fragment

问题 I'm trying to implement a BaseFragment in which I will pass the layout resource on it and it should outputs the binding to work in the fragment itself instead of need to do it everytime the fragment is extended. For example I have this BaseFragment open class BaseFragment(@LayoutRes contentLayoutId : Int = 0) : Fragment(contentLayoutId) { private lateinit var onInteractionListener: OnFragmentInteractionListener val toolbar : Toolbar? get() { return if(activity is BaseActivity) (activity as

问题 I have an AudioPlayerFragment to which I pass some url with setArguments(). If I have an url key in the getArguments() of my instance of AudioPlayerFragment , I start a service that plays the audio stream. If there was already a stream playing, I stop it and start it again with the new stream. If there is no arguments, I do nothing. My problem is that the arguments are kept with the instance, so when I get back to it, getArguments() returns the latest arguments set, if no new have been set.

问题 I'm having a problem with saving data permanently. It should be simple, I'm sending data to another Fragment and it works perfectly, however, I have no idea how to save data. I tried something, but I was wondering if you could help me out. In my code, I'm sending a data to another Fragment by pushing a Button. So this is the code: package com.example.mskydraw.notetech; import android.content.Context; import android.content.SharedPreferences; import android.os.Bundle; import android.support.v4
