Robolectric InflateException bei Verwendung von benutzerdefinierten Aktionsleiste Layout

Question

Ich habe nur Robolectric testen durch diese setup und es gibt mir einen Fehler, wenn ich meine App testen.

Ich habe das Problem auf die ProgressSpinner eingegrenzt, die in meiner benutzerdefinierten ActionBar layout ist. Wenn ich die benutzerdefinierte ActionBar deaktiviere, wird der Test ordnungsgemäß ausgeführt. Ich verwende die normale Aktionsleiste, nicht ActionBarSherlock.

Gibt es einen Workaround?

Testcode

@RunWith(RobolectricTestRunner.class) 
public class MainActivityTest { 

MainActivity activity; 

@Before 
public void setup() 
{ 
    this.activity = Robolectric.buildActivity(MainActivity.class).create().get(); 
} 

@Test 
public void shouldHaveHappySmiles() throws Exception 
{ 
    String hello = this.activity.getString(R.string.app_name); 
    assertThat(hello, equalTo("LFDate")); 
} 

}

Answer 1

erstellen oder project.properties Datei auf Ihrer App-Verzeichnis (nicht testen Verzeichnis hinzufügen, wenn es verschiedene Module)

fügen Sie diese beiden Zeilen neu erstellte Datei

android.library.reference.1=../../build/intermediates/exploded-aar/com.android.support/appcompat-v7/21.0.3 
android.library.reference.2=../../build/intermediates/exploded-aar/com.android.support/support-v4/21.0.3 

Pfade Diese Referenzen zeigen an sollten Manifest-Dateien
