PopupMenu with icons [duplicate]

问题


Of course we are dealing here with SDK 11 and above.

I intend to do something similar to this: \"enter

Next to each item in that PopupMenu, I would like to place an icon.

I created an XML file and placed it in /menu:

<menu xmlns:android=\"http://schemas.android.com/apk/res/android\" >

    <item
        android:id=\"@+id/action_one\"
        android:title=\"Sync\"
        android:icon=\"@android:drawable/ic_popup_sync\"
        />

    <item
        android:id=\"@+id/action_two\"
        android:title=\"About\"
        android:icon=\"@android:drawable/ic_dialog_info\"
        />
</menu>

As you noticed, in the xml file I am defining the icons I want, however, when the popup menu shows, it is showing them without the icons. What should I do to make those 2 icons appear?

I would implement it otherwise:

Create an PopUpWindow layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/llSortChangePopup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/sort_popup_background"
android:orientation="vertical" >

<TextView
    android:id="@+id/tvDistance"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/distance"
    android:layout_weight="1.0"
    android:layout_marginLeft="20dp"
    android:paddingTop="5dp"
    android:gravity="center_vertical"
    android:textColor="@color/my_darker_gray" />

<ImageView
    android:layout_marginLeft="11dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/sort_popup_devider" 
    android:contentDescription="@drawable/sort_popup_devider"/>

<TextView
    android:id="@+id/tvPriority"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/priority"
    android:layout_weight="1.0"
    android:layout_marginLeft="20dp"
    android:gravity="center_vertical"
    android:clickable="true"
    android:onClick="popupSortOnClick"
    android:textColor="@color/my_black" />


<ImageView
    android:layout_marginLeft="11dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/sort_popup_devider" 
    android:contentDescription="@drawable/sort_popup_devider"/>

<TextView
    android:id="@+id/tvTime"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/time"
    android:layout_weight="1.0"
    android:layout_marginLeft="20dp"
    android:gravity="center_vertical"
    android:clickable="true"
    android:onClick="popupSortOnClick"
    android:textColor="@color/my_black" />

<ImageView
    android:layout_marginLeft="11dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/sort_popup_devider" 
    android:contentDescription="@drawable/sort_popup_devider"/>

<TextView
    android:id="@+id/tvStatus"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/status"
    android:layout_weight="1.0"
    android:layout_marginLeft="20dp"
    android:gravity="center_vertical"
    android:textColor="@color/my_black" 
    android:clickable="true"
    android:onClick="popupSortOnClick"
    android:paddingBottom="10dp"/>

 </LinearLayout>

and then create the PopUpWindow in your Activity: 

    // The method that displays the popup.
private void showStatusPopup(final Activity context, Point p) {

   // Inflate the popup_layout.xml
   LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.llStatusChangePopup);
   LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   View layout = layoutInflater.inflate(R.layout.status_popup_layout, null);

   // Creating the PopupWindow
   changeStatusPopUp = new PopupWindow(context);
   changeStatusPopUp.setContentView(layout);
   changeStatusPopUp.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
   changeStatusPopUp.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
   changeStatusPopUp.setFocusable(true);

   // Some offset to align the popup a bit to the left, and a bit down, relative to button's position.
   int OFFSET_X = -20;
   int OFFSET_Y = 50;

   //Clear the default translucent background
   changeStatusPopUp.setBackgroundDrawable(new BitmapDrawable());

   // Displaying the popup at the specified location, + offsets.
   changeStatusPopUp.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
}

finally pop it it up onClick of a button or anything else:

 imTaskStatusButton.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) 
            {
                 int[] location = new int[2];
                 currentRowId = position;
                 currentRow = v;    
                 // Get the x, y location and store it in the location[] array
                 // location[0] = x, location[1] = y.
                 v.getLocationOnScreen(location);

                 //Initialize the Point with x, and y positions
                 point = new Point();
                 point.x = location[0];
                 point.y = location[1];
                 showStatusPopup(TasksListActivity.this, point);
            }
        });

Good example for PopUpWindow:

This way works if you're using AppCompat v7. It's a little hacky but significantly better than using reflection and lets you still use the core Android PopupMenu: 

PopupMenu menu = new PopupMenu(getContext(), overflowImageView);
menu.inflate(R.menu.popup);
menu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { ... });

MenuPopupHelper menuHelper = new MenuPopupHelper(getContext(), (MenuBuilder) menu.getMenu(), overflowImageView);
menuHelper.setForceShowIcon(true);
menuHelper.show();

res/menu/popup.xml 

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

    <item android:id="@+id/menu_share_location"
        android:title="@string/share_location"
        android:icon="@drawable/ic_share_black_24dp"/>

</menu>


This results in the popup menu using the icon that is defined in your menu resource file:




回答3:


Android popup menu has a hidden method to show menu icon. Use Java reflection to enable it as below code snippet.

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();
    }
}

Popup menu with icon using MenuBuilder and 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) {}
    });


    // Display the menu
    optionsMenu.show();

menu.xml

<?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>

The MenuPopupHelper class in AppCompat has the @hide annotation. If that's a concern, or if you can't use AppCompat for whatever reason, there's another solution using a Spannable in the MenuItem title which contains both the icon and the title text.

The main steps are:

  • inflate your PopupMenu with a menu xml file
  • if any of the items have an icon, then do this for all of the items:
    • if the item doesn't have an icon, create a transparent icon. This ensures items without icons will be aligned with items with icons
    • create a SpannableStringBuilder containing the icon and title
    • set the menu item's title to the SpannableStringBuilder
    • set the menu item's icon to null, "just in case"

Pros: No reflection. Doesn't use any hidden apis. Can work with the framework PopupMenu.

Cons: More code. If you have a submenu without an icon, it will have unwanted left padding on a small screen.

Details:

First, define a size for the icon in a dimens.xml file:

<dimen name="menu_item_icon_size">24dp</dimen>

Then, some methods to move the icons defined in xml into the titles:

/**
 * Moves icons from the PopupMenu's MenuItems' icon fields into the menu title as a Spannable with the icon and title text.
 */
public static void insertMenuItemIcons(Context context, PopupMenu popupMenu) {
    Menu menu = popupMenu.getMenu();
    if (hasIcon(menu)) {
        for (int i = 0; i < menu.size(); i++) {
            insertMenuItemIcon(context, menu.getItem(i));
        }
    }
}

/**
 * @return true if the menu has at least one MenuItem with an icon.
 */
private static boolean hasIcon(Menu menu) {
    for (int i = 0; i < menu.size(); i++) {
        if (menu.getItem(i).getIcon() != null) return true;
    }
    return false;
}

/**
 * Converts the given MenuItem's title into a Spannable containing both its icon and title.
 */
private static void insertMenuItemIcon(Context context, MenuItem menuItem) {
    Drawable icon = menuItem.getIcon();

    // If there's no icon, we insert a transparent one to keep the title aligned with the items
    // which do have icons.
    if (icon == null) icon = new ColorDrawable(Color.TRANSPARENT);

    int iconSize = context.getResources().getDimensionPixelSize(R.dimen.menu_item_icon_size);
    icon.setBounds(0, 0, iconSize, iconSize);
    ImageSpan imageSpan = new ImageSpan(icon);

    // Add a space placeholder for the icon, before the title.
    SpannableStringBuilder ssb = new SpannableStringBuilder("       " + menuItem.getTitle());

    // Replace the space placeholder with the icon.
    ssb.setSpan(imageSpan, 1, 2, 0);
    menuItem.setTitle(ssb);
    // Set the icon to null just in case, on some weird devices, they've customized Android to display
    // the icon in the menu... we don't want two icons to appear.
    menuItem.setIcon(null);
}

Finally, create your PopupMenu and use the above methods before showing it:

PopupMenu popupMenu = new PopupMenu(view.getContext(), view);
popupMenu.inflate(R.menu.popup_menu);
insertMenuItemIcons(textView.getContext(), popupMenu);
popupMenu.show();

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 at 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 

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();




}



回答7:


Read the PopupMenu source code. We can show icon by the below code:

Field field = popupMenu.getClass().getDeclaredField("mPopup");
field.setAccessible(true);
MenuPopupHelper menuPopupHelper = (MenuPopupHelper) field.get(popupMenu);
menuPopupHelper.setForceShowIcon(true);

But MenuPopupHelper.java is in android internal package. So we should use Reflection:

    PopupMenu popupMenu = new PopupMenu(this, anchor);
    popupMenu.getMenuInflater().inflate(R.menu.process, popupMenu.getMenu());

    try {
        Field field = popupMenu.getClass().getDeclaredField("mPopup");
        field.setAccessible(true);
        Object menuPopupHelper = field.get(popupMenu);
        Class<?> cls = Class.forName("com.android.internal.view.menu.MenuPopupHelper");
        Method method = cls.getDeclaredMethod("setForceShowIcon", new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(menuPopupHelper, new Object[]{true});
    } catch (Exception e) {
        e.printStackTrace();
    }

    popupMenu.show();

I solved my issue the simplest possible way ever, never expected such a simplicity:

In main.xml:

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

<item
    android:id="@+id/action_more"
    android:icon="@android:drawable/ic_menu_more"
    android:orderInCategory="1"
    android:showAsAction="always"
    android:title="More">
    <menu>
        <item
            android:id="@+id/action_one"
            android:icon="@android:drawable/ic_popup_sync"
            android:title="Sync"/>
        <item
            android:id="@+id/action_two"
            android:icon="@android:drawable/ic_dialog_info"
            android:title="About"/>
    </menu>
</item>

in MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

That was a trick by using a submenu

        return true;

I was trying @Stephen Kidson's answer and @david.schereiber's suggestion, and I realized that there is no such method setOnMenuItemClickListener in MenuBuilder. Messed around with the v7's source code a little bit and I found this solution:

        MenuBuilder menuBuilder = new MenuBuilder(mContext);
        new SupportMenuInflater(mContext).inflate(R.menu.my_menu, menuBuilder);
        menuBuilder.setCallback(new MenuBuilder.Callback() {
            @Override
            public boolean onMenuItemSelected(MenuBuilder menu, MenuItem menuItem) {
                // your "setOnMenuItemClickListener" code goes here
                switch (menuItem.getItemId()) {
                    case R.id.menu_id1:
                        // do something 1
                        return true;

                    case R.id.menu_id2:
                        // do something 2
                        return true;
                }
                return false;
            }

            @Override
            public void onMenuModeChange(MenuBuilder menu) {
            }
        });
        MenuPopupHelper menuHelper = new MenuPopupHelper(mContext, menuBuilder, v);
        menuHelper.setForceShowIcon(true); // show icons!!!!!!!!
        menuHelper.show();
