Two ways to create an Android menu and add an icon to a menu item

Two ways to create a menu:

1. Create a menu in the XML file:

Specific code:

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

Xmlns:tools= "Http://schemas.android.com/tools"

tools:context= "Com.xunfang.menucreate.MainActivity" >

//Create sub-menu here

<item

Android:id= "@+id/sms"

android:icon= "@drawable/sms"

android:orderincategory= "100"

Android:showasaction= "Never"

android:title= "SMS" >

<menu>

<item

Android:id= "@+id/smsfamily"

android:icon= "@drawable/smsalt"

android:orderincategory= "100"

Android:showasaction= "Never"

android:title= "Home sms"/>

<item

Android:id= "@+id/smscompany"

android:icon= "@drawable/twitteralt"

android:orderincategory= "100"

Android:showasaction= "Never"

android:title= "Company SMS"/>

</menu>

</item>

<item

Android:id= "@+id/camera"

android:icon= "@drawable/camera"

android:orderincategory= "100"

Android:showasaction= "Never"

android:title= "Camera"/>

</menu>

In this case, when creating a menu, you need to use the item tag to create a menu option, you must use an item

When you need to create a submenu : As part of the background color, create a submenu under the main menu, you need to nest a menu tag in item, then write a submenu in the Menu tab, and each submenu is written in the Item tab.

2. Create a menu dynamically:

public boolean Oncreateoptionsmenu (Menu menu) {

Create a submenu for a file

submenu sub = Menu.addsubmenu (Menu.first, 1, 1, "file");

Sub.add (menu.first+3, 10, 1, "hidden Group 3");

Sub.add (menu.first+3, 11, 2, "display Group 3");

menu.add (menu.first,2,2, "edit");

Sub.seticon (r.drawable.browser);

Sub.setheadericon (r.drawable.browser);

MenuItem refactor = menu.add (Menu.first + 1,3,10, "refactoring");

Refactor.seticon (r.drawable.clock);

MenuItem Source = menu.add (Menu.first + 1,4,6, "source code");

Source.seticon (r.drawable.sms);

menu.add (Menu.first + 2, 5, 5, "navigation");

menu.add (Menu.first + 2,6,3, "search");

return true;

}

The four parameters in the Add () method above are: The first parameter indicates that it is in the same group

The second parameter represents a unique ID

The third parameter is an ID that represents the order in which the menu item is displayed in the menu

The fourth parameter represents the displayed text

Note: Add an icon to the menu item:

private void Seticonvisible (Menu menu) {

try {

Class clazz = Class

. forname ("Com.android.internal.view.menu.MenuBuilder");

Method m = Clazz.getdeclaredmethod ("Setoptionaliconsvisible",

Boolean.class);

m.setaccessible (true);

M.invoke (menu, true);

} catch (Exception e) {

e.printstacktrace ();

}

}

The background part is the key part of the code, the above method is my own add a method, in the Add icon only need to call this method on the line.
