Android 11（SDK 版本 30）的自适应横幅 - Kotlin - 已弃用

Question

下午好。这是我在社区的第一次咨询。我正在尝试使用官方文档实现自适应横幅，但该示例包含已弃用的术语，而且 Android Studio 提供的帮助让我感到困惑。我在论坛上找了几个小时，但没有找到可以帮助我的答案。如果您能帮助我使用 Kotiln 为 SDK 30 实现自适应横幅，我将不胜感激。

private lateinit var adView: AdView

private val adSize: AdSize
    get() {
        val display = windowManager.defaultDisplay
        val outMetrics = DisplayMetrics()
        display.getMetrics(outMetrics)

        val density = outMetrics.density

        var adWidthPixels = frameAnuncio.width.toFloat()
        if (adWidthPixels == 0f) {
            adWidthPixels = outMetrics.widthPixels.toFloat()
        }

        val adWidth = (adWidthPixels / density).toInt()
        return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth)
    }

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_receta)
    val toolbar: Toolbar = findViewById(R.id.toolbar)
    setSupportActionBar(toolbar)
    supportActionBar?.setDisplayHomeAsUpEnabled(true)

    MobileAds.initialize(this) { }

    adView = AdView(this)
    frameAnuncio.addView(adView)
    loadBanner()

}

private fun loadBanner() {
    adView.adUnitId = AD_UNIT_ID

    adView.adSize = adSize

    val adRequest = AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build()

    adView.loadAd(adRequest)
}

companion object {
    private val AD_UNIT_ID = "ca-app-pub-3940256099942544~3347511713"
}

Admob 依赖项是：实施 'com.google.android.gms: play-services-ads: 19.6.0'

谢谢

Answer 1

对于第一部分，您可以使用 windowManager.currentDisplayMetrics 访问 window 边界。和resources.displayMetrics获取密度。

private val adSize: AdSize
    get() {
        val metrics = windowManager.currentWindowMetrics

        val density = resources.displayMetrics.density

        var adWidthPixels = frameAnuncio.width.toFloat()
        if (adWidthPixels == 0f) {
            adWidthPixels = metrics.bounds.width().toFloat()
        }

        val adWidth = (adWidthPixels / density).toInt()
        return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth)
    }

添加测试设备的新方法在documentation here中有说明。

尝试使用它为文档中的原始代码片段提供相同的值

private AdSize getAdSize() {

    DisplayMetrics outMetrics = getResources().getDisplayMetrics();

    float widthPixels = getScreenWidth();
    float density = outMetrics.density;

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

    return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth);

}

public int getScreenWidth() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        WindowMetrics windowMetrics = getWindowManager().getCurrentWindowMetrics();
        Insets insets = windowMetrics.getWindowInsets()
                .getInsetsIgnoringVisibility(WindowInsets.Type.systemBars());
        return windowMetrics.getBounds().width() - insets.left - insets.right;
    } else {
        DisplayMetrics outMetrics = getResources().getDisplayMetrics();
        return outMetrics.widthPixels;
    }
}
