得到结束后活动结果（）;在Android单元测试 [英] Get result from an activity after finish(); in an Android unit test

问题描述

我目前正在写一些Android的单元测试，虽然我已经得到了大多数事情的工作就是我想要的，有一件事已经离开那种我难住了。

I'm currently writing some Android unit tests, and while I've gotten most things to work the way I want, one thing has left me kind of stumped.

我有以下的code在我的活动测试：

I have the following code in my activity under test:

Intent result = new Intent();
result.putExtra("test", testinput.getText().toString());
setResult(Activity.RESULT_OK, result);
finish();

我试图找出如何使用规范（或其他），能够读取活动的结果，或者得到的意图的活动结束后。 任何人都可以帮忙吗？

I'm trying to figure out how to use Instrumentation (or whatever) to be able to read the result of the activity, or get at the intent after the activity is finished. Can anyone help?

推荐答案

您可以使用反射，并直接从活动抢值。

You can use reflection and grab the values directly from the Activity.

protected Intent assertFinishCalledWithResult(int resultCode) {
  assertThat(isFinishCalled(), is(true));
  try {
    Field f = Activity.class.getDeclaredField("mResultCode");
    f.setAccessible(true);
    int actualResultCode = (Integer)f.get(getActivity());
    assertThat(actualResultCode, is(resultCode));
    f = Activity.class.getDeclaredField("mResultData");
    f.setAccessible(true);
    return (Intent)f.get(getActivity());
  } catch (NoSuchFieldException e) {
    throw new RuntimeException("Looks like the Android Activity class has changed it's   private fields for mResultCode or mResultData.  Time to update the reflection code.", e);
  } catch (Exception e) {
    throw new RuntimeException(e);
  }
}
