100"
app:showAsAction="always"
android:icon="#drawable/ic_action_search"
android:title="Search"/>
</menu>
and use it in activity
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// MenuInflater inflater1 = getActivity().getMenuInflater();
inflater.inflate(R.menu.cartmenu, menu);
return ;
}
in your res/menu/menu_main.xml:
add
<?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/icon_id"
android:visible="true"
android:title="#string/icon_name"
android:icon="#drawable/your_image"
app:showAsAction="always">
</item>
</menu>
in your activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
// return true so that the menu pop up is opened
return true;
}
To access your menu item in activity add:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.your_item_id) {
// your code
return true;
}
return super.onOptionsItemSelected(item);
}
You can use showAsAction option found at item in menu resource file.
1) If you want to add popup menu then write app:showAsAction="never"
2) If you want to add icons as an action (multiple icons in actionbar) then write app:showAsAction="always"
I have a list of menu items in my actionbar. Each item click should trigger a different method. But onOptionsItemSelected is never called.
This is how the actionbar is defined in MainActivity:
public class MainActivity extends AppCompatActivity {
...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings_1) {
//do something
return true;
} else if (id == R.id.action_settings_2) {
//do something
return true;
} else if (id == R.id.action_settings_1) {
//do something
return true;
}
return super.onOptionsItemSelected(item);
}
...
}
This is the actionbar menu layout menu_main:
<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="com.example.MainActivity">
<item
android:id="#+id/action_settings_1"
android:orderInCategory="1"
android:title="Item 1"
app:showAsAction="never" />
<item
android:id="#+id/action_settings_2"
android:orderInCategory="2"
android:title="Item 2"
app:showAsAction="never" />
<item
android:id="#+id/action_settings_3"
android:orderInCategory="3"
android:title="Item 3"
app:showAsAction="never" />
</menu>
How can I set up the actionbar so that onOptionsItemSelected is called when an actionbar item is clicked?
Inside your onCreateOptionsMenu, return true instead of calling super. That should do it
In the onCreate(), call setSupportActionbar(), like so
toolbar = (Toolbar)findViewById(R.id.main_toolbar);
setSupportActionBar(toolbar);
Just do the change as 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.menu_main, menu);
return true;
}
This problem can potentially also happen if using the menu attribute in XML:
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
app:menu="#menu/your_menu"
app:navigationIcon="#drawable/..."
app:title="#string/..." />
So app:menu="#menu/your_menu" doesn't work with the overridden fragment method onOptionsItemSelected. The menu item click listener has to be set to the Toolbar
private fun setMenuClickListener(toolbar: MaterialToolbar) = with(toolbar) {
setOnMenuItemClickListener { menuItem ->
if (menuItem.itemId == R.id.yourId) {
//do something
return#setOnMenuItemClickListener true
}
//this is a lambda so it can be just false,
//added return to make it explicit
return#setOnMenuItemClickListener false
}
}
So what we are looking for is the setOnMenuItemClickListener from MaterialToolbar
Try this:
Instead of implement
#Override
public boolean onCreateOptionsMenu
...
In activity_main.xml add:
<androidx.appcompat.widget.Toolbar
android:id="#+id/myToolbar"
app:title="#string/myTitle"
app:menu="#menu/menu_main"
>
</androidx.appcompat.widget.Toolbar>
Next, in menu_main.xml add in each item:
android:onClick="onOptionsItemSelected"
Like this:
<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="com.example.MainActivity">
<item
android:id="#+id/action_settings_1"
android:orderInCategory="1"
android:title="Item 1"
app:showAsAction="never"
android:onClick="onOptionsItemSelected" />
<item
android:id="#+id/action_settings_2"
android:orderInCategory="2"
android:title="Item 2"
app:showAsAction="never"
android:onClick="onOptionsItemSelected" />
<item
android:id="#+id/action_settings_3"
android:orderInCategory="3"
android:title="Item 3"
app:showAsAction="never"
android:onClick="onOptionsItemSelected" />
</menu>
I'm trying to use Android ActionBar in my app, and have an option that's hidden away in the overflow menu.
There's a lot of documentation out there, but it's confusing because most of it is only relevant to very old versions of Android, and when you try applying the same concepts, they don't work anymore or work differently.
This is in my Activity layout
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:titleTextColor="#android:color/white"
android:background="#color/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
And this is in my Activity's onCreate() method
// sets up activity toolbar
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
myToolbar.showOverflowMenu();
myToolbar.setTitleTextColor(R.color.lightPrimaryText);
I've also tried inflating a menu xml file from the onCreateOptionsMenu(), but that also didn't give me the results I wanted.
Define a Menu for your Toolbar in the res/menu resource folder, for example:
toolbar_menu.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"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".activity.MainActivity">
<item
android:id="#+id/action_sign_out"
android:title="#string/toolbar_sign_out"
app:showAsAction="never"/>
</menu>
Setting app:showAsAction="never" ensures that this MenuItem will not be shown in the Toolbar, but placed in the overflow menu instead.
The theme of your Activity should be (or derive from) one of the NoActionBar themes (Theme.AppCompat.NoActionBar for example, or Theme.MaterialComponents.NoActionBar if you're using Material Components).
In your Activity, set up your Toolbar:
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
And override onCreateOptionsMenu() to inflate your previously defined menu resource:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.toolbar_menu, menu);
return true;
}
You can override onOptionsItemSelected() to define the onClick behaviour of your MenuItem(s):
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_sign_out: {
// do your sign-out stuff
break;
}
// case blocks for other MenuItems (if any)
}
return true;
}
in manifest file declare
android:theme="#style/AppTheme.NoActionBar"
like this :
<activity
android:name=".ActivityName"
android:label="#string/label"
android:theme="#style/AppTheme.NoActionBar" />
and add this to your style :
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
and call this in Activity onCreate() :
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
override this method in activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.product_list, menu);
//U can find item set icon and stuff...
MenuItem item= menu.findItem(R.id.action_search);
return true;
}
and declare your menu like this for overflow menu:
<?xml version="1.0" encoding="utf-8"?>
<menu >
<group>
<item
android:id="#+id/sign_out"
android:title="#string/sign_out" />
<item
android:id="#+id/about"
android:title="#string/about" />
</group>
</menu>
and for handle item selection call this
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.sign_out:
//do stuff
break;
}
return super.onOptionsItemSelected(item);
}
done :)
Simple do This copy this code on your MainActivet`
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main2, 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_settings) {
Group gp=(Group)findViewById(R.id.order);
return true;
}
return super.onOptionsItemSelected(item);
}`
Now Make Directory file for menu name for this go on Android_Studio->app Folder->Right_Click->New->Directory-> Enter name menu now Create a xml file in there with menu2.xml name
and past this code on menu2.xml file
<?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_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never"
android:icon="#android:drawable/ic_input_add"
/>
</menu>
if any Query Please text me
I tried
#Override
public boolean onCreateOptionsMenu(Menu menu) {
Log.v(
this.getClass().getName() + "!!!",
new Exception().getStackTrace()[0].getMethodName()
);
MenuItem m_item = (MenuItem)menu.findItem(R.id.action_settings);
if(m_item != null)
m_item.setTitle("Back to test");
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.settings, menu);
return true;
}
but it always gets null.And also,onCreate seems to have it as null as well. Is there a function that i can modify the text on it during runtime??? And if so, is there an easy way to find it?
You should add items in the menu xml. You can find it on the folder res/menu. There you have all the menus available for inflation.
I suppose that you have only one. This is how it could look with added options:
<?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/searchMain"
android:icon="#drawable/ic_action_search"
app:showAsAction="ifRoom|withText"
android:title="Search"/>
<item
android:id="#+id/searchBarcodeScan"
android:icon="#drawable/ic_launcher"
app:showAsAction="always|withText"
android:title="Scanner"/>
<item
android:id="#+id/seeList"
android:icon="#drawable/ic_launcher"
app:showAsAction="ifRoom|withText"
android:title="See list"/>
<item
android:id="#+id/settings"
android:icon="#drawable/ic_settings"
app:showAsAction="ifRoom|withText"
android:title="Settings"/>
</menu>
Then in your activity you can react to the option selected by overriding this method and doing things inside it:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.searchMain:
doSomething();
return true;
case R.id.searchBarcodeScan:
doSomething2();
return true;
case R.id.seeList:
doSomething3();
return true;
case R.id.settings:
doSomething4();
return true;
}
return super.onOptionsItemSelected(item);
}
EDIT
In order to change menus in runtime, you should call the method invalidateOptionsMenu(). This method will force the recreation of the menu and this time onPrepareOptionsMenu method will be called. You should override it in your Activity this way:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if(someCondition){
getMenuInflater().inflate(R.menu.main_menu, menu);
}
else if(someOtherCondition){
getMenuInflater().inflate(R.menu.other_menu, menu);
}
return true;
}
Instead of
getMenuInflater().inflate(R.menu.settings, menu);
do something like:
getMenuInflater().inflate(R.menu.menu_custom, menu);
where res/menu/menu_custom.xml is something like:
<?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/menu_search"
android:icon="#drawable/ic_action_search"
android:title="#string/search"/>
<item android:id="#+id/menu_settings"
android:icon="#drawable/ic_action_settings"
android:title="#string/settings" />
</menu>
This will give you two items in the dropdown. It looks like your res/menu/settings.xml only has one item in it.
For some reason, I cannot get my button to appear on the Action Bar. I have defined it in an XML file in /res/menu, along with inflating it and listening for an action. The icon is present in /res/drawable-hdpi. And nothing of interest shows in logcat. :(
XML:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
android:showAsAction="always" />
</menu>
Code in main activity:
public class MainActivity extends ActionBarActivity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.logout:
//logout code
return true;
default:
return super.onOptionsItemSelected(item);
}
}
//rest of app
}
I followed this question for my initial problem, and it didn't help. How to add button in ActionBar(Android)?
Try with this change:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
yourapp:showAsAction="always" />
</menu>
