我已经在 android 中创建了一个应用程序，现在我已经创建了活动 notes.xml、contactinfo.xml 和一个名为 listplaceholder5.xml 的 android xml 文件，我需要在“listplaceholder5”中将 textview 的 android:text 更改为“notes” .xml”文件，它在note.java中使用，但它不显示“notes”，它显示“contact”。我试过sode a sbelow：请帮助我更改代码以便我可以解决它，

注意.xml

得到标题后如下：

title= (TextView) findViewById(R.id.item_title);

使用setText方法根据需要设置标题。我认为它会解决你的问题。
