You get a ClassCastException at this line:
这里有一个ClassCastException:
txtMessage = (EditText) findViewById(R.id.invite_text);
That means the View object with the id R.id.invite_text is not EditText. However this is not true since invite_text is indeed of type EditText.
这意味着具有id R.id的视图对象。EditText invite_text不是。然而，这不是真的，因为invite_text实际上是EditText类型。
<EditText
android:id="@+id/invite_text"
android:layout_width="fill_parent"
...
" />
So I think your resource file is not up to date. The code looks all right. Delete your gen folder and run it again. Your resource file should be recreated when you delete gen folder.
所以我认为你的资源文件不最新。代码看起来没问题。删除gen文件夹并再次运行它。当您删除gen文件夹时，您的资源文件应该被重新创建。
