Overriding Getview Of Arrayadapter To Fill 3 Textviews

From my Activity, I am calling my MovieTask that extendsAsyncTask. I get Json response from the server which I have successfully parsed inside the doInBackground method of MovieTas

Solution 1:

When you setAdapter() on an AdapterView for example ListView, getView() is called internally and the views returned from the same are populated in the AdapterView.

You might want to read and learn about how AdapterViews and Adapters work. Go ahead and read some docs here:

• Using an ArrayAdapter with ListView
• Custom ArrayAdapter for a ListView
• Grid View and Adapter

What you need to do is:

• Create a model for your data like:

  publicclassMovie {
      publiclong id;
      public String date;
      public String title;
      publicdouble vote;
  
      publicMovie(long id, String date, String title, double vote){
          this.id = id;
          this.date = date;
          this.title = title;
          this.vote = vote;
      }
  }
  

• Create a layout to show movie details like:

  <?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><TextViewandroid:id="@+id/lbl_date"android:layout_width="wrap_content"android:layout_height="wrap_content" /><TextViewandroid:id="@+id/lbl_title"android:layout_width="wrap_content"android:layout_height="wrap_content" /><TextViewandroid:id="@+id/lbl_vote"android:layout_width="wrap_content"android:layout_height="wrap_content" /></LinearLayout>

• Change your adapter to handle Movies rather than Strings like:

  publicclassMovieListAdapterextendsArrayAdapter<Movie > {
      publicMovieListAdapter(Context context, List<Movie> objects) {
          super(context, 0, objects);
      }
  
      @Overridepublic View getView(int position, View convertView, ViewGroup parent) {
          if (convertView == null) {
              convertView = LayoutInflater.from(getContext()).inflate(R.layout.movie_item, parent, false);
          }
  
          ((TextView) convertView.findViewById(R.id.lbl_date))
                  .setText(getItem(position).date);
  
          ((TextView) convertView.findViewById(R.id.lbl_title))
                  .setText(getItem(position).title);
  
          ((TextView) convertView.findViewById(R.id.lbl_vote))
                  .setText(String.valueOf(getItem(position).vote));
  
          return convertView;
      }
  }
  

• Finally set the adapter after your for loop like:

  privatevoidgetMovieDataFromJson(String JsonString)throws JSONException {
      JSONObjectjsonObject=newJSONObject(JsonString);
      JSONArrayresults= jsonObject.getJSONArray("results");
  
      ArrayList<Movie> movies = newArrayList<>();
  
      for (int i=0; i<results.length(); i++){
          Stringtitle= results.getJSONObject(i).getString("original_title");
          Stringdate= results.getJSONObject(i).getString("release_date");
          longid= results.getJSONObject(i).getLong("id");
          doublevote= results.getJSONObject(i).getDouble("vote_average");
  
          movies.add(newMovie(id, date, title, vote));
      }
  
      myMoviesListView.setAdapter(newMovieListAdapter(MainActivity.this, movies));
  }
