活動與景觀

我試圖建立一個設置活動我的Android應用程序設置碎片的碰撞，它適用於人像，但是當我打開風景模式崩潰活動與景觀

這裏是我的代碼

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_height="wrap_content" 
    android:layout_width="wrap_content"> 

<fragment  android:name="project.android.udacity.com.popularmovies.app.SettingsFragment" 
    android:id="@+id/settings_content" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

</fragment> 
</LinearLayout> 


public class SettingsFragment extends PreferenceFragment { 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    addPreferencesFromResource(R.xml.pref_general); 
} } 

public class SettingsActivity extends AppCompatActivity { 

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

    getFragmentManager().beginTransaction() 
      .replace(R.id.settings_content, new SettingsFragment()) 
      .commit(); 
} }

和錯誤日誌

我不知道如何解決它，爲什麼肖像作品？

您是否在縱向和橫向模式下使用不同的佈局？ –

沒有我使用了橫向和縱向 –

相同的佈局嘗試在你的清單像... '<活動安卓補充一點：configChanges =「方向|屏幕布置|鍵盤| keyboardHidden |屏幕尺寸」' –

因爲你的片段在XML已經定義你不需要下面的一段代碼

getFragmentManager().beginTransaction() 
     .replace(R.id.settings_content, new SettingsFragment()) 
     .commit();

。

啊啊，謝謝，多虧了一個小菜... –

覆蓋onCreateView，而不是SettingsFragment類中的onCreate方法。

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View fragmentView = inflater.inflate(R.layout.your_fragment_layout, container, true); 

    return fragmentView; 
}

他settings fragment是一個'PreferenceFragment'，你不會覆蓋'onCreateView'。 – Jin
