我正在开发一个需要片段的项目。每当我测试运行项目时,在我的fragment类中,我得到一个异常,指向我的oncreateview方法的inflaterline,如下所示。
Process: com.example.joey.maranathahealthblog, PID: 29380
android.view.InflateException: Binary XML file line #12: Error inflating class <unknown>
at android.view.LayoutInflater.createView(LayoutInflater.java:633)
at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:743)
at android.view.LayoutInflater.rInflate(LayoutInflater.java:806)
at android.view.LayoutInflater.inflate(LayoutInflater.java:504)
at android.view.LayoutInflater.inflate(LayoutInflater.java:414)
at com.example.joey.maranathahealthblog.BlogTabs.TabsFragments.HygieneClone.onCreateView(HygieneClone.java:27)
这是我的片段类的片段
public class HygieneClone extends Fragment {
public HygieneClone() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
// error occurs here
return inflater.inflate(R.layout.fragment_hygiene_clone, container, false);
}
}
我的布局文件如下所示:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.joey.maranathahealthblog.BlogTabs.TabsFragments.HygieneClone">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/hygiene_recyclerView"/>
<android.support.design.widget.FloatingActionButton
android:id="@+id/newPost_Fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="@color/colorPrimary"
android:src="@drawable/ic_add_black_24dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginRight="20dp"
android:layout_marginBottom="40dp"/>
由于此异常,应用甚至无法加载第一个屏幕,因此可能导致此问题。
答案 0 :(得分:0)
因为您没有与android.support.design.widget.FloatingActionButton相关的依赖项。 尝试添加 - 编译&#39; com.android.support:design:23.2.0&#39; 在build.gradle中
