I have a < button on actionBar beside the app title and a + button.
I create the < button by using code below
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.mipmap.back_to);
and then
#Override
public boolean onCreateOptionsMenu(Menu menu) { // for + button
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.create_new_details, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.home: // back to previous activity, < button
onBackPressed();
break;
case R.id.addDetails:
mClickedPosition = -1;
View menuItemView = findViewById(R.id.addDetails);
PopupMenu po = new PopupMenu(this, menuItemView); //for drop-down menu
po.getMenuInflater().inflate(R.menu.popup_details, po.getMenu());
po.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(getApplication(), "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
if ("Add Work Details".equals(item.getTitle())) {
Intent intent = new Intent(getApplication(), Add_Details_Information.class); // go to Details class
startActivityForResult(intent, PROJECT_REQUEST_CODE);
} else {
}
return true;
}
});
po.show(); //showing popup menu
}
return super.onOptionsItemSelected(item);
}
But only the + button works. How do I back to previous activity when < button is clicked?
Just change R.id.home to android.R.id.home.

I used a library recently that Provides a Floating Action Button and changing to a Something like Navigation bar by clicking on it.
but i cant set click Event for my navigation bar Items.
after Pressing on items i don't see any reaction!
Anyone can help me?

#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();

Toast.makeText(this, "back", Toast.LENGTH_SHORT).show();

First of all you should have to use break whenever you use switch statement otherwise the program will go to default status. so use break; the code below.
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getId(); // Retrieve the id of the selected menu item
switch(id) {
case R.id.back:
newBack();
return true;
break;
case ...
}
return super.onOptionsItemSelected(item);
}

}
and my popup menu is as follows,
<menu xmlns:android="http://schemas.android.com/apk/res/android"

android:showAsAction="ifRoom|withText"/>
</menu>
What i want to do is, when i click on these menu items another activities has to be opened. How could i do that?
Can someone help me please. Thanks in advance.
Use the id to launch the activity using switch statement with menu itemId
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.one:
Intent intent1 =new Intent(this,ActivityOne.class);//firstActivity
startActivity(intent1);
return true;
case R.id.two:
Intent intent2 =new Intent(this,ActivityTwo.class);//second Activity
startActivity(intent2);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Try this
popupMenu.setOnMenuItemClickListener(new OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(getApplicationContext(),
item.getTitle(), Toast.LENGTH_SHORT).show();
return true;
}
});
To open activity on popup menu click:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.menu_item1:
Intent intent = new Intent(this, ActivityForItemOne.class);
this.startActivity(intent);
break;
case R.id.menu_item2:
// another startActivity, this is for item with id "menu_item2"
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
In my Activity, I have two icon button in action bar
This is in add_task.xml
<item
android:id="#+id/action_add_task"
android:icon="#drawable/create_new"
android:title="Add New"
app:showAsAction="always" />
<item
android:id="#+id/menu"
android:icon="#drawable/menu"
android:title="Menu"
app:showAsAction="always" />
When the icon menu is clicked, I get this
popup.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/opt1"
android:icon="#drawable/change_pic"
android:title="Change Profile" />
<item
android:id="#+id/opt2"
android:icon="#drawable/sign_out"
android:title="Sign Out" />
</menu>
My problem is that the Toast get displayed when the menu icon clicked. I want it only display when the change profile is clicked.
#Override
public boolean onCreateOptionsMenu(Menu menu) {

case R.id.menu:
View menuItemView = findViewById(R.id.menu);

MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.popup, menuBuilder);
MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, menuItemView);
optionsMenu.setForceShowIcon(true);
optionsMenu.show();
case R.id.opt1: // when change profile clicked
Toast.makeText(getApplication(),"Profile",Toast.LENGTH_SHORT).show();
default:
return super.onOptionsItemSelected(item);
}
}
Edit
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu:
View menuItemView = findViewById(R.id.menu);
MenuBuilder menuBuilder = new MenuBuilder(this);
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.popup, menuBuilder);
final MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, menuItemView);
opionsMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
// Toast.makeText(MainActivity.this, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
if ("Change Profile".equals(item.getTitle())) {
Intent intent = new Intent(AddMonthlyExpenses.this, Profile.class); // go to Information class
intent.putExtra("name", name);
startActivity(intent);
}
optionsMenu.setForceShowIcon(true);
optionsMenu.show();
return true;
}
});
default:
return super.onOptionsItemSelected(item);
}
return true;
}
I get error on this line
opionsMenu.setOnMenuItemClickListener
optionsMenu cannot be solved.
You have not added Break statement
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch(item.getItemId()){
case R.id.menu:
View menuItemView = findViewById(R.id.menu);
MenuBuilder menuBuilder =new MenuBuilder(this);
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.popup, menuBuilder);
MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, menuItemView);
optionsMenu.setForceShowIcon(true);
optionsMenu.show();
break;
case R.id.opt1: // when change profile clicked
Toast.makeText(getApplication(),"Profile",Toast.LENGTH_SHORT).show();
break;
}
return super.onOptionsItemSelected(item);
}
try this code
Finally I found the answer
case R.id.menu:
View menuItemView = findViewById(R.id.menu);
MenuBuilder menuBuilder = new MenuBuilder(this);
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.popup, menuBuilder);
MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, menuItemView);
optionsMenu.setForceShowIcon(true);
// Set Item Click Listener
menuBuilder.setCallback(new MenuBuilder.Callback() {
#Override
public boolean onMenuItemSelected(MenuBuilder menu, MenuItem item) {
switch (item.getItemId()) {
case R.id.opt1: // Handle option1 Click
Intent intent = new Intent(AddMonthlyExpenses.this,Profile.class);
startActivity(intent);
return true;
case R.id.opt2: // Handle option2 Click
return true;
default:
return false;
}
}
#Override
public void onMenuModeChange(MenuBuilder menu) {}
});
// Display the menu
optionsMenu.show();
A sliding menu was implemented using google navigation drawer with actionbar class. My problem is onCreateOptionsMenu is being shown in every activities. how can i make onCreateOptionsMenu icon visible and invisible at will. Any idea please.
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.layout.menu, menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.settings:
Intent i=new Intent(class1.this, clas2.class);
startActivity(i);
return true;
}
return false;
}
Either you create menu runtime or have different menu layouts as per your need and in onCreateOptionsMenu of your activity set that layout or runtime create those menus or if you want to show no menu icons then just do menu.clear()
Activity A
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.layout.menu_a, menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.settings:
Intent i=new Intent(class1.this, clas2.class);
startActivity(i);
return true;
}
return false;
}
Activity B
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
menu.clear();
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.layout.menu_b, menu);
// OR
Drawable tmpDrawable = getResources().getDrawable(R.drawable.share_sharingicon);
// tmpDrawable.setColorFilter(getResources().getColor(R.color.colorGrayFont), PorterDuff.Mode.MULTIPLY);
menu.add("ShareMap").setIcon(tmpDrawable).setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
menu.add("Directions").setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.ShareMap:
Intent i=new Intent(class1.this, clas2.class);
startActivity(i);
return true;
case R.id.Directions:
Intent i=new Intent(class1.this, clas2.class);
startActivity(i);
return true;
}
return false;
}
To hide or show some icon on action bar, you need override method:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
MenuItem your_icon = menu.findItem(R.id.action_your_icon);
//show icon
your_icon.setvisible(true);
//hide icon
your_icon.setvisible(false);
...
}
Besides you need 'supportInvalidateOptionsMenu()' to Invalidate the activity's options menu when action bar items have some change
I'm building an Android application and I'm trying to build a user management system where users can login, logout, etc. I want to display a login menu item if the user is logged out and a logout button if the user is logged in. How can I do this dynamically?
This is the layout file right now:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/add" android:title="Add" android:icon="#drawable/ic_menu_add"/>
<item android:id="#+id/list" android:title="List" android:icon="#drawable/ic_menu_list"/>
<item android:id="#+id/refresh" android:title="Refresh" android:icon="#drawable/ic_menu_refresh"/>
<item android:id="#+id/login" android:title="Login" android:icon="#drawable/ic_menu_login"/>
</menu>
This is my Java right now:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.activity_main, menu);
return(super.onCreateOptionsMenu(menu));
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
System.out.println(item.getItemId()==R.id.add);
if (item.getItemId()==R.id.add)
{
//Cannot add spot unless we have obtained the users current location.
if((currentLat != 0) && (currentLng != 0))
{
System.out.println("loggedin? : " + auth.isLoggedIn());
if(!auth.isLoggedIn())
{
Toast.makeText(MainActivity.this, "You must be logged in to add a new spot",
Toast.LENGTH_LONG).show();
}
else
{
Intent addIntent = new Intent(MainActivity.this, AddSpot.class);
Bundle b = new Bundle();
b.putDouble("currentLat", currentLat);
b.putDouble("currentLng", currentLng);
addIntent.putExtras(b);
startActivity(addIntent);
return(true);
}
}
}
else if(item.getItemId()==R.id.list)
{
//Pointless showing them a blank screen if nothing is retrieved from the server
if(list != null)
{
Intent listIntent = new Intent(MainActivity.this, ListLocations.class);
listIntent.putExtra("list", list);
startActivity(listIntent);
return(true);
}
}
if(item.getItemId()==R.id.refresh)
{
finish();
startActivity(getIntent());
return(true);
}
if(item.getItemId()==R.id.login)
{
Intent loginIntent = new Intent(MainActivity.this, LoginActivity.class);
startActivity(loginIntent);
return(true);

return(super.onOptionsItemSelected(item));

How to Dynamically Add Menu Items to an Android Activity
public class yourActivity extends Activity {
...
private static final int MENU_ADD = Menu.FIRST;
private static final int MENU_LIST = MENU.FIRST + 1;
private static final int MENU_REFRESH = MENU.FIRST + 2;
private static final int MENU_LOGIN = MENU.FIRST + 3;
/**
* Use if your menu is static (i.e. unchanging)
*/
/*
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, MENU_ADD, Menu.NONE, R.string.your-add-text).setIcon(R.drawable.your-add-icon);
menu.add(0, MENU_LIST, Menu.NONE, R.string.your-list-text).setIcon(R.drawable.your-list-icon);
menu.add(0, MENU_REFRESH, Menu.NONE, R.string.your-refresh-text).setIcon(R.drawable.your-refresh-icon);
menu.add(0, MENU_LOGIN, Menu.NONE, R.string.your-login-text).setIcon(R.drawable.your-login-icon);
return true;
}
*/
/**
* Gets called every time the user presses the menu button.
* Use if your menu is dynamic.
*/
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.clear();
if(enableAdd)
menu.add(0, MENU_ADD, Menu.NONE, R.string.your-add-text).setIcon(R.drawable.your-add-icon);
if(enableList)
menu.add(0, MENU_LIST, Menu.NONE, R.string.your-list-text).setIcon(R.drawable.your-list-icon);
if(enableRefresh)
menu.add(0, MENU_REFRESH, Menu.NONE, R.string.your-refresh-text).setIcon(R.drawable.your-refresh-icon);
if(enableLogin)
menu.add(0, MENU_LOGIN, Menu.NONE, R.string.your-login-text).setIcon(R.drawable.your-login-icon);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch (item.getItemId()) {
case MENU_ADD: doAddStuff(); break;
case MENU_LIST: doListStuff(); break;
case MENU_REFRESH: doRefreshStuff(); break;
case MENU_LOGIN: doLoginStuff(); break;
}
return false;
}
The following specific example adds a MENU_LOGOUT option if the user is logged in.
private static final int MENU_LOGOUT = MENU.FIRST + 4;
public boolean onPrepareOptionsMenu(Menu menu) {
...
if(auth.isLoggedIn()) {
menu.add(0, MENU_LOGOUT, Menu.NONE, R.string.your-logout-text).setIcon(R.drawable.your-logout-icon);
}
...
}
public boolean onOptionsItemSelected(MenuItem item) {
...
case MENU_LOGOUT:
if(auth.isLoggedIn()) {
doLogout();
} else {
Toast.makeText(this, "You must have somehow been logged out between the time the menu button was pressed and now.", Toast.DURATION_LONG).show();
}
break;
...
}
That's all there is to it.
In my case the menu items are in the ArrayList , - try this Hope it will help u :)
public void onClick(View v)
{
PopupMenu menu = new PopupMenu(DialogCheckBox.this, v);
for (String s : limits) { // "limits" its an arraylist
menu.getMenu().add(s);
}
menu.show();
}
you can call invalidateOptionsMenu() (note:need to use compatability library like actionBarSherlock to access in case you need to support low API versions) , and then update the menu items according to the status.
there you could hide the login action item and show the logout action item.
you might also try update the icon itself but i never tried it.
private void getPopup(final TextView textView, ArrayList<String> arrayList) {
final PopupMenu popupMenu = new PopupMenu(sContext, textView);
for (int i = 0; i < arrayList.size(); i++) {
popupMenu.getMenu().add(arrayList.get(i));
}
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
textView.setText(item.getTitle());
return false;
}
});
popupMenu.show();
}
Simple way to create menu items :
Dynamic_PopUpMenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
PopupMenu menu = new PopupMenu(DialogCheckBox.this, v);
menu.getMenu().add("AGIL"); // menus items
menu.getMenu().add("AGILANBU"); // menus items
menu.getMenu().add("AGILarasan");
menu.getMenu().add("Arasan");
menu.show();
}
});
Try this :)
it's so easy
To create the menu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
for (int i = 0; i < list.size(); i++) {
menu.add(0, i, 0, "Menu Name").setShortcut('5', 'c');
}
return true;
}
to get the details from clicked menu
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId(); //to get the selected menu id
String name = item.getTitle(); //to get the selected menu name
return super.onOptionsItemSelected(item);
}
