  • addRule

    public void addRule(int verb)

    Adds a layout rule to be interpreted by the RelativeLayout. This method should only be used for constraints that don't refer to another sibling (e.g., CENTER_IN_PARENT) or take a boolean value (RelativeLayout.TRUE for true or 0 for false). To specify a verb that takes a subject, use addRule(int, int) instead.

    Parameters:

    verb - One of the verbs defined by RelativeLayout, such as ALIGN_WITH_PARENT_LEFT.

    See Also:

    addRule(int, int)

  • addRule

    public void addRule(int verb,
               int anchor)

    Adds a layout rule to be interpreted by the RelativeLayout. Use this for verbs that take a target, such as a sibling (ALIGN_RIGHT) or a boolean value (VISIBLE).

    Parameters:

    verb - One of the verbs defined by RelativeLayout, such as ALIGN_WITH_PARENT_LEFT.

    anchor - The id of another view to use as an anchor, or a boolean value(represented as RelativeLayout.TRUE) for true or 0 for false). For verbs that don't refer to another sibling (for example, ALIGN_WITH_PARENT_BOTTOM) just use -1.

    See Also:

    addRule(int)

  • removeRule

    public void removeRule(int verb)

    Removes a layout rule to be interpreted by the RelativeLayout.

    Parameters:

    verb - One of the verbs defined by RelativeLayout, such as ALIGN_WITH_PARENT_LEFT.

    See Also:

    addRule(int), addRule(int, int)

  • getRules

    public int[] getRules(int layoutDirection)

    Retrieves a complete list of all supported rules, where the index is the rule verb, and the element value is the value specified, or "false" if it was never set. If there are relative rules defined (*_START / *_END), they will be resolved depending on the layout direction.

    Parameters:

    layoutDirection - the direction of the layout. Should be either View.LAYOUT_DIRECTION_LTR or View.LAYOUT_DIRECTION_RTL

    Returns:

    the supported rules

    See Also:

    addRule(int, int)

  • getRules

    public int[] getRules()

    Retrieves a complete list of all supported rules, where the index is the rule verb, and the element value is the value specified, or "false" if it was never set. There will be no resolution of relative rules done.

    Returns:

    the supported rules

    See Also:

    addRule(int, int)

  • resolveLayoutDirection

    public void resolveLayoutDirection(int layoutDirection)

    Description copied from class: ViewGroup.MarginLayoutParams
    This will be called by View.requestLayout(). Left and Right margins may be overridden depending on layout direction.

    Overrides:

    resolveLayoutDirection in class ViewGroup.MarginLayoutParams

    Parameters:

    layoutDirection - the direction of the layout View.LAYOUT_DIRECTION_LTR View.LAYOUT_DIRECTION_RTL
