如何在 RecyclerView onclick 方法中使用 bundle 发送数据

Question

我想在 recycler view oclick 中发送我的姓名和图像，但我有点困惑我应该使用 paraceble 或简单的捆绑机制如何发送和接收它

public class FamousPeople

{
private static final String FAMOUS_NAME = "famous name";
private static final String FAMOUS_PHOTO="photo";
private String name;
private int photo;
private String details;

FamousPeople(String name, int photo) {

    this.name = name;
    this.photo = photo;
}
public  FamousPeople(){


}


public String getDetails() {
    return details;
}

public void setDetails(String details) {
    this.details = details;
}

public int getPhoto() {
    return photo;
}

public void setPhoto(int photo) {
    this.photo = photo;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}


   }

我必须在其中传递图像和文本数据的 BiographyViewHolder 类

 class BiographyViewHolder extends RecyclerView.ViewHolder
       implements View.OnClickListener {

   public TextView textView;
  public ImageView imageView;
List<FamousPeople> famousPeoples=GetData.getListdata();


public BiographyViewHolder(View itemView)
{
    super(itemView);
    itemView.setOnClickListener(this);
    textView= (TextView) itemView.findViewById(R.id.country_name);
    imageView= (ImageView) itemView.findViewById(R.id.country_photo);


}

@Override
public void onClick(View view) {
    Intent  intent=new Intent();
    Bundle bundle=new Bundle();

    intent.putExtras(bundle);
    view.getContext().startActivity(intent);

}

 }

GetData 类从这个类中获取数据

     public  class GetData {
    public static List<FamousPeople> getListdata() {
    List<FamousPeople> famousPeoples = new ArrayList<>();
    famousPeoples.add(new FamousPeople("rahul", R.drawable.amitabh));
    famousPeoples.add(new FamousPeople("sumit", R.drawable.cvraman));
    famousPeoples.add(new FamousPeople("neha", R.drawable.indira));
    famousPeoples.add(new FamousPeople("surbhi", R.drawable.kishorkumar));
    famousPeoples.add(new FamousPeople("rahul", R.drawable.modi));
    famousPeoples.add(new FamousPeople("sumit", R.drawable.mother));
    famousPeoples.add(new FamousPeople("neha", R.drawable.nehru)) 

    return famousPeoples;
}

Answer 1

尝试编辑您的onClick() 函数，如下所示。 您只需要从列表中获取由getAdapterPosition 指向的数据，然后将它们传递给bundle

    @Override
        public void onClick(View v) {
            Intent  intent=new Intent();
            Bundle bundle=new Bundle();
            bundle.putInt("IMAGE", famousPeoples.get(getAdapterPosition()).getPhoto());
            bundle.putString("NAME", famousPeoples.get(getAdapterPosition()).getName());
intent.putExtras(bundle);
    view.getContext().startActivity(intent);

}

Answer 2

@Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view=inflater.inflate(R.layout.fragment_detail, container, false);
   textView= (TextView) view.findViewById(R.id.bioname);
    imageView= (ImageView) view.findViewById(R.id.imageView);
    Bundle getBundle = null;
    getBundle = getActivity().getIntent().getExtras();

    String name = getBundle.getString("NAME");
    int id = getBundle.getInt("IMAGE");
    textView.setText(name);
    imageView.setImageResource(id);
    return view;
}

Answer 3

要获取 image 和 name ，你必须这样做，

例如：您的点击事件发送数据 onClick();

ViewHolder VHheaderItem = (ViewHolder) view;

    VHheaderItem.image_detail.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            Intent i = new Intent(CurrentClass.this, AnotherClass.class);
                            i.putExtra("Name", listItems1.get(position).getVarName(););
                            startActivity(i);
                        }
                    });

收到它，

String drName = getIntent().getStringExtra("Name");

现在如果你想通过意图传递图像那么

imageView.buildDrawingCache();
Bitmap image= imageView.getDrawingCache();

Bundle extras = new Bundle();
extras.putParcelable("imagebitmap", image);
intent.putExtras(extras);
startActivity(intent);

收到它，

Bundle extras = getIntent().getExtras();
Bitmap bmp = (Bitmap) extras.getParcelable("imagebitmap");

image.setImageBitmap(bmp);
