Share web url from browser to navigation fragment-CodePudding

In my app I had only one activity and 3 fragments(mainF,saveF,updateF).

Main activity only set layout activity_main and this activity layout only set navHost Fragment. I want to send url from browser to one of the fragments, like browser ->share url ->fragment ->save.

Previously this app have two activities, so I used intent filters and get the url and stored in the view. But how to share it directly in the fragments in nav graph.

class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    if (intent?.action == Intent.ACTION_SEND) {
        if ("text/plain" == intent.type) {
            intent.getStringExtra(Intent.EXTRA_TEXT)?.let {

                val navController = findNavController(R.id.navHostFragment)
                val bundle = Bundle()
                bundle.putString("urlFromWeb",it)
                navController.navigate(R.id.saveFragment,bundle)
            }
        }
    }
}

}

my activity_main xml

    app:navGraph="@navigation/main_navigation_file">

CodePudding user response：

You can receive that data in the Main Activity just like before and open the required navigation fragment bypassing that received data with it.

We can not directly access nav contoller from our activity .So this method is used.

Main acitivity

class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    if (intent?.action == Intent.ACTION_SEND) {
        if ("text/plain" == intent.type) {
            intent.getStringExtra(Intent.EXTRA_TEXT)?.let {
               val navHost = supportFragmentManager.findFragmentById(R.id.navHostFragment) as NavHostFragment
                val navContoller = navHost.findNavController()
                val bundle = Bundle()
                bundle.putString("url",it)
                navContoller.navigate(R.id.saveFragment,bundle)
            }
        }
    }
}

}

saveFragment where intent will be used

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val view = inflater.inflate(R.layout.fragment_save, container, false)
    // Getting the text that is sent from the MainActivity
    val message = arguments?.getString("url")

    titleEdit = view.findViewById(R.id.bookmark_title)
    urlEdit = view.findViewById(R.id.bookmark_url)
    descripEdit = view.findViewById(R.id.description_EditText)!!
    saveBtn = view.findViewById(R.id.savebtn)
    
    // Using that text in our view
    if (message != null) {
            urlEdit.setText(message)
    }
