Popup Menu in Android With Example

Popup Menu in Android With Example

A PopupMenu in Android is used to display a list of items in a vertical list anchored to a view. It's often used for providing additional actions related to a view, especially when the UI space is limited.

Here's how you can create a PopupMenu:

1. Define the Menu Items:

Create a new XML resource file (e.g., popup_menu.xml) in your res/menu directory.

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/action_option1" android:title="Option 1"/> <item android:id="@+id/action_option2" android:title="Option 2"/> <item android:id="@+id/action_option3" android:title="Option 3"/> </menu>

2. Create and Show the PopupMenu:

// Assuming this code is inside an Activity or Fragment val anchorView: View = findViewById(R.id.anchor_button) // the view to which the popup menu should be anchored anchorView.setOnClickListener { // Create a PopupMenu val popupMenu = PopupMenu(this, anchorView) // Inflate the menu from the XML resource popupMenu.menuInflater.inflate(R.menu.popup_menu, popupMenu.menu) // Set a click listener popupMenu.setOnMenuItemClickListener { menuItem -> when (menuItem.itemId) { R.id.action_option1 -> { Toast.makeText(this, "Option 1 clicked", Toast.LENGTH_SHORT).show() true } R.id.action_option2 -> { Toast.makeText(this, "Option 2 clicked", Toast.LENGTH_SHORT).show() true } R.id.action_option3 -> { Toast.makeText(this, "Option 3 clicked", Toast.LENGTH_SHORT).show() true } else -> false } } // Show the menu popupMenu.show() }

3. (Optional) Styling the PopupMenu:

You can style the PopupMenu by creating a custom theme in your styles.xml and applying it to the PopupMenu.

Example:

<style name="MyPopupMenu" parent="Theme.AppCompat.Light.DarkActionBar"> <item name="android:textColor">@color/my_text_color</item> <item name="android:background">@color/my_background_color</item> <!-- Add more styling attributes if needed --> </style>

And apply it:

val popupMenu = PopupMenu(this, anchorView, 0, 0, 0, R.style.MyPopupMenu)

With this, you've created a simple PopupMenu in Android, added items to it, and provided actions for when each item is clicked.

Examples

  1. Creating Popup Menu in Android example code:

    // Create a button or any view Button popupButton = findViewById(R.id.popup_button); // Set the click listener popupButton.setOnClickListener(v -> { PopupMenu popupMenu = new PopupMenu(this, v); popupMenu.getMenuInflater().inflate(R.menu.popup_menu, popupMenu.getMenu()); // Set item click listener if needed // Show the PopupMenu popupMenu.show(); });

  2. Customizing Popup Menu in Android:

    You can customize a Popup Menu by inflating a custom layout:

    PopupMenu popupMenu = new PopupMenu(this, v); MenuInflater inflater = popupMenu.getMenuInflater(); inflater.inflate(R.menu.custom_popup_menu, popupMenu.getMenu());

  3. PopupMenu with icons in Android example:

    Include icons in your menu XML:

    <item android:id="@+id/menu_item" android:icon="@drawable/ic_icon" android:title="Menu Item" />

  4. Android Popup Menu with RecyclerView:

    Handle item click on RecyclerView and show PopupMenu:

    recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(context, (view, position) -> { PopupMenu popupMenu = new PopupMenu(context, view); popupMenu.inflate(R.menu.recycler_view_popup_menu); // Handle item click popupMenu.show(); }));

  5. PopupMenu on long press in Android:

    Use a long press listener:

    view.setOnLongClickListener(v -> { PopupMenu popupMenu = new PopupMenu(context, v); popupMenu.inflate(R.menu.long_press_popup_menu); // Handle item click popupMenu.show(); return true; });

  6. PopupMenu with fragments in Android example:

    You can show a PopupMenu from a Fragment in a similar way as from an Activity.

  7. PopupMenu gravity in Android example:

    Set the gravity when creating the PopupMenu:

    PopupMenu popupMenu = new PopupMenu(context, anchorView, Gravity.END);

  8. PopupMenu item click listener in Android:

    Set a listener for item clicks:

    popupMenu.setOnMenuItemClickListener(item -> { // Handle item click return true; });

  9. PopupMenu styling in Android:

    Customize the PopupMenu appearance using styles:

    Context wrapper = new ContextThemeWrapper(context, R.style.PopupMenuStyle); PopupMenu popupMenu = new PopupMenu(wrapper, anchorView);
