Question

我有一个铃声列表视图，主片段中的每一行都有一个书签图标。我还有另一个片段来显示里面最受欢迎的铃声。当我点击一个项目将其标记为收藏时它将正常工作，所选项目将成功添加到我最喜欢的列表片段。但问题是这不适用于铃声（songID）。例如，如果我选择项目＃2，它将在喜欢的片段中添加项目＃2，但它将播放第一个原始音频。

在主要片段

中

private final int[] songID = { R.raw.aaa, R.raw.bbb, R.raw.ccc}; 

private List<ProductLight> songList = new ArrayList<ProductLight>();

    ProductLight product1 = new ProductLight(1,"Song Title 1");
    ProductLight product2 = new ProductLight(2,"Song Title 2");
    ProductLight product3 = new ProductLight(3,"Song Title 3");

    songList = new ArrayList<ProductLight>();
    songList.add(product1);
    songList.add(product2);
    songList.add(product3);

添加到最喜欢的逻辑：

    @Override
public boolean favOnClick(int position , View v) {
    ProductLight product = songList.get(position);
    ImageView button = (ImageView) v.findViewById(R.id.favImageHive);
    String tag = button.getTag().toString();
    if (tag.equalsIgnoreCase("grey")) {
        sharedPreference.addFavorite(product);
        snackS("Added to Favorites");
        button.setTag("red");
        button.setImageResource(R.mipmap.bookmarked);
    } else {
        sharedPreference.removeFavorite(product);
        button.setTag("grey");
        button.setImageResource(R.mipmap.bookmark_border);
        snackS("Removed from Favorites");
    }

    return true;
}

在我的最喜欢的片段

中

private final int[] songID = { R.raw.aaa, R.raw.bbb, R.raw.ccc}; 

private List<ProductLight> songList = new ArrayList<ProductLight>();

songList = sharedPreference.getFavorites();

共享偏好设置

public class SharedPreference_light {

public static final String PREFS_NAME = "Light_Products";
public static final String FAVORITES = "Favorite_Tones_Light";

SharedPreferences settings;
SharedPreferences.Editor editor;
Gson gson = new Gson();

public SharedPreference_light(Context context) {
    settings = context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
    editor = settings.edit();
}

// This four methods are used for maintaining favorites.
public void saveFavorites(List<ProductLight> favorites) {
    String jsonFavorites = gson.toJson(favorites);
    editor.putString(FAVORITES, jsonFavorites);
    editor.apply();
}

public void addFavorite(ProductLight product) {
    List <ProductLight> favorites = getFavorites();
    if (favorites == null)
        favorites = new ArrayList<ProductLight>();
    favorites.add(product);
    saveFavorites(favorites);
    Log.w("addPrefLog", favorites.toString());
}

public void removeFavorite(ProductLight product) {
    ArrayList <ProductLight> favorites = getFavorites();
    if (favorites != null) {
        favorites.remove(product);
        saveFavorites(favorites);
    }
}

public ArrayList <ProductLight> getFavorites() {
    List<ProductLight> favorites;
    if (settings.contains(FAVORITES)) {
        String jsonFavorites = settings.getString(FAVORITES, null);
        ProductLight[] favoriteItems = gson.fromJson(jsonFavorites, ProductLight[].class);
        favorites = Arrays.asList(favoriteItems);
        favorites = new ArrayList <ProductLight> (favorites);
    } else
        return null;

    return (ArrayList <ProductLight> ) favorites;
    }
 }

模型类

public class ProductLight {

private String title;
private int id;
private ArrayList<String> genre;

public ProductLight(int id,String name,ArrayList<String> genre){
    this.title = name;
    this.id = id;
    this.genre = genre;
}

public boolean paused = true;

private String Tag;
public String getTag() {
    return Tag;
}
public void setTag(String tag) {
    Tag = tag;
}

private int favId;
public int getFavId() {
    return favId;}
public void setFavId(int favId) {
    this.favId = favId;
}

public String getTitle() {
    return title;
}
public void setTitle(String name) {
    this.title = name;
}
public int getYear() {
    return id;
}
public ArrayList<String> getGenre() {
    return genre;
}
public void setGenre(ArrayList<String> genre) {
    this.genre = genre;
}



@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + id;
    return result;
}

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    ProductLight other = (ProductLight) obj;
    if (id != other.id)
        return false;
    return true;
}

@Override
public String toString() {
    return "Product [id=" + id + ", name=" + title + ", genre="
            + genre + "]";
    }
}

我不知道如何做对，请问你能帮助我吗？

如你所说：

当我点击一个项目将其标记为收藏时，它将正常工作，所选项目将成功添加到我最喜欢的列表片段。

然后尝试将另一个参数作为音频资源添加到ProductLight

    private int res;
    public int getRes() {
    return res;
}

public ProductLight(..... int res){
this.res= res;

}

并将它们添加到您的列表中

ProductLight product1 = new ProductLight(1,"Song Title 1, R.raw.youraudio1");
ProductLight product2 = new ProductLight(2,"Song Title 2, R.raw.youraudio2");
ProductLight product3 = new ProductLight(3,"Song Title 3, R.raw.youraudio3");

将音频索引存储在共享首选项中
