java - requestFeature() before adding content error when trying to make AndEngine work with Google Play Game Service

Question

我正在开发一款使用 AndEngine 的游戏。

AndEngine 有一个“BaseGameActivity”，Google Play 游戏服务也有。我不得不将 BaseGameActivity 从 AndEngine 重命名为 AEBaseGameActivity，并将其作为父类 BaseGameActivity 而不是 Activity。

但它给我这个错误:

Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content
        at com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:226)
        at org.andengine.util.ActivityUtils.requestFullscreen(ActivityUtils.java:56)
        at org.andengine.ui.activity.AEBaseGameActivity.applyEngineOptions(AEBaseGameActivity.java:427)
        at org.andengine.ui.activity.AEBaseGameActivity.onCreate(AEBaseGameActivity.java:83)

现在AndEngine有这段代码:

public static void requestFullscreen(final Activity pActivity) {
        final Window window = pActivity.getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        window.requestFeature(Window.FEATURE_NO_TITLE);
    }

如果我评论 requestFeature 行，我的项目就会运行!但是它有一个难看的标题栏。

请问有人知道解决这个问题的方法吗？

编辑，这里是一些更多的代码:

PS: AEBaseGameActivity.php 扩展了 BaseActivity，它扩展了 BaseGameActivity(以前只是 Activity )

AEBaseGameActivity.php

public abstract class AEBaseGameActivity extends BaseActivity implements IGameInterface, IRendererListener {
    @Override
    protected void onCreate(final Bundle pSavedInstanceState) {
        if(BuildConfig.DEBUG) {
            Debug.d(this.getClass().getSimpleName() + ".onCreate" + " @(Thread: '" + Thread.currentThread().getName() + "')");
        }

        super.onCreate(pSavedInstanceState);

        this.mGamePaused = true;

        this.mEngine = this.onCreateEngine(this.onCreateEngineOptions());
        this.mEngine.startUpdateThread();

        this.applyEngineOptions(); //REQUEST FULLSCREEN

        this.onSetContentView(); //SET CONTENT VIEW
    }

    ...

    private void applyEngineOptions() {
        final EngineOptions engineOptions = this.mEngine.getEngineOptions();

        if(engineOptions.isFullscreen()) {
            ActivityUtils.requestFullscreen(this); //ACTIVITY UTIL SHOWN LATER
        }

        ...
    }

    ...

    protected void onSetContentView() {
        this.mRenderSurfaceView = new RenderSurfaceView(this);
        this.mRenderSurfaceView.setRenderer(this.mEngine, this);

        this.setContentView(this.mRenderSurfaceView, AEBaseGameActivity.createSurfaceViewLayoutParams());
    }
}

ActivityUtils.java

public class ActivityUtils {

    public static void requestFullscreen(final Activity pActivity) {
        final Window window = pActivity.getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        window.clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        window.requestFeature(Window.FEATURE_NO_TITLE); //IF COMMENTING THIS, THE GAME IS RUNNING
    }

    ...

}

编辑2:

代码基本只有AndEngine，这里是原代码:

https://github.com/nicolasgramlich/AndEngine/tree/GLES2/src/org/andengine/ui/activity

我的改变:

• 将 BaseGameActivity 重命名为 AEBaseGameActivity
• BaseActivity 扩展了 BaseGameActivity(取自 Google Play 游戏服务)而不是 Activity
• 从 Google Play 游戏服务的 BaseGameUtils 获取的 BaseGameActivity 和 GameHelper.java。

Answer 1

好的，这就是我所做的:

• 我注释掉了导致问题的行(AndEngine 的 ActivityUtils.java 第 56 行)

• 我在 Android Manifest 的 Activity 中添加了这个:

  android:theme="@android:style/Theme.NoTitleBar"

它最终看起来像这样:

<activity
                android:name=".GameActivity"
                android:theme="@android:style/Theme.NoTitleBar"
                android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
