뷰의 패딩과 여백의 차이

뷰의 여백과 패딩의 차이점은 무엇입니까?

---

패딩 의 의미를 기억하는 데 도움이되도록 두꺼운면 패딩 이 많은 큰 코트를 생각 합니다. 나는 코트 안에 있지만 패딩 코트는 나와 함께 있습니다. 우리는 단위입니다.

하지만 여백 을 기억하기 위해 " 이봐, 나에게 약간의 여백을 줘! " 라고 생각한다 . 그것은 나와 너 사이의 빈 공간이다. 내 안전 지대, 내 여유로 오지마.

더 명확하게하기 위해 다음은 패딩과 여백의 그림입니다 TextView.

Padding is the space inside the border, between the border and the actual view's content. Note that padding goes completely around the content: there is padding on the top, bottom, right and left sides (which can be independent).

Margins are the spaces outside the border, between the border and the other elements next to this view. In the image, the margin is the grey area outside the entire object. Note that, like the padding, the margin goes completely around the content: there are margins on the top, bottom, right, and left sides.

An image says more than 1000 words (extracted from Margin Vs Padding - CSS Properties):

---

Padding is inside of a View.

Margin is outside of a View.

This difference may be relevant to background or size properties.

---

Padding is within the view, margin is outside. Padding is available for all views. Depending on the view, there may or may not be a visual difference between padding and margin.

For buttons, for example, the characteristic button background image includes the padding, but not the margin. In other words, adding more padding makes the button look visually bigger, while adding more margin just makes the gap between the button and the next control wider.

For TextViews, on the other hand, the visual effect of padding and margin is identical.

Whether or not margin is available is determined by the container of the view, not by the view itself. In LinearLayout margin is supported, in AbsoluteLayout (considered obsolete now) - no.

Below image will let you understand the padding and margin-

---

Padding means space between widget and widget original frame. But the margin is space between widget's original frame to boundaries other widget's frame..

---

Padding is the space inside the border between the border and the actual image or cell contents. Margins are the spaces outside the border, between the border and the other elements next to this object.

---

Sometimes you can achieve the same result by playing only with padding OR margin. Example :

Say View X contains view Y (aka : View Y is inside View X).

-View Y with Margin=30 OR View X with Padding=30 will achieve the same result: View Y will have an offset of 30.

Padding
Padding is inside of a View.For example if you give android:paddingLeft=20dp, then the items inside the view will arrange with 20dp width from left.You can also use paddingRight, paddingBottom, paddingTop which are to give padding from right, bottom and top respectively.

Margin
Margin is outside of a View. For example if you give android:marginLeft=20dp , then the view will be arranged after 20dp from left.

Let's just suppose you have a button in a view and the size of the view is 200 by 200, and the size of the button is 50 by 50, and the button title is HT. Now the difference between margin and padding is, you can set the margin of the button in the view, for example 20 from the left, 20 from the top, and padding will adjust the text position in the button or text view etc. for example, padding value is 20 from the left, so it will adjust the position of the text.

Margin refers to the extra space outside of an element. Padding refers to the extra space within an element. The margin is the extra space around the control. The padding is extra space inside the control.

It's hard to see the difference with margin and padding with a white fill, but with a colored fill you can see it fine.

---

In simple words:
padding changes the size of the box (with something).
margin changes the space between different boxes

---

In addition to all the correct answers above, one other difference is that padding increases the clickable area of a view, whereas margins do not. This is useful if you have a smallish clickable image but want to make the click handler forgiving.

For eg, see this image of my layout with an ImageView (the Android icon) where I set the paddingBotton to be 100dp (the image is the stock launcher mipmap ic_launcher). With the attached click handler I was able to click way outside and below the image and still register a click.

In simple words:

1. Padding - creates space inside the view's border.
2. 여백-보기의 테두리 외부에 공간을 만듭니다.
