Answer 1

用于sharedpreference保存每个切换按钮的状态并从sharedpreference

就像您可以在 sharedpreference 中定义切换状态（具有唯一 ID）一样

在自定义适配器中定义了共享首选项值。

final ToggleButton tgl=(ToggleButton)row.findViewById(R.id.tglalertstatus);

            tgl.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                    if(isChecked)
                    {
                        SharedPreferences contact = context.getSharedPreferences(
                                "contact", 1);

                        editor = contact.edit();

                        editor.putInt("toggle"+tgl.getContentDescription().toString(), 1); // i set the content description for each toggle a unique string so it will work as a key for shared preference. 

                        editor.commit();
                    }
                    else
                    {
                        SharedPreferences contact = context.getSharedPreferences(
                                "contact", 1);

                        editor = contact.edit();

                        editor.putInt("toggle"+tgl.getContentDescription().toString(), 0);//i set the content description for each toggle a unique string so it will work as a key for shared preference.

                        editor.commit();
                    }

                }
            });

希望这会有所帮助。
