java - 在OnCreateView中显示Admob插页式广告时，无法加载Android fragment 布局

使用AdMob在我的应用中展示广告时遇到了一些问题。该问题如主题中所述。

这是我的入门 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>

这是我的应用程序中的2个片段:

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R.id.fragment_container设置为MenuFragment。在MenuFragment中，我有启动NextFragment的按钮(用此片段替换R.id.fragment_container)。问题出在OnCreateView的NextFragment类中...

我已经花了很多时间尝试解决问题，但现在我如此绝望，我什至准备了一个显示该问题的样本小型Eclipse项目:
https://drive.google.com/file/d/0ByRNGNhz-adOQ091OU15c3ZUckE/view?usp=sharing

您必须在strings.xml中更改广告单元ID，并在requestNewInterstitial方法中的MainActivity.java中设置测试设备的ID以显示广告...(并且可能会修复一些链接错误？-不知道Google Play服务是否会为你们正确链接)

我将悬赏给那些解决问题的人...

更新1:在我的其中一台设备上-三星galaxy s4 mini-无论使用测试广告还是真实广告，都会出现此问题。但是，似乎在我的另一台设备LG-D320n上，似乎仅在使用测试广告时才出现此问题...我现在完全感到困惑了...

更新2:添加应用程序的完整logcat(应用程序中没有任何崩溃，但是抛出了很多消息。关闭广告后，仅没有视图，我使用“后退按钮”手动退出了应用程序)

最佳答案

尝试将您的广告展示代码包装成这样的片段:

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

间隙广告有可能以某种方式损害您片段的生命周期。

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