集中在回收站视图中的编辑文本上时出错

Question

我有一个 RecyclerView。 回收站视图中的每一行都有一个编辑文本组件。

当键盘不可见时，应用程序崩溃，并且用户点击了任何 EditText 组件在键盘弹出后将被占用的区域。 也就是说，屏幕上半部分的EditText框不会抛出异常。

此错误特定于运行 Android 6.0 或更高版本的设备。

对于版本低于 Android 6.0 的设备，该应用运行良好，因为 EditText 会自动滚动到键盘上方。

以下是例外。

以下是我的适配器代码：

public class StudentAdapter extends RecyclerView.Adapter<StudentAdapter.ViewHolder> {

private Context context;
private List<User> dataList;
private ImageLoader mImageLoader;

public StudentAdapter(List<User> dataList) {
    this.dataList = dataList;
    this.mImageLoader = CustomVolleyRequestQueue.getInstance(AppName.getInstance().getApplicationContext()).getImageLoader();
}

public List<User> getDataList() {
    return dataList;
}


@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    context = parent.getContext();
    LayoutInflater inflater = LayoutInflater.from(context);

    View itemView = inflater.inflate(R.layout.item_exam_student, parent, false);

    ViewHolder viewHolder = new ViewHolder(itemView);
    return viewHolder;
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
    final User std = dataList.get(position);

    RelativeLayout studentHolder = viewHolder.studentHolder;
    NetworkImageView imgStudentPic = viewHolder.imgStudentPic;
    final TextView tvName = viewHolder.tvName;
    final EditText etMarks = viewHolder.etMarks;

    tvName.setText(std.toString());
    etMarks.setVisibility(View.GONE);
}

@Override
public int getItemCount() {
    return dataList.size();
}

@Override
public int getItemViewType(int position) {//VVIMP : used to maintain the state of scrolled items.
    //Resource : http://stackoverflow.com/questions/32065267/recyclerview-changing-items-during-scroll
    return position;
}

public static class ViewHolder extends RecyclerView.ViewHolder {

    public RelativeLayout studentHolder;
    public NetworkImageView imgStudentPic;
    public TextView tvName;
    public EditText etMarks;

    public ViewHolder(View itemView) {
        super(itemView);

        studentHolder = (RelativeLayout) itemView.findViewById(R.id.studentHolder);
        imgStudentPic = (NetworkImageView) itemView.findViewById(R.id.imgStudentPic);
        tvName = (TextView) itemView.findViewById(R.id.tvName);
        etMarks = (EditText) itemView.findViewById(R.id.etMarks);
    }
}
}

Answer 1

您好，这是适配器的代码，我成功地使用包含每行编辑文本的回收器视图滚动。 公共类 MovieAdapter 扩展 RecyclerView.Adapter {

private List<Movie> movieList;

@Override
public MovieHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.movie_list_row, parent, false);

    return new MovieHolder(itemView);
}

@Override
public void onBindViewHolder(MovieHolder holder, int position) {
    Movie movie = movieList.get(position);

    holder.ed.setText(movie.getTitle());
}
public MovieAdapter(List<Movie> movieList)
{

    this.movieList = movieList;
}


@Override
public int getItemCount() {
    return movieList.size();
}



class MovieHolder extends RecyclerView.ViewHolder
{

    public EditText ed;
    public MovieHolder(View view)
    {
        super(view);

        ed = (EditText) view.findViewById(R.id.name);
    }
}}

MainActivity 类代码：

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
    mAdapter = new MovieAdapter(movieList);

    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerView.setLayoutManager(mLayoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(mAdapter);

如果您仍然遇到问题，请告诉我。

谢谢

我在 android 清单文件的活动标签中添加了以下内容。

android:windowSoftInputMode="adjustPan"

这只是一个临时解决方案，因为用户体验问题很少。

实际问题可以在这个问题中研究：Recyclerview not scrolling to end when keyboard opens
