Using com.google.android.material:material:1.6.1, when setting hint enabled to true and then to false, the outline gets broken. Here is the example code.
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val someHintButton = findViewById<MaterialButton>(R.id.someHintButton)
val noHintButton = findViewById<MaterialButton>(R.id.noHintButton)
val textInput = findViewById<TextInputEditText>(R.id.textInput)
val textLayout = findViewById<TextInputLayout>(R.id.textLayout)
someHintButton.setOnClickListener {
textInput.setText("Some text")
textLayout.setHintEnabled(true)
textLayout.setHint("Entered text:")
}
noHintButton.setOnClickListener {
textLayout.setHint(null)
textLayout.setHintEnabled(false)
textInput.setText("Some text will be entered here")
}
}
}

Screen after launch:
Screen after 'Some hint' pressed:
Screen after 'No hint' pressed:
setHint(null) or setHint("") don't do any difference. Why doesn't outline get reconnected? Please advise.

I am using TextInputLayout on Edit Profile screen and I wanted to update datas in that screen but when I used that, datas update to like
"com.google.android.material.textfield.TextInputLayout{9544eb3 V.ED..... ........ 93,232-931,455 #7f0a00d8 app:id/etEditName aid=1073741880}"

Thanks for your helps :)
You are updating the TextInputLayout itself when you need to update the text in the EditText inside the TextInputLayout. So
Replace
"name" to etName.toString(),
"surname" to etSurname.toString(),
"height" to etHeight.toString(),
"weight" to etWeight.toString(),
With
"name" to etName.editText?.text.toString(),
"surname" to etSurname.editText?.text.toString(),
"height" to etHeight.editText?.text.toString(),
"weight" to etWeight.editText?.text.toString(),
This will update user data in the Edit Profile screen.
I am following this tutorial to create an android app with space animation stuff. In the step titled "Transition Manager" you're instructed to add the following code to your MainActivity.kt file:
`
constraintSet1.clone(constraintLayout) //1
constraintSet2.clone(this, R.layout.activity_main) //2
departButton.setOnClickListener { //3
//apply the transition
TransitionManager.beginDelayedTransition(constraintLayout) //4
val constraint = if (!isOffscreen) constraintSet1 else constraintSet2
isOffscreen = !isOffscreen
constraint.applyTo(constraintLayout) //5
}
`
When this code is added the variable "constraintLayout" throws up an unresolved reference error
I think constraintLayout is supposed to be pointing to something in the xml and something is failing to make that happen, I just don't know what.
The kotlin code after adding the above block is:
`
package com.raywenderlich.android.razegalactic
import android.os.Bundle
import android.support.constraint.*
import android.support.v7.app.AppCompatActivity
import android.transition.TransitionManager
import kotlinx.android.synthetic.main.keyframe1.*
/**
* Main Screen
*/
class MainActivity : AppCompatActivity() {
private val constraintSet1 = ConstraintSet()
private val constraintSet2 = ConstraintSet()
private var isOffscreen = true
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.keyframe1)
switch1.setOnCheckedChangeListener { _, isChecked ->
switch1.setText(if (isChecked) R.string.round_trip else R.string.one_way)
constraintSet1.clone(constraintLayout) //1
constraintSet2.clone(this, R.layout.activity_main) //2
departButton.setOnClickListener { //3
//apply the transition
TransitionManager.beginDelayedTransition(constraintLayout) //4
val constraint = if (!isOffscreen) constraintSet1 else constraintSet2
isOffscreen = !isOffscreen
constraint.applyTo(constraintLayout) //5
}
}
}
}

can anyone tell me what I might be missing or how this can be fixed?
Thanks in advance.
You're suppose to reference a view from the xml before you can use it.
Do this, also if the name of the layout the MainActivity is suppose to use is main.xml, it should be the one your setContentView use not some other layout.
lateinit var cosntraintLayout: ConstraintLayout
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main) // <- main.xml
cosntraintLayout = findViewById<ConstraintLayout>(R.id.ConstraintLayout) // <- add this line
...
...
}
switch1 and departButton will also throw the same error, but I'll leave it for you to figure it out based on the code I provided.
I'm creating a View Stub for my login screen, however I have a question. When I try to set an setOnClickListener on my login button in my viewstub_login.kt file, the button action won't go through. Do I need to change my extension on my Kotlin file, or do I need to put my setOnClickListener in the onStart() function? Thank you!

click listener is correct, but inside the block, your code is not correct
because emailText and passwordText is not null, as you have defined above, thus the if condition returning false and your code just going over it

and the following code -

val bundle = Bundle()
bundle.putParcelable(Constants.INSPECTION, inspection)
inspectionDetailsFragment.arguments = bundle
return inspectionDetailsFragment

}
...

}
//Inside another Fragment

)

fragment?.let {
fragmentTransaction
.replace(containerId, it, it::class.java.simpleName)

}
}
For some reason when trying to navigate to the InspectionDetailsFragment the app crashes with the No view found for id 0x7f0900df (com.supercom.myapplication:id/fragment_inspection_details_root) for fragment InspectionDetailsFragment I really have no idea what's wrong, I tried to look up but it seems like I am doing everything correct.
The InspectionDetailsFragment used to have a container fragment for it but I deleted it, maybe that is related to the issue I am getting?
I'm trying to create a Two-Way Data binding connection with a LiveData object of a modal class. But when I tries to read the values of user it turns out to be null. Here is my code -
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val viewModal: MainActivityViewModal = ViewModelProvider(
this,
MainActivityViewModalFactory()
).get(MainActivityViewModal::class.java)
val binding = DataBindingUtil.setContentView<ActivityMainBinding>(
this,
R.layout.activity_main
).apply {
this.lifecycleOwner = this#MainActivity
this.viewModal = viewModal
}
}}
Here is the Layout file -

Here is the ViewModal
class MainActivityViewModal : ViewModel() {
var user = MutableLiveData<User>()
fun login() {
println("Login Success ${user.value}")
}}
And here is the Modal Class
class User() {
var userName: String = ""
var password: String = ""
override fun toString(): String {
return "User(userName='$userName', password='$password')"
}}
Please tell me any solution or a good way around to this problem
In the MainActivityViewModal define user as just User type rather as MutableLiveData.
