I am calling menu xml like this

我正在像这样调用菜单 xml

     PopupMenu popup = new PopupMenu(getBaseContext(), v);
 popup.getMenuInflater().inflate(R.menu.menu,  popup.getMenu());
     popup.show();

But it does not show the icon.

Actually Context Menudoes not support the icons.

实际上上下文菜单不支持图标。

If you want context menu/pop up menu with icons Hereis the way.

如果你想要带有图标的上下文菜单/弹出菜单这是方法。

You can create popup menu with icon using the MenuBuilderand MenuPopupHelper.

您可以使用MenuBuilder和创建带有图标的弹出菜单MenuPopupHelper。

MenuBuilder menuBuilder =new MenuBuilder(this);
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.menu, menuBuilder);
MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, view);
optionsMenu.setForceShowIcon(true);

// Set Item Click Listener
menuBuilder.setCallback(new MenuBuilder.Callback() {
    @Override
    public boolean onMenuItemSelected(MenuBuilder menu, MenuItem item) {
        switch (item.getItemId()) {
            case R.id.opt1: // Handle option1 Click
                return true;
            case R.id.opt2: // Handle option2 Click
                return true;
            default:
                return false;
        }
    }

    @Override
    public void onMenuModeChange(MenuBuilder menu) {}
});

optionsMenu.show();

menu.xml

菜单文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/opt1"
        android:icon="@mipmap/ic_launcher"
        android:title="option 1" />
    <item
        android:id="@+id/opt2"
        android:icon="@mipmap/ic_launcher"
        android:title="option 2" />
</menu>

You can enable icons for popup menu by using Java reflection to call a hidden method as below:

您可以通过使用 Java 反射调用隐藏方法来启用弹出菜单的图标，如下所示：

public static void setForceShowIcon(PopupMenu popupMenu) {
    try {
        Field[] fields = popupMenu.getClass().getDeclaredFields();
        for (Field field : fields) {
            if ("mPopup".equals(field.getName())) {
                field.setAccessible(true);
                Object menuPopupHelper = field.get(popupMenu);
                Class<?> classPopupHelper = Class.forName(menuPopupHelper
                        .getClass().getName());
                Method setForceIcons = classPopupHelper.getMethod(
                        "setForceShowIcon", boolean.class);
                setForceIcons.invoke(menuPopupHelper, true);
                break;
            }
        }
    } catch (Throwable e) {
        e.printStackTrace();
    }
}

You could use reflection as described here: https://stackoverflow.com/a/18431605/4521603

您可以按照此处所述使用反射：https: //stackoverflow.com/a/18431605/4521603

Or if you use Xamarin / C#:

或者，如果您使用 Xamarin / C#：

add:

添加：

using Java.Lang.Reflect;

Then use this in your code:

然后在您的代码中使用它：

PopupMenu puMenu = new PopupMenu(Activity, v)

Field field = puMenu.Class.GetDeclaredField("mPopup");
field.Accessible = true;
Java.Lang.Object menuPopupHelper = field.Get(puMenu);
Method setForceIcons = menuPopupHelper.Class.GetDeclaredMethod("setForceShowIcon", Java.Lang.Boolean.Type);
setForceIcons.Invoke(menuPopupHelper, true);

puMenu.Inflate (Resource.Menu.your_actions);
puMenu.Show ();

before popupMenu.show(); use

在 popupMenu.show() 之前；用

try {

                    mFieldPopup.setAccessible(true);

You can implement this By the use of Reflection if u don`t familiar with it with the help of this awesome java advanced feature u can modify the runtime behavior of applications running in the JVM you can look at the object and perform its methods on runtime and in our case we need to modify popupMenu behavior at runtime instead of extend the core class and modify it ;) hope that help Try my method working like a charm

您可以通过使用反射来实现这一点，如果您不熟悉它，借助这个很棒的 Java 高级功能，您可以修改在 JVM 中运行的应用程序的运行时行为，您可以查看对象并在运行时执行其方法在我们的例子中，我们需要在运行时修改 popupMenu 行为，而不是扩展核心类并修改它；) 希望有所帮助 尝试我的方法像魅力一样工作

private void showPopupMenu(View view) {
    // inflate menu
    PopupMenu popup = new PopupMenu(mcontext, view);
    MenuInflater inflater = popup.getMenuInflater();
    inflater.inflate(R.menu.main, popup.getMenu());

    Object menuHelper;
    Class[] argTypes;
    try {
        Field fMenuHelper = PopupMenu.class.getDeclaredField("mPopup");
        fMenuHelper.setAccessible(true);
        menuHelper = fMenuHelper.get(popup);
        argTypes = new Class[]{boolean.class};
        menuHelper.getClass().getDeclaredMethod("setForceShowIcon", argTypes).invoke(menuHelper, true);
    } catch (Exception e) {

    }
    popup.show();




}

It's because when you use the showAsAction="never"attribute, the default overflow does not return your icon. You could create your own overflowlike this:

这是因为当您使用该showAsAction="never"属性时，默认溢出不会返回您的图标。您可以像这样创建自己的溢出：

<item android:title=""
        android:id="@+id/overflow"
        android:showAsAction="always"
        android:icon="@drawable/overflow_icon">
  <menu >    
    <item android:id="@+id/back"
          android:icon="@drawable/back1"
          android:title="Back" />

    <item android:id="@+id/My_Profile"
          android:icon="@drawable/myprofile"
          android:title="My Profile" />

    <item android:id="@+id/Job_Alert"
          android:icon="@drawable/jobalert4"
          android:title="Job Alert !" />

    <item android:id="@+id/saved_job"
          android:icon="@drawable/jobapplied"
          android:title="Saved Job"/>
    <item android:id="@+id/Logout"
          android:icon="@drawable/logout"
          android:title="Logout" /> 
  </menu>
</item>

if trying this code in any activity then replace getbBaseContext() with this i.e activity context

如果在任何活动中尝试此代码，则将 getbBaseContext() 替换为此活动上下文

PopupMenu popup = new PopupMenu(this, v);
