Screen goes dimmed when try to hide keyboard

fun Activity.hideKeyboard() {
if (currentFocus != null) {
val inputMethodManager =
getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(currentFocus!!.windowToken, 0)
}
}
I use this function to hide keyboard when user press enter in keyboard. But the screen often goes dimmed. I also use this code in other screen but the screen not goes dimmed. How to prevent it?

This is the video. When i press enter, keyboard gone and background color got dimmed. Then i click the edit text again, and screen back to bright

I can't reproduce your problem without your activity/fragment code so these are just some guesses
Try this code for hiding your keyboard:
public static void hideKeyboard(Activity activity) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
//Find the currently focused view, so we can grab the correct window token from it.
View view = activity.getCurrentFocus();
//If no view currently has focus, create a new one, just so we can grab a window token from it
if (view == null) {
view = new View(activity);
}
if (imm != null) {
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
After hiding the keyboard, try requesting focus for your EditText:
edittext.requestFocus()
We are trying to emulate user click to gain back focus to EditText to prevent screen dimming.
Also try calling this function after a little delay (using handler). sometimes that does the job.
If this doesn't resolve the issue then something is probably wrong in your activity/fragment and you must share your activity code.

How to hide keyboard after edittext click

I have a edittext in my android app where I can put a person birthdate. When I click on it a dialog fragment appears, but I have to click two times. After first click there is an keyboard and I don't want it.
I know that I can use button instead, but i prefer editext, because it looks better :)
How can I change it? Can I open diagram in first edittext click? Thanks in advance!

You can make your EditText not focusable by adding android:focusable="false" in XML declaration and then use simple onClickListener on the EditText.
Else, you can also use the following method to hide the keyboard:
public void hideSoftKeyBoard(Activity activity) {
// Check if no view has focus:
View view = activity.getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
This can be invoked as follows:
hideSoftKeyBoard(this) from an activity or hideSoftKeyBoard(getActivity()) from a fragment.
Hope this helps!

Keyboard not closing when dismiss the dialogFragment

I have a fragment which i use to show map. From this fragment I am opening another dialog fragment which have an editText. On clicking editText the keyboard opens but when I dismiss the dialogFragment without first closing the keyboard, the dialogFragment closes as it should but the keyboard remains open. and after again touching anywhere the keyboard closes. How do I close the keyboard on dismissing the dialogFragment.
I have already tried :
android:windowSoftInputMode="stateAlwaysHidden" in activity.
also tried :
InputMethodManager imm =
(InputMethodManager) messageEditTxt.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isActive())
imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
in onDismiss function.

Try this
public static void hideSoftKeyboard(Context context, View view) {
try {
InputMethodManager inputMethodManager =
(InputMethodManager) context.getSystemService(
Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(
view.getWindowToken(), 0);
} catch (Exception e) {
e.printStackTrace();
}
}
Usage
hideSoftKeyboard(getActivity(), getView())

I had the same problem and found that it is related to the windowSoftInput defined in the manifest. After removing android:windowSoftInputMode="stateHidden" from the activity, it worked.

Just place this in your global class and you can access anywhere
public static void hideKeyboard(Activity activity) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
//Find the currently focused view, so we can grab the correct window token from it.
View view = activity.getCurrentFocus();
//If no view currently has focus, create a new one, just so we can grab a window token from it
if (view == null) {
view = new View(activity);
}
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
for Activity-:
GlobalClass.hideSoftKeyborad(MainActivity.this);
for fragments-
GlobalClass.hideSoftKeyborad(getActivity);

How to close keyboard on any click event?

I have multiple edit text and button on screen, on every button click there are some validation if validation is successful then i have to hide keyboard. I have tried so many code but nothing work.
Currently i am using,
InputMethodManager imm = (InputMethodManager) cntx.getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.HIDE_NOT_ALWAYS, 0);
This is toggle, it opens if keyboard is hidden, but i wants to hide keyboard whether it is open or not.

Make one function like this, and Call from anywhere by passing context
like this :
public static void hideKeyBoard_WithView(Context context) {
// Check if no view has focus:
View view = ((Activity) context).getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
Hope it will help you ! :) just try !

edittext.setFocusable(true);
edittext.setFocusableInTouchMode(true);
//try using this.. make the parameter as false when u dont required the keyboard & write the onclick method on edit text & make parameters true to get the focus again

Get current focussed view and using that view window token hide your keyboard.
View view = this.getCurrentFocus(); // get current focussed edittext
if (view != null) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Hide softkeyboard on dialog box loading in Android 4.0

I have an activity which opens up a dialog that contains edittexts on a button click. As soon as the dialog opens the softkeyboard shows. I want to prevent this. Only when I click on the edittext in the dialog should the softkeyboard appear. I am using Android 4.
Thanks in advance

To achieve this, set the soft input mode just before you call dialog.Show():
// Build and create your dialog.
AlertDialog dialog = new AlertDialogBuilder(...).create();
// Hide soft keypad by default (will be displayed when user touches any edit field).
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
// Show the dialog.
dialog.show();

This should work is any case:
public void hideKeyboard() {
mActivity.runOnUiThread(new Runnable() {
public void run() {
InputMethodManager inputManager = (InputMethodManager) mActivity
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(mActivity
.getCurrentFocus().getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
}
});
}

adding this to your Manifest is all you hav to do:
android:windowSoftInputMode="stateHidden"
Simple, but in case someone was looking here
:)
