Question

这是日食在其布局编辑器中显示的提示：在Eclipse中显示时，在自定义视图中使用View.isInEditMode（）来跳过代码

这是什么意思？这是更详细的错误 java.lang.NoClassDefFoundError：无法初始化类android.os.Environment 在com.amazon.device.ads.DebugProperties.readDebugProperties（DebugProperties.java:78）在com.amazon.device.ads.InternalAdRegistration。（InternalAdRegistration.java:58）在com.amazon.device.ads.InternalAdRegistration。（InternalAdRegistration.java:54）在com.amazon.device.ads.AdLayout.initialize（AdLayout.java:203）在com.amazon.device.ads.AdLayout.initialize（AdLayout.java:183）在com.amazon.device.ads.AdLayout。（AdLayout.java:127） at sun.reflect.NativeConstructorAccessorImpl.newInstance0（at sun.reflect.NativeConstructorAccessorImpl.newInstance（at sun.reflect.DelegatingConstructorAccessorImpl.newInstance）at at java.lang.reflect.Constructor.newInstance（at com.android.ide.eclipse.adt.internal） .editors.layout.ProjectCallback.instantiateClass（ProjectCallback.java:422）在com.android.ide.eclipse.adt.internal.editors.layout.ProjectCallback.loadView（ProjectCallback.java:179）在android.view.BridgeInflater.loadCustomView（BridgeInflater.java:207）在android.view.BridgeInflater.createViewFromTag（BridgeInflater.java:135）在android.view.LayoutInflater.rInflate_Original（LayoutInflater.java:755）在android.view.LayoutInflater_Delegate.rInflate（LayoutInflater_Delegate.java:64）在android.view.LayoutInflater.rInflate（LayoutInflater.java:727）在android.view.LayoutInflater.inflate（LayoutInflater.java:492）在android.view.LayoutInflater.inflate（LayoutInflater.java:373）

我尝试使用代码和xml集成广告，但没有任何作用？这是我的xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:Amazon="http://schemas.android.com/apk/lib/com.amazon.device.ads"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="top|center_horizontal" >

<com.amazon.device.ads.AdLayout  
android:id="@+id/myAdView" 
android:layout_width="match_parent"
android:layout_height="wrap_content" />

我正在使用他们的sdk中的amazon-ads-5.1.153.jar。这是我的main.java

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    preferences = PreferenceManager.getDefaultSharedPreferences(this);
    int defaultValue = R.drawable.blue;
    int themedefault = ThemeChanger.THEME_BLUE;
    appliedtheme = preferences.getInt("mytheme", themedefault);
    AdLayout adView;
    ThemeChanger.onActivityCreateSetTheme(this, appliedtheme);
    setContentView(R.layout.main);

    AdRegistration.setAppKey("AppKey");
    adView = new AdLayout(this);
    adView.loadAd(new AdTargetingOptions());

    AdRegistration.enableTesting(true);
    AdRegistration.enableLogging(true);

    AdTargetingOptions adOptions = new AdTargetingOptions();    
    adView.loadAd(adOptions);

有没有人遇到过这个问题。任何帮助将不胜感激。

您可以在java代码中将广告视为

private static final String APP_KEY =“your app key”; private static final String LOG_TAG =“adsample”;

AdLayout ad;
ViewGroup adcon;

this.adcon =（FrameLayout）findViewById（R.id.root_layout）;

     AdRegistration.enableLogging(true);
        // For debugging purposes flag all ad requests as tests, but set to false for production builds.
        AdRegistration.enableTesting(true);

        try {
            AdRegistration.setAppKey(APP_KEY);
        } catch (final IllegalArgumentException e) {
            Log.e(LOG_TAG, "IllegalArgumentException thrown: " + e.toString());
            return;
        }

        ad = new AdLayout(this,AdSize.SIZE_300x250);
        LayoutParams layoutParams = new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);

        ad.setLayoutParams(layoutParams);
        ad.loadAd();
        adcon.addView(ad);

这确实有效

无法实例化以下类： - com.amazon.device.ads.AdLayout
