Where to add menu to work in all activities

I have a menu.xml and the code to show the menu in action bar. Do i have to add the code in every activity? Cause after this i use a switch case to get click, and more code, so i dont thing its the wright way to copy-paste the same code in every activity
#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;
Is there a better way to do it as to work in all app (all activities)?

Create a BaseActivity class.
public class BaseActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
}
Now all activities that extend your base activity will have the same menu.

this is a guide for Android Menu
this is an example menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_game"
android:icon="#drawable/ic_new_game"
android:title="#string/new_game" />
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
And then inflating it within your activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
}
whe item clicked:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.new_game:
newGame();
return true;
case R.id.help:
showHelp();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
good luck and read the doc official for android

How to add search and checkbox icon with their functions in android action bar?

I want to add a searchview and checkbox into action bar menu. And this checkbox will be visible if searchview is opened. And in it's opposite case it will be hidden. How I can do this?
I do something below . But it doesnt work correctly. I want hide checkbox (In my notes) when searchview is closed.
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">
<item
android:id="#+id/search_button"
android:icon="#drawable/ic_icon_search"
android:title="Arama"
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView">
</item>
<item
android:id="#+id/search_in_my_notes_checkbox"
app:showAsAction="ifRoom"
android:title="#string/search_in_my_notes"
android:checkable="true"
android:visible="false"
/>
</menu>
HomeActivity.java
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == R.id.search_button){
MenuItem searchInMyNotesCheckbox = (MenuItem)menu.findItem(R.id.search_in_my_notes_checkbox);
searchInMyNotesCheckbox.setVisible(true);
}
return super.onOptionsItemSelected(item);
}

I found an alternative solution. I will use two checkbox image with checked and unchecked. And I will override onCreateOptionsMenu like this :
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
this.menu = menu;
getMenuInflater().inflate(R.menu.menu, menu);
MenuItem search = (MenuItem)menu.findItem(R.id.search_button2);
final MenuItem searchInMyNotesCheckbox = (MenuItem) menu.findItem(R.id.search_in_my_notes_checkbox);
MenuItemCompat.setOnActionExpandListener(search,
new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem menuItem) {
// Return true to allow the action view to expand
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem menuItem) {
MenuItem searchInMyNotesCheckbox = (MenuItem) menu.findItem(R.id.search_in_my_notes_checkbox);
searchInMyNotesCheckbox.setVisible(false);
return true;
}
});
searchInMyNotesCheckbox.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if(item.getIcon() == R.drawable.checked_checkbox){
item.setIcon(R.drawable.unchecked_checkbox);
}
else {
item.setIcon(R.drawable.checked_checkbox);
}
return false;
}
});
return super.onCreateOptionsMenu(menu);
}

How to change the menubar Icon when pressed in Android

Here i am having menu bar with two items called notification_icon and favourite_icon when i pressed favourite_icon that should be changed as favourite_icon2.So that i have tried selector. Selector only works for android:state_pressed="true" not android:state_selected="true". s Please guide me to do that.Here i have added the following code for your refreence
menu_clg.xml (under menu)
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:appmunu="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".UserDashBoardFragment">
<item
android:id="#+id/action_notify"
android:icon="#drawable/mail_icon"
appmunu:showAsAction="always"
android:title="Notification" />
<item
android:id="#+id/action_favourite"
android:icon="#drawable/icon_selector"
appmunu:showAsAction="always"
android:title="Favourite" />
</menu>
this is icon_selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="true"
android:drawable="#drawable/vijay"
/>
<item
android:state_selected="false"
android:drawable="#drawable/favourite_icon"
/>
</selector>
this is activity code
#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_clg, menu);
mMenu = menu;
return true;
}
// delete the selected event from event list added here
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_notify:
navigatetoNotification();
return true;
case R.id.action_favourite:
favouriteClg();
return true;
}
return super.onOptionsItemSelected(item);
}

Now, what we want to do is, when the user clicks on the add icon “+” we will add a new item and change the add icon to remove “X” icon.
onOptionsItemSelected() will be called when a user clicks on an item.
onOptionsItemSelected(MenuItem item) MenuItem object is passed as a parameter which is a reference to the clicked item. Using this object we can know which item has been clicked.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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;
}
boolean canAddItem = false;
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == R.id.action_addItem){
// ( 1 ) add a new item
// ( 2 ) change add to remove
}
else{
// if a the new item is clicked show "Toast" message.
}
return super.onOptionsItemSelected(item);
}
}
We need to call onPrepareOptionsMenu(Menu menu) to add, remove and modify menu items.
On Android 2.3.x and lower, the system calls onPrepareOptionsMenu() each time the user opens the options menu (presses the Menu button).
On Android 3.0 and higher, we need to call invalidateOptionsMenu() to request that the system call onPrepareOptionsMenu().
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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;
}
boolean canAddItem = false;
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Toast toast;
if(item.getItemId() == R.id.action_addItem){
invalidateOptionsMenu();
}
else{
toast = Toast.makeText(this, item.getTitle()+" Clicked!", Toast.LENGTH_SHORT);
toast.show();
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if(canAddItem){
menu.getItem(0).setIcon(R.drawable.ic_content_remove);
MenuItem mi = menu.add("New Item");
mi.setIcon(R.drawable.ic_location_web_site);
mi.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM);
canAddItem = false;
}
else{
menu.getItem(0).setIcon(R.drawable.ic_content_new);
canAddItem = true;
}
return super.onPrepareOptionsMenu(menu);
}
}
Hope it helps.

How make an app without menu? Android

I use this for change the menu:
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_log_in, menu);
return true;
}
but...
If i want that my activity haven't menu, how make it?
I want make activities without menu because i don't have navigation in this scenes. How make it?

Remove these two methods in your Activity:
#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_del, 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) {
return true;
}
return super.onOptionsItemSelected(item);
}

OnMenuItemSelected isn't called when layout is set for menu item

I have a menu which is inflated from main_menu.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/act_sync"
android:showAsAction="always"
android:actionLayout="#layout/sync_action"
android:icon="#android:drawable/ic_popup_sync" />
</menu>
and here is the code in the activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
MyMessageHandler.debug("menu item selected");
switch(item.getItemId()){
case R.id.act_sync:
sync();
return true;
}
return super.onOptionsItemSelected(item);
}
But onOptionsItemSelected is not called when I touch the menu item. When I remove the actionLayout attribute of the menu item, it works fine. How can I fix this? Thanks.

you should use below snippet ( Just for reference )
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
final Menu m = menu;
final MenuItem item = menu.findItem(R.id.ActionConnection);
item.getActionView().setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
sync();
}
});
return true;
}

In addition to the answer provided by Vipul Shah.
Make sure you disable the clickable option of all items in your action layout:
android:clickable="false"
Otherwise, it may steal the click so that you still cant receive onClick call back.
