黑屏之前的Android闪屏 [英] Android Splash Screen before black screen
问题描述
我想显示启动画面,而一切都初始化在OnCreate()方法,但我需要画的东西在屏幕上也初始化组件,因此有一个黑色的屏幕,当我启动应用程序,后的onCreate()方法完成则仅是绘制的第一个屏幕。而不必黑屏,我想一个启动画面。
I would like to display a splash screen while everything is initializing in the onCreate() method, yet components that I need to draw things to the screen are also initializing, therefore there's a black screen when I start the app and after the onCreate() method has completed then only is the first screen drawn. Instead of having the black screen I'd like a splash screen.
下面是我的code。在onCreate方法:
Here's my code in the onCreate method:
@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
如何实现闪屏,避免黑屏的开头?
How should I implement a splash screen, to avoid the black screen at the beginning?
推荐答案
这个闪屏创建一个XML布局和设置您的super.onCreate为内容视图右后():
Create a XML layout for this splash screen and set it as content view right after your super.onCreate():
super.onCreate(savedInstanceState);
setContentView (R.layout.splash_screen);
这应该是足够了。这将显示该开机画面,直到你的setContentView(的RenderView)被调用。
That should be enough. It would display this splash screen until your setContentView(renderView) is called.
