ListView in AlertDialog
提问by bugzy
I am using a ListView in an AlertDialog to display a list of items. When the user clicks on one of the items, I want the dialog to close. I would not have any action buttons on the dialog. Any ideas on how I would accomplish this?
我在 AlertDialog 中使用 ListView 来显示项目列表。当用户单击其中一项时，我希望关闭对话框。我不会在对话框上有任何操作按钮。关于我将如何实现这一目标的任何想法？

You should be able to do something like:
您应该能够执行以下操作：
final CharSequence[] items = {"Foo", "Bar", "Baz"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Make your selection");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
// Do something with the selection
}
});
AlertDialog alert = builder.create();
alert.show();
This pagehas some other examples of different types of Dialogs.
