我自己定义了一个类继承了RecyclerView.Adapter
//这个是我自定义的类，用来继承RecyclerView.Adapter
public abstract class TableAdapter<VH extends RecyclerView.ViewHolder> extends RecyclerView.Adapter {
}
//这个是我继承的类
public abstract static class Adapter<VH extends ViewHolder> {
//这个类主要就这两个abstract方法
public abstract VH onCreateViewHolder(ViewGroup parent, int viewType);
public abstract void onBindViewHolder(VH holder, int position);
然后我用一个类来继承我自定义的这个Adapter的话：
class MyAdapter extends TableAdapter<MyAdapter.ViewHolder> {
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return null;
}
@Override
public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {
}
@Override
public int getItemCount() {
return 0;
}
class ViewHolder extends RecyclerView.ViewHolder {
TextView name;
TextView kill;
TextView dead;
public ViewHolder(View itemView) {
super(itemView);
name = (TextView) f(R.id.name);
kill = (TextView) f(R.id.kill);
dead = (TextView) f(R.id.dead);
}
private View f(int id) {
return findViewById(id);
}
}
}
就会报错：
但是如果我直接继承RecyclerView.Adapter，就没问题：
class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return null;
}
@Override
public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {
}
@Override
public int getItemCount() {
return 0;
}
class ViewHolder extends RecyclerView.ViewHolder {
TextView name;
TextView kill;
TextView dead;
public ViewHolder(View itemView) {
super(itemView);
name = (TextView) f(R.id.name);
kill = (TextView) f(R.id.kill);
dead = (TextView) f(R.id.dead);
}
private View f(int id) {
return findViewById(id);
}
}
}
请问这哪里有问题吗？
