当我收到此错误时，我刚刚开始研究 recyclerView 并尝试使用自定义对象实现基本功能

我尝试了一些东西，但没有成功。我不知道我哪里错了。 这是我的适配器代码
public class WordsAdapter extends RecyclerView.Adapter<WordsAdapter.ViewHolder> {
private ArrayList<Words> mWords;
private Context mContext;
public WordsAdapter(Context context , ArrayList<Words> words)
{
mWords = words;
mContext = context;
}
private Context getContext(){return mContext;}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(getContext());
View view = inflater.inflate(R.layout.list_item , parent ,false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Words word = mWords.get(position);
TextView title = holder.title;
title.setText(word.getTitle());
TextView subtitle = holder.subtitle;
subtitle.setText(word.getSubtitle());
}
@Override
public int getItemCount() {
return mWords.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder{
public TextView title , subtitle;
public ViewHolder(View itemView) {
super(itemView);
title = (TextView) itemView.findViewById(R.id.title);
subtitle = (TextView) itemView.findViewById(R.id.subtitle);
}
}
}
这是我的 MainActivity java 文件
private static final String[] title = { "ABCD" , "EFGH" , "IJKL" , "MNOP", "QRST" , "UVW" , "XYZ"};
private static final String[] subtitle = {"abcd" , "efgh" , "ijkl" , "mnop" , "qrst", "uvw" , "xyz"};
private ArrayList<Words> words;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
words = new ArrayList<>();
for (int i=0 ; i<title.length ; i++)
{
words.add(new Words(title[i] , subtitle[i]));
}
RecyclerView rvWords = (RecyclerView) findViewById(R.id.rv_words);
WordsAdapter adapter = new WordsAdapter(MainActivity.this , words);
rvWords.setLayoutManager(new LinearLayoutManager(this));
rvWords.setAdapter(adapter);
}
}
这是我的布局项 xml 代码
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="?attr/titleTextAppearance"
android:textStyle="bold"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/subtitle"
android:textSize="?attr/subtitleTextAppearance"
/>
</LinearLayout>
以及回收器 View xml代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.sriran.recyclerview.MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/rv_words"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
请帮我找出哪里出错了
最佳答案
您可以删除代码以从父级 textsize 中获取，而不是使用
android:textSize="16dp"
因为系统无法获取subtitleTextAppearance。
