Question

I am trying to create a popup menu, but i am getting this error, saying "unknown member 'menu' of com.popup.trial.R

What should I do?

my xml file:

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

android:title="One"/>  
    <item

        @Override
        public void onClick(View v) {  
            PopupMenu popup = new PopupMenu(MainActivity.this, settings2);  
            popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());  
            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {  
                    public boolean onMenuItemClick(MenuItem item) {  
                        Toast.makeText(MainActivity.this,"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();  
                        return true;

        }  
    });

The R class is code-generated for you by the Android build tools when you build your project.

• Clean your project or Build your project

reference : Beginner Android why is "id" is "Unknown member" with R.id?
