ACTIVITY

public class EpisodiActivity extends Activity {

private StartAppAd startAppAd = new StartAppAd(this);

public class ViewModel {
    private String url;
    private String name;

    public ViewModel(String url, String name) {
        this.url = url;
        this.name = name;
    }

    public String getUrl() {
        return this.url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String toString() {
        return this.name;
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // creazione fullscreen activity
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.episodi_activity);

    String[] episodi = getIntent().getStringArrayExtra("Product");
    String[] urls = getIntent().getStringArrayExtra("urls");

    ListView mylist = (ListView) findViewById(R.id.listView1);

    // And in this loop we create the ViewModel instances from
    // the name and url and add them all to a List
    List<ViewModel> models = new ArrayList<ViewModel>();
    for (int i = 0; i < episodi.length; i++) {
        String name = episodi[i];
        String url = "No value";
        if (i < urls.length) {
            url = urls[i];
        }
        ViewModel model = new ViewModel(url, name);
        models.add(model);
    }

    // Here we create the ArrayAdapter and assign it to the ListView
    // We pass the List of ViewModel instances into the ArrayAdapter
    final ArrayAdapter<ViewModel> adapter = new ArrayAdapter<ViewModel>(
            this, android.R.layout.simple_list_item_1, models);

    mylist.setAdapter(adapter);

    mylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> arg0, View v, int position,
                long id) {

            // Here we get the ViewModel at the given position
            ViewModel model = (ViewModel) arg0.getItemAtPosition(position);

            // And the url from the ViewModel
            String url = model.getUrl();

            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
        }
    });
}

@Override
public void onResume() {
    super.onResume();
    startAppAd.onResume();
    startAppAd.showAd();
}

@Override
public void onPause() {
    super.onPause();
    startAppAd.onPause();
}

}

A listView BaseAdapter first calls the method getCount() to retrieve the number of rows to show and then for each row it calls the getView(int position, View convertView, ViewGroup parent) method to create and return a View object for the given position.

The approach is to extend BaseAdapter and create your own custom Adapter, instead of using the default ArrayAdapter. Then you need to return an “Ad” View instead of your usual normal View when you want to display an ad. This means that you need to override getCount() to return more rows (for example if you have 10 rows, that means you need to return 11 = 10 actual content + 1 ad)

Then you need to decide in which position to create this View, I think you can do it by simply checking the position variable:

if (position == VALUE) {
   // Create and return Ad View 
} else {
   // Create and return a normal View 
}

Anyway, this whole thing is really tricky as things can go easily out of hand (positions mismatching with Views etc). StartApp should be able to control your listView adapter to do all this for you. My guess is that your adapter is not communicating properly with StartApp (maybe you are not initialising correctly?).

Try to dig into the documentation or find an example by them. If you can’t figure it out, there are other alternatives you can use such as Avocarrot, Namomedia, Inmobi, etc

I have used Avocarrot which has an open source example in github for inserting ads in listViews. You can run it and use it if it fits you: https://github.com/Avocarrot/android-demo-app
