ActivityUnitTestCase和startActivity与ActionBarActivity [英] ActivityUnitTestCase and startActivity with ActionBarActivity

问题描述

我尝试测试活动，它使用ActionBarActivity（从appcompat库）。我需要一个自定义的应用程序能够操纵DI系统加载后台服务我的测试服务，而不是。

I try to test a Activity which uses ActionBarActivity (from the appcompat library). I need a custom Application to be able to manipulate the DI system to load my test service instead of the real service.

如果我有我的测试编写，并调用startActivity我收到以下错误：

If I have my test written and call startActivity I get the following error:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

如果我打电话launchActivityWithIntent活动启动时没有任何问题，但它是用嘲笑的应用程序类的我真正应用类代替。任何想法如何，我可以解决这个问题或者我怎么能执行code中的应用程序的onCreate被称为后，但之前的onCreate我的活动获取的所谓的在我的仪器测试？

If I call launchActivityWithIntent the Activity starts without any problems but It is using my Real Application class instead of the Mocked Application class. Any ideas how I can fix that or how I can execute code after onCreate of the application was called but before onCreate of my Activity get's called within my instrument test?

推荐答案

我发现，如果我创建一个自定义MockApplication并添加以下code：

I found out that if I create a custom MockApplication and add the following code:

@Override
public void onCreate() {
    super.onCreate();
    setTheme(R.style.AppTheme);
}

我希望会为其他人正常工作。

I hope that will work for other people as well.
