DroppyMenuPopup.Builder droppyBuilder = new DroppyMenuPopup.Builder(MyActivity.this, anchor);

// Add normal items (text only)
droppyBuilder.addMenuItem(new DroppyMenuItem("test1"))
    .addMenuItem(new DroppyMenuItem("test2"))
    .addSeparator();

// Add Item with icon
droppyBuilder.addMenuItem(new DroppyMenuItem("test3", R.drawable.ic_launcher));

// Add custom views
DroppyMenuCustomView sBarItem = new DroppyMenuCustomView(R.layout.slider);
droppyBuilder.addMenuItem(sBarItem);

// Set Callback handler
droppyBuilder.setOnClick(new DroppyClickCallbackInterface() {
    @Override
    public void call(View v, int id) {
        Log.d("Clicked on ", String.valueOf(id));
    }
});
        
DroppyMenuPopup droppyMenu = droppyBuilder.build();

// Then once you click on the button it'll show

Generate From Menu Resource (XML)

given: src/main/res/menu/droppy.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.shehabic.droppy_samples.MainActivity">
    <group android:enabled="true">
        <item
            android:id="@+id/dropp1"
            android:title="Xml Item 1"
            />

        <item
            android:id="@+id/droppy2"
            android:title="Xml Item 2"
            />
    </group>
    <group android:enabled="true">
        <item
            android:id="@+id/dropp3"
            android:icon="@drawable/ic_launcher"
            android:title="Xml Item 3"
            />

        <item
            android:id="@+id/droppy4"
            android:icon="@drawable/ic_launcher"
            android:title="Xml Item 4"
            />
    </group>
</menu>

We generate the menu as follows:

DroppyMenuPopup droppyMenu;
DroppyMenuPopup.Builder droppyBuilder = new DroppyMenuPopup.Builder(this, btn);
DroppyMenuPopup droppyMenu = droppyBuilder.fromMenu(R.menu.droppy)
    .triggerOnAnchorClick(false)
    .setOnClick(new DroppyClickCallbackInterface() {
        @Override
        public void call(View v, int id) {
            Log.d("Id:", String.valueOf(id));
        }
    })
    .setOnDismissCallback(DroppyMenuPopup.OnDismissCallback() {
        @Override
        public void call()
        {
            Toast.makeText(this, "Menu dismissed", Toast.LENGTH_SHORT).show();
        }
     })
    .setPopupAnimation(new DroppyFadeInAnimation())
    .setXOffset(5)
    .setYOffset(5)
    .build();
droppyMenu.show();

How it looks like

Why not the native PopupMenu?

Well if you have struggled long enough trying to show an icon beside the text in the normal popup menu or wanted to created a simple popup with custom view yest still contextual to an exisitng view, you would've know that it was almost impossible to do with the normal popup menu unless you use reflection and hack a the internal properties for PopupMenu and yet just add extra icon but not a fully customized view.
