我的recyclerview中有一个最喜欢的复选框。我的问题是在recyclerview内部无法点击复选框。我必须将勾选的recyclerview项目传递给另一个recyclerview。真的我被困在这里。有人请帮助我。提前致谢。

删除onClickListener并设置onCheckedChangeListener。然后将列表保存到Sharedpreference
中的数组viewHolder.mCheck.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
Snackbar snackbar = Snackbar.make(viewHolder.itemView, "Item Favorited", Snackbar.LENGTH_SHORT);
snackbar.show();
} else {
Snackbar snackbar = Snackbar.make(viewHolder.itemView, "Item Unfavorited", Snackbar.LENGTH_SHORT);
snackbar.show();
}
int position = viewHolder.getAdapterPosition();
mCheckedItems.put(position, isChecked);
List<Integer> selected = new ArrayList<>();
for (int i = 0; i < mCheckedItems.size(); i++) {
final boolean checked = mCheckedItems.valueAt(i);
if (checked) {
selected.add(mCheckedItems.keyAt(i));
}
}
Log.e("Checked Array = ", String.valueOf(selected));
SharedPreferences prefs = v1.getContext().getSharedPreferences("my_prefs", Context.MODE_PRIVATE);
SharedPreferences.Editor edit = prefs.edit();
edit.putString("Checkbox", String.valueOf(selected));
edit.commit();
Log.e("Shared Preference = ", String.valueOf(edit));
}
});
