Qpython3和androidhelper，droid.dialogSetSingleChoiceItems

Question

我正在尝试找出androidhelper，我发现它对python3和Android非常有用。我正在尝试使用dialogSetChoiceItems从列表中返回一个选择。我已经设置好了，并且我已经尝试了各种方法。我将得到一些返回值，但它是列表的长度。任何帮助都将不胜感激。谢谢,

import androidhelper
droid = androidhelper.Android()

def test_alert_dialog_with_single_choice_list(Title, ListOfStuff):

  droid.dialogCreateAlert(Title)
  droid.dialogSetSingleChoiceItems(ListOfStuff)

  droid.dialogSetPositiveButtonText('Select')
  droid.dialogShow()
  response = droid.dialogGetSelectedItems().result
  return response





if __name__ == '__main__':

    Listy = [1,2,3,4,5,6,7,8]
    YTitle = 'Title of The Thing'

    FReturn = test_alert_dialog_with_single_choice_list(YTitle, Listy)

    print(FReturn)

这个例子用"xyz“按钮和"abcde”项创建一个对话框，然后是print(pressed_button, selected_items_indexes)，makeToast你按下的按钮和选中的项。试试看！它在我的手机上工作得很好，如果不能在你的手机上工作，请告诉我。

def mydialog(title,buttons=["OK"],items=[],multi=False):
    title = str(title)
    droid.dialogCreateAlert(title)
    if len(items) > 0:
        if multi:
            droid.dialogSetMultiChoiceItems(items)
        else:
            droid.dialogSetSingleChoiceItems(items)
    if len(buttons) >= 1:
        droid.dialogSetPositiveButtonText(buttons[0])
    if len(buttons) >= 2:
        droid.dialogSetNeutralButtonText(buttons[1])
    if len(buttons) >= 3:
        droid.dialogSetNegativeButtonText(buttons[2])
    droid.dialogShow()
    res0 = droid.dialogGetResponse().result
    res = droid.dialogGetSelectedItems().result
    if "which" in res0.keys():
        res0={"positive":0,"neutral":1,"negative":2}[res0["which"]]
    else:
        res0=-1
    return res0,res
items = [i for i in "abcde"]
btns = [i for i in "xyz"]
pressed_button, selected_items_indexes = mydialog("Dialog test!", btns, items, True)
print(pressed_button, selected_items_indexes)
if pressed_button == -1:
    droid.makeToast("You didn't press any buttons!")
else:
    droid.makeToast("You pressed %s!"%("xyz"[pressed_button]))
if selected_items_indexes == []:
    droid.makeToast("You selected nothing!")
else:
    selected_abc = "".join(["abcde"[i] for i in selected_items_indexes])
    droid.makeToast("You selected %s!"%selected_abc)
