Je crée une vue recycleur pour afficher les données, ensuite je veux passer la position des données à l'autre activité, mais quand j'utilise le loge pour vérifier si la position est réussie ou non ne trouve pas la position dans logcat.Transmettre les données de l'activité avec modification
Dans MainActivity j'ajouter la liste statique pour le modèle de recettes et je créer méthode pour retourner cette liste:
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private ProgressBar progressBar;
private LinearLayoutManager mLayoutManager;
private ArrayList<Model> list;
private RecyclerViewAdapter adapter;
private static List<Recipe>mListrecipe;
String url = "https://d17h27t6h515a5.cloudfront.net/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
progressBar = (ProgressBar) findViewById(R.id.progressbar);
mLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(mLayoutManager);
/// create a list--
list = new ArrayList<>();
/// get the list from json file
getRetrofitArray();
adapter = new RecyclerViewAdapter(list, MainActivity.this);
// set adapter to recyclerview
recyclerView.setAdapter(adapter);
}
public void getRetrofitArray(){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
RetrofitArrayAPI service = retrofit.create(RetrofitArrayAPI.class);
Call<List<Recipe>> call = service.getRecipeDetails();
call.enqueue(new Callback<List<Recipe>>() {
@Override
public void onResponse(Call<List<Recipe>> call, Response<List<Recipe>> response) {
Log.e("main ", " retrofit response "+ response.body().toString());
mListrecipe=response.body();
for (int i=0; i<response.body().size();i++){
Log.e("main ", " name "+ response.body().get(i).getName() + " serving "+
response.body().get(i).getServings());
list.add(new Model(Model.IMAGE_TYPE,response.body(), response.body().get(i).getName() ,
" Serving " +response.body().get(i).getServings()) );
}
adapter.notifyDataSetChanged();
}
@Override
public void onFailure(Call<List<Recipe>> call, Throwable t) {
Log.e("main ", " retrofit error "+ t.toString());
}
});
}
public static List<Recipe>getList(){
return mListrecipe;
}
}
ajouter putExtra avec une valeur clé pour passer la position
public class RecyclerViewAdapter extends RecyclerView.Adapter {
private ArrayList<Model> dataset;
private Context mContext;
public RecyclerViewAdapter(ArrayList<Model> mlist, Context context) {
this.dataset = mlist;
this.mContext = context;
}
public static class ImageTypeViewHolder extends RecyclerView.ViewHolder{
ImageView imageView;
TextView title, subtitle;
public ImageTypeViewHolder(View itemView) {
super(itemView);
this.title = (TextView) itemView.findViewById(R.id.title);
this.subtitle = (TextView) itemView.findViewById(R.id.subtitle);
this.imageView=(ImageView)itemView.findViewById(R.id.imageview);
}
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.itemlist, parent, false);
return new ImageTypeViewHolder(view) ;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
Model object = dataset.get(position);
((ImageTypeViewHolder) holder).title.setText(object.title);
((ImageTypeViewHolder) holder).subtitle.setText(object.subtitle);
/// dataset.get(position)
((ImageTypeViewHolder) holder).title.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent=new Intent(mContext,SelectReceipe.class);
intent.putExtra("itempostion",position);
mContext.startActivity(intent);
}
});
((ImageTypeViewHolder) holder).subtitle.setOnClickListener(new View.OnClickListener() {
@Override

}
});
}
@Override

cette est 2 activité je passe la position, mais je ne peux pas trouver la valeur dans logcat
