錯誤：android.view.InflateException：二進制XML文件行＃9：錯誤充氣類片段

Question

我創建了一個活動與2 seprat 片段。在運行時間錯誤是這些：

下面是代碼：

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

    <fragment  
     android:name="com.example.lesson1.Fragment1" 
     android:id="@+id/activity_fragment1" 
     android:layout_weight="1" 
     android:layout_width="0px" 
     android:layout_height="match_parent" 
    /> 

    <fragment 
     android:name="com.example.lesson1.Fragment2" 
     android:id="@+id/activity_fragment2" 
     android:layout_weight="1" 
     android:layout_width="0px" 
     android:layout_height="match_parent" 
    /> 


</LinearLayout> 

public class Myfragments extends Activity 
{ 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 

     super.onCreate(savedInstanceState); 

     setContentView(R.layout.activity_myfragments); 

    } 
} 

的錯誤是：

Answer 1

my adds are import 'android.support.v4.app.Fragment

您延長正常活動。所以你需要使用import android.app.Fragment。

如果您要使用支持庫中的片段，然後擴展FragmentActivity並使用import android.support.v4.app.Fragment。

Fragment Activity是SupportBased Fragments的基類。
