问题 - 仅在一项活动中展示的横幅广告

如何解决问题 - 仅在一项活动中展示的横幅广告

我使用了两个活动，每个活动上都有一个横幅

我的问题是，在我的 MainActivity 上它工作正常，但是一旦我的第二个活动启动，我就没有显示任何内容，但我只进行了复制和粘贴（通过修改 setContentView 等元素...）

我正在与您分享我的代码，希望能得到一些帮助！

public class PlayActivity extends Activity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_play);
    
        ironsource.init(this,"YOUR_APP_KEY",ironsource.AD_UNIT.BANNER);

        final FrameLayout bannerContainer = findViewById(R.id.bannerContainer);
        final ironsourceBannerLayout banner = ironsource.createBanner(this,ISBannerSize.BANNER);
        FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.WRAP_CONTENT);
        bannerContainer.addView(banner,layoutParams);

        banner.setBannerListener(new BannerListener() {
                @Override
                public void onBannerAdLoaded() {
                    banner.setVisibility(View.VISIBLE);
                }

                @Override
                public void onBannerAdLoadFailed(ironsourceError error) {
                    // Called after a banner has attempted to load an ad but Failed.
                    runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                bannerContainer.removeAllViews();
                            }
                        });
                }

                @Override
                public void onBannerAdClicked() {
                    // Called after a banner has been clicked.
                }

                @Override
                public void onBannerAdScreenPresented() {
                    // Called when a banner is about to present a full screen content.
                }

                @Override
                public void onBannerAdScreendismissed() {
                    // Called after a full screen content has been dismissed
                }

                @Override
                public void onBannerAdLeftApplication() {
                    // Called when a user would be taken out of the application context.
                }
            });

        ironsource.loadBanner(banner);
        // YOUR OTHER CODE //
        // YOUR OTHER CODE //
        // YOUR OTHER CODE //
    }
    
    protected void onResume() {
        super.onResume();
        ironsource.onResume(this);
    }
    protected void onPause() {
        super.onPause();
        ironsource.onPause(this);
    }
}

我看不出哪里有问题，为了显示我使用的第二个活动：

startActivity(new Intent(MainActivity.this,PlayActivity.class));

我真的希望有人有解决方案

解决方法

PlayActivity.java 代码示例显示您使用 createBanner() 方法从头开始创建横幅视图。

基于 IronSource 文档： https://developers.ironsrc.com/ironsource-mobile/android/banner-integration-android/#step-4

试着打电话

IronSource.destroyBanner(banner);

之前

startActivity(new Intent(MainActivity.this,PlayActivity.class));
