Android实现加载广告图片和倒计时的开屏布局

概述这是一个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。

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：

package cn.waps.extend;import androID.app.Activity;import androID.content.Context;import androID.content.res.Configuration;import androID.graphics.color;import androID.graphics.drawable.ShapeDrawable;import androID.graphics.drawable.shapes.RoundRectShape;import androID.os.AsyncTask;import androID.os.Handler;import androID.os.Looper;import androID.vIEw.Gravity;import androID.vIEw.VIEw;import androID.vIEw.VIEwGroup.LayoutParams;import androID.Widget.linearLayout;import androID.Widget.relativeLayout;import androID.Widget.TextVIEw;import com.qcn.wzlz.AppConnect;import com.qcn.wzlz.SDKUtils;public class LoadingPopAd { private final static Handler mHandler = new Handler(); private static LoadingPopAd loadingAppPopAd; public static LoadingPopAd getInstance(){ if(loadingAppPopAd == null){  loadingAppPopAd = new LoadingPopAd(); } if (Looper.myLooper() == null) {  Looper.prepare(); } return loadingAppPopAd; } /** * 获取开屏布局 * @param context * @param time * @return */ public VIEw getContentVIEw(Context context,int time){ return getLoadingLayout(context,time); } private linearLayout getLoadingLayout(final Context context,final int time){ // 整体布局 linearLayout layout = new linearLayout(context);

} // 加载广告图片和倒计时的布局,用与 linearLayout l_layout = new linearLayout(context); l_layout.setGravity(Gravity.CENTER); // 设置LayoutParams,划分额外空间比例为6分之5(具体权重比例可根据自己需求自定义) l_layout.setLayoutParams(new linearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT,1f));
