XML attributes
android:layout_margin
Specifies extra space on the left, top, right and bottom sides of this view. If both layout_margin and any of layout_marginLeft, layout_marginRight, layout_marginStart, layout_marginEnd, layout_marginTop, and layout_marginBottom are also specified, the layout_margin value will take precedence over the edge-specific values. This space is outside this view's bounds. Margin values should be positive.
May be a dimension value, which is a floating point number appended with a
unit such as "14.5sp
".
Available units are: px (pixels), dp (density-independent pixels),
sp (scaled pixels based on preferred font size), in (inches), and
mm (millimeters).
android:layout_marginBottom
Specifies extra space on the bottom side of this view. This space is outside this view's bounds. Margin values should be positive.
May be a dimension value, which is a floating point number appended with a
unit such as "14.5sp
".
Available units are: px (pixels), dp (density-independent pixels),
sp (scaled pixels based on preferred font size), in (inches), and
mm (millimeters).

android:layout_marginEnd
Specifies extra space on the end side of this view. This space is outside this view's bounds. Margin values should be positive.
May be a dimension value, which is a floating point number appended with a
unit such as "14.5sp
".
Available units are: px (pixels), dp (density-independent pixels),
sp (scaled pixels based on preferred font size), in (inches), and
mm (millimeters).
Related methods:
android:layout_marginHorizontal
Specifies extra space on the left and right sides of this view. Specifying layout_marginHorizontal is equivalent to specifying layout_marginLeft and layout_marginRight. If both layout_marginHorizontal and either/both of layout_marginLeft and layout_marginRight are also specified, the layout_marginHorizontal value will take precedence over the edge-specific values. Also, layout_margin will always take precedence over any of these values, including layout_marginHorizontal. This space is outside this view's bounds. Margin values should be positive.

android:layout_marginLeft
Specifies extra space on the left side of this view. This space is outside this view's bounds. Margin values should be positive.

android:layout_marginStart
Specifies extra space on the start side of this view. This space is outside this view's bounds. Margin values should be positive.
May be a dimension value, which is a floating point number appended with a
unit such as "14.5sp
".
Available units are: px (pixels), dp (density-independent pixels),

Related methods:
android:layout_marginTop
Specifies extra space on the top side of this view. This space is outside this view's bounds. Margin values should be positive.
May be a dimension value, which is a floating point number appended with a
unit such as "14.5sp
".
Available units are: px (pixels), dp (density-independent pixels),

mm (millimeters).
Related methods:
android:layout_marginVertical
Specifies extra space on the top and bottom sides of this view. Specifying layout_marginVertical is equivalent to specifying layout_marginTop and layout_marginBottom with that same value. If both layout_marginVertical and either/both of layout_marginTop and layout_marginBottom are also specified, the layout_marginVertical value will take precedence over the edge-specific values. Also, layout_margin will always take precedence over any of these values, including layout_marginVertical. This space is outside this view's bounds. Margin values should be positive.
