我在一个活动上有两个列表视图，一切正常，但如果我想从listview 1和listview 2获取点击的项目，我只能从listview 1中获取项目
activity_smokes：
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

修改 我更新了代码，它现在正在为我工作！
答案 0 :(得分：0)
原因是您使用不同的数据集来填充列表视图，但在#import random module
import random
#main function
def main():
#program message
print("Rock, Paper, Scissors Game")
#initializing variables that would hold choices of user and computer
comp = 1
user = 1
while comp == user:
print("Enter your choice in range from 1 to 3")
#prompt user to enter choice
user = int(input("Your choice: "))
#randomly assign choice to computer
comp = random.randint(1,3)
#display choice of computer
print("Computer Choice : ",comp)
#display game drawn message, when same choices
if (comp == user):
print("Game Drawn. Select again")
#calling function to decide winner
winner (comp, user)
#winner function
def winner(comp, user):
#rock and scissor choice
if(comp == 1 and user ==3):
print("Computer win")
print("The rock smashes scissor")
elif(comp == 3 and user ==1):
print("User win")
print("The rock smashes scissor")
else:
#paper and rock choice
if(comp == 1 and user == 2):
print("User win")
print("The paper wraps rock")
elif (comp == 2 and user ==1):
print("Computer win")
print("Scissors cut paper")
elif (comp == 2 and user == 3):
print("User win")
print("Scissors cut paper")
else:
print("Invalid selection")
#calling main function
main()
中，您只从一个数据集中获取数据，尽管您从任何列表视图中选择了一个项目。
First List使用“CustomListViewValuesArrCT”数据集
onItemClick第二个列表使用“CustomListViewValuesArr”数据集
ListView listCT = (ListView)findViewById(R.id.listView);
adapterCT=new CustomAdapter(CustomListView, CustomListViewValuesArrCT,res);
listCT.setAdapter( adapterCT);
<强> BUT 仅在列表项选择中从“CustomListViewValuesArr”获取数据。
ListView list= ( ListView )findViewById( R.id.listView1 );
adapter=new CustomAdapter( CustomListView, CustomListViewValuesArr,res );
list.setAdapter(adapter);
您需要修复流程，以便在单击列表项后，从该数据集中获取数据，使用该数据集为该特定列表设置适配器。
