实现firebase-ui和appcompat抛出“在添加内容之前必须调用RequestFeature（）”

Question

  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);
     ...

  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);
    ...

依赖关系：

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'
}

错误：

 注意：仅与firebase-ui的集成就可以完美地工作。

你的想法？

修改：

@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);

重建和工作！

Answer 1

根据错误消息：

由：Android.util.AndroidRuntimeException引起：在添加内容之前必须调用requestFeature（）

相反，在super.oncreate()调用之前使用supportRequestWindowFeature（）：

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

  setContentView(R.layout.activity_main);
