Question

我想获取所选文件夹的位置并获取其ID ...它在列表视图中运行良好，但是现在我更改为recycleview，并且我不知道如何获取它的位置。

lst.setOnClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            // String folder = lst.getItemAtPosition( lst.getSelectedItemPosition()).toString();
            String folder = (String) lst.getItemAtPosition(i);
            String id = (String) lstMap.get(i);

            Toast.makeText(getApplicationContext(),"Vous avez choisis "+ id,Toast.LENGTH_LONG).show();


            String newReq= new StringBuilder().append(AppConfig.URL_GetFoldersFK).append(id).toString();
            Log.d("Request show",newReq);

            Intent intent = new Intent(MainActivity.this, BuildingsListActivity.class);
            // Sending value to another activity using intent.
            intent.putExtra("FolderId", newReq);
            startActivity(intent);
        }
    });

Answer 1

在RecyclerView适配器中，您应该在onBindViewHolder()方法中执行以下操作：

@Override
public void onBindViewHolder(final MyViewHolder holder, final int position){
    String id = (String) lstMap.get(position);

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(mContext, BuildingsListActivity.class);
            intent.putExtra("FolderId", id);
            mContext.startActivity(intent);
        }
    });
}

Answer 2

viewholder将返回所选视图在position中的位置。
您还可以使用通过适配器内onBindViewHolder(...)方法传递的// Immutable Selection List of Users .form-group label.col-md-4.control-label Current Users .col-md-4 .input-group list-group#currentUsers(name='currentUsers') for admin in config.admins li.list-group-item #{admin} .form-group label.col-md-4.control-label Apply Changes .col-md-4 .input-group button.btn.btn-primary(type='submit') Save

recycleview中的getItemAtPosition
