InputMethodManager imm=(InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
//Find the currently focused view, so we can grab the correct window token from it.
View view3=getCurrentFocus();
//If no view currently has focus, create a new one, just so we can grab a window token from it
