Custom Menu on button click as drop down

Question

I am trying to implement the action bar functionality of the flipkart app.

.

For this I have successfully created a custom Action Bar but I am facing problems in showing the menu as drop down on overflow icon click.

If I try Android Option Menu on button click then on I am getting the menu without icons (4.2.2) at the bottom center of my screen. Using a custom dialog or alert dialog fades the background and they also appear on the center of the screen.

What should I do to get the functionality similar as shown in the image above?

A simple way I have is put the overflow menu by you and add all those menu as sub menu in that, by that way you achieve this view. Also this overflow menu display as always in your ActionBar

<item
    android:icon="@drawable/ic_action_overflow"
    android:showAsAction="always">
    <menu>

        <item
            android:id="@+id/menu_login"
            android:icon="@drawable/login"
            android:title="login"/>
    </menu>
</item>

You can easily use ListPopupWindow and any convenient for you adapter:

// create any adapter with any data, just as for ordinary ListView
    SimpleAdapter simpleAdapter= new SimpleAdapter(this, dataSet, android.R.layout.simple_list_item_2,
                            new String[] {"Name", "Tel. no."},
                            new int[] {android.R.id.text1, android.R.id.text2});

ListPopupWindow listPopup = new ListPopupWindow(this); // feed context to ListPopupWindow
listPopup.setAdapter(simpleAdapter); // set adapter to created ListPopupMenu

listPopup.setAnchorView(findViewById(id)); 
// id - any id of any view on the screen. Under this view popup appears. It may be MenuItem as well

listPopup.setWidth(getWidestView(simpleAdapter)); 
// as popup width equals the anchor width, use getWidestView method for proper list displaying. 
// ListPopupWindow.WRAP_CONTENT won't work here

listPopup.show();

getWidestView snippet you can find here: https://stackoverflow.com/a/13959716/4890659

If you're looking for a more Material popup menu and are not afraid of Kotlin you could try: https://github.com/zawadz88/MaterialPopupMenu - there's no need to declare menus in XML and you could handle clicks more easily.

The only way that I could get the icons to show was by calling setForceIcons before inflating the menu.

/**
 * Make a call to setForceIcons to cause icons to show.
 *
 * @param popup
 */
public static void showForceIcons (final PopupMenu popup)
{
    try {
        Field[] fields = popup.getClass().getDeclaredFields();
        for (Field field : fields) {
            if ("mPopup".equals(field.getName())) {
                field.setAccessible(true);
                Object menuPopupHelper = field.get(popup);
                Class<?> classPopupHelper = Class.forName(menuPopupHelper.getClass().getName());
                Method setForceIcons = classPopupHelper.getMethod("setForceShowIcon", boolean.class);
                setForceIcons.invoke(menuPopupHelper, true);
                break;
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
