I want to hide footer button(activity_sign_up.xml) when
editText(fragment_sign_up_email_password) have focus.
I want to make the bottom button disappear at the same time when the soft keyboard is shown.

You can use the onGlobalLayoutListener to know when the keyboard is shown.
view?.viewTreeObserver?.addOnGlobalLayoutListener {
val rect = Rect()
view?.getWindowVisibleDisplayFrame(rect)
val screenHeight = view?.rootView?.height
val keypadHeight = screenHeight?.minus(rect.bottom) ?: return
if (keypadHeight > screenHeight * KEYBOARD_MINIMUM_HEIGHT_PERCENTAGE) {
//keyboard is shown do what ever you like
} else {
//keyboard is hidden
}
}

Thank you, #Gal Machluf I've tried your method, but After show soft keyboard, the bottom button disappears. What should I do?
[KeyboardVisibilityUtils.kt]
private val onGlobalLayoutListener = ViewTreeObserver.OnGlobalLayoutListener {
window.decorView.getWindowVisibleDisplayFrame(windowVisibleDisplayFrame)
val visibleDecorViewHeight = windowVisibleDisplayFrame.height()
Log.d("debugTest", "visibleDecorViewHeight : $visibleDecorViewHeight")
if (lastVisibleDecorViewHeight != 0) {
if (lastVisibleDecorViewHeight > visibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX) {
val currentKeyboardHeight = window.decorView.height - windowVisibleDisplayFrame.bottom
Log.d("debugTest","decorView height : ${window.decorView.height}, 현재보여지고 있는 크기의 가장 아래 : ${windowVisibleDisplayFrame.bottom}")
onShowKeyboard?.invoke(currentKeyboardHeight)
} else if (lastVisibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX < visibleDecorViewHeight) {
onHideKeyboard?.invoke()
}
}
lastVisibleDecorViewHeight = visibleDecorViewHeight
}

Android material TextInputLayout doesn't reconnect outline after setHintEnabled(false)

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.

Setting setOnClickListener on a Button in a View Stub

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

In the design tab, everything looks fine :
However, the problem arises in real devices :
However, if I add a view like this, the items cover the entire screen :
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/transparent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/like_btn" />
Any help would be really appreciated. Thanks in advance !!

I believe the problem is here:
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): FeedViewHolder {
return FeedViewHolder(ItemFeedBinding.inflate(LayoutInflater.from(parent.context)))
}
Because you are calling the overload of inflate() that does not specify a parent view, your item view's layout params are being ignored. Change it to this instead:
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): FeedViewHolder {
return FeedViewHolder(ItemFeedBinding.inflate(LayoutInflater.from(parent.context), parent, false))
}

you problem is
android:layout_height="wrap_content"
<TextView
android:id="#+id/post_content"
style="#style/SubHeading"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="16dp"
android:layout_marginEnd="16dp"
android:layout_marginRight="16dp"
android:gravity="start"
android:text="#{post.content}"
android:textAlignment="viewStart"
android:textSize="20sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/username"
tools:text="Anything random ...." />
you must set fixedHeight or use maxLines and set width to match_parent
also remove this line android:textAlignment="viewStart"

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?

Kotlin : same fragment, children with same tag

In my fragment, I have two linear layout with the same tag "result". Inside theses linear layouts, I have another layout with the tag "toggle" and a button with the tag "toggleButton".
I want that : when I click on my button, it toggle the linear layout "toggle" of its linear layout parent "result"
But when I do this :
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val root = rootLayoutResultSearch
root.findViewWithTag<Button>("toToggleButton")
val buttonToggle = view.findViewWithTag<Button>("toToggleButton")
buttonToggle.setOnClickListener{
Log.i(TAG, "click")
val toggle = view.findViewWithTag<LinearLayout>("toToggle")
if(toggle.visibility == View.GONE){
toggle.visibility = View.VISIBLE
}else{
toggle.visibility = View.GONE
}
}
}
it's working only for my first linear layout "result". When I click on my second button, it's not doing anything
Here the xml of the layouts "result" (I only post the first, the second is the exact same one)

Okay, I've thrown together a quick idea of what I think you want to accomplish. It excludes all the error and consistency checking one would normally want to do.
package com.example.toggler
import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.view.View
import android.widget.LinearLayout
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val list = arrayListOf<View>()
root_View.findViewsWithText(list, "toToggleButton", View.FIND_VIEWS_WITH_CONTENT_DESCRIPTION)
list.forEach { button ->
button.setOnClickListener { v: View ->
val viewParent = v.parent
if (viewParent is LinearLayout) {
val taggedView = viewParent.findViewWithTag<View>("toggle")
taggedView.visibility = when {
taggedView.visibility == View.GONE -> View.VISIBLE
else -> View.GONE
}
}
}
}
}
}
activity_main.xml

[EDIT]
Or, if you prefer to use tags:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
root_View.findViewsWithTag("toToggleButton").forEach { button ->
button.setOnClickListener { v: View ->
val viewParent = v.parent
if (viewParent is LinearLayout) {
val taggedView = viewParent.findViewWithTag<View>("toggle")
taggedView.visibility = when {
taggedView.visibility == View.GONE -> View.VISIBLE
else -> View.GONE
}
}
}
}
}
}
private fun ViewGroup.findViewsWithTag(tag: String): Sequence<View> {
return sequence {
for (index in 0 until childCount) {
val child = getChildAt(index)
when (child) {
is ViewGroup -> yieldAll(child.findViewsWithTag(tag))
is View -> if (child.tag == tag) yield(child)
}
}
}
}
