AndroidApplication类学习

AndroidApplicationextends Activity implements Application

首先继承了android的Activity，并实现了Application接口

public void initialize (ApplicationListener listener, AndroidApplicationConfiguration config)

{

//创建2D的渲染对象
graphics = new AndroidGraphics(this, config, config.resolutionStrategy == null ? new FillResolutionStrategy(): config.resolutionStrategy);

//创建输入对象
input = new AndroidInput(this, graphics.view, config);

//创建音频对象
audio = new AndroidAudio(this);

//创建文件操作对象
files = new AndroidFiles(this.getAssets());

this.listener = listener;

this.handler = new Handler();

Gdx.app = this;
Gdx.input = this.getInput();
Gdx.audio = this.getAudio();
Gdx.files = this.getFiles();
Gdx.graphics = this.getGraphics();

//设置全屏模式

try

{

//没标题
requestWindowFeature(Window.FEATURE_NO_TITLE);
}

catch (Exception ex)

{
log("AndroidApplication", "Content already displayed, cannot request FEATURE_NO_TITLE", ex);
}

//设置全屏模式
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

//也可以用下面的清除Flag
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

//设置运行的显示View

//DefaultGLSurfaceView
setContentView(graphics.getView(), createLayoutParams());

createWakeLock(config);
