Cannot call View in Asynctask Android, java

Issue

I am trying to call the view from another class in my Asynctask class but it doesn't seem to be working.

Here is my AsyncTack

private class parseSite extends AsyncTask<String, Void, List<Integer>> {

    protected List<Integer> doInBackground(String... arg) {
     List<Integer> output = new ArrayList<Integer>();
        try {
            htmlHelper hh = new htmlHelper(new URL(arg[0]));
            output = hh.htmlHelper(arg[0]);
        } catch (Exception e) {
            System.out.println("Error");
        }
        return output;
    }

    protected void onPostExecute(List<Integer> exe) {

        graph salesView = new graph();
        View chartView = salesView.getView(this);
        chartView.setLayoutParams(new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.FILL_PARENT,
                LinearLayout.LayoutParams.FILL_PARENT, 1f));
        LinearLayout layout = (LinearLayout) findViewById(R.id.linearview);

        layout.addView(chartView, 0);

    }
}

And here is what the activity 'graph' looks like

public class graph {

public View getView(Context context) (...etc.)

I don't understand why it can't call the view.

Solution

Assuming you intended graph to extend Context in some way, such as by extending Activity, and that parseSite is defined inside graph, make the following change:

View chartView = salesView.getView(graph.this);

In the original code, this is referring to parseSite which does not extend Context (and does not refer to graph as you probably intend).

As a side note, in typical Java style classes should be named with an upper case letter, i.e. Graph not graph.
