Null pointer error with hideSoftInputFromWindow

Question

I get a null pointer exception at this row:

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


        

Answer 1

Just use this one:

public void hideKeyboard(View v){ 
  InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
