【问题描述】：
我想在单击回收器视图的对象时显示另一个活动。例如：如果我单击“dd”文本或“该行的图像”，那么我应该转到名为“AbcActivity”的活动。
它去了很多网站，看过 youtube 教程但没有帮助。请帮帮我。请帮帮我，这是我最后的希望:(
我是这方面的初学者，如果你能提供项目就太好了。
这是主要活动：
public class MainActivity extends AppCompatActivity implements WordAdapter.OnNoteListener {
private RecyclerView recyclerView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.home_view);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
List<Word> wordList = new ArrayList<>();
wordList.add(new Word(R.drawable.ic_launcher_background, "dd"));
wordList.add(new Word(R.drawable.ic_launcher_background, "ss"));
WordAdapter adapter = new WordAdapter(wordList, this);
recyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
@Override
public void onNoteClick(int position) {
}
}
字适配器：
public class WordAdapter extends RecyclerView.Adapter<WordAdapter.viewholder> {
private List<Word> wordList;
private OnNoteListener mOnNoteListener;
public WordAdapter(List<Word> wordList, OnNoteListener onNoteListener) {
this.wordList = wordList;
this.mOnNoteListener = onNoteListener;
}
@NonNull
@Override
public viewholder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_items, viewGroup, false);
return new viewholder(view, mOnNoteListener);
}
@Override
public void onBindViewHolder(@NonNull viewholder viewholder, int position) {
int resource = wordList.get(position).getImageResource();
String title = wordList.get(position).getTitle();
viewholder.setData(resource, title);
}
@Override
public int getItemCount() {
return wordList.size();
}
class viewholder extends RecyclerView.ViewHolder implements View.OnClickListener{
private ImageView imageView;
private TextView title;
OnNoteListener onNoteListener;
public viewholder(@NonNull View itemView, OnNoteListener onNoteListener) {
super(itemView);
imageView = itemView.findViewById(R.id.image);
title = itemView.findViewById(R.id.word);
this.onNoteListener = onNoteListener;
itemView.setOnClickListener(this);
}
private void setData(int resource, String titleText){
imageView.setImageResource(resource);
title.setText(titleText);
}
@Override
public void onClick(View view) {
onNoteListener.onNoteClick(getAdapterPosition());
}
}
public interface OnNoteListener {
void onNoteClick(int position);
}
}
这是一个词：
public class Word implements Parcelable {
private int imageResource;
private String title;
public Word(int imageResource, String title) {
this.imageResource = imageResource;
this.title = title;
}
protected Word(Parcel in) {
imageResource = in.readInt();
title = in.readString();
}
public static final Creator<Word> CREATOR = new Creator<Word>() {
@Override
public Word createFromParcel(Parcel in) {
return new Word(in);
}
@Override
public Word[] newArray(int size) {
return new Word[size];
}
};
public int getImageResource() {
return imageResource;
}
public String getTitle() {
return title;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeInt(imageResource);
parcel.writeString(title);
}
}
【问题讨论】：
-
onNoteClick() 方法的实现在哪里？？
-
让你的viewholder类实现接口方法。然后根据适配器的位置选择你想要去的活动

嗨 Jeeva，我是这个领域的初学者，你能提供我在回收站视图中通过添加图像和文本以及 OnCreate 方法制作的项目吗？请问？
