android xml:未能解析文件,无法解析android的XML文件

我基本上是全新的,并在书中通过一个例子.

我的button1.xml看起来像这样….

android:drawable="@drawable/buttonpressed" />

android:drawable="@drawable/buttonfocused" />

main.xml中…

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/button_one"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:paddingTop="5px"

android:src="@drawable/button1">

而且我一直收到这个错误

eclipse.buildId=M20110909-1335

java.vendor=Oracle Corporation

BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US

我似乎无法弄清楚这一点.我搜索并发现了许多类似的问题,但自己没有发现任何错误.有什么建议？

– 我确实尝试切换两个文件(按下按钮和按钮),但仍然在同一行代码中收到错误.然后用ic_launcher文件替换了所有文件,这也导致了同样的错误.如果我设置android.src =“#00000000”它确实有效.我不知道这是否有帮助,但似乎表明问题不是文件,而是在button1.xml代码中.

所以我认为我已经修好了.我不确定我做了什么,但重新输入了

机器人：SRC = “@绘制/ button1的” >

线.它有效.谢谢你们的帮助！
