我有一个ImageButton设计不完全可见的自定义,因此当我执行单击操作时,我收到此错误:
android.support.test.espresso.PerformException: Error performing 'single click' on view 'with id: test.com.myproject.app:id/navigationButtonProfile'.
Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints:
at least 90 percent of the view's area is displayed to the user.

按钮的一小部分位于屏幕之外(即,它在顶部被裁剪),可能按钮的12%在屏幕外.这是设计使然,无法滚动或执行任何视图操作以使其可见.任何人都知道如何超越这个90%的约束？
解决方案: 我按照建议创建了自己的点击操作,并且完美运行.我从Google Espresso中复制了该类,并在此方法中将其从90更改为75: …
是否可以使用浓缩咖啡检查背景颜色是否与给定颜色匹配？
我制作了一个自定义匹配器,类似于@Irfan建议的,谢谢!
public static Matcher<Object> backgroundShouldHaveColor(int expectedColor) {
return buttondShouldHaveBackgroundColor(equalTo(expectedColor));
}
private static Matcher<Object> buttonShouldHaveBackgroundColor(final Matcher<Integer> expectedObject) {
final int[] color = new int[1];
return new BoundedMatcher<Object, Button>( Button.class) {
@Override
public boolean matchesSafely(final Button actualObject) {
color[0] =((ColorDrawable) actualObject.getBackground()).getColor();
if( expectedObject.matches(color[0])) {
return true;
} else {
return false;
}
}
@Override
public void describeTo(final Description description) {
// Should be improved!
description.appendText("Color did not match "+color[0]);
}
};
}
我将 compose 添加到现有项目中。我用compose重写了一个fragment ui，当我启动该fragment时，需要很长时间才能启动。
从另一个片段添加一个片段：
val fragment = FragmentWithComposeUi()
requireActivity().addFragment(fragment, R.id.fragment_container, "FragmentWithComposeUi")
addFragment()添加片段的功能。
fun FragmentActivity.addFragment(fragment: Fragment, container: Int, tag:String) {
val currentFragment = supportFragmentManager.findFragmentByTag(tag)
if (currentFragment == null) {
supportFragmentManager.beginTransaction()
.setReorderingAllowed(true)
.add(container, fragment, tag)
.addToBackStack(tag)
.commit()
}
}
FragmentWithComposeUi 类：
class FragmentWithComposeUi: Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
return ComposeView(requireContext()).apply{
setContent {
//some ui
}
}
}
构建.gradle
我也尝试使用新的 compose 版本 1.3.0-alpha01，但没有帮助。
buildscript {
ext {
compose_version = '1.1.1'
compose_compiler_version = …在我的应用程序中,当用户单击"注册"按钮时,将启动RegisterActivity.一旦用户填写表单,详细信息将发布到Web服务,如果注册成功,则RegisterActivity会使用RESULT_OK.这在以下代码示例中进行了总结:
public void submitRegistration() {
showProgressDialog(R.string.registration, R.string.please_wait);
getWebApi().register(buildRegistrationFromUI(), new Callback<ApiResponse>() {
@Override
public void success(ApiResponse apiResponse, Response response) {
hideProgressDialog();
setResult(RESULT_OK);
finish();
}
@Override
public void failure(RetrofitError error) {
hideProgressDialog();
showErrorDialog(ApiError.parse(error));
}
});
}
使用Espresso,如何检查活动是否已完成setResult(RESULT_OK).
请注意:我不希望创建一个模拟的意图,我想查的意图结果状态.
我尝试用浓咖啡点击全屏视图,如下所示:
onView(withId(R.id.id)).perform(click());
但得到这个错误:
Error performing 'Send down montion event' on view 'unknown'
...

当我在其他设备(如Nexus 6和S4)上运行测试时,测试运行正常,但在三星Galaxy S3上它会抛出此异常.
