android - 如何获取自适应横幅 (Admob) API 30 的尺寸

Question

由于 API 30 中已弃用方法 getDefaultDisplay(); 和 getMetrics()，以下代码无法正常工作。

private AdSize getAdSize() {
    Display display = getWindowManager().getDefaultDisplay();//deprecated
    DisplayMetrics outMetrics = new DisplayMetrics();
    display.getMetrics(outMetrics);//deprecated

    float density = outMetrics.density;
    float widthPixels = adContainerView.getWidth();

    if (widthPixels == 0) {
        widthPixels = outMetrics.widthPixels;
    }

    int adWidth = (int) (widthPixels / density);

    return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth);
}

Google 要求使用 WindowMetrics#getBounds() 获取应用程序窗口区域的尺寸，并使用 Configuration#densisDpi 获取当前密度。

我找到了 API 30 的这些方法，但我不知道如何使用它们。

final WindowMetrics metrics = windowManager.getCurrentMetrics();
 // Gets all excluding insets
 final WindowInsets windowInsets = metrics.getWindowInsets();
 Insets insets = windowInsets.getInsets(WindowInsets.Type.navigationBars());
 final DisplayCutout cutout = windowInsets.getCutout();
 if (cutout != null) {
     final Insets cutoutSafeInsets = Insets.of(cutout.getSafeInsetsLeft(), ...);
     insets = insets.max(insets, cutoutSafeInsets);
 }

 int insetsWidth = insets.right + insets.left;
 int insetsHeight = insets.top + insets.bottom;

 // Legacy size that Display#getSize reports
 final Size legacySize = new Size(metrics.getWidth() - insetsWidth,
         metrics.getHeight() - insetsHeight);

有人遇到过这种情况吗？

我使用这个方法:

private AdSize getAdSize() {
    DisplayMetrics outMetrics = getResources().getDisplayMetrics();
    float widthPixels = outMetrics.widthPixels;
    float density = outMetrics.density;
    int adWidth = (int) (widthPixels / density);
    return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(requireContext(), adWidth);
}

对于 LinearLayout，用于查看自适应横幅:

    LinearLayout banner_view = findViewById(R.id.banner_view);
    AdView adView = new AdView(requireActivity().getApplicationContext());
    adView.setAdUnitId(getString(R.string.my_banner_id));
    banner_view.addView(adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    AdSize adSize = getAdSize(); // Code above
    adView.setAdSize(adSize);
    adView.loadAd(adRequest);
