Null pointer error with hideSoftInputFromWindow

Question

I get a null pointer exception at this row:

public void hideKeyboard(){ 
InputMethodManager inputManager = (InputMethodManager)            
            this.         


        

Answer 1

I had the same issue where getCurrentFocus() was returning null. So this method worked for me, and I would just call it on my onClick to hide the keyboard if its shown or still not throw a null pointer exception even if the keyboard was not shown:

public void hiddenInputMethod() {

    InputMethodManager imm = (InputMethodManager) getSystemService(MyActivity.this.INPUT_METHOD_SERVICE);
    if (getCurrentFocus() != null)
        imm.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
