How to remove an empty field at the top of PhotoView?

Upload a picture to the PhotoView component. Obtained empty fields above and below the picture.

How to remove them? I do this:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ll_scr1" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <com.github.chrisbanes.photoview.PhotoView android:id="@+id/ivScr1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" /> <WebView android:id="@+id/wv_scr1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" /> </LinearLayout>
