Creating Simple Popup Menu

First create a button on main activity

<Button

    android:layout_width="150dp"

    android:layout_height="wrap_content"

    android:text="View Popup Menu"

    android:textSize="20sp"

    android:textColor="#fff"

    android:textStyle="bold"

    android:background="@color/colorPrimaryDark"

    android:onClick="ShowPopup"

    android:textAllCaps="false"

    android:layout_gravity="center"

    />

Now in res directory create new directory for menu named as menu

Then create popup_menu in menu directory and then implement following code

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android">



    <item android:id="@+id/vuimg"

        android:title="View Image"/>

    <item android:id="@+id/nuimg"

        android:title="New Image"/>



</menu>

Now go to main activity and create method named as ShowPopup for button

public void ShowPopup(View v){

    PopupMenu popupMenu = new PopupMenu(this,v);

    popupMenu.getMenuInflater().inflate(R.menu.popup_menu,popupMenu.getMenu());

    popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {

        @Override

        public boolean onMenuItemClick(MenuItem item) {

            Toast.makeText(MainActivity.this,""+item.getTitle(),Toast.LENGTH_SHORT).show();

   switch (item.getItemId()){

    case R.id.vuimg:

        getPicFromGallery();

        return true;

    case R.id.nuimg:

        camerOpenForPic();

        return true;

    default: return false;

        }

    });

    popupMenu.show();

}
