Question

在我的Android应用程序中（差不多完成）我有一个列表视图来显示作弊代码的名称，当用户点击我希望文本更改的名称时例如：
之前 - 点击我
在你点击我之后我不确定我是否正确行事，如果OnClick弹出窗口更容易，任何链接或评论/答案都会非常受欢迎

谷歌寻找以下关键词，但结果并没有给我我想要的东西

“Android Listview”，“Android Listview弹出窗口”，“Android Listview Onclick”，“Listview Onclick”，“单击时更改Android应用程序文本”，“单击时更改Android列表视图结果”

                int position, long id) {
            // When clicked, show a toast with the TextView text
            Toast.makeText(getApplicationContext(),
            ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
        }
    });

}

}

Answer 1

在onItemClick中尝试这个：

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;
