在我的 android 应用程序（几乎完成）中，我有一个列表视图来显示作弊码的名称，当用户单击名称时，我希望文本更改
例如：
之前 - 点击我
之后 - 你点击我
我不确定是否我这样做是正确的，如果 OnClick 弹出窗口更容易，任何链接或评论/答案都会受到高度评价

谷歌寻找以下关键字，但结果没有给我我正在寻找的东西

“Android Listview”、“Android Listview popup”、“Android Listview Onclick”、“Listview Onclick”、“点击时改变android应用文本”、“点击时改变android listview结果”

作弊码.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"

<TextView
android:layout_width="fill_parent"

            Toast.makeText(getApplicationContext(),

        }
    });

在 onItemClick 中试试这个：

CharSequence text= (CharSequence) parent.getItemAtPosition(pos);
//This is where you change the text to show
text = "You " + text;
Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
//If you want to update the listview
Cheatcodes[pos] = text;
