Question

我有一个带有一个RatingBar和两个textview的ListView，当我在模拟器中运行应用程序时，它显示正确，但是当我尝试在我的Galaxy S3上运行它时，ratingbar不会出现在listview中，只显示文字视图。

任何人都知道我应该做些什么来纠正它？

ItemLista

    public class ItemLista {
private String nome;
private String comentario;
private float nota;

public ItemLista(String nome, String comentario, float nota) {
    super();
    this.nome = nome;
    this.comentario = comentario;
    this.nota = nota;
}

public String getNome() {
    return nome;
}
public void setNome(String nome) {
    this.nome = nome;
}
public String getComentario() {
    return comentario;
}
public void setComentario(String comentario) {
    this.comentario = comentario;
}
public float getNota() {
    return nota;
}
public void setNota(float nota) {
    this.nota = nota;
}   
}

ComentariosAdapter

    public class ComentariosAdapter extends ArrayAdapter<ItemLista> {
private final Context context;        
    private final ArrayList<ItemLista> itemsArrayList;

    public ComentariosAdapter(Context context, ArrayList<ItemLista> itemsArrayList) {

    super(context, R.layout.item_lista_comentarios, itemsArrayList);

    this.context = context;
    this.itemsArrayList = itemsArrayList;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

    // 1. Create inflater 
    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    // 2. Get rowView from inflater
    View rowView = inflater.inflate(R.layout.item_lista_comentarios, parent, false);

    // 3. Get the two text view from the rowView
    TextView nameView = (TextView) rowView.findViewById(R.id.txtUsuario);
    TextView comentarioView = (TextView) rowView.findViewById(R.id.txtComentario);
    RatingBar rankView = (RatingBar) rowView.findViewById(R.id.rankSmall);

    // 4. Set the text for textView 
    nameView.setText(itemsArrayList.get(position).getNome());
    comentarioView.setText(itemsArrayList.get(position).getComentario());
    rankView.setRating(itemsArrayList.get(position).getNota());
    rankView.setIsIndicator(true);

    // 5. return rowView
    return rowView;
    }
    }

TabDetalhes

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View V = inflater.inflate(R.layout.tab_detalhes, container, false);

    RatingBar rank = (RatingBar) V.findViewById(R.id.rank);
    rank.setRating((float) 3.5);
    rank.setIsIndicator(true);

    ComentariosAdapter adapter = new ComentariosAdapter(V.getContext(), dados());

    ListView lista = (ListView) V.findViewById(R.id.listaComentarios);

    lista.setAdapter(adapter);             
    return V;
    }

private ArrayList<ItemLista> dados(){
    ArrayList<ItemLista> items = new ArrayList<ItemLista>();
    items.add(new ItemLista("Lucas Freitas","Lugar legal, ambiente confortavel", 4.5f));
    items.add(new ItemLista("Eduardo Bonight","Cara, comi tanto que pediram pra eu sair D:", 3.5f));
    items.add(new ItemLista("Guilherme Garcia","O que eu to fazendo aqui ? o.O", 2.5f));
    items.add(new ItemLista("Caique Sampaio","Mano...eu tava upando ¬¬", 2.5f));

    return items;
    }
    }

Answer 1

RatingBar的大小是多少？你给它带有负边距-60dp和-5dp，所以我的猜测是你的RatingBar被移出可见区域。

根据this question猜猜。

RatingBar不会出现在ListView中
