實現firebase-ui和appcompat引發「requestFeature（）必須在添加內容之前調用」

我有這個實現的問題。不使用火力的UI執行，如可以在代碼1可以看出，運行完美實現firebase-ui和appcompat引發「requestFeature（）必須在添加內容之前調用」

如果啓用火力的UI如圖代碼2，它在執行產生一個錯誤的GetWindow

代碼1：

public class MainActivity extends Activity { 
    //private Firebase mFirebaseRef; 

    private ImageButton buttonMostrar; 
    private ImageButton buttonMostrarJirafa; 
    private ImageButton buttonMostrarPanda; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    //Firebase.setAndroidContext(this); 

    getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS); 

    setContentView(R.layout.activity_main); 
    ...

代碼2

個

public class MainActivity extends FirebaseLoginBaseActivity { 

    private Firebase mFirebaseRef; 

    private ImageButton buttonMostrar; 
    private ImageButton buttonMostrarJirafa; 
    private ImageButton buttonMostrarPanda; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     Firebase.setAndroidContext(this); 

     getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS); 

     setContentView(R.layout.activity_main); 
    ...

依賴關係：

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile 'com.firebase:firebase-client-android:2.3.1' 
    compile 'com.firebaseui:firebase-ui:0.3.1' 
    compile 'com.android.support:cardview-v7:23.1.1' 
}

錯誤：

注：與火力的UI整合獨自完美的作品。

¿想法？

修飾：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    supportRequestWindowFeature(Window.FEATURE_CONTENT_TRANSITIONS); 
    super.onCreate(savedInstanceState); 
    Firebase.setAndroidContext(this); 

    //getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS); 

    setContentView(R.layout.activity_main);

現在誤差超過的setContentView（R.layout.activity_main）;

重建和作品！

按照錯誤消息：

Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content

相反，super.onCreate()調用之前使用supportRequestWindowFeature()：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    supportRequestWindowFeature(Window.FEATURE_CONTENT_TRANSITIONS); 
    super.onCreate(savedInstanceState); 
    Firebase.setAndroidContext(this); 

    setContentView(R.layout.activity_main);

感謝伊恩！ ...我改變了代碼，但現在我有其他錯誤到setContentView（R.layout.activity_main），我將修改和佈局留在主帖子中。 –

您是否嘗試過搜尋新的錯誤訊息？在這一點上，這是一個完全不同的問題（已經解決了很多次）。 – ianhanniballake

是的，但恐怕問題來自「..extends FirebaseLoginBaseActivity」我們可以放棄，對吧？ –
