我试图弄清楚如何设置我的代码,以便在组合框中选择一个选项时,它也会更改标签的文本。根据我的理解,它涉及一个叫做项目监听器的东西,但我们没有在课堂上讨论过这个问题。我们最近讨论了继承和接口,但我不知道这将如何应用。

//this event is fired whenever user selects or change a item from combobox
private void comboBox1_SelectionChangeCommitted(object sender, EventArgs e)
{
//do whatever you want to do in this
}
for android do this
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// your code here
}
@Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
});
