java - 在 RecyclerView 关注之前的 EditText

Question

我在 RecyclerView 中有一些垂直的 EditText。

当我在下半个垂直屏幕上触摸 EditText 时。将光标移到上一个 EditText 上并关注它。

我对此进行了搜索，但找不到任何解决方案。

请帮忙..

我正在点击位于回收站 View 位置 10 的编辑文本。

但 android 专注于编辑位置 9 的文本

public class inputsAdapter extends RecyclerView.Adapter<holder> implements View.OnFocusChangeListener {
    public List<String> paramList,resultList;
    Context mContext;
    boolean doneParam,doneResult;
    public View focusedView;
    public ArrayAdapter<String> adapter ;
    public inputsAdapter(List<String> paramList, List<String> resultList, Context mContext) {
        this.paramList = paramList;
        this.resultList = resultList;
        this.mContext = mContext;
        this.doneParam=false;
        this.doneResult=false;
        this.focusedView=null;
        this.adapter = new ArrayAdapter<String>
                (mContext,android.R.layout.simple_list_item_1,mContext.getResources().getStringArray(R.array.correct_params) );
    }

    @Override
    public holder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.parameter_row,parent,false);
        return new holder(view);
    }

    @Override
    public void onBindViewHolder(holder holder, final int position) {
        if(position<paramList.size()){
            holder.paramConst.setVisibility(View.VISIBLE);

您的 getItemCount 方法返回了错误的值。您不需要为其添加 +1。因此，将您的方法更改为以下代码，看看它是否解决了您的问题:

@Override
public int getItemCount() {
    if(paramList.size()>resultList.size())
        {return paramList.size();}
    else {return resultList.size(); }
}
