android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="startPhotoLibAction"
android:src="@drawable/library_blau_2" />

You have to use style="?android:attr/borderlessButtonStyle":
<ImageButton
android:id="@+id/btn_photo_lib"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="startPhotoLibAction"
android:src="@drawable/library_blau_2"
style="?android:attr/borderlessButtonStyle"/>

I found this works just fine:
android:background=”@null”
Answer：
Just change the background of your imageview to transparent as below:
<ImageButton
android:id="@+id/btn_photo_lib"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/transparent" <----- Set background.
android:onClick="startPhotoLibAction"
android:src="@drawable/library_blau_2" />
OR You can only set the background then you don’t need to apply the transparent color.
<ImageButton
android:id="@+id/btn_photo_lib"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/download" <--- set only the background
android:onClick="startPhotoLibAction"
/>
