问题
最近换了新机子,今天在静态用fragment时突然发现闪退,一看显示 Binary XML file line #12: Error inflating class fragment 错误
后面看了一下是没有写id 的问题。。。。之前写的时候貌似没这个问题啊。先记录下
错误提示如下

在网上看了一下还有两个地方需要注意:关于第二项需要了解两种包的不同,而且都是比较旧的东西,所以重新整理了一下
1.XML文件中引入的Fragment路径不对
```java
<fragment
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.example.dyleaf.myfragments.Fragments.Fragment1"> //这里包名一定要正确
</fragment>
2.在Activity继承Fragment时引入的包名不对
注意
android.support.v4.app.FragmentActivity和android.app.Fragment区别
3.0之前的Activity是不能用fragment的。为了能使用fragment(supportV4中),才有了FragmentActivity。FragmentActivity继承的Activity。
