用戶從android alertdialog檢查listview時如何獲取索引值

List<String> ShowView = new ArrayList<String>();
    final CharSequence[] Animals = ShowView.toArray(new String[ShowView.size()]);
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(TestActivity.this);
    dialogBuilder.setTitle("ListView");
    dialogBuilder.setItems(Animals, new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int item) {
                                //This get index value!!
                            }
                        });
                        AlertDialog alertDialogObject = dialogBuilder.create();
                        alertDialogObject.show();

Answer 1

您正在尋找DialogInterface.OnClickListener()給出的int item 。

Answer 2

整數項是單擊項的索引。

 final CharSequence[] Animals= ShowView.toArray(new String[ShowView.size()]);
    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
    builder.setTitle("ListView");
    builder.setItems(Animals, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
           String val=String.valueOf(Animals[item]);// this is value
        }
    });
    builder.show();
