Question

我正在尝试制作电影列表，但它只显示带有应用名称的白色屏幕。显然，我有一个非常类似的程序，它运行得非常好。这是我运行程序时得到的结果。

W / OpenGLRenderer：无法选择带有EGL_SWAP_BEHAVIOR_PRESERVED的配置，重试没有...

我发现有人说如果xml代码中有错误会发生此错误，但我仍然会提供我的java代码。

public class MainActivity extends AppCompatActivity {

private ListView mListView;
private Context mContext;
ArrayList<Movie> movieList;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mContext = this;
    final ArrayList<Movie> movieList = Movie.getMoviesFromFile("movies.json", this);
    MovieAdapter adapter = new MovieAdapter(this, movieList);

    mListView = findViewById(R.id.movie_list_view);
    mListView.setAdapter(adapter);

    mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            Movie selectedMovie = movieList.get(i);

            Intent detailIntent = new Intent(mContext, MovieDetailActivity.class);
            detailIntent.putExtra("title", selectedMovie.title);
            detailIntent.putExtra("description", selectedMovie.description);
            detailIntent.putExtra("poster", selectedMovie.poster);

            startActivity(detailIntent);
        }
    });
}

以下是我的适配器。

public class MovieAdapter extends BaseAdapter{
private Context mContext;
private ArrayList<Movie> mMovieList;
private LayoutInflater mInflater;

public MovieAdapter(Context mContext, ArrayList<Movie> mMovieList){
    this.mContext = mContext;
    this.mMovieList = mMovieList;
    mInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount(){return mMovieList.size();}
@Override
public Object getItem(int pos){return mMovieList.get(pos);}
@Override
public long getItemId(int pos){return pos;}
@Override
public View getView(int pos, View convertView, ViewGroup parent){
    ViewHolder holder;

    if(convertView == null){
        convertView = mInflater.inflate(R.layout.list_item_movie, parent, false);
        holder = new ViewHolder();
        holder.titleTextView = convertView.findViewById(R.id.title);
        holder.charactersTextView = convertView.findViewById(R.id.main_characters);
        holder.descriptionTextView = convertView.findViewById(R.id.description);
        holder.thumbnailImageView = convertView.findViewById(R.id.poster);

        convertView.setTag(holder);
    } else{
        holder = (ViewHolder)convertView.getTag();
    }

    TextView titleTextView = holder.titleTextView;
    TextView descriptionTextView = holder.descriptionTextView;
    TextView charactersTextView = holder.charactersTextView;
    ImageView thumbnailImageView = holder.thumbnailImageView;
    Movie movie = (Movie)getItem(pos);

    titleTextView.setText(movie.title);
    titleTextView.setTextSize(20);

    charactersTextView.setText(movie.main_characters);
    charactersTextView.setTextSize(13);

    descriptionTextView.setText(movie.description);
    descriptionTextView.setTextSize(9);

    Picasso.with(mContext).load(movie.poster).into(thumbnailImageView);
    return convertView;
}

private static class ViewHolder{
    public TextView titleTextView;
    public TextView descriptionTextView;
    public ImageView thumbnailImageView;
    public TextView charactersTextView;
}

}

以下是xml代码。

有没有人有这方面的解决方案？

Answer 1

这仅是警告，并且由于重试时没有配置选项而没有（我从您的评论中假定）跟进错误，因此这不是问题的根源。

这不是一个不好的猜测，因为这是与OpenGL相关的类（android / opengl / EGL14），但这不是问题的根源。

您可以在https://www.khronos.org/egl上阅读有关EGL的更多信息。

Answer 2

可能不是您的解决方案的答案，但我遇到了同样的问题，它对我不起作用的原因是我的列表是空的。检查列表的大小并确保其不为零。
