android - Strange Black Background after setMeasuredDimension in Custom ImageView -

i have library allows circularimageview have problem can't fix.

i add in layout way:

<linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:gravity="center"     android:orientation="vertical">      <linearlayout         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="1"         android:gravity="center"         android:orientation="vertical">      <com.mikhaellopez.circularimageview.circularimageview         android:id="@+id/circularimageview"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:src="@drawable/test"         app:civ_border="true"         app:civ_border_color="#3f51b5"         app:civ_border_width="8dp"         app:civ_shadow="true"         app:civ_shadow_color="#3f51b5"         app:civ_shadow_radius="10" />  </linearlayout>  <linearlayout     android:layout_width="240dp"     android:layout_height="wrap_content"     android:gravity="center"     android:orientation="vertical">      <seekbar-         android:layout_width="match_parent"         android:layout_height="wrap_content" />      <!-- ... -->  </linearlayout> 

on picture have black background appears in view (on png images ic_launcherfor example works well):

i can fix problem when change onmesure method.

before:

@override protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {     int width = measurewidth(widthmeasurespec);     int height = measureheight(heightmeasurespec);     int imagesize = (width < height) ? width : height;     setmeasureddimension(imagesize, imagesize); } 

after:

@override protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {     int width = measurewidth(widthmeasurespec);     int height = measureheight(heightmeasurespec);     /*int imagesize = (width < height) ? width : height;     setmeasureddimension(imagesize, imagesize);*/     setmeasureddimension(width, height); } 

but modification view isn't centered:

could me fix black background or find new way center view?
