+![](ActionBar_MenuItemIcon_ActionAlways_PopupMenu_Android_Github_gif.gif)
+
+## Introduction
+
+The purpose of this app is to show how to display icon in action bar using menu resource xml file and how to display popup menu.
+
+### Note: 
+
+In these projects we have inflate menu items using xml & java file :
+
+* [ActionBar_OptionMenu_Xml_Android_Github.](https://github.com/amansharma-dev/ActionBar_OptionMenu_Xml_Android_Github/ "ActionBar_OptionMenu_Xml_Android_Github.")
+* [ActionBar_OptionMenu_Java_RunTime_Android_Github.](https://github.com/amansharma-dev/ActionBar_OptionMenu_Java_RunTime_Android_Github/ "ActionBar_OptionMenu_Java_RunTime_Android_Github.")
+
+## Display Icon
+
+Right Click on res directory
+
+> New
+>> Android Resource File
+
+Make sure you select Resource type as Menu.
+
+We name it **menu_main.xml**.
+
+In **menu_main.xml** :
+
+```
+<item
+        android:id="@+id/action_menu"
+        android:title="@string/menu"
+        app:showAsAction="always"
+        android:icon="@drawable/ic_direction"
+        />
+```
+
+Make sure you add this line of code `android:icon="@drawable/ic_direction"` & `app:showAsAction="always"` to add a icon on action bar menu.
+
+#### Now Take Refrence from this project and follow the steps [ActionBar_OptionMenu_Xml_Android_Github.](https://github.com/amansharma-dev/ActionBar_OptionMenu_Xml_Android_Github/ "ActionBar_OptionMenu_Xml_Android_Github.")
+
+## Display Popup Menu on onClick Button
+
+Right Click on res directory
+
+> New
+>> Android Resource File
+
+Make sure you select Resource type as Menu.
+
+We name it **popup_menu.xml**.
+
+In **popup_menu.xml** :
+
+```
+<item
+        android:id="@+id/action_menuOne"
+        android:title="@string/menu_one"
+        android:orderInCategory="101"
+        />
+
+    <item
+        android:id="@+id/action_menuTwo"
+        android:title="@string/menu_two"
+        android:orderInCategory="102"
+        />
+
+    <item
+        android:id="@+id/action_menuThree"
+        android:title="@string/menu_three"
+        android:orderInCategory="103"
+        />
+
+```
+
+Now in **MainActivity** add a onClickListener on Button, i have done it in **main_activity.xml** by adding this line of code `android:onClick="popupMenuButton"` to a Button
+
+To display Popup Menu on onClick of a Button add this piece of code inside `public void popupMenuButton(View view){ }`
+
+```
+PopupMenu popupMenu = new PopupMenu(this,view);
+        popupMenu.getMenuInflater().inflate(R.menu.popup_menu,popupMenu.getMenu());
+
+        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
+            @Override
+            public boolean onMenuItemClick(MenuItem item) {
+                int id = item.getItemId();
+                switch (id){
+                    case R.id.action_menuOne:
+                        Toast.makeText(getApplicationContext(), "Menu 1 Clicked", Toast.LENGTH_SHORT).show();
+                        break;
+
+                    case R.id.action_menuTwo:
+                        Toast.makeText(getApplicationContext(), "Menu 2 Clicked", Toast.LENGTH_SHORT).show();
+                        break;
+
+                    case R.id.action_menuThree:
+                        Toast.makeText(getApplicationContext(), "Menu 3 Clicked", Toast.LENGTH_SHORT).show();
+                        break;
+                        
+                        }
+
+                return false;
+            }
+        });
+        
+        popupMenu.show();
+                        
+```
