这是我启用 Robolectric 的 JUnit 测试类的一个片段：

@Before
    public void setUp() throws Exception
    {
        mActivity = new LanguageSelection();
        mActivity.onCreate(null);

        speakEnglishButton = (Button) mActivity.findViewById(com.jameselsey.apps.androidsam.R.id.speakEnglishButton);
        speakSpanishButton = (Button) mActivity.findViewById(com.jameselsey.apps.androidsam.R.id.speakSpanishButton);
        speakFrenchButton = (Button) mActivity.findViewById(com.jameselsey.apps.androidsam.R.id.speakFrenchButton);
        speakGermanButton = (Button) mActivity.findViewById(com.jameselsey.apps.androidsam.R.id.speakGermanButton);
        speakItalianButton = (Button) mActivity.findViewById(com.jameselsey.apps.androidsam.R.id.speakItalianButton);
    }

    @Test
    public void testButtonsVisible()
    {
        assertThat(speakEnglishButton.getVisibility(), equalTo(View.VISIBLE));
        assertThat(speakSpanishButton.getVisibility(), equalTo(View.VISIBLE));
        assertThat(speakFrenchButton.getVisibility(), equalTo(View.VISIBLE));
        assertThat(speakGermanButton.getVisibility(), equalTo(View.VISIBLE));
        assertThat(speakItalianButton.getVisibility(), equalTo(View.VISIBLE));
    }

运行我的测试时，该行mActivity.onCreate(null)会引发以下异常：

languageselection.xml如果我从我的布局文件中注释掉以下视图，它工作得非常好：

<com.admob.android.ads.AdView
                android:id="@+id/ad"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:gravity="bottom"
                androidsam:backgroundColor="#000000"
                androidsam:primaryTextColor="#FFFFFF"
                androidsam:secondaryTextColor="#CCCCCC"/>

问题：对此有什么好的解决方法？我不想仅仅出于测试目的而禁用/启用广告。我不是在测试广告，但我不想为了测试其他元素（例如按钮）而删除它们。

谢谢

我建议将代码片段移到您从方法中查找 admob 广告的onCreate位置，然后将它们放入onResume直接调用的方法中onCreate。

// Look up the AdView as a resource and load a request.
AdView adView = (AdView) this.findViewById(R.id.adView);

// Request an advertisement
AdRequest request = new AdRequest();
request.setTesting(true); //This is used for testing on emulator. Does not affect production
adView.loadAd(request);

我不确定它为什么会爆炸，但它对我有用。
