A hint spinner that allows showing a hint, similar to the HTML Select <option value="">Select your option</option>
You can use either a default or a custom layout.
Add this dependency to your build.gradle file:
dependencies {
compile 'me.srodrigo:androidhintspinner:1.0.0'
}The HintSpinner class works as a container, binding a plain Android Spinner and a HintAdapter, which manages the hint. A callback is needed at the moment to skip the hint selected event, as otherwise it would have to be handled by the user (this might be optional in future versions).
All you need to do is to instantiate HintSpinner and call the init() method. This will automatically select the hint for you and bind the spinner to the adapter. You can select the hint again manually when you want, just calling the selectHint() method.
The HintAdapter class uses the default spinner layout by default and no extra configuration is required. You just need to instanciate the HintSpinner with the default layout constructor:
HintSpinner<String> hintSpinner = new HintSpinner<>(
yourAndroidSpinner,
// Default layout - You don't need to pass in any layout id, just your hint text and
// your list data
new HintAdapter<>(this, R.string.your_hint_text, yourStringsList),
new HintSpinner.Callback<String>() {
@Override
public void onItemSelected(int position, String itemAtPosition) {
// Here you handle the on item selected event (this skips the hint selected event)
}
});
hintSpinner.init();You can use whatever layout you want by overriding the HintAdapter#getCustomView() method. You can use any entity to store the data you want to show on your layout.
HintAdapter<User> hintAdapter = new HintAdapter<User>(
this,
R.layout.your_custom_layout,
R.string.your_hint_text,
usersList) {
@Override
protected View getCustomView(int position, View convertView, ViewGroup parent) {
final User user = getItem(position);
final String name = user.getName();
final String lastName = user.getLastName();
// Here you inflate the layout and set the value of your widgets
View view = inflateLayout(parent, false);
view.findViewById(R.id.user_image_view).setBackgroundResource(
R.drawable.ic_action_face_unlock);
((TextView) view.findViewById(R.id.user_name_text_view)).setText(name);
((TextView) view.findViewById(R.id.user_last_name_text_view)).setText(lastName);
return view;
}
}
HintSpinner<User> hintSpinner = new HintSpinner<>(
yourAndroidSpinner,
hintAdapter,
new HintSpinner.Callback<String>() {
@Override
public void onItemSelected(int position, String itemAtPosition) {
// Here you handle the on item selected event (this skips the hint selected event)
}
});
hintSpinner.init();** 1.0 ** Initial version.
