I have a survey activity which consists of option types as radio button, checkbox, textbox. I am using EditText to get user's response for text box. I am inflating the EditText dynamically from recycler view adapter.
But whenever this activity is called, keyboard also pops up with the cursor in the EditText box. But I only want the keyboard to open only when the user touches on the EditText. I have tried few possible methods, but didn't work and need your assistance. Thanks in advance!!
fun showTextBox(answerLL : LinearLayout, currentItem : QuestionList, position: Int, draftOptions : MutableList<Draft>) {
answerLL.removeAllViews()
var optMaster : OptionMaster
answerLL.setPadding(0, 0, 55, 0)
val et = EditText(mActivity)
et.setMinLines(1);
et.setMaxLines(10);
et.setCursorVisible(true);
et.requestFocusFromTouch();
// et.requestFocus()
et.setFocusableInTouchMode(true)
val lp = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
et.setLayoutParams(lp);
et.setTextIsSelectable(true);
et.setGravity(Gravity.START);
et.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
et.setPaddingRelative(15, 7, 7, 7);
et.setPadding(15, 7, 7, 7);
et.setTextColor(Color.BLACK);
et.addTextChangedListener(object: TextWatcher{
override fun afterTextChanged(s: Editable?) {
textListener.textValueEntered(currentItem.questionMaster.qmID, s.toString())
}
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
}
})
for(draft in draftOptions){
if (draft.quesId == currentItem.questionMaster.qmID){
et.setText(draft.optValue)
}
}
answerLL.addView(et)
}
check your windowSoftInputModeattribute in manifest file, activity tag
I am developing an open source text masker. You can click here to see source code.
My problem is that, when I wrap my custom edit text with TextInputLayout, onTextChanged is being triggered twice only for first letter. Then it works as expected.
This "twice call" breaks my logic. Do you guys have any idea what might be the problem? Since it is being used by other developers, I don't want to fix it with hacky solution. I need to find out the problem.
I set text manually after removing text watcher, then I add text watcher again.
Here is my main logic;
This method is being called only once;
private fun initTextWatcher() {
textWatcher = object : TextWatcher {
override fun afterTextChanged(s: Editable?) {}
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
masker?.onTextChanged(s, start, count, before)
}
}
addTextChangedListener(textWatcher)
}
And this is how I set my text manually;
private fun setEditTextWithoutTriggerListener(newText: String) {
removeTextChangedListener(textWatcher)
onTextChangedListener?.invoke(newText) // This is a custom listener.
setText(newText)
setSelection(text?.length ?: 0) // This puts cursor at the end of the text.
addTextChangedListener(textWatcher)
}
To handle hint position like TextInputEditText does, I simply copied it's functions into mine.
override fun getHint(): CharSequence? {
val layoutHint = getTextInputLayout()?.hint
return layoutHint ?: super.getHint()
}
override fun onCreateInputConnection(outAttrs: EditorInfo): InputConnection? {
val ic = super.onCreateInputConnection(outAttrs)
if (ic != null && outAttrs.hintText == null) {
outAttrs.hintText = getHintFromLayout()
}
return ic
}
private fun getTextInputLayout(): TextInputLayout? {
var parent = this.parent
while (parent is View) {
if (parent is TextInputLayout) {
return parent
}
parent = parent.getParent()
}
return null
}
private fun getHintFromLayout(): CharSequence? {
val layout = getTextInputLayout()
return layout?.hint
}
And my class extends AppCompatEditText like TextInputEditText does.
If you are calling addTextChangedListener() from onCreate() or init() move the call into onResume() or any other function called later, otherwise onTextChanged() is triggered before the resume
I have two edit text in my fragment where users can enter their age and weight. Based on age and weight I calculate how much water user should drink
When I try to call hide keyboard function on afterTextChanged, the keyboard gets hidden after user typed her first character.
How can I hide the keyboard when user actually finished typing?
P.S: there is a maxLength in my edit text 2 for age and 3 for weight, maybe this could be useful information when you are thinking about your recommendation
My code for edit texts with onChange extension function
//change listener extension for TextInputEditText
fun TextInputEditText.onChange(cb: (String) -> Unit) {
this.addTextChangedListener(object : TextWatcher {
override fun afterTextChanged(s: Editable?) {
cb(s.toString())
hideKeyboard()
}
override fun beforeTextChanged(
s: CharSequence?,
start: Int,
count: Int,
after: Int
) {
}
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
}
})
}
// change listener is called with agehandler function with user type age
// I check if the edit text is empty or not
binding.ageEditText.onChange {
if (binding.ageEditText.text.isNullOrEmpty()) {
Snackbar.make(binding.root, "Please type your age", Snackbar.LENGTH_SHORT).show()
} else dashboardViewModel.ageHandler(it)
}
fun hideKeyboard() {
val imm = activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view!!.windowToken, 0)
}
This may not be the cleanest way in the world to do things but I use a function to hide the keyboard when users press outside of the edit text. You could also look into hiding upon hitting the enter or submit key on the keyboard here
Otherwise to use these you would just say
editText.hideKeyBoardOnPressAway()
editText.addCharacterMax(2)
fun View.hideKeyBoardOnPressAway(){
this.onFocusChangeListener = keyboardHider
}
private val keyboardHider = View.OnFocusChangeListener { view, b ->
if (!b) { hideKeyboardFrom(view) }
}
private fun hideKeyboardFrom(view: View) {
val imm = view.context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
fun EditText.addCharacterMax(max: Int){
filters = arrayOf(InputFilter.LengthFilter(max))
}
I'm trying to write a simple Android app in Kotlin. I have an EditText and a Button in my layout. After writing in the edit field and clicking on the Button, I want to hide the virtual keyboard.
There is a popular question Close/hide the Android Soft Keyboard about doing it in Java, but as far as I understand, there should be an alternative version for Kotlin. How should I do it?
Use the following utility functions within your Activities, Fragments to hide the soft keyboard.
(*)Update for the latest Kotlin version
fun Fragment.hideKeyboard() {
view?.let { activity?.hideKeyboard(it) }
}
fun Activity.hideKeyboard() {
hideKeyboard(currentFocus ?: View(this))
}
fun Context.hideKeyboard(view: View) {
val inputMethodManager = getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
}
This will close the keyboard regardless of your code either in dialog fragment and/or activity etc.
Usage in Activity/Fragment:
hideKeyboard()
I think we can improve Viktor's answer a little. Based on it always being attached to a View, there will be context, and if there is context then there is InputMethodManager:
fun View.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
}
In this case the context automatically means the context of the view.
What do you think?
Simply override this method in your activity. It will automatically works in its child fragments as well.....
In JAVA
#Override
public boolean dispatchTouchEvent(MotionEvent ev) {
if (getCurrentFocus() != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
return super.dispatchTouchEvent(ev);
}
In Kotlin
override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
if (currentFocus != null) {
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(currentFocus!!.windowToken, 0)
}
return super.dispatchTouchEvent(ev)
}
In your Activity or Fragment create a function as:
fun View.hideKeyboard() {
val inputManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputManager.hideSoftInputFromWindow(windowToken, 0)
}
suppose you have a button with an id your_button_id in XML file related to this Activity or Fragment, so, on button click event:
your_button_id.setOnClickListener{
it.hideKeyboard()
}
Peter's solution solves neatly the problem by extending functionality of View class. Alternative approach could be to extend functionality of Activity class and thus bind operation of hiding keyboard with View's container rather than View itself.
fun Activity.hideKeyboard() {
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(findViewById(android.R.id.content).getWindowToken(), 0);
}
I didn't see this variant of Kotlin extension function:
fun View.hideSoftInput() {
val inputMethodManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
}
Its benefit is that this extension function could be called from every CustomView and in every click or touch listener
Make an object class named Utils:
object Utils {
fun hideSoftKeyBoard(context: Context, view: View) {
try {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm?.hideSoftInputFromWindow(view.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
} catch (e: Exception) {
// TODO: handle exception
e.printStackTrace()
}
}
}
You can use this method in any class where you want to hide the soft input keyboard. I am using this in my BaseActivity.
Here the view is any view that you use in your layout:
Utils.hideSoftKeyBoard(this#BaseActivity, view )
You can use Anko to make life easier, so the line would be:
inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
or maybe better to create extension function:
fun View.hideKeyboard(inputMethodManager: InputMethodManager) {
inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
}
and call it like this:
view?.hideKeyboard(activity.inputMethodManager)
Although there are many answers but this answer is related to a best practice in KOTLIN by opening and closing the keyboard with life cycle and extension function.
1). Create Extension Functions create a file EditTextExtension.kt and paste the below code
fun EditText.showKeyboard(
) {
requestFocus()
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as
InputMethodManager
imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}
fun EditText.hideKeyboard(
) {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as
InputMethodManager
imm.hideSoftInputFromWindow(this.windowToken, 0)
}
2). Create LifeCycleObserver Class Create a class EditTextKeyboardLifecycleObserver.kt and paste the code below
class EditTextKeyboardLifecycleObserver(
private val editText: WeakReference<EditText>
) :
LifecycleObserver {
#OnLifecycleEvent(
Lifecycle.Event.ON_RESUME
)
fun openKeyboard() {
editText.get()?.postDelayed({ editText.get()?.showKeyboard() }, 50)
}
fun hideKeyboard() {
editText.get()?.postDelayed({ editText.get()?.hideKeyboard() }, 50)
}
}
3). Then use the below code in onViewCreated / onCreateView
lifecycle.addObserver(
EditTextKeyboardLifecycleObserver(
WeakReference(mEditText) //mEditText is the object(EditText)
)
)
The Keyboard will open when the user opens the fragment or activity.
if you occur any problems, following the solution feel free to ask in the comment.
Here is my solution in Kotlin for Fragment. Place it inside setOnClickListener of the button.
val imm = context?.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager?
imm?.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0)
I found the answer that worked for me here: http://programminget.blogspot.com/2017/08/how-to-close-android-soft-keyboard.html
val inputManager:InputMethodManager = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputManager.hideSoftInputFromWindow(currentFocus.windowToken, InputMethodManager.SHOW_FORCED)
This works well with API 26.
val view: View = if (currentFocus == null) View(this) else currentFocus
val inputMethodManager = getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
Write a function to hide the keyboard:
private fun hideKeyboard(){
// since our app extends AppCompatActivity, it has access to context
val imm=getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
// we have to tell hide the keyboard from what. inorder to do is we have to pass window token
// all of our views,like message, name, button have access to same window token. since u have button
imm.hideSoftInputFromWindow(button.windowToken, 0)
// if you are using binding object
// imm.hideSoftInputFromWindow(binding.button.windowToken,0)
}
You have to call this function whereever u need
Thanks to #Zeeshan Ayaz
Here is a little improved version
Because 'currentFocus' is nullable we better check it using Kotlin's ?.let
override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
currentFocus?.let { currFocus ->
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(currFocus.windowToken, 0)
}
return super.dispatchTouchEvent(ev)
}
You can use from bellow code, I write bellow code in my fragment:
private val myLayout = ViewTreeObserver.OnGlobalLayoutListener {
yourTextView.isCursorVisible = KeyboardTool.isSoftKeyboardShown(myRelativeLayout.rootView)
}
Then in onViewCreated of fragment:
......
super.onViewCreated(view, savedInstanceState)
myRelativeLayout.viewTreeObserver.addOnGlobalLayoutListener(myLayout)
......
And in onDestroyView use too:
override fun onDestroyView() {
super.onDestroyView()
myRelativeLayout.viewTreeObserver.removeOnGlobalLayoutListener(myLayout)
}
And:
object KeyboardTool {
fun isSoftKeyboardShown(rootView: View): Boolean {
val softKeyboardHeight = 100
val rect = Rect()
rootView.getWindowVisibleDisplayFrame(rect)
val dm = rootView.resources.displayMetrics
val heightDiff = rootView.bottom - rect.bottom
return heightDiff > softKeyboardHeight * dm.density
}
}
Kotlin
I use bellow code:
import splitties.systemservices.inputMethodManager
inputMethodManager.hideSoftInputFromWindow(view?.windowToken, 0)
You can use a Function Extension in Kotlin. Replace activity by fragment if you need make it in Fragment.
fun Activity.hideKeyboard() {
hideKeyboard(currentFocus ?: View(this))
}
Hello I frequently use these two extension functions for showing and hiding soft keyword.
Show Soft Keyboard
fun Any.showSoftKeyboard(view: View, context: Context) {
if (view.requestFocus()) {
val imm: InputMethodManager =
context.getSystemService(Context.INPUT_METHOD_SERVICE) as
InputMethodManager
imm.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}
}
Hide Soft Keyboard
fun Any.hideSoftKeyboard(view: View, context: Context) {
val imm =
context.getSystemService(Context.INPUT_METHOD_SERVICE) as
InputMethodManager
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
You can use these methods in any Object Class to access these globally or you can make separate Extensions/CommonUtils Files for these.
I have a RecyclerView that contains EditText child elements. I would like to hide the soft keyboard when the selected EditText is scrolled off screen. How can I tell when the EditText is no longer on screen? Is there some event listener that I can attach to the EditText element to tell?
Implement onTouchListener like this:
yourRecycleView.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
return false;
}
});
This is what worked for me : I used RecyclerView.OnScrollListener with PublishRelay for debouncing events.
class RecyclerViewActivity : Activity(){
...
private val scrollableRelay = PublishRelay.create<Unit>()
private val disposable = CompositeDisposable()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
recyclerView.addOnScrollListener(object: RecyclerView.OnScrollListener(){
override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
scrollableRelay.accept(Unit)
}
})
scrollableRelay
.debounce(100, TimeUnit.MILLISECONDS)
.subscribe({
if (currentFocus == recyclerView) {
hideKeyboard()
}
})
.addTo(disposable)
}
override fun onDestroy() {
disposable.onDestroy()
}
}
Once the view is scrolled from the screen the focus goes up to recyclerView.
So, we can implement this functionality using RecyclerView.OnScrollListener.
onScrolled tracks even slightest scroll of the view. That's why we need to add debounce that we'll not receive a lot of events.
hideKeyboard and addTo are extension functions:
fun Disposable.addTo(compositeDisposable: CompositeDisposable) {
compositeDisposable.add(this)
}
fun Activity.hideKeyboard() =
currentFocus?.let {
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(it.windowToken, 0)
}
yourRecycleView.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
edittext.clearFocus(); //hidden keyboard
return false;
}
});
My solution:
editText.setOnFocusChangeListener((v, hasFocus) -> {
Handler handler = new Handler();
if (!hasFocus) {
handler.postDelayed(() -> {
if (!editText.hasFocus()) {
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, 0);
}
}, 200);
}
});
Kotlin solution that dismisses the keyboard when:
the focused View is scrolled off the RecyclerView
or if the user presses the Enter key, and the OS was unable to find something to focus on that is inside the RecyclerView...
// dismiss the keyboard when it is no longer focusing on anything inside the recyclerview
recyclerView.viewTreeObserver.addOnGlobalFocusChangeListener { _, newFocus: View? ->
if (newFocus == recyclerView || recyclerView !in (newFocus?.ancestors ?: emptySequence())) {
recyclerView.context.inputService.hideSoftInputFromWindow(recyclerView.windowToken, 0)
}
}
val Context.inputService get() = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val View.ancestors: Sequence<View> get() = generateSequence(this) { it.parent as? View }
Been facing the same issue in BottomSheet . Took me a while to realize that to get currentFocus i have to use dialog.currentFocus instead of activity.currentFocus . Below is my Solution maybe it helps someone .
binding.recyclerView.addOnScrollListener(object:RecyclerView.OnScrollListener(){
override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
super.onScrollStateChanged(recyclerView, newState)
if (newState == RecyclerView.SCROLL_STATE_IDLE) {
dialog?.currentFocus?.let {
if(it is RecyclerView){
val imm = requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(it.windowToken, 0)
}
}
}
}
})
