java - 在 OnCreateView 中显示 Admob 插页式广告时未加载 Android fragment 布局

Question

我在使用 AdMob 的应用程序中展示广告时遇到了一些问题。问题如题中所述。

这是我的开始 Activity 课:

package com.example.admobinterstitial;

import android.os.Bundle;

import com.google.android.gms.ads.AdListener;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.InterstitialAd;

import android.support.v4.app.FragmentActivity;
import android.view.Window;
import android.view.WindowManager;

public class MainActivity extends FragmentActivity
{
    public static InterstitialAd mInterstitialAd;

    @Override
    protected void onCreate(Bundle savedInstanceState) { 
        // Super
        super.onCreate(savedInstanceState);
         // Turn off the window's title bar
        requestWindowFeature(Window.FEATURE_NO_TITLE);
         // Fullscreen mode
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_main);

        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd.setAdUnitId(getResources().getString(R.string.loading_add_id));

        mInterstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                requestNewInterstitial();
            }
        });
        requestNewInterstitial();

        if (findViewById(R.id.fragment_container) != null) 
        {
            if (savedInstanceState != null) {
                return;
            }
            // Create a new Fragment to be placed in the activity layout
            Fragments.MenuFragment firstFragment = new Fragments.MenuFragment();

            // In case this activity was started with special instructions from an
            // Intent, pass the Intent's extras to the fragment as arguments
            firstFragment.setArguments(getIntent().getExtras());

            // Add the fragment to the 'fragment_container' FrameLayout
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.fragment_container, firstFragment, firstFragment.getClass().toString()).commit();
        }  
    }

    private void requestNewInterstitial() {
        AdRequest adRequest = new AdRequest.Builder()
                  .addTestDevice("my test device ID blabla")
                  .build();

        mInterstitialAd.loadAd(adRequest);
    }


}

主要 Activity 布局:

RelativeLayout 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="${relativePackage}.${activityClass}" >

    <FrameLayout
        android:id="@+id/fragment_container"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/bg_color" >
    </FrameLayout>

</RelativeLayout>

这是我的应用中的 2 个 fragment :

package com.example.admobinterstitial;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

public class Fragments
{
    public static class MenuFragment extends Fragment 
    {
        Context mContext;

        @Override
        public void onAttach(Activity activity) {
            super.onAttach(activity);
            mContext = activity;
        }


        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            final View rootView = inflater.inflate(R.layout.menu_fragment, container, false);

            Button myButton = (Button) rootView.findViewById(R.id.myButton);
            myButton.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {

                    NextFragment newFragment = new NextFragment();
                    FragmentManager man = ((FragmentActivity)mContext).getSupportFragmentManager();

                    android.support.v4.app.FragmentTransaction transaction = man.beginTransaction();
                    transaction.replace(R.id.fragment_container, newFragment, newFragment.getClass().toString());
                    transaction.addToBackStack(null);
                    transaction.commit();
                }
            });

            return rootView;
        }
    };

    public static class NextFragment extends Fragment 
    {       
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            final View rootView = inflater.inflate(R.layout.next_fragment, container, false);

            //TODO After showing the ad here, views in my R.layout.next_fragment won't show up after closing the ad.
            //With those 2 lines commented, the views show up correctly...
            if (MainActivity.mInterstitialAd.isLoaded()) 
                MainActivity.mInterstitialAd.show();

            return rootView;
        }
    };
}

在 MainActivity 中，我只是将我的 R.id.fragment_container 设置为我的 MenuFragment。在 MenuFragment 中，我有启动 NextFragment 的按钮(用此 fragment 替换 R.id.fragment_container)。问题出在 OnCreateView 的 NextFragment 类中...

我已经花了很多时间试图解决这个问题，现在我非常绝望，我什至准备了一个示例小型 eclipse 项目来展示这个问题: https://drive.google.com/file/d/0ByRNGNhz-adOQ091OU15c3ZUckE/view?usp=sharing

您必须在 strings.xml 中更改您的广告单元 ID，并在 MainActivity.java 中的 requestNewInterstitial 方法中设置您的测试设备 ID 以显示广告...(并且可能修复一些链接错误？ - 不确定谷歌是否播放服务将为你们正确链接)

我将悬赏给任何解决问题的人......

更新 1:在我的一台设备上 - samsung galaxy s4 mini - 无论我使用测试广告还是真实广告都会出现问题。但似乎在我的另一台设备 LG-D320n 上，问题似乎只在使用测试广告时出现......我现在完全困惑......

更新 2:添加完整的应用程序 logcat(应用程序中没有任何崩溃，但抛出了很多消息。关闭广告后没有 View ，我使用“后退按钮”手动退出应用程序)

Answer 1

尝试将您的广告展示代码包装成这样的 fragment :

rootView.post(
        new Runnable() {
            @Override
            public void run() {
                if (MainActivity.mInterstitialAd.isLoaded()) 
                    MainActivity.mInterstitialAd.show();
            }
        }
);

插页式广告可能会以某种方式损害 fragment 的生命周期。

或者您可以尝试使用 postDelayed(Runnable runnable, long delay); 进行试验，并以适当设置的延迟显示广告。也许这会有所帮助。
