【中文标题】以编程方式设置 PopupMenu 菜单项【英文标题】:Setting PopupMenu menu items programmatically 【发布时间】:2012-11-26 20:54:17 【问题描述】:

我有一个PopupMenu,我知道将菜单与其关联的常用方法是使用popup.getMenuInflater().inflate(R.menu.my_menu, popup.getMenu()); 或类似的东西。我的问题是,我在菜单中有一组我想要的项目,我需要能够在 Java 中以编程方式更改它们。我怎样才能做到这一点?

【问题讨论】:

【参考方案1】:

刚刚想通了;对于遇到同样问题的任何人,您只需这样做:

popup.getMenu().add(groupId, itemId, order, title);

对于您要添加的每个MenuItem

【讨论】:

【参考方案2】:

只需创建弹出菜单,注册弹出窗口将在下面显示的视图,然后使用 getMenu() 方法添加值。不要忘记调用 show();

PopupMenu menu = new PopupMenu(this, view);

menu.getMenu().add("titleRes");
menu.show();

【讨论】:

【参考方案3】:

试试这个:

Dynamic_PopUpMenu.setOnClickListener(new View.OnClickListener() 
    @Override
    public void onClick(View v) 
        PopupMenu menu = new PopupMenu(DialogCheckBox.this, v);
        menu.getMenu().add("AGIL");         
        menu.getMenu().add("AGILarasan");
        menu.getMenu().add("Arasan");
        menu.show();
    
);

【参考方案4】:

在 popupmenu.xml 中定义 ids

<?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

        <item
            android:id="@+id/slot1"
            app:showAsAction="ifRoom|withText"
            android:title="Movies"
            android:visible="true"/>
        <item
            android:id="@+id/slot2"
            app:showAsAction="ifRoom|withText"
            android:title="Music"
            android:visible="true"/>
        <item
            android:id="@+id/slot3"
            app:showAsAction="ifRoom|withText"
            android:title="Comedy"
            android:visible="true"/>

</menu>  

PopupMenu popupMenu = new PopupMenu(FullMenuActivity.this, view);                      
popupMenu.setOnMenuItemClickListener(FullMenuActivity.this);
popupMenu.getMenu().add(1, R.id.slot1, 1, "slot1");
popupMenu.getMenu().add(1,R.id.slot2,2,"slot2");
popupMenu.getMenu().add(1,R.id.slot3,3,"slot3");
popupMenu.show();

 @Override
    public boolean onMenuItemClick(MenuItem item) 

        switch (item.getItemId()) 
            case R.id.slot1:
                SessionManager.selected_slot = item.getTitle().toString();
                Toast.makeText(this, "slot1 Clicked", Toast.LENGTH_SHORT).show();
                return true;
            case R.id.slot2:
                SessionManager.selected_slot = item.getTitle().toString();
                Toast.makeText(this, "slot2 Clicked", Toast.LENGTH_SHORT).show();
                return true;
            case R.id.slot3:
                SessionManager.selected_slot = item.getTitle().toString();
                Toast.makeText(this, "slot3 Clicked", Toast.LENGTH_SHORT).show();
                return true;
            default:
                return true;

这是一个更好的解释 你好。如何为图标执行此操作?【参考方案5】:

这是一个设置和处理 ID 的完整解决方案:

        this.findViewById(R.id.hamburger_menu).setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
            PopupMenu menu = new PopupMenu(getApplicationContext(), v);
            menu.getMenu().add(Menu.NONE, 1, 1, "Share");
            menu.getMenu().add(Menu.NONE, 2, 2, "Comment");
            menu.show();

            menu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() 
                @Override
                public boolean onMenuItemClick(MenuItem item) 

                    int i = item.getItemId();
                    if (i == 1) 
                        //handle share
                        return true;
                     else if (i == 2) 
                        //handle comment
                        return true;
                     else 
                        return false;
                    
                 

            );
         
     );

注意:以分享和评论为例,也可以为数字1,2添加常量,使代码更具可读性。

另外,我输入了Menu.NONE,因为我不关心对菜单项进行分组。如果您想让组设置组 id = 1、2 等...

【讨论】:

【参考方案6】:

@Voora Tarun 给出了一个很好的答案,我的答案基于它: 首先使用假的mune.xml 资源,我认为更好的方法是创建ids 文件:

ids.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="menuGroup" type="id"/>
    <item name="menu1" type="id"/>
    <item name="menu2" type="id"/>
    <item name="menu3" type="id"/>
</resources>

然后你可以这样做:

private void showPopup(final View anchor) 
        PopupMenu popupMenu = new PopupMenu(anchor.getContext(), anchor);
        popupMenu.getMenu().add(R.id.menuGroup, R.id.menu1, Menu.NONE, "slot1");
        popupMenu.getMenu().add(R.id.menuGroup, R.id.menu2, Menu.NONE,"slot2");
        popupMenu.getMenu().add(R.id.menuGroup, R.id.menu3, Menu.NONE,"slot3");
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() 
            @Override
            public boolean onMenuItemClick(MenuItem item) 
                Toast.makeText(anchor.getContext(), item.getTitle() + "clicked", Toast.LENGTH_SHORT).show();
                return true;
            
        );
        popupMenu.show();

【参考方案7】:

在java中

     private void getPopup(Activity sContext,TextView textView, ArrayList<String> arrayList) 
            final PopupMenu popupMenu = new PopupMenu(sContext, textView);
            for (int i = 0; i < arrayList.size(); i++) 
                popupMenu.getMenu().add(i, Menu.FIRST, i, arrayList.get(i));
            
            popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() 
                @Override
                public boolean onMenuItemClick(MenuItem item) 
                    textView.setText(item.getTitle());
                    return false;
                
            );
            popupMenu.show();
        

在 Kotlin 中

private fun getPopup(
    sContext: Activity,
    textView: TextView,
    arrayList: ArrayList<String>
) 
    val popupMenu = PopupMenu(sContext, textView)
    for (i in 0 until arrayList.size) 
        popupMenu.getMenu().add(i, Menu.FIRST, i, arrayList[i])
    
    popupMenu.setOnMenuItemClickListener(object : 
        PopupMenu.OnMenuItemClickListener 
        override fun onMenuItemClick(item: MenuItem): Boolean 
            textView.setText(item.getTitle())
            return false
        
    )
    popupMenu.show()

这是 android 中的动态弹出菜单。如果你想添加动态数据。例如: - 如果使用从 APIs 获取数据并在弹出窗口中显示数据,那么此代码非常有用。【参考方案8】:

如果您正在寻找带有回调的生成弹出项目,请使用此。

Java

public static void popupMenu(final Context context, View anchor, final LinkedHashMap<String,IPopupMenu> options)
        PopupMenu popupMenu = new PopupMenu(context, anchor);
        for(String key : options.keySet())
            popupMenu.getMenu().add(key);
        
        popupMenu.getMenuInflater().inflate(R.menu.popup_menu,popupMenu.getMenu());
        popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() 
            @Override
            public boolean onMenuItemClick(MenuItem menuItem) 

                options.get(menuItem.getTitle()).onClick();
                return true;
            
        );

        popupMenu.show();
    

public interface IPopupMenu
        void onClick();
    

XML

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

</menu>

示例

LinkedHashMap<String,IPopupMenu> menu_items = new LinkedHashMap<>();
menu_items.put("Item Name", new Utils.IPopupMenu() 
         @Override
         public void onClick() 
            //do your code
         
);
menu_items.put("My Item", new Utils.IPopupMenu() 
         @Override
         public void onClick() 
            //do code
         
);

//you can anchor the popup menu to whatever you like. i.e Button, TextView, View.
popupMenu(context,button,menu_items);

【参考方案9】:

来自字符串数组资源

值 > strings.xml

<string-array name="MainCategories">
        <item>Crop</item>
        <item>Animals</item>
        <item>Equipment</item>
        <item>Other</item>
    </string-array>

Java 代码:

    String []categories=getResources().getStringArray(R.array.MainCategories);
    PopupMenu popupMenu=new PopupMenu(MainActivity.this,sortExpenseBtn);

                for(String item: categories)
                    popupMenu.getMenu().add(item);

                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() 
                    @Override
                    public boolean onMenuItemClick(MenuItem item) 
                        String selected = item.getTitle();
                        return true;
                    
                );
                popupMenu.show();
