Passing views to a second fragment screen does not display them correctly-CodePudding

I am getting an an error when I try to display 2 input views. They are captured in one fragment screen and then I try to display them on a second fragment screen. The navigation works but they display as resources?... i do not even know what it is called.

This is the setOnClickListener that calls up that screen. I suspect it has something to go with safeArgs

binding.buttonConfirm.setOnClickListener{
    val username = binding.editTextUsername.toString()
    val password = binding.editTextPassword.toString()
    val action = LoginFragmentDirections.actionLoginFragmentToWelcomeFragment(username, password) // this is generated class due to nav graph
    findNavController().navigate(action)
}

in Debugger i added some watches

I am a newbie to Android, and to stackoverflow as a poster. Thanks for any help

CodePudding user response：

You're calling toString() on the EditText and not actually getting the text the user has entered - to do that, you need to call getText() which in Kotlin code, you can do via the text property:

val username = binding.editTextUsername.text.toString()
val password = binding.editTextPassword.text.toString()
val action = LoginFragmentDirections.actionLoginFragmentToWelcomeFragment(username, password) // this is generated class due to nav graph
findNavController().navigate(action)

CodePudding user response：

You are taking the view itself instead of its value. To do so, grab the value, not the view.

binding.buttonConfirm.setOnClickListener{
val username = binding.editTextUsername.text.toString()
val password = binding.editTextPassword.text.toString()
val action = LoginFragmentDirections.actionLoginFragmentToWelcomeFragment(username, password) // this is generated class due to nav graph
    findNavController().navigate(action)
}

Alternatively, you can pass data between destinations with Bundle objects.

Create a Bundle object and pass it to the destination using navigate(), as shown below:

val bundle = Bundle()
bundle.putString("username", binding.editTextUserName.text.toString())
bundle.putString("password", binding.editTextPassword.text.toString())
view.findNavController().navigate(R.id.actionLoginFragmentToWelcomeFragment, bundle)

In your receiving destination’s code, use the getArguments() method to retrieve the Bundle and use its contents:

binding.textViewUserName.text = arguments?.getString("username")
binding.textViewPassword.text =arguments?.getString("password")
