黑屏之前的Android启动画面

Question

我想在onCreate（）方法中进行所有初始化时显示启动屏幕，但是我需要在屏幕上绘制内容的组件也在初始化，因此，当我启动应用程序时以及onCreate（）之后，出现黑屏方法已完成，则仅绘制了第一个屏幕。与其使用黑屏，不如使用闪屏。

这是我在onCreate方法中的代码：

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

        // Acquire a wakeLock to prevent the phone from sleeping
        PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
        wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "GLGame");

        // Setup all the Game Engine components 
        gameEngineLog = new WSLog("WSGameEngine");
        gameEngineLog.setLogType(this.gameEngineLogType);
        gameLog = new WSLog(this.gameLogTAG);
        gameLog.setLogType(this.gameLogType);
        io = new FileIO(this, getAssets());
        audio = new Audio(this);
        wsScreen = new WSScreen(this, this.screenResizeType, this.customTopYGap, this.customLeftXGap, this.gameScreenWidth, this.gameScreenHeight);
        graphics = new Graphics(this, wsScreen.getGameScreen(), wsScreen.getGameScreenextended());
        renderView = new RenderView(this, wsScreen.getGameScreen(), wsScreen.getGameScreenextended(), FPS, maxFrameskippes);
        input = new Input(this, renderView, logGameEngineInputLog);
        setContentView(renderView);

        if(useOfAnalytics == true) {
            getGameEngineLog().w(classTAG, "Analytics has been enabled");
            analytics = new Analytics(this);
        }

        // Check that the developer has initialized the assets
        if(this.assets == null) {
            this.gameEngineLog.w(classTAG, "The assets for the game haven't been defined!");
        }

    }

我应该如何实现启动屏幕，以避免一开始出现黑屏？

Answer 1

为该初始屏幕创建XML布局，并将其设置为在super.onCreate（）之后的内容视图：

super.onCreate(savedInstanceState);
setContentView (R.layout.splash_screen);

那应该足够了。它将显示此初始屏幕，直到调用setContentView（renderView）为止。
