应用程序重新启动后如何保存此切换按钮的状态？

Question

CLICK HERE FOR IMAGE

我尝试了SharedPreferences，但没有成功。 为什么不保存toogle状态？

我正在使用RegleerView中的一个切换按钮。

这是我的onBindViewHolder（）代码：

@Override
    public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {

        final ToggleModel toggleModel = toggleModelList.get(position);

        if(toggleModel.isFavorite())
            holder.toggle_btn.setBackgroundResource(toggleModel.getToggled());
        else
            holder.toggle_btn.setBackgroundResource(toggleModel.getUntoglled());

        //Set title from model
        holder.textView.setText(toggleModel.getTitle());
        ((ViewHolder) holder).copybutton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                // Toast.makeText(view.getContext(), "dfdfd", Toast.LENGTH_SHORT).show();

                ClipboardManager cm = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
                cm.setText(holder.textView.getText().toString());
                Toast.makeText(context, "Copied :)", Toast.LENGTH_SHORT).show();
            }
        });

        holder.toggle_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final SharedPreferences preferences = context.getSharedPreferences("save",Context.MODE_PRIVATE);
                if (toggleModel.isFavorite) {
                    toggleModel.setFavorite(false);
                    Toast.makeText(context, "UNFavorited", Toast.LENGTH_SHORT).show();


                    SharedPreferences.Editor editor = preferences.edit();
                    editor.putBoolean("tgpref", false); // value to store
                    editor.apply();

                }
                else {
                    toggleModel.setFavorite(true);
                    Toast.makeText(context, "Favorited", Toast.LENGTH_SHORT).show();
                    SharedPreferences.Editor editor = preferences.edit();
                    editor.putBoolean("tgpref", true); // value to store
                    editor.apply();
                    //Log.e("IN ELSE PART",editor.apply());
                }

                notifyItemChanged(position);

            }
        });
 }
