Java class with parameter

[Wavix John]

Hi!

I have this DownloadJSON class initialized on onCreate with

new DownloadJSON().execute();

@Override
protected Void doInBackground(Void... params) {
    arraylist = new ArrayList<HashMap<String, String>>();
    jsonobject = JSONfunctions.getJSONfromURL("http://www.domain.com/json2.txt");
    try {
        jsonarray = jsonobject.getJSONArray("worldpopulation");

        for (int i = 0; i < jsonarray.length(); i++) {
            HashMap<String, String> map = new HashMap<String, String>();
            jsonobject = jsonarray.getJSONObject(i);
            map.put("rank", jsonobject.getString("rank"));
            arraylist.add(map);
        }
    } catch (JSONException e) {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
    }
    return null;Below, depending where users clicks, I want to change jsonobject = JSONfunctions.getJSONfromURL("http://www.domain.com/json1.txt");

Something like this:
}

@Override
    protected void onPostExecute(Void args) {
        listview = (ListView) findViewById(R.id.listview);
        adapter = new ListViewAdapter(MainActivity.this, arraylist);
        listview.setAdapter(adapter);
    }
}

Below, depending where users clicks, I want to change

jsonobject = JSONfunctions.getJSONfromURL("http://www.domain.com/json1.txt");

Something like this:

public boolean onNavigationItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.itemone) {
        new DownloadJSON().execute("http://www.domain.com/json2.txt");
    }
    else if (id == R.id.itemtwo) {
        new DownloadJSON().execute("http://www.domain.com/json3.txt");
    }

    return true;
}

How I can obtain this? I can't figure out how to do it.

Thanks!

        new DownloadJSON().execute("http://www.domain.com/json2.txt");

The value which you passed in the execute can be obtained like this

protected Void doInBackground(String... params) {
    String url = params[0];
    arraylist = new ArrayList<HashMap<String, String>>();
    jsonobject = JSONfunctions.getJSONfromURL(url);
    ...
}
