        height="wrap_content"
        text="ok"
              />

    <LinearLayout

           width="wrap_content"
           height="wrap_content"
           text="ok"
             />

        <Button
            id="del_but"
            width="wrap_content"
            height="wrap_content"
            text="ok"
           />
