Robolectric包管理器不會爲getNameForUid返回正確的值嗎？

Question

即使添加了包，我仍然收到空。我查看了源代碼，結果發現StubPackageManager總是返回null，並且沒有辦法覆蓋整個PackageManager類。

Answer 1

在設置：

MockPackageManager mockPackageManager = new MockPackageManager(
    Robolectric.getShadowsAdapter()); 
RuntimeEnvironment.setRobolectricPackageManager(mockPackageManager); 

子類：

class MockPackageManager extends DefaultPackageManager { 

    public MockPackageManager(ShadowsAdapter shadowsAdapter) { 
    super(shadowsAdapter); 
    } 

    @Override 
    public String getNameForUid(int uid) { 
    switch (uid) { 
     case UID_A: 
     return NAME_A; 
     case UID_B: 
     return NAME_B; 
     default: 
     return null; 
    } 
    } 

    @Override 
    public boolean isPermissionRevokedByPolicy(String s, String s1) { 
    return false; 
    } 
}
