java - 将 "Native Advanced Ads"放入弹出窗口关闭

Question

我尝试在您关闭应用程序时将高级广告放入对话框中，但是当您打开对话框时，第一次不会加载广告。 ...我担心我会在应用程序中加载广告 没有出现并在关闭时我把它放在对话框中，因为担心代理认为下载广告不出现是谷歌违规行为

            .build();

    NativeAdOptions adOptions = new NativeAdOptions.Builder()
            .setVideoOptions(videoOptions)
            .build();
    builder.withNativeAdOptions(adOptions);

        @Override

        }
    }).build();
    adLoader.loadAd(new AdRequest.Builder().build());
    videoStatus.setText("");

现在我试图将代码刷新方法放在对话框中而不是刷新方法

public void showdilog(){
                builder = new AdLoader.Builder(this, ADMOB_AD_UNIT_ID);
    builder.forUnifiedNativeAd(new UnifiedNativeAd.OnUnifiedNativeAdLoadedListener() {

        @Override
        public void onUnifiedNativeAdLoaded(UnifiedNativeAd unifiedNativeAd) {
            // You must call destroy on old ads when you are done with them,
            // otherwise you will have a memory leak.
            if (nativeAd != null) {
                nativeAd.destroy();
            }
            nativeAd = unifiedNativeAd;
            FrameLayout frameLayout =
                    findViewById(R.id.fl_adplaceholder);
             adView = (UnifiedNativeAdView) getLayoutInflater()
                    .inflate(R.layout.ad_unified, null);
            populateUnifiedNativeAdView(unifiedNativeAd, adView);
            frameLayout.removeAllViews();
            frameLayout.addView(adView);
        }

    });
    VideoOptions videoOptions = new VideoOptions.Builder()
            .setStartMuted(startVideoAdsMuted.isChecked())
            .build();

    NativeAdOptions adOptions = new NativeAdOptions.Builder()
            .setVideoOptions(videoOptions)
            .build();
    builder.withNativeAdOptions(adOptions);

    AdLoader adLoader = builder.withAdListener(new AdListener() {
        @Override
        public void onAdFailedToLoad(int errorCode) {
            refresh.setEnabled(true);
            Toast.makeText(MainActivity.this, "Failed to load native ad: "
                    + errorCode, Toast.LENGTH_SHORT).show();
        }
    }).build();
    adLoader.loadAd(new AdRequest.Builder().build());
              AlertDialog.Builder builder = new AlertDialog.Builder(this);
                 bulider.setView(adView);
        builder.setMessage(R.string.onfirm_exit)
                .setCancelable(false)
                .setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        finish();
                    }
                })
                .setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                });
        AlertDialog alert = builder.create();
        alert.show();

     }

Answer 1

您正在做的是同时构建和显示对话框。因此，在您显示对话框时，您也在加载原生广告。您应该提前构建对话框，并且不要在构建函数中调用 alert.show()。

因此，请提前在 MainActivity 中调用您的 buildDialog()。

在您的 onBackPressed 函数中调用 alert.show()。

希望对您有所帮助。
