Android ui Test mit Espresso kann nicht verwendet werden Fresko SimpleDreweeView

Question

Jetzt möchte ich Espresso verwenden, um meine app ui zu testen, aber wenn ich Fresko-Bibliothek verwenden, wie ein SimpleDreweeView in xml, wird der Espresso mit Fehlern nicht bestanden:

android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class com.facebook.drawee.view.SimpleDraweeView 
at android.view.LayoutInflater.inflate(LayoutInflater.java:551) 
at android.view.LayoutInflater.inflate(LayoutInflater.java:429) 
at android.view.LayoutInflater.inflate(LayoutInflater.java:380) 
at com.android.internal.policy.PhoneWindow.setContentView(PhoneWindow.java:474) 
at android.app.Activity.setContentView(Activity.java:2388) 
at com.example.android.testing.espresso.intents.AdvancedSample.ImageViewerActivity.onCreate(ImageViewerActivity.java:45) 

So kann mir jeder helfen, das Problem zu lösen ?? Danke vielmals!!

Meine XML-Datei:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       xmlns:tools="http://schemas.android.com/tools" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:orientation="vertical" 
       android:padding="@dimen/activity_horizontal_margin" 
       tools:context=".ImageViewerActivity"> 

    <Button android:id="@+id/button_take_photo" 
      style="?android:attr/buttonStyleSmall" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="@string/button_open_camera" 
      android:layout_gravity="center_horizontal" 
      android:onClick="onOpenCamera" 
      android:layout_marginTop="32dp"/> 

    <com.facebook.drawee.view.SimpleDraweeView 
     android:layout_width="128dp" 
     android:layout_height="128dp" 
     android:id="@+id/imageView" 
     android:layout_gravity="center_horizontal" 
     android:layout_marginTop="32dp" 
     android:background="#ffdbdbdb"/> 

</LinearLayout> 

ImageViewActivity:

public class ImageViewerActivity extends Activity { 

    @VisibleForTesting 
    protected static final String KEY_IMAGE_DATA = "data"; 

    private static final int REQUEST_IMAGE_CAPTURE = 1; 

    private SimpleDraweeView mImageView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_image_viewer); 
     mImageView = (SimpleDraweeView) findViewById(R.id.imageView); 
    } 

    private void dispatchTakePictureIntent() { 
     // Open the camera to take a photo. 
     Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
      startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); 
     } 
    } 

    public void onOpenCamera(View view) { 
     dispatchTakePictureIntent(); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // If an image is received, display it on the ImageView. 
     if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
      Bundle extras = data.getExtras(); 
      if (extras == null || !extras.containsKey(KEY_IMAGE_DATA)) { 
       return; 
      } 
      Bitmap imageBitmap = (Bitmap) extras.get(KEY_IMAGE_DATA); 
      mImageView.setImageBitmap(imageBitmap); 
     } 
    } 
} 

ich die Google offizielle Demo nur ändern, ersetzen Sie die Bildansicht simpledraweeview und fehleranfällig ....

In Ihr Fall Schreiben

@Override 
public void onCreate() { 
    super.onCreate(); 
    Fresco.initialize(this); 
    setContentView(R.layout.activity_image_viewer); 
}
