Answer 2

<Button android:id="@+id/save"
                android:layout_width="match_parenr"
                android:layout_height="wrap_content"
                android:layout_marginBottom="5.0dip"
                android:text="@string/save"
                android:textAlignment="center"
                android:textAppearance="@style/Base.TextAppearance.AppCompat.Large"
                android:background="@drawable/selector_btn"
                android:drawableLeft="@android:drawable/ic_menu_save"
                 android:layout_marginTop="50dp"
                android:textColor="@color/text_white"/>

You should give height of button to wrap_content
