onClickItem ListView ArrayAdapter personnalisé Android Studio

Bon après-midi,

J'essaie de toucher un listItem de ma listView et de détecter le toucher (et d'obtenir quel listItem a été touché) car après cela, je vais afficher une nouvelle activité avec les informations de la publication.

Mais j'ai des problèmes parce que je ne sais pas comment le faire et aussi j'ai essayé beaucoup de tutoriels et de codes différents et cela ne fonctionne jamais dans mon cas, et c'est pourquoi je vais publier mon code complet parce que je ' m plus d'options pour le moment.

C'est mon code:

public class Blog extends AppCompatActivity {

// URL
String url = "https://www.mywebsite.com/";

// Key JSON
String keyJSON = "posts";

// Construct the data source
ArrayList<Blog> array = new ArrayList<Blog>();

// Background color action bar
String actionBarBackgroundColor = "#00b7bb";

// Title action bar
String actionBarTitle = "Blog";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.blog);

    // Action Bar
    setupActionBar(actionBarBackgroundColor, actionBarTitle);

    // Create the adapter to convert the array to views
    final BlogAdapter adapter = new BlogAdapter(this, array);

    // Load posts
    initBlog(adapter);
}

// Action Bar
public void setupActionBar(String color, String titulo) {
    // Create Action bar
    ActionBar mActionBar = getSupportActionBar();

    // Display title
    getSupportActionBar().setTitle(titulo);

    // Action bar background
    mActionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor(color)));

    // Show back arrow
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
}

// Get the information and display it in the ListView
private void initBlog(final BlogAdapter adapter) {

    // List View
    ListView listView = (ListView) findViewById(R.id.listv);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
            Log.d("Click","Click");
        }
    });

    // Attach the adapter to a ListView
    listView.setAdapter(adapter);

    JsonObjectRequest jsObjRequest = new JsonObjectRequest (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

        @Override
        public void onResponse(JSONObject response) {
            try{
                JSONObject jsonResponse = new JSONObject(response.toString());

                //Show result
                //Log.d("Result", jsonResponse.toString());

                JSONArray jsonMainNode = jsonResponse.optJSONArray(keyJSON);

                // Create products
                for(int i = 0; i<jsonMainNode.length();i++){
                    JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
                    String titulo = jsonChildNode.getString("title");
                    String fecha = jsonChildNode.getString("fecha");
                    String imagen = jsonChildNode.getString("imagen");
                    String introtext = jsonChildNode.getString("introtext");
                    String fulltext = jsonChildNode.getString("fulltext");

                    Blog newPost = new Blog(titulo, fecha, imagen, introtext, fulltext);

                    adapter.add(newPost);
                }
            }
            catch(JSONException e) {
                Toast.makeText(getApplicationContext(), "Error" + e.toString(), Toast.LENGTH_SHORT).show();
            }
        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            Log.d("Error", error.toString());
        }
    });

    // Access the RequestQueue through your singleton class.
    MySingleton.getInstance(this).addToRequestQueue(jsObjRequest);
}

// Back arrow action
public boolean onOptionsItemSelected(MenuItem item){
    Intent myIntent = new Intent(getApplicationContext(), MenuPrincipal.class);
    startActivityForResult(myIntent, 0);
    return true;
}
}
