Hide keyboard when navigating from a fragment to another

Kotlin

For Kotlin, you can use this as a top level function, just add the code to a separate class such as Utils.kt.

fun hideKeyboard(activity: Activity) {
    val inputMethodManager =
        activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

    // Check if no view has focus
    val currentFocusedView = activity.currentFocus
    currentFocusedView?.let {
        inputMethodManager.hideSoftInputFromWindow(
            currentFocusedView.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
    }
}

To access it from Fragment, call it like:

hideKeyboard(activity as YourActivity)

Thanks to Silvia H for Java code.

Put the code that hides the keyboard in your "save button" click listener, and use this method to hide the keyboard:

    public static void hideKeyboard(Activity activity) {
        InputMethodManager inputManager = (InputMethodManager) activity
        .getSystemService(Context.INPUT_METHOD_SERVICE);

        // check if no view has focus:
         View currentFocusedView = activity.getCurrentFocus();
         if (currentFocusedView != null) {
             inputManager.hideSoftInputFromWindow(currentFocusedView.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
         }
     }

Easiest way to hide keyboard in fragment or Activity

Soluton : 1

//hide keyboard
public static void hideKeyboard(Context ctx) {
    InputMethodManager inputManager = (InputMethodManager) ctx
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    // check if no view has focus:
    View v = ((Activity) ctx).getCurrentFocus();
    if (v == null)
        return;

    inputManager.hideSoftInputFromWindow(v.getWindowToken(), 0);
}

Solution : 2

    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
