我正在按照本教程开发一个简单的Android应用程序。我在此消息的onBindViewHolder方法上遇到编译错误:错误:方法未覆盖或从超类型实现方法这是我的代码:import android.support.annotation.NonNull;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;public class CryptogramPairingAdapter extends RecyclerView.Adapter { private String[] mDataset; // Provide a reference to the views for each data item // Complex data items may need more than one view per item, and // you provide access to all the views for a data item in a view holder public static class ViewHolder extends RecyclerView.ViewHolder { // each data item is just a string in this case public TextView mTextView; public ViewHolder(TextView v) { super(v); mTextView = v; } } // Provide a suitable constructor (depends on the kind of dataset) public CryptogramPairingAdapter(String[] myDataset) { mDataset = myDataset; } // Create new views (invoked by the layout manager) @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { // create a new view TextView v = (TextView) LayoutInflater.from(parent.getContext()) .inflate(R.layout.pair_crypto_recyclerview, parent, false); CryptogramPairingAdapter.ViewHolder vh = new ViewHolder(v); return vh; } // Replace the contents of a view (invoked by the layout manager) @Override public void onBindViewHolder(ViewHolder holder, int position) { // - get element from your dataset at this position // - replace the contents of the view with that element holder.mTextView.setText(mDataset[position]); } // Return the size of your dataset (invoked by the layout manager) @Override public int getItemCount() { return mDataset.length; }}我很困惑,因为代码与引用几乎相同(除了修改后的名称)。

我建议你改变你的ViewHolder
被命名为比其他的东西ViewHolder
,因为它是有冲突的ViewHolder
,并简单地去给你带来的混乱区分ViewHolder
从ViewHolder
。
给定当前状态的代码,请更改:
public class CryptogramPairingAdapter extends RecyclerView.Adapter
至:
public class CryptogramPairingAdapter extends RecyclerView.Adapter<CryptogramPairingAdapter.ViewHolder>
