在Android上填充片段時出現的問題

Question

我想在我的主要活動中加載一個片段，稍後將成爲我的導航選項卡之一。問題是應用程序崩潰並且說片段不能被充氣。 我發現其他類似的問題，但沒有解決方案的能不能幫我

這裏是我的代碼

MainActivity.java

public class MainActivity extends FragmentActivity { 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    }  
} 

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.projecttabs.MainActivity"> 

    <fragment 
     android:id="@+id/fragment1" 
     android:name="com.example.projecttabs.FragmentAbout" 
     android:layout_width="match_parent" 
     android:layout_weight="1" 
     android:layout_height="0dp" /> 

</LinearLayout> 

FrgagmentAbout.ja VA

public class FragmentAbout extends Fragment { 

    public View OnCreateView(LayoutInflater l, ViewGroup v, Bundle savedInstanceState){ 

     return l.inflate(R.layout.fragment_about,v,false); 
    } 

} 

fragment_about.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background="#000"> 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="182dp" 
     android:text="ButtonTest" /> 

</RelativeLayout> 

logcat的

對於我個人理解，MainActivity類別設置內容查看到main_activity佈局，那麼，在main_activity。 xml文件，FragmentAbout類被調用來替換片段fragment_about佈局。我對嗎？

請幫幫我！

謝謝！

Answer 1

應該onCreateView()在FragmentAbout

小寫字母 'O' 在未來，嘗試使用了Java註釋@Override避免這種愚蠢的錯誤
