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).

• setMargins(int,int,int,int)

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:

• setMarginEnd(int)

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.

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_marginTop

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

Related methods:

• setMargins(int,int,int,int)

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.
