Let's do fun with code:


CREATE NEW PROJECT
We need:

1) main.xml located here ...res/menu
1) activity_main.xml
2) MainActivity.java

 Step 1: Write code into main.xml


<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/action_settings"/>
    <item
        android:id="@+id/one"
        android:title="Rename"/>
    <item
        android:id="@+id/two"
        android:title="Delete"/>
    <item
        android:id="@+id/three"
        android:title="Copy"/>

</menu>

Step 2: write code into activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btclickme"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Click Me" />


</LinearLayout>

Step 3: Write code into MainActivity.java

package dev.androidapplink.custommenuapp;

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

public class MainActivity extends Activity {
// create variable
Button btnclickme;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// load control
btnclickme = (Button) findViewById(R.id.btclickme);

btnclickme.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// Create the instance of Menu
PopupMenu popup = new PopupMenu(MainActivity.this, btnclickme);
// Inflating menu using xml file
popup.getMenuInflater().inflate(R.menu.main, popup.getMenu());

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

}
