Android FrameLayout 내의 ChildView들의 위치제어하기

방법 1. Gravity 사용하기

아주 직관적인 flag를 사용하여 사용이 간편하고 쉽습니다.

Gravity flag 확인하기   Constants
int	AXIS_CLIP	Raw bit controlling whether the right/bottom edge is clipped to its container, based on the gravity direction being applied.
int	AXIS_PULL_AFTER	Raw bit controlling how the right/bottom edge is placed.
int	AXIS_PULL_BEFORE	Raw bit controlling how the left/top edge is placed.
int	AXIS_SPECIFIED	Raw bit indicating the gravity for an axis has been specified.
int	AXIS_X_SHIFT	Bits defining the horizontal axis.
int	AXIS_Y_SHIFT	Bits defining the vertical axis.
int	BOTTOM	Push object to the bottom of its container, not changing its size.
int	CENTER	Place the object in the center of its container in both the vertical and horizontal axis, not changing its size.
int	CENTER_HORIZONTAL	Place object in the horizontal center of its container, not changing its size.
int	CENTER_VERTICAL	Place object in the vertical center of its container, not changing its size.
int	CLIP_HORIZONTAL	Flag to clip the edges of the object to its container along the horizontal axis.
int	CLIP_VERTICAL	Flag to clip the edges of the object to its container along the vertical axis.
int	DISPLAY_CLIP_HORIZONTAL	Special constant to enable clipping to an overall display along the horizontal dimension.
int	DISPLAY_CLIP_VERTICAL	Special constant to enable clipping to an overall display along the vertical dimension.
int	FILL	Grow the horizontal and vertical size of the object if needed so it completely fills its container.
int	FILL_HORIZONTAL	Grow the horizontal size of the object if needed so it completely fills its container.
int	FILL_VERTICAL	Grow the vertical size of the object if needed so it completely fills its container.
int	HORIZONTAL_GRAVITY_MASK	Binary mask to get the horizontal gravity of a gravity.
int	LEFT	Push object to the left of its container, not changing its size.
int	NO_GRAVITY	Constant indicating that no gravity has been set
int	RIGHT	Push object to the right of its container, not changing its size.
int	TOP	Push object to the top of its container, not changing its size.
int	VERTICAL_GRAVITY_MASK	Binary mask to get the vertical gravity of a gravity.

방법 2. margin 사용하기

자식뷰들에게 margin을 적용하기 위해서는 일단 부모뷰FramLayout의 top이나 bottom에 붙여야적용이 됩니다.

 

<!-- .xml 리소스 파일의 속성으로 사용하기 -->

<FrameLayout ... >

    <TextView ... android:layout_gravity="top" android:layout_marginLeft="44dp" />

</FrameLayout>

 

// .java 소스 파일의 메쏘드로 사용하기

Button btn = new Button(this);
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CO

        NTENT, LayoutParams.WRAP_CONTENT);

params.gravity = Gravity.TOP;
params.setMargins (int left, int top, int right, int bottom);
btn.setLayoutParams(params);
