我使用两个活动，每个活动都有一个横幅

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，我什么都没有显示，但我只做了一个复制和粘贴（通过修改 setContentView 等元素......）

我正在与您分享我的代码，希望能找到一些帮助！

AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.fujiiyo.ufotraveler">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:networkSecurityConfig="@xml/network_security_config"
        android:usesCleartextTraffic="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".SplashScreenActivity"
            android:configChanges="orientation|screenSize"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".MainActivity">
        </activity>
        <activity
            android:name=".PlayActivity">
        </activity>
    </application>
</manifest>

活动播放.xml：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".PlayActivity">

    <FrameLayout
        android:id="@+id/bannerContainer"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_gravity="bottom"
        android:visibility="visible"
        android:background="#FF000000"/>

</FrameLayout>

PlayActivity.java：

package com.fujiiyo.ufotraveler;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.FrameLayout;
import com.ironsource.mediationsdk.ISBannerSize;
import com.ironsource.mediationsdk.IronSource;
import com.ironsource.mediationsdk.IronSourceBannerLayout;
import com.ironsource.mediationsdk.logger.IronSourceError;
import com.ironsource.mediationsdk.sdk.BannerListener;

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, 0, 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，要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

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);

前

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