        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            // TODO Auto-generated method stub


            Bundle programNum = getIntent().getExtras();
            final String progNum = programNum.getString("ProgNum");
            final String dayNum = programNum.getString("DayNum");

            final List<TouringPrograms> startTime = datasource.getTouringProgramsStartTime(progNum, dayNum);
            final List<TouringPrograms> endTime = datasource.getTouringProgramsEndTime(progNum, dayNum);

            Intent intent = new Intent(this, ProgramsList2.class);
            PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
            String body = (String) ((TextView)parent.getChildAt(position)).getText();
            String title = "Egypt On The Go";
            String time = body + "\n start at:" + startTime.get(position)+ "\n end at:" + endTime.get(position);
            Notification n = new Notification(R.drawable.egypt, time, System.currentTimeMillis());
            n.setLatestEventInfo(this, title, time, pi);
            n.defaults = Notification.DEFAULT_ALL;
            nm.notify(uniqueID, n);
            //String time1 = "" + System.currentTimeMillis();
            //Toast.makeText(this, time1, Toast.LENGTH_SHORT).show();
            //finish();

        }});

2.PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);

3.n.setLatestEventInfo(this, title, time, pi);

any help please?

Answer 1

Error 1

Intent intent = new Intent(this, ProgramsList2.class);

this is an item of type OnItemClickListener. You should pass it by declaring final Context intentContext = (Context) this; before calling setOnItemClickListener. Then, use:

Intent intent = new Intent(intentContext, ProgramsList2.class);

Always remember to keep track of your Context items; they’re important for things like this (Intents, resources, assets, etc.).

Error 2

PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);

Exactly the same problem as above. this is not of type Context. Use the same fix as above.

Error 3

n.setLatestEventInfo(this, title, time, pi);

And here, same issue as the above two. You’re using this when you should be using a Context. Same fix as the above two.

Summary

Keep track of your thiss when using anonymous classes. And for the future, posting the compile errors (the line of code as well as the text of the error itself) is incredibly helpful to those who will provide answers.
