【问题讨论】：

您可以为此使用共享偏好
Android 为此提供了lot of options。共享首选项是这样的简单存储方式。
您可以使用共享首选项来存储按钮的切换状态并在需要时重新填充它

【解决方案1】：

使用相同的共享首选项。

togButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                     int notification_status = Integer.parseInt(mPreferences.getString("status", "-1"));
                    SharedPreferences.Editor editor=mPreferences.edit();
                    Log.i("notification_status="+notification_status,"888");
                    if(notification_status==-1){
                          editor.putString("status", "1");
                          holder.notification_btn.setBackgroundResource(R.drawable.notification_on);
                          //do your stuff
                    }else if(notification_status==1){
                        editor.putString("status", "0");
                        holder.notification_btn.setBackgroundResource(R.drawable.notification_off);
                        //do your stuff
                    }else if(notification_status==0){
                        editor.putString("status", "1");
                        holder.notification_btn.setBackgroundResource(R.drawable.notification_on);
                        //do your stuff
                    }
                    editor.commit();
                }
            });

【解决方案2】：

使用共享偏好作为以下类

public class YourPreferenes {

    private Context mContext;
    private SharedPreferences mPrefs;
    private static YourPreferenes mYourPreferenes;
    private YourPreferenes(Context ctx){
        mContext = ctx;
        mPrefs = mContext.getSharedPreferences("ATSPreferenes", Context.MODE_PRIVATE);
    }

    public static ATSPreferenes getInstance(Context ctx){
        if(mYourPreferenes == null){
            mYourPreferenes = new YourPreferenes(ctx);
        }
        return mYourPreferenes;
    }

    public void setButtonState(boolean btnstate){
        SharedPreferences.Editor editor = mPrefs.edit();
        editor.putBoolean("btnstate", btnstate);
        editor.commit();
    }

    public boolean getButtonState(){
        return mPrefs.getBoolean("btnstate", false);
    }
}


And get your saved togalbutton stat even you kill your app.
