      How to fetch data using Retrofit in Listview

      Asked 2017-Jun-24 at 18:35

      I am getting a nullPointException in my adapter class.

      I want to get contact from server containing name and email. my Contact class is

      public class Contact {
      
      @SerializedName("name")
      private String Name;
      
      @SerializedName("email")
      private String Email;
      
      
      public String getName() {
          return Name;
      }
      
      public String getEmail() {
          return Email;
      }
      

      }

      ApiClient CLass

      public class ApiClient {
      
      private static final String BASE_URL = "http://192.168.43.88/ContactApp/";
      public static Retrofit retrofit = null;
      
      public static Retrofit getApiClient (){
      
          if (retrofit == null){
              retrofit = new Retrofit.Builder().baseUrl(BASE_URL).addConverterFactory(GsonConverterFactory.create()).build();
          }
      
          return retrofit;
      }
      

      }

      this is an adapter class where I am getting null pointer exception in infalter

      public class RetrofitItemAdapter extends BaseAdapter{

      Context mContext;
      private List<Contact> mContact;
      RecyclerView.ViewHolder vh = null;
      
      //Constructor
      
      
      public RetrofitItemAdapter(List<Contact> mContact) {
      
          this.mContact = mContact;
      }
      
      
      public  class ViewHolder {
      
          public TextView tvName;
          public TextView tvEmail;
      
      
      }
      
      
      @Override
      public int getCount() {
          return mContact.size();
      }
      
      @Override
      public Object getItem(int position) {
          return mContact.get(position);
      }
      
      @Override
      public long getItemId(int position) {
          return position;
      }
      
      @Override
      public View getView(int position, View convertView, ViewGroup viewGroup) {
      
          View vi = convertView;
          ViewHolder holder;
      
          if (convertView == null) {
      
              LayoutInflater inflater;
              inflater = (LayoutInflater) mContext.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
      
              vi = inflater.inflate(R.layout.listview_retrofit_items, null);
      
              holder = new ViewHolder();
              holder.tvName  = (TextView) vi.findViewById(R.id.tv_ret_name);
              holder.tvEmail  = (TextView) vi.findViewById(R.id.tv_ret_email);
      
      
              vi.setTag(holder);
      
          } else
              holder = (ViewHolder) vi.getTag();
      
          // now set your text view here like
      
         // holder.tvName.setText("Bla Bla Bla");
      
          holder.tvName.setText(mContact.get(position).getName());
          holder.tvEmail.setText(mContact.get(position).getEmail());
      
      
          // return your view
          return vi;
      

      and finally my main class is

      public class RetrofitDemo extends AppCompatActivity {
      
      private ListView listView;
      private List<Contact> contacts;
      private RetrofitItemAdapter adapter;
      private ApiInterface apiInterface;
      
      
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_retrofit_demo);
      
          listView = (ListView)findViewById(R.id.lv_retrofitData);
      
          apiInterface = ApiClient.getApiClient().create(ApiInterface.class);
          Call<List<Contact>> call = apiInterface.getContacts();
      
          call.enqueue(new Callback<List<Contact>>() {
              @Override
              public void onResponse(Call<List<Contact>> call, Response<List<Contact>> response) {
      
                  contacts = response.body();
      
                  adapter = new RetrofitItemAdapter(contacts);
                  listView.setAdapter(adapter);
      
              }
      
              @Override
              public void onFailure(Call<List<Contact>> call, Throwable t) {
      
              }
          });
      
      }
      

      }

      ANSWER

      Answered 2017-Jun-24 at 18:35

      You are not setting the context object created in your Adaptor.

      You need to set that up by passing activity context along with the contacts you are passing onto the adaptor

      public RetrofitItemAdapter(List<Contact> mContact, Context context) {
         this.mContact = mContact;
         this.mContext = context;
      }
      

      And in activity

        adapter = new RetrofitItemAdapter(contacts, RetrofitDemo.this);
        listView.setAdapter(adapter);
