Question

我正在尝试在我的应用上测试adMob。我按照https://developers.google.com/mobile-ads-sdk/docs/admob/android/quick-start中的步骤进行操作，除了这部分外，一切看起来都很好：

它在网站上说：“在RelativeLayout中添加PlaceHolder片段，并在PlaceHolder片段下面包含AdFragment：”

<fragment   android:name="com.google.android.gms.example.bannerexample.MyActivity$PlaceholderFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@+id/adFragment" />

<fragment
            android:id="@+id/adFragment"
            android:name="com.google.android.gms.example.bannerexample.MyActivity$AdFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true" />

当我将这个部分添加到我的xml时，下面的这部分有一个红色，它说“无法解析符号”

.example.bannerexample.MyActivity$PlaceholderFragment

没有解释，我想我必须根据我的应用程序改变这一行的某些部分，但哪一部分？

还是我遗漏的其他东西？

更新：

logcat说：

Caused by: android.app.Fragment$InstantiationException: Unable to instantiate fragment com.google.android.gms.example.bannerexample.MyActivity$PlaceholderFragment: make sure class name exists, is public, and has an empty constructor that is public

更新2：

我通过使用“com.myc.myapp.myactivity $ PlaceholderFragment”更改整行解决了这个问题

广告布局上没有任何内容，只是空白。

更新3：

我添加了一个adListener，我从onAdLoaded函数中获取了toast。但除了我的其他布局外，屏幕上没有任何内容。我用于广告的布局是空的。

mAdView.setAdListener(new AdListener() {
                @Override
                public void onAdOpened() {
                    // Save app state before going to the ad overlay.
                }

                @Override
                public void onAdFailedToLoad(int errorCode) {
                    super.onAdFailedToLoad(errorCode);
                    msg = errorCode +"";
                    Toast.makeText(c, msg, Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onAdLoaded() {
                    super.onAdLoaded();
                    msg = "done";
                    Toast.makeText(c, msg, Toast.LENGTH_SHORT).show();
                }
            });

我的课程，我想要显示添加：

                // Create an ad request. Check logcat output for the hashed device ID to
                // get test ads on a physical device. e.g.
                // "Use AdRequest.Builder.addTestDevice("ABCDEF012345") to get test ads on this device."
                AdRequest adRequest = new AdRequest.Builder()

                mAdView.loadAd(adRequest);

如果您想要测试广告，请参阅： https://developers.google.com/mobile-ads-sdk/docs/admob/android/banner#test_ads

否则，请查看您的日志，以确保正在发送广告请求以及响应是什么。
