Based on the Android implementation click a button to let the menu options from the button around the location pop-up _android

Android Material Design:popupmenu

The Android Material Design introduces a popupmenu similar to the context menu in the past, but more flexible. As shown in the figure:

Now give the code to implement the figure PopupMenu. This example is an ordinary button-triggered pop-up popupmenu.

Mainactivity.java of the test:

Package zhangphil.materialdesign; 
Import android.app.Activity; 
Import Android.os.Bundle; 
Import Android.support.v.widget.popupmenu; 
Import Android.view.MenuItem; 
Import Android.view.View; 
Import Android.widget.Button;  
Import Android.widget.Toast; public class Mainactivity extends activity {@Override protected void onCreate (Bundle savedinstancestate) {Supe 
    R.oncreate (savedinstancestate);  
    Setcontentview (R.layout.activity_main); 
    Final button button = (button) Findviewbyid (R.id.button); Button.setonclicklistener (New View.onclicklistener () {@Override public void OnClick (View v) {Show 
      PopupMenu (button); 
  } 
    }); } private void ShowPopupMenu (view view) {//view the position of the relative View displayed by the current popupmenu popupmenu popupmenu = new PopupMenu  
    (this, view);  
    Menu Layout Popupmenu.getmenuinflater (). Inflate (R.menu.main, Popupmenu.getmenu ()); menu item Click event Popupmenu.setonmenuitemclicklistener (New Popupmenu.onmenUitemclicklistener () {@Override public boolean Onmenuitemclick (MenuItem item) {Toast.maketext 
        ApplicationContext (), Item.gettitle (), Toast.length_short). Show (); 
      return false;  
     } 
    }); PopupMenu Shutdown Event Popupmenu.setondismisslistener (new Popupmenu.ondismisslistener () {@Override public void Ondismiss (PopupMenu menu) {Toast.maketext (Getapplicationcontext (), close PopupMenu, Toast.length_short). Show 
      (); 
  
     } 
     }); 
   Popupmenu.show ();
}} package zhangphil.materialdesign;
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 Mainactivity extends activity {@Override protected void onCreate (Bundle savedinstancestate) {Super.oncre
 Ate (savedinstancestate);
 Setcontentview (R.layout.activity_main); Final button button = (Button) Findviewbyid (R.id.button); Button.setonclicklistener (New View.onclicklistener () {@Override public void OnClick (View v) {showpopupmenu (button)
  ;
 }
 }); } private void ShowPopupMenu (view view) {//view the position of the relative View displayed by the current popupmenu popupmenu popupmenu = new PopupMenu (This, view
 );
 Menu Layout Popupmenu.getmenuinflater (). Inflate (R.menu.main, Popupmenu.getmenu ()); menu item Click event Popupmenu.setonmenuitemclicklistener (New Popupmenu.onmenuitemclicklistener () {@Override public bool EAN Onmenuitemclick (MenuItem Item) {Toast.maketext (Getapplicationcontext (), Item.gettitle (), Toast.length_short).
  Show ();
  return false;
 }
 }); PopupMenu Shutdown Event Popupmenu.setondismisslistener (new Popupmenu.ondismisslistener () {@Override public void Ondismiss P
  Opupmenu menu) {Toast.maketext (Getapplicationcontext (), "Close PopupMenu", Toast.length_short). Show ();
 }
 });
 Popupmenu.show (); }
}

The Activity_main layout file that Mainactivity.java needs contains only one ordinary Android Button, which is not included in the time.

Main.xml in the menu directory:

<menu xmlns:android= "http://schemas.android.com/apk/res/android" 
   xmlns:app= "http://schemas.android.com/ Apk/res-auto " 
   xmlns:tools=" Http://schemas.android.com/tools "> 
   <item 
     android:id=" @+id/action_ Open " 
     android:orderincategory=" 
     android:title= " 
     app:showasaction=" never/> 
  <item 
    android:id= "@+id/action_new" 
    android:orderincategory= " 
    android:title=" new 
    app: showasaction= "Never"/> 
  <item 
    android:id= 
    "@+id/action_del" android:title= "Delete" 
     app:showasaction= "never"/>
