keyboard是另外一个xml中的布局, 在视图中能正常显示.
然后在代码中:
-
stub = (ViewStub)findViewById(R.id.keyboardStub);
-
stub.inflate();
程序执行到 stub.inflate(); 报错 "ViewStub must have a valid layoutResource". 检查了半天,
才发现是在主xml中设置时使用了<include>标签的用法:
-
layout="@layout/keyboard"
正确的应该是:
-
android:layout="@layout/keyboard"
修改后, 执行正常!
