9.12 AddEditFragment Class 373
9.12.6 View.OnClickListener saveContactButtonClicked and
Method saveContact
When the user touches this Fragment’s FloatingActionButton, the saveContactButton-
Clicked listener (Fig. 9.45, lines 152–162) executes. Method onClick hides the keyboard
(lines 157–159), then calls method saveContact.
151 // responds to event generated when user saves a contact
152 private final View.OnClickListener saveContactButtonClicked =
153 new View.OnClickListener() {
154 @Override
155 public void onClick(View v) {
156 // hide the virtual keyboard
157 ((InputMethodManager) getActivity().getSystemService(
158 Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(
159 getView().getWindowToken(), 0);
160 saveContact(); // save contact to the database
161 }
162 };
163
164 // saves contact information to the database
165 private void saveContact() {
166 // create ContentValues object containing contact's key-value pairs
167 ContentValues contentValues = new ContentValues();
168 contentValues.put(Contact.COLUMN_NAME,
169 nameTextInputLayout.getEditText().getText().toString());
170 contentValues.put(Contact.COLUMN_PHONE,
171 phoneTextInputLayout.getEditText().getText().toString());
172 contentValues.put(Contact.COLUMN_EMAIL,
