Android 레이아웃 가중치

Android 레이아웃 가중치

---

저는 Android 개발이 처음이고 선형 레이아웃에서 가중치를 설정하는 것에 대해 질문이 있습니다.

두 개의 사용자 지정 단추와 사용자 지정 편집 텍스트가있는 행을 만들려고합니다. 편집 텍스트는 내용만큼만 공간을 차지해야하며 두 개의 버튼은 행에서 사용 가능한 나머지 공간을 채우기 위해 가로로 확장되어야합니다. 이렇게 ...

| [#Button++#] [#Button--#] [et] |

여러 번 시도한 후에는 지나치게 복잡해 보이지만 원하는 것에 가장 가깝습니다.

| [Button] [Button] [###ET###] |

            android:maxWidth="50sp"
            android:background="@drawable/tv_black_background3"
            android:textColorHighlight="#c30505"
            ></EditText>
    </LinearLayout>
</LinearLayout>

내가 이해했듯이 버튼을 잡고있는 선형 레이아웃에 대해 [android : layout_weight = "2"]를 설정하면 편집 텍스트보다 더 많은 공간을 차지하게되지만, 저에게는 그 반대가되어 둘 다 크기가 절반으로 줄어 듭니다.

나는 너무 많은 다른 조합을 시도하여 기억조차 할 수 없으며 아무도 작동하지 않았습니다.

It doesn't work because you are using fill_parent as the width. The weight is used to distribute the remaining empty space or take away space when the total sum is larger than the LinearLayout. Set your widths to 0dip instead and it will work.

---

android:Layout_weight can be used when you don't attach a fix value to your width already like fill_parent etc.

Do something like this :

<Button>

Android:layout_width="0dp"
Android:layout_weight=1

-----other parameters
</Button>

---

Think it that way, will be simpler

If you have 3 buttons and their weights are 1,3,1 accordingly, it will work like table in HTML

Provide 5 portions for that line: 1 portion for button 1, 3 portion for button 2 and 1 portion for button 1

---

In the linearLayout set the WeightSum=2;

And distribute the weight to its childs as you want them to display.. I have given weight ="1" to the child .So both will distribute half of the total.

 <LinearLayout
    android:id="@+id/linear1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="2"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/ring_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ring_oss" />

    <ImageView
        android:id="@+id/maila_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/maila_oss" />
</LinearLayout>

weight values 0-1 share distribution of available space (after setting layout_width="0px") in proportion to the weight value. View elements with weight not specified (no weight entry) get weight 0 which means they get no expansion.

A simple alternative with no weight entries needed is to attach marquee to a view with text which tells it to expand from minimum needed for the text (wrap_content) to space available EditText: android:layout_width="wrap_content" android:ellipsize="marquee"

---

i would suppose to set the EditTexts width to wrap_content and put the two buttons into a LinearLayout whose width is fill_parent and weight set to 1.

---

One more reason I found (vague as it may sound). The below did not work.

LinearLayout vertical

LinearLayout height fillparent + weight

LinearLayout height fillparent + weight

LinearLayout height fillparent + weight

EndLinearLayout

What did work was

RelativeLayout

LinearLayout vertical

LinearLayout height fillparent + weight

LinearLayout height fillparent + weight

LinearLayout height fillparent + weight

EndLinearLayout

EndRelativeLayout

It sounds vague by a root layout with Linear and weights under it did not work. And when I say "did not work", I mean, that after I viewed the graphical layout between various resolutions the screen consistency broke big time.

<LinearLayout
    android:id="@+id/linear1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="9"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/ring_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/ring_oss" />

    <ImageView
        android:id="@+id/maila_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/maila_oss" />
<EditText
        android:id="@+id/edittxt"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/maila_oss" />
</LinearLayout>
