Android popup menu

---

A PopupMenu displays a Menu in a modal popup window anchored to a View. The popup will appear below the anchor view if there is room, or above it if there is not. If the IME is visible the popup will not overlap it until it is touched. Touching outside of the popup will dismiss it.

Step 1: layout_popup.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="62dp"
        android:layout_marginTop="50dp"
        android:text="Show Popup" />
</LinearLayout>

Step 2: menu.xml

It contains five items . It is created inside the res/menu directory.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/one"
        android:title="One"/>

    <item
        android:id="@+id/two"
        android:title="Two"/>

    <item
        android:id="@+id/three"
        android:title="Three"/>
    <item
        android:id="@+id/four"
        android:title="Four"/>
    <item
        android:id="@+id/five"
        android:title="Five"/>
</menu>

Step 3: Activity Class

import android.app.Activity;
import android.os.Bundle;
import android.support.v7.widget.PopupMenu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class PopupDemoActivity extends Activity {

    Button btnPopup;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
            setContentView(R.layout.layout_popup);
        btnPopup=(Button)findViewById(R.id.button1);

        btnPopup.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               //Creating the instance of PopupMenu
                PopupMenu popup = new PopupMenu(PopupDemoActivity.this, btnPopup);
                //Inflating the Popup using xml file
                popup.getMenuInflater().inflate(R.menu.menu, popup.getMenu());

                //registering popup with OnMenuItemClickListener
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(PopupDemoActivity.this, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });
                popup.show();
            }
        });
    }
}
