Inherited XML attributes

From class LayoutParams android:layout_height Specifies the basic height of the view. This is a required attribute for any view inside of a containing layout manager. Its value may be a dimension (such as "12dip") for a constant height or one of the special constants. 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). Must be one of the following constant values. Constant Value Description fill_parent ffffffff The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent. match_parent ffffffff The view should be as big as its parent (minus padding). Introduced in API Level 8. wrap_content fffffffe The view should be only big enough to enclose its content (plus padding). android:layout_width Specifies the basic width of the view. This is a required attribute for any view inside of a containing layout manager. Its value may be a dimension (such as "12dip") for a constant width or one of the special constants. 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). Must be one of the following constant values. Constant Value Description fill_parent ffffffff The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent. match_parent ffffffff The view should be as big as its parent (minus padding). Introduced in API Level 8. wrap_content fffffffe The view should be only big enough to enclose its content (plus padding).

Inherited constants

From class LayoutParams Int FILL_PARENT Special value for the height or width requested by a View. FILL_PARENT means that the view wants to be as big as its parent, minus the parent's padding, if any. This value is deprecated starting in API Level 8 and replaced by MATCH_PARENT. Int MATCH_PARENT Special value for the height or width requested by a View. MATCH_PARENT means that the view wants to be as big as its parent, minus the parent's padding, if any. Introduced in API Level 8. Int WRAP_CONTENT Special value for the height or width requested by a View. WRAP_CONTENT means that the view wants to be just large enough to fit its own internal content, taking its own padding into account.

XML attributes

android:layout_margin

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

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

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).

android:layout_marginHorizontal

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_marginLeft

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.

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_marginRight

android:layout_marginRight

Specifies extra space on the right 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_marginStart

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), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

android:layout_marginTop

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), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

android:layout_marginVertical

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.

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).
