Answer 1

This will not give error in Inflater and work properly:

    LayoutInflater layoutInflater = getLayoutInflater();


      View pview = layoutInflater.inflate(R.layout.popup_example,    (ViewGroup)findViewById(R.layout.main));
       PopupWindow pw = new PopupWindow(pview);
        pw.showAtLocation(v, Gravity.LEFT,0,0);
        pw.update(8,-70,150,270);

          //if onclick written here, it gives null pointer exception.
        ImageButton img=(ImageButton)pview.findViewById(R.id.home);
        img.setOnClickListener(new OnClickListener()
        {
            public void onClick(View v)
            {
                Intent.....
            }
    });

You have to find the button into the Popup view:

View pview = inflater.inflate(R.layout.popup_example,(ViewGroup)findViewById(R.layout.main));
PopupWindow pw = new PopupWindow(pview);
            pw.showAtLocation(v, Gravity.LEFT,0,0);
            pw.update(8,-70,150,270);

              //if onclick written here, it gives null pointer exception.
            ImageButton img=(ImageButton)pview.findViewById(R.id.home);
            img.setOnClickListener(new OnClickListener()
            {
                public void onClick(View v)
                {
                    Intent.....
                }
        });

In main activity button onClick you can use:

    popupWindow.getContentView().findViewById(R.id.buttonInPopup).setOnClickListener(new OnClickListener(...)
