Android实现加载广告图片和倒计时的开屏布局

这是一个android开屏布局的实例，可以用于加载广告图片和倒计时的布局。程序中设置的LayoutParams,划分额外空间比例为6分之5，具体权重比例可根据用户自己需求来自定义，异步加载广告图片，相关的Android代码。

具体实现代码如下：

packagecn.waps.extend;
importandroid.app.Activity;
importandroid.content.Context;
importandroid.content.res.Configuration;
importandroid.graphics.Color;
importandroid.graphics.drawable.ShapeDrawable;
importandroid.graphics.drawable.shapes.RoundRectShape;
importandroid.os.AsyncTask;
importandroid.os.Handler;
importandroid.os.Looper;
importandroid.view.Gravity;
importandroid.view.View;
importandroid.view.ViewGroup.LayoutParams;
importandroid.widget.LinearLayout;
importandroid.widget.RelativeLayout;
importandroid.widget.TextView;
importcom.qcn.wzlz.AppConnect;
importcom.qcn.wzlz.SDKUtils;

privatefinalstaticHandlermHandler=newHandler();
privatestaticLoadingPopAdloadingAppPopAd;
publicstaticLoadingPopAdgetInstance(){
if(loadingAppPopAd==null){
loadingAppPopAd=newLoadingPopAd();
}
if(Looper.myLooper()==null){
Looper.prepare();
}
returnloadingAppPopAd;
}
