在我的代碼中，我使用了一個可以使用Retrofit2和自定義recyclerview正常工作的Internet示例，但我決定在4.1.2版本的Android中使用此應用程序，因此recyclerview在此不起作用。那麼，是否有可能將自定義recyclerview更改爲自定義listview？在自定義視圖中改造2
Lista_productos.java
public class Lista_productos extends AppCompatActivity {
private RecyclerView recyclerView;
private RecyclerView.LayoutManager layoutManager;
private List<Elementos_fila_productos> elementos;
private RecyclerviewAdapter adapter;
private ApiInterface apiInterface;
static LayoutInflater layoutInflater;
static PopupWindow popupWindow;
static TextView nombre_seleccionado;
static FrameLayout frameLayout;
static String cantidad_deseada;
static char hola;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lista_productos);
recyclerView = (RecyclerView)findViewById(R.id.recyclerview_tablillas);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
if(getIntent().getExtras() != null){
String type = getIntent().getExtras().getString("type");
buscarInformacion(type);
}
}
public void buscarInformacion(String type){
apiInterface = ApiClient.getApiClient().create(ApiInterface.class);
Call<List<Elementos_fila_productos>> call = apiInterface.getElementosInfo(type);
call.enqueue(new Callback<List<Elementos_fila_productos>>() {
@Override
public void onResponse(Call<List<Elementos_fila_productos>> call, Response<List<Elementos_fila_productos>> response) {
elementos = response.body();
adapter = new RecyclerviewAdapter(elementos, Lista_productos.this);
recyclerView.setAdapter(adapter);
}
@Override
public void onFailure(Call<List<Elementos_fila_productos>> call, Throwable t) {
final AlertDialog.Builder builder = new AlertDialog.Builder(Lista_productos.this, R.style.Theme_AppCompat_Light_Dialog_Alert);
builder.setCancelable(true);
builder.setTitle("Error!");
builder.setMessage("mensaje");
builder.setIcon(R.drawable.ic_launcher);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
final AlertDialog dialog = builder.create();
dialog.show();
}
});
}
}
ListaComprasAdapter.java
public class ListaComprasAdapter extends BaseAdapter {
ArrayList<String> nombre;
ArrayList<String> cantidad;
ArrayList<String> precio;
ArrayList<String> total;
Context mContext;
//constructor
public ListaComprasAdapter(Context mContext, ArrayList<String> nombre, ArrayList<String> cantidad, ArrayList<String> precio, ArrayList<String> total) {
this.mContext = mContext;
this.nombre = nombre;
this.cantidad = cantidad;
this.precio = precio;
this.total = total;
}
public int getCount() {
return nombre.size();
}
public Object getItem(int arg0) {
return null;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View arg1, ViewGroup viewGroup) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.custom_lista_de_compras, viewGroup, false);
TextView Nombre = (TextView) row.findViewById(R.id.nombre_del_producto);
TextView Cantidad = (TextView) row.findViewById(R.id.cantidad);
TextView Precio = (TextView) row.findViewById(R.id.precio);
TextView Total = (TextView) row.findViewById(R.id.precio_total_producto);
Nombre.setText(nombre.get(position));
Cantidad.setText(cantidad.get(position));
Precio.setText(precio.get(position));
Total.setText(total.get(position));
return row;
}
}
Elementos_fila_productos.java：每一行的元素
public class Elementos_fila_productos {
@SerializedName("ID")
private String ID;
@SerializedName("Caracteristicas")
private String Caracteristicas;
@SerializedName("Precio")
private int Precio;
@SerializedName("Grosor")
private String Grosor;
@SerializedName("Disponibles")
private int Disponible;
@SerializedName("Imagen")
private String Imagen;
public String getGrosor() {
return Grosor;
}
public String getID() {
return ID;
}
public String getCaracteristicas() {
return Caracteristicas;
}
public int getPrecio() {
return Precio;
}
public int getDisponible() {
return Disponible;
}
public String getImagen() {
return Imagen;
}
}
ApiInterface.java
public interface ApiInterface {
@GET("tablillas2.php")
//revisar en el caso de que no funcione
Call<List<Elementos_fila_productos>> getElementosInfo(@Query("item_type") String item_type);
}
ApiClient.java
public class ApiClient {
public static final String Base_Url = "http://creadorjuancarloscfapptablilla.esy.es/appTablillas/";
public static Retrofit retrofit;
public static Retrofit getApiClient(){
if (retrofit==null){
retrofit = new Retrofit.Builder().baseUrl(Base_Url).addConverterFactory(GsonConverterFactory.create()).build();
}
return retrofit;
}
}
