Android 活性大的片段

我从这个链接（）下载了这个基本片段的示例！它非常完美，在平板电脑上比在手机上更有效。但当我在另一个项目上实施的那一刻，电话就响了。。。当它应该在大屏幕上打开xml文件时，应用程序将在启动时崩溃！解决？我丢了什么？谢谢大家!

java.lang.RuntimeException: Unable to start activity    ComponentInfo{com.chiari.nicola.myapplication/com.chiari.nicola.myapplication.MainActivity_list}: android.view.InflateException: Binary XML file line #23: Error inflating class fragment

程序包名称错误。 检查您的类HeadlinesFragment所在的包

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">

<fragment android:name="com.chiari.nicola.myapplication.HeadlinesFragment"
      android:id="@+id/headlines_fragment"
      android:layout_weight="1"
      android:layout_width="0dp"
      android:layout_height="match_parent" />

   <fragment android:name="com.chiari.nicola.myapplication.ArticleFragment"
      android:id="@+id/article_fragment"
      android:layout_weight="2"
      android:layout_width="0dp"
      android:layout_height="match_parent" />

</LinearLayout>

---

您给xml提供了错误的包名引用。根据错误，您的包名为

com.chiari.nicola.myapplication

因此，在xml中，您给出了

com.example.android.fragments

。您需要将其设置为包名。您的

large.xml

应该如下所示

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">

<fragment android:name="com.chiari.nicola.myapplication.HeadlinesFragment"
      android:id="@+id/headlines_fragment"
      android:layout_weight="1"
      android:layout_width="0dp"
      android:layout_height="match_parent" />

   <fragment android:name="com.chiari.nicola.myapplication.ArticleFragment"
      android:id="@+id/article_fragment"
      android:layout_weight="2"
      android:layout_width="0dp"
      android:layout_height="match_parent" />

</LinearLayout>

二进制XML文件行#23：错误膨胀类片段

首先在下面显示xmlcheck答案。我现在发现了我的错误！我在大型xml文件中更改了pacchetto的名称。。。。但是这个应用程序崩溃了。。。对于另一个错误…java.lang.IllegalArgumentException:DrumerLayout必须使用MeasureSpec.Exact进行测量。

com.chiari.nicola.myapplication
