public void addRule (int verb)
Added in API level 1
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 (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.
public void addRule (int verb, int anchor)
Added in API level 1
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 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.
例子
layoutParams.addRule(RIGHT_OF, items[i - 1].getId());
上面的函數設置當前控件在 items[i-1].getId()這個Id對應控件的右側
