WebView图片下载完成弹窗点击OK后展示Interstitial Ad需求实现

Great question! To make this happen, you’ll need to add a click listener to your dialog’s "OK" button that triggers the interstitial ad when tapped. Here’s a step-by-step solution tailored to your code:

Step 1: Initialize the Interstitial Ad #

First, set up the interstitial ad in your Activity/Fragment (we’ll cover both legacy and latest SDK approaches since Google updated their ad APIs):

Option A: Legacy InterstitialAd (Pre SDK 19.0.0) #

private InterstitialAd interstitialAd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity_layout);

    // Initialize ad with your unique ad unit ID
    interstitialAd = new InterstitialAd(this);
    interstitialAd.setAdUnitId("YOUR_AD_UNIT_ID"); // Replace with your actual ID

    // Load the initial ad
    AdRequest adRequest = new AdRequest.Builder().build();
    interstitialAd.loadAd(adRequest);

    // Register your download complete receiver
    registerReceiver(downloadListener, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}

Option B: Latest InterstitialAd (SDK 19.0.0+) #

Google deprecated the old InterstitialAd class, so use this updated approach:

private InterstitialAd interstitialAd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity_layout);

    // Load ad using the new callback method
    loadInterstitialAd();

    // Register download receiver
    registerReceiver(downloadListener, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}

// Helper method to reload ads after they're shown
private void loadInterstitialAd() {
    AdRequest adRequest = new AdRequest.Builder().build();
    InterstitialAd.load(this, "YOUR_AD_UNIT_ID", adRequest,
        new InterstitialAdLoadCallback() {
            @Override
            public void onAdLoaded(@NonNull InterstitialAd ad) {
                interstitialAd = ad;
                // Set callback to reload ad after it's closed
                ad.setFullScreenContentCallback(new FullScreenContentCallback() {
                    @Override
                    public void onAdDismissedFullScreenContent() {
                        loadInterstitialAd();
                    }

                    @Override
                    public void onAdFailedToShowFullScreenContent(@NonNull AdError adError) {
                        interstitialAd = null;
                        loadInterstitialAd();
                    }
                });
            }

            @Override
            public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
                interstitialAd = null;
                // Handle load failure if needed
            }
        });
}

Step 2: Modify the Dialog to Trigger Ad on OK Click #

Update your BroadcastReceiver to add a click listener to the positive button:

BroadcastReceiver downloadListener = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        new MaterialDialog.Builder(context)
                .title("Download Completed")
                .content("Download Successfully Completed")
                .positiveText("OK")
                .onPositive((dialog, which) -> {
                    // Show ad when OK is clicked
                    if (interstitialAd != null) {
                        // For legacy SDK: Check if ad is loaded first
                        if (interstitialAd.isLoaded()) {
                            interstitialAd.show();
                            // Reload ad for next use
                            interstitialAd.loadAd(new AdRequest.Builder().build());
                        } else {
                            Toast.makeText(context, "Ad not ready yet", Toast.LENGTH_SHORT).show();
                            interstitialAd.loadAd(new AdRequest.Builder().build());
                        }
                        
                        // For latest SDK: Just call show() (it checks load status internally)
                        // interstitialAd.show(YourActivityName.this);
                    } else {
                        Toast.makeText(context, "Ad not ready yet", Toast.LENGTH_SHORT).show();
                        loadInterstitialAd();
                    }
                })
                .show();
    }
};

Step 3: Clean Up Resources #

Avoid memory leaks by unregistering the receiver when your activity is destroyed:

@Override
protected void onDestroy() {
    super.onDestroy();
    if (downloadListener != null) {
        unregisterReceiver(downloadListener);
    }
}

Key Notes #

• Test First: Use Google’s test ad units (e.g., ca-app-pub-3940256099942544/1033173712 for interstitial ads) to avoid policy violations.
• Update Dependencies: Ensure you have the latest SDK in your build.gradle:

  implementation 'com.google.android.gms:play-services-ads:22.4.0' // Check for the latest version
  

• Handle Failures: Add logic to gracefully handle ad load failures so users get clear feedback.
