将解析信息添加到Robolectric包管理器中

Question

这个问题与我想做的非常相似：How can I shadow the PackageManager with Robolectric

但是，所有答案都依赖于ShadowApplication.setPackageManager()。在2.2中，这种方法似乎不再存在：http://robolectric.org/javadoc/org/robolectric/shadows/ShadowApplication.html

我试图抓取包管理器并添加一个解决方案信息：

    RobolectricPackageManager packageManager = (RobolectricPackageManager) Robolectric.application.getPackageManager();
    Intent intent = new Intent(Intent.ACTION_MAIN,null);
    intent.addCategory(Intent.CATEGORY_HOME);
    ResolveInfo ri = new ResolveInfo();
    ActivityInfo ai = new ActivityInfo();
    ai.packageName = "com.fun.test";
    ri.activityInfo = ai;
    ri.isDefault = true;
    packageManager.addResolveInfoForIntent(intent, ri);

但没有结果。有人知道怎么做吗？

Answer 1

Intent.resolveActivity期望ResolveInfo具有以下内容：

if (info != null) {
    return new ComponentName(
            info.activityInfo.applicationInfo.packageName,
            info.activityInfo.name);
}

在此基础上，我在Robolectro2.3中做了以下工作：

RobolectricPackageManager packageManager = (RobolectricPackageManager) shadowOf(Robolectric.application).getPackageManager();
Intent intent = ... //create an Intent like the one you want to resolve

ResolveInfo info = new ResolveInfo();
info.isDefault = true;

ApplicationInfo applicationInfo = new ApplicationInfo();
applicationInfo.packageName = "com.example";
info.activityInfo = new ActivityInfo();
info.activityInfo.applicationInfo = applicationInfo;
info.activityInfo.name = "Example";

packageManager.addResolveInfoForIntent(intent, info);

Answer 2

您应该将解析信息添加为列表：

packageManager.addResolveInfoForIntent(intent, Collections.singletonsList(ri));
