我只想了解 Xamarin.Forms 支持的横幅广告,没有任何补丁或漏洞。是否有任何广告提供商提供带有 Xamarin.Forms 的 SDK?
提前致谢。
最佳答案
Google AdMob 有 SDK 和分步示例适用于 Xamarin.Android。您将需要 Xamarin.GooglePlaySerives.Ads金块。
我用它在我在 Google Play 上发布的 Xamarin.Forms 应用程序中显示广告。
以下是应用程序 android 部分的示例代码:
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Support.V7.App;
using Android.Gms.Ads;
using Android;
namespace AdMobExample
{
[Activity (Label = "@string/app_name", MainLauncher = true)]
public class MainActivity : AppCompatActivity
{
protected AdView mAdView;
protected InterstitialAd mInterstitialAd;
protected Button mLoadInterstitialButton;
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
SetContentView (Resource.Layout.activity_main);
mAdView = FindViewById<AdView> (Resource.Id.adView);
var adRequest = new AdRequest.Builder ().Build ();
mAdView.LoadAd (adRequest);
mInterstitialAd = new InterstitialAd (this);
mInterstitialAd.AdUnitId = GetString (Resource.String.test_interstitial_ad_unit_id);
mInterstitialAd.AdListener = new AdListener (this);
mLoadInterstitialButton = FindViewById<Button> (Resource.Id.load_interstitial_button);
mLoadInterstitialButton.SetOnClickListener (new OnClickListener (this));
}
protected void RequestNewInterstitial ()
{
var adRequest = new AdRequest.Builder ().Build ();
mInterstitialAd.LoadAd (adRequest);
}
protected void BeginSecondActivity ()
{
var intent = new Intent (this, typeof(SecondActivity));
StartActivity (intent);
}
protected override void OnPause ()
{
if (mAdView != null) {
mAdView.Pause ();
}
base.OnPause ();
}
protected override void OnResume ()
{
base.OnResume ();
if (mAdView != null) {
mAdView.Resume ();
}
if (!mInterstitialAd.IsLoaded) {
RequestNewInterstitial ();
}
}
protected override void OnDestroy ()
{
if (mAdView != null) {
mAdView.Destroy ();
}
base.OnDestroy ();
}
class AdListener : Android.Gms.Ads.AdListener
{
MainActivity that;
public AdListener (MainActivity t)
{
that = t;
}
public override void OnAdClosed ()
{
that.RequestNewInterstitial ();
that.BeginSecondActivity ();
}
}
class OnClickListener : Java.Lang.Object, View.IOnClickListener
{
MainActivity that;
public OnClickListener (MainActivity t)
{
that = t;
}
public void OnClick (View v)
{
if (that.mInterstitialAd.IsLoaded) {
that.mInterstitialAd.Show ();
} else {
that.BeginSecondActivity ();
}
}
}
}
}
还有一个 AdMob 广告的分步指南 Xamarin.iOS :
using Google.MobileAds;
...
const string intersitialId = "<Get your ID at google.com/ads/admob>";
Interstitial adInterstitial;
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
CreateAndRequestInterstitial ();
}
public void AfterSomeTime ()
{
if (adInterstitial.IsReady)
adInterstitial.PresentFromRootViewController (navController);
}
void CreateAndRequestInterstitial ()
{
adInterstitial = new Interstitial (intersitialId);
adInterstitial.ScreenDismissed += (sender, e) => {
// Interstitial is a one time use object. That means once an interstitial is shown, HasBeenUsed
// returns true and the interstitial can't be used to load another ad.
// To request another interstitial, you'll need to create a new Interstitial object.
adInterstitial.Dispose ();
adInterstitial = null;
CreateAndRequestInterstitial ();
};
var request = Request.GetDefaultRequest ();
// Requests test ads on devices you specify. Your test device ID is printed to the console when
// an ad request is made. GADBannerView automatically returns test ads when running on a
// simulator. After you get your device ID, add it here
request.TestDevices = new [] { Request.SimulatorId.ToString () };
adInterstitial.LoadRequest (request);
}
