Question

我想显示PopupMenu在recycerview里面，但是当我单击menuButton应用时崩溃并发现问题时，我删除了从setOnClickListener调用的showPopupMenuMenu（）方法并替换为Toast，它工作正常
问题出在showPopupMenuMenu（）方法中的任何一个上，请帮助我解决此问题

holder.menuButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               try{
                   showPopupMenuMenu(holder,position);
               }catch (Exception e){
                   Log.e("showPopupMenuMenu",e.getMessage()+"");
               }
            }
        });

private void showPopupMenuMenu(MyViewHolder holder, final int position){
        //creating a popup menu
          PopupMenu popup = new PopupMenu(context, holder.menuButton);
        //inflating menu from xml resource
        popup.inflate(R.menu.recyclerview_option_menu);
        //adding click listener
       try{
           popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
               @Override
               public boolean onMenuItemClick(MenuItem item) {
                   switch (item.getItemId()) {
                       case R.id.edit_menu:
                           //handle menu1 click
                           if (context instanceof MyAddressActivity) {
                               ((MyAddressActivity) context).openEditAddressActivity(position, true);
                           } else if (context instanceof CheckoutLocationActivity) {
                               ((CheckoutLocationActivity) context).openEditAddressActivity();
                           }
                           break;
                       case R.id.delete_menu:
                           //handle menu2 click
                           if (context instanceof MyAddressActivity) {
                               ((MyAddressActivity) context).deleteAddressItem(position);
                           } else if (context instanceof CheckoutLocationActivity) {
                               ((CheckoutLocationActivity) context).mCheckoutLocationActivityPresenter.deleteAddressItem(position);
                           }
                           break;

                   }
                   return false;
               }
           });
       }catch (Exception e){
           Log.e("showPopupMenuMenu","setOnMenuItemClickListener  "+e.getMessage()+"");
       }
        //displaying the popup
        popup.show();
}

R.menu.recyclerview_option_menu

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

    <item
        android:id="@+id/edit_menu"
        android:title="@string/edit" />

    <item
        android:id="@+id/delete_menu"
        android:title="@string/delete" />

</menu>

Answer 1

如果您在Adapter中使用PopupMenu，请确保传递给Constructor的数据应该像

 AddressAdapter addressAdapter=new AddressAdapter(AddressList.this,addressModels);
                recyclerView.setAdapter(addressAdapter);

代替

 AddressAdapter addressAdapter=new AddressAdapter(getApplicationContext(),addressModels);
                recyclerView.setAdapter(addressAdapter);

注意：通过活动，而不是ApplicationContext（）

请尝试这个；

openPopUpMenu.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            PopupMenu popupMenu = new PopupMenu(activity, v);
            popupMenu.getMenuInflater().inflate(R.menu.pop_up_menu, popupMenu.getMenu());
            popupMenu.show();

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

                    if (menuItem.getTitle().equals("1. item title")) {
                        //do something
                    } else if (menuItem.getTitle().equals("2.item Title")) {
                        // do something
                    } 
                    return false;
                }
            });
        }
    });
