[Solved] I’m making weightSum but it can’t be sorted


add

android:layout_gravity="center_vertical"

to both your ImageView and your Button, that will give you the alignment you depicted in your image.

<LinearLayout
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="horizontal"
              android:weightSum="100" >

      <ImageView
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_gravity="center_vertical"
              android:layout_weight="80"
              android:gravity="right"
              android:src="https://stackoverflow.com/questions/25706451/@drawable/image" />

      <Button
              android:id="@+id/blah"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_gravity="center_vertical"
              android:layout_weight="20"
              android:gravity="left"
              android:text="Blah blah blah blah"
              android:textSize="15sp" />
</LinearLayout>

Also you didn’t set the height for your button.
