android - onBindViewHolder 使用 RecyclerView 在 setText 处崩溃

Question

我正在尝试实现自定义 RecyclerView.Adaper 以用于虚拟/POC RecyclerView 应用程序。我正在使用 this教程。我的模型名为 Movie 并且有两个字段:

@NonNull
@PrimaryKey
private String name;

@NonNull
private Integer releaseYear;

所以我有这门课

MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MyViewHolder>

覆盖 onCreateViewHolder、onBindViewHolder 和 getItemCount 并定义 MyViewHolder extends RecyclerView.ViewHolder。

当调试行位于 onBindViewHolder 的最后一行时:

// Involves populating data into the item through holder
@Override
public void onBindViewHolder(@NonNull MyViewHolder viewHolder, int position) {
    // Get the data model based on position
    Movie movie = movies.get(position);

    // Set item views based on your views and data model
    TextView tvMovieName = viewHolder.tvMovieName;
    tvMovieName.setText(movie.getName());

    TextView tvMovieReleaseYear = viewHolder.tvMovieReleaseYear;
    tvMovieReleaseYear.setText(movie.getReleaseYear());
}

我明白了

    at br.com.basicfeatures.presentation.adapter.MovieAdapter.onBindViewHolder(MovieAdapter.java:15)

这是 MyViewHolder:

protected class MyViewHolder extends RecyclerView.ViewHolder {
    private TextView tvMovieName;
    private TextView tvMovieReleaseYear;

    private MyViewHolder(@NonNull View itemView) {
        super(itemView);
        this.tvMovieName = itemView.findViewById(R.id.id_tv_movie_name);
        this.tvMovieReleaseYear = itemView.findViewById(R.id.id_tv_movie_release_year);
    }
}

Answer 1

这是因为 movie.getReleaseYear() 返回一个整数，所以 tvMovieReleaseYear.setText 试图找到不存在的相应资源文件。所以你需要的是将 movie.getReleaseYear() 转换为 String

tvMovieReleaseYear.setText(movie.getReleaseYear() + "");
