Adaptateur de vrille personnalisé (ArrayAdapter)
public class SpinAdapter extends ArrayAdapter<User>{
// Your sent context
private Context context;
// Your custom values for the spinner (User)
private User[] values;
public SpinAdapter(Context context, int textViewResourceId,
User[] values) {
super(context, textViewResourceId, values);
this.context = context;
this.values = values;
}
@Override
public int getCount(){
return values.length;
}
@Override
public User getItem(int position){
return values[position];
}
@Override
public long getItemId(int position){
return position;
}
// And the "magic" goes here
// This is for the "passive" state of the spinner
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// I created a dynamic TextView here, but you can reference your own custom layout for each spinner item
TextView label = (TextView) super.getView(position, convertView, parent);
label.setTextColor(Color.BLACK);
// Then you can get the current item using the values array (Users array) and the current position
// You can NOW reference each method you has created in your bean object (User class)
label.setText(values[position].getName());
// And finally return your dynamic (or custom) view for each spinner item
return label;
}
// And here is when the "chooser" is popped up
// Normally is the same view, but you can customize it if you want
@Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
TextView label = (TextView) super.getDropDownView(position, convertView, parent);
label.setTextColor(Color.BLACK);
label.setText(values[position].getName());
return label;
}
}
Et la mise en œuvre :
public class Main extends Activity {
// You spinner view
private Spinner mySpinner;
// Custom Spinner adapter (ArrayAdapter<User>)
// You can define as a private to use it in the all class
// This is the object that is going to do the "magic"
private SpinAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Create the Users array
// You can get this retrieving from an external source
User[] users = new User[2];
users[0] = new User();
users[0].setId(1);
users[0].setName("Joaquin");
users[1] = new User();
users[1].setId(2);
users[1].setName("Alberto");
// Initialize the adapter sending the current context
// Send the simple_spinner_item layout
// And finally send the Users array (Your data)
adapter = new SpinAdapter(Main.this,
android.R.layout.simple_spinner_item,
users);
mySpinner = (Spinner) findViewById(R.id.miSpinner);
mySpinner.setAdapter(adapter); // Set the custom adapter to the spinner
// You can create an anonymous listener to handle the event when is selected an spinner item
mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view,
int position, long id) {
// Here you get the current item (a User object) that is selected by its position
User user = adapter.getItem(position);
// Here you can do the action you want to...
Toast.makeText(Main.this, "ID: " + user.getId() + "\nName: " + user.getName(),
Toast.LENGTH_SHORT).show();
}
@Override
public void onNothingSelected(AdapterView<?> adapter) { }
});
}
}
