android PopupMenu中的可检查项可能无法正常工作

Question

I have a problem in my app when I'm using popup menu whith checkable item.

I wanted to implement multi check item in my popup menu but when clicking one item the menu disappear although I have set the checkable behavior to all

this is the menu layout

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

<group android:checkableBehavior="all">
    <item android:id ="@+id/sun"
        android:checkable="true"
        android:title="@string/sun"/>
    <item android:id ="@+id/Mon"
        android:title="@string/Mon"/>
    <item android:id ="@+id/Tus"
        android:title="@string/Tus"/>
    <item android:id ="@+id/Wed"
        android:title="@string/wed"/>
    <item android:id ="@+id/Thu"
        android:title="@string/Thu"/>
    <item android:id ="@+id/fri"
        android:title="@string/fri"/>
    <item android:id ="@+id/Sat"
        android:title="@string/Sat"/>



</group>

and this is the switch statement where I guess that the error is here but I cant find it

                    PopupMenu popupMenu = new PopupMenu(getBaseContext(), ch_specificDay);
                    MenuInflater inflater = popupMenu.getMenuInflater();
                    inflater.inflate(R.menu.weekdays, popupMenu.getMenu());

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


                         switch (item.getItemId()) {
                             case R.id.sun:

Answer 1

Here is the solution for you.

On click of menu Item call a method

keepMenuOpen(item);

This keepMenuOpen is defined like this.

private void keepMenuOpen(MenuItem item) {

        item.setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
        item.setActionView(new View(HomeActivity.this));
        item.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                return false;
            }

            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                return false;
            }
        });
    }

终于，我找到了解决方案（有人帮助我在facebook上）我只是将return true更改为false
