java - Admob 6.4.1 - 膨胀类 com.google.ads.AdView 时出错

Question

将 admob 添加到我的 xml 时，会导致 fatal error ，从而导致应用程序崩溃。

我在/libs 中正确添加了 admob jar 并构建路径。

xml 看起来像这样

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="right" >

    <com.google.ads.AdView 
                        xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
                         android:id="@+id/adView"
                         android:layout_width="wrap_content"
                         android:layout_height="wrap_content"
                         ads:adUnitId="#######"
                         ads:adSize="BANNER"
                         ads:testDevices="######"
                         ads:loadAdOnCreate="true"/> </RelativeLayout>

这里是logcat

Answer 1

好的，根据您的评论，我将发布之前的建议作为带有一些示例代码的答案，因为正如您所指出的，您对 Android 还很陌生。

您当前的代码:

public class WebViewActivity extends DroidGap {
    public static String LOG_TAG = "name";
    private Dialog mLoadingDialog;

    @Override public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getActionBar().setCustomView(R.layout.ab); // <-- !!
        getActionBar().setDisplayShowCustomEnabled(true);
        getActionBar().setDisplayShowHomeEnabled(false);
    }
}

基本上，您应该尝试重写上面指出的行。不要将自定义 View 膨胀委托(delegate)给 ActionBar，而是自行膨胀以确保使用 Activity 上下文。就像这样:

public class WebViewActivity extends DroidGap {
    public static String LOG_TAG = "name";
    private Dialog mLoadingDialog;

    @Override public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View customActionBarView = getLayoutInflater().inflate(R.layout.ab, null, false);
        getActionBar().setCustomView(customActionBarView);
        getActionBar().setDisplayShowCustomEnabled(true);
        getActionBar().setDisplayShowHomeEnabled(false);
    }
}

这应该(可能)消除您当前看到的异常。我没有验证或尝试运行上面的代码 fragment ，因此请注意任何拼写错误。如果您在此之后仍然遇到同样的问题，请轻推我，我会仔细看看。
