Eclipse - Listview OnClick 弹出窗口

Question

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代码的名称，当用户单击我想要更改文本的名称时
例如：
之前 - 点击我
在你点击我之后
我不确定我这样做是否正确，如果 OnClick 弹出窗口会更容易，任何链接或 cmets/ 答案都会受到高度评价

google 寻找以下关键字，但结果没有给我我要找的东西

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

            Toast.makeText(getApplicationContext(),
            ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
        }
    });

}

}

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;
