Android Junit 测试失败，出现 "Only the original thread that created a view hierarchy can touch its views."

Question

我对 Android 非常陌生，正在使用 Robotium 编写一些基本的 Android 测试，但失败并出现异常

"android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views."

下面是基本的测试用例描述:-

测试用例:-

public void testSearch() {
                        Activity a = getActivity();
            SearchItemActivity search = new SearchItemActivity(solo);
            search.searchText("ipod", a);   

    }

 SearchItemActivity.searchText(String) is defined as

    public void searchText(final String search, Activity act) {
                Button v = (Button) act
                .findViewById(com.test.mobile.R.id.text_search_field);
                ((Button) v).setText("");
                ((Button) v).setText(search);
                solo.sendKey(Solo.ENTER);
                solo.waitForActivity("FoundItemdDetailActivity");
                solo.assertCurrentActivity("Expected FoundItemDetail activity","FoundItemdDetailActivity");
    }

任何关于如何修改我的代码的建议都将不胜感激

Answer 1

@UiThreadTest
public void yourMethod() {

@UiThreadTest 注释告诉 Android 构建此方法，以便它在 UI 线程上运行。这允许该方法在被测应用程序中更改微调器小部件的状态。 @UiThreadTest 的这种使用表明，如有必要，您可以在 UI 线程上运行整个方法。
