本文是爱站技术频道小编介绍的实现加载广告和倒计时的开屏,其实Android可以用来加载广告图片和倒计时布局,程序中设置了布局参数,下面就跟着爱站技术频道小编来了解吧。

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);
 layout.setOrientation(LinearLayout.VERTICAL);
 layout.setGravity(Gravity.CENTER);
 int bg_id = context.getResources().getIdentifier("loading_bg", "drawable", context.getPackageName());
 if(bg_id != 0){
  layout.setBackgroundResource(bg_id);
 }
 // 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));
 // 加载图片的布局
 RelativeLayout pop_layout = new RelativeLayout(context);
 TextView timeView = new TextView(context);
 timeView.setText("剩余" + time + "秒");
 timeView.setTextSize(10);
 timeView.setTextColor(Color.BLACK);
 timeView.setPadding(8, 3, 6, 2);
 int num = 12;
 // 对手机进行屏幕判断
 int displaySize = SDKUtils.getDisplaySize(context);
 if(displaySize == 320){
  num = 8;
 }else if(displaySize == 240){
  num = 6;
 }else if(displaySize == 720){
  num = 16;
 }else if(displaySize == 1080){
  num = 20;
 }
 float[] outerRadii = new float[] { 0, 0, num, num, 0, 0, num, num};
 ShapeDrawable timeView_shapeDrawable = new ShapeDrawable();
 timeView_shapeDrawable.setShape(new RoundRectShape(outerRadii, null, null));
 timeView_shapeDrawable.getPaint().setColor(Color.argb(255, 255, 255, 255));
 timeView.setBackgroundDrawable(timeView_shapeDrawable);
 //异步执行倒计时
 //异步加载广告图片
 new ShowPopAdTask(context, pop_layout, timeView).execute();
 new TimeCountDownTask(timeView, time).execute();
 TextView textView = new TextView(context);
 textView.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 5f));
 textView.setText("正在启动,请稍后...");
 textView.setGravity(Gravity.CENTER);
 textView.setTextColor(Color.WHITE);
 l_layout.addView(pop_layout);
 layout.addView(l_layout);
 layout.addView(textView);
 return layout;
 }
 private class TimeCountDownTask extends AsyncTask<Void, Void, Boolean>{

 @Override

  try {
  height_full = ((Activity)context).getWindowManager().getDefaultDisplay().getHeight();
  int height_tmp = height_full - 75;//75为设备状态栏加标题栏的高度
  height = height_tmp * 5/6;
  while(true){
   if(((Activity)context).getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE
   && height_full <= 480){

    }
    pop_layout.addView(timeView, params);
    }
   });
   break;
   }
   try {
   Thread.sleep(500);
   } catch (InterruptedException e) {
   e.printStackTrace();
   }
  }
  } catch (Exception e) {
  e.printStackTrace();
  }
  return null;
 }
 }
}
