我有一个活动FilmActivity.java

    setContentView(R.layout.activity_film);

    MobileAds.initialize(this, getString(R.string.admob_app_id));
    AdRequest adIRequest = new AdRequest.Builder().build();

    // Prepare the Interstitial Ad Activity
    interstitial = new InterstitialAd(FilmActivity.this);

    final List<LinkedHashMap<String, String>> listItems = new ArrayList<>();
    SimpleAdapter adapter = new SimpleAdapter(this, listItems, R.layout.biolist,
            new String[]{"First Line", "Second Line"},
            new int[]{R.id.text1, R.id.text2});


    Iterator it = filmNames.entrySet().iterator();
    while (it.hasNext()) {
        LinkedHashMap<String, String> resultsMap = new LinkedHashMap<>();
        Map.Entry pair = (Map.Entry) it.next();
        resultsMap.put("First Line", pair.getKey().toString());
        resultsMap.put("Second Line", pair.getValue().toString());
        listItems.add(resultsMap);
    }

    resultsListView.setAdapter(adapter);

    resultsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

            LinkedHashMap<String, String> selectItem = listItems.get(position);
            String firstLine = selectItem.get("First Line");
            String secondLine = selectItem.get("Second Line");

            Intent intent = new Intent(FilmActivity.this, FilmDetailActivity.class);

            intent.putExtra("firstLine", firstLine);
            intent.putExtra("secondLine", secondLine);
            startActivity(intent);
        }
    });

}
public void displayInterstitial()
{
    // If Interstitial Ads are loaded then show else show nothing.
    if (interstitial.isLoaded()) {
        interstitial.show();
    }
}

}

我需要将值1分配给第一项，将2分配给第二项，将3分配给第三项，依此类推，然后将其传递给下一个活动（FIlmDetailActivity.java）。在下一个活动中，如果该值是1，我将显示图像1，如果值是2，则显示图像2，依此类推。给我完整的代码，因为我是android开发的新手。
