android – 第二次如何调用interstitial

我想在不止一次的同一活动中显示插页式广告.我正在使用以下方法进行插页式广告,但它只显示插页式广告一次并且从不重新加载.

  int[] images = { R.drawable.r1, R.drawable.r2, R.drawable.r3, R.drawable.r4, R.drawable.r5, R.drawable.r6, R.drawable.r7, R.drawable.r8, R.drawable.r9, R.drawable.r10 /// so on};
     public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState); 
       setContentView(R.layout.main);
    // for interstitial
     interstitial = new InterstitialAd ( this ); 
     interstitial.setAdUnitId (my ad id);
    AdRequest.Builder adRequestBuilder=new AdRequest.Builder ();

    interstitial.setAdListener ( new AdListener (){
    }
    });
   interstitial.loadAd ( adRequestBuilder.Build ());

        hImageViewPic = (ImageView)findViewById(R.id.idImageViewPic);
         iButton = (Button) findViewById(R.id.bNext); 
         gButton = (Button) findViewById(R.id.bPrev); 
       //Just set one Click listener for the image 
        iButton.setonClickListener(iButtonChangeImageListener); 
         gButton.setonClickListener(gButtonChangeImageListener); 
        }
         View.OnClickListener iButtonChangeImageListener = new OnClickListener() { 
         public void onClick(View v) {
        //Increase Counter to move to next Image 
          currentimage++;
         currentimage = currentimage % images.length; 
       hImageViewPic.setimageResource(images[currentimage]); 

         / / here to show interstitial
          if (interstitial. isLoaded ()){
              interstitial.show ();
           }
         } }; 
        View.OnClickListener gButtonChangeImageListener = new OnClickListener() { 
         public void onClick(View v) { 
         //Increase Counter to move to next Image 
           currentimage--; 
            currentimage = (currentimage + images.length) % images.length; 
           hImageViewPic.setimageResource(images[currentimage]);
           } 
           };

当我按下按钮然后插页式显示.我希望将间隙显示为一些图像.例如,在10日和20日之后或之后或之后5分钟等.请帮助我如何回忆间隙并在一些图像之后显示它.请帮我编写代码或编辑我的代码.我完全不知道如何才能完成这项任务.我会非常感激的.

解决方法:

将您的adlistener代码修改为

interstitial.setAdListener(new AdListener() {


 @Override
      public void onAdLoaded() {

      }

      @Override
      public void onAdFailedToLoad(int errorCode) {
            long timestamp = System.currentTimeMillis();
            if(timestamp > lastTimeAdFail + 120*1000)
            {
              AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();

                // Load the interstitial ad again
            interstitial.loadAd(adRequest);
            }

      }

      @Override
      public void onAdClosed () 
      {
          AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();

            // Load the interstitial ad again
          interstitial.loadAd(adRequest);
      }
    });

同时修改你的onclick监听器

View.OnClickListener iButtonChangeImageListener = new OnClickListener() { 
         public void onClick(View v) {
        //Increase Counter to move to next Image 
          currentimage++;
         currentimage = currentimage % images.length; 
       hImageViewPic.setimageResource(images[currentimage]); 
 if (interstitial.isLoaded()) {
                            long timestamp = System.currentTimeMillis();

                                if(timestamp > lastTimeAdShown + 300*1000)
                                {
                                    interstitial.show();

                                    lastTimeAdShown = timestamp;
                                }

                            }
                            else 
                            {
                                long timestamp = System.currentTimeMillis();
                                if(timestamp > lastTimeAdFail + 120*1000)
                                {
                                    AdRequest adRequest = new AdRequest.Builder()
                                    .addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();

                                    // Load the interstitial ad.
                                    interstitial.loadAd(adRequest);

                                    lastTimeAdFail = timestamp;
                                }
                            }

         } }; 

编辑：将两个类变量定义为

private long lastTimeAdShown=System.currentTimeMillis();

private long lastTimeAdFail=System.currentTimeMillis();
