Androidxml控件写法和findViewById的对应使用

1.xml控件示例

android:name&＃61;"&＃64;&＃43;id/ui_text_view"
android:layout_width&＃61;"wrap_content"
android:layout_height&＃61;"wrap_content"
android:text&＃61;"Hello World!" />

id名称是findviewbyid要寻找的对象&＃xff0c;命名严格&＃xff0c;书写方式一定要用 "&＃64;&＃43;id/xxxx"。只有这样&＃xff0c;才能在findviewbyid时被找到。

这个是基于android的标准hellowrold工程改写的。完整xml文件如下&＃xff1a;

    package&＃61;"io.vov.vitamio.demo"

    android:versionCode&＃61;"002"

    android:versionName&＃61;"0.0.2" >

        android:targetSdkVersion&＃61;"19" />

        android:label&＃61;"&＃64;string/vitamio_demo_name" >

            android:name&＃61;"io.vov.vitamio.activity.InitActivity"
