수평 LinearLayout에 (수직) 구분선을 추가하는 방법은 무엇입니까?

수평 LinearLayout에 (수직) 구분선을 추가하는 방법은 무엇입니까?

---

수평 선형 레이아웃에 구분선을 추가하려고하는데 아무데도 없습니다. 구분선이 표시되지 않습니다. 저는 Android를 사용하는 완전히 초보자입니다.

이것은 내 레이아웃 XML입니다.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <LinearLayout 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/llTopBar"
        android:orientation="horizontal"
        android:divider="#00ff00"
        android:dividerPadding="22dip"
        android:showDividers="middle"
       >

        <Button
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:text="asdf" />
            <Button
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:text="asdf"
             />

    </LinearLayout>

</RelativeLayout>

수평 구분선에 사용

<View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:background="@color/honeycombish_blue" />

그리고 이것은 수직 분할기

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/honeycombish_blue" />

또는 수평 구분선을 위해 LinearLayout 구분선을 사용할 수있는 경우

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:height="1dp"/>
    <solid android:color="#f6f6f6"/>
</shape>

그리고 LinearLayout에서

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@drawable/divider"
    android:orientation="vertical"
    android:showDividers="middle" >

세로 구분선을 android:height="1dp"사용하려면 모양 대신 사용하십시오.android:width="1dp"

팁 : 음주 잊지android:showDividers 항목을 선택합니다.

이것을 시도하고 res/drawable폴더에 구분선을 만듭니다 .

vertical_divider_1.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">    
    <size android:width="1dip" />
    <solid android:color="#666666" />    
</shape> 

다음과 divider같이 LinearLayout 의 속성을 사용합니다 .

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="48dp"
    android:orientation="horizontal"
    android:divider="@drawable/vertical_divider_1"
    android:dividerPadding="12dip"
    android:showDividers="middle"
    android:background="#ffffff" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />
    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</LinearLayout>

참고 : android:divider Android 3.0 (API 레벨 11) 이상에서만 사용할 수 있습니다.

It is easy to add divider to layout, we don't need a separate view.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:divider="?android:listDivider"
    android:dividerPadding="2.5dp"
    android:orientation="horizontal"
    android:showDividers="middle"
    android:weightSum="2" ></LinearLayout>

Above code make vertical divider for LinearLayout

Update: pre-Honeycomb using AppCompat

If you are using the AppCompat library v7 you may want to use the LinearLayoutCompat view. Using this approach you can use drawable dividers on Android 2.1, 2.2 and 2.3.

Example code:

<android.support.v7.widget.LinearLayoutCompat
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:showDividers="middle"
        app:divider="@drawable/divider">

drawable/divider.xml: (divider with some padding on the top and bottom)

<?xml version="1.0" encoding="UTF-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
        android:insetBottom="2dp"
        android:insetTop="2dp">
    <shape>
        <size android:width="1dp" />
        <solid android:color="#FFCCCCCC" />
    </shape>
</inset>

Very important note: The LinearLayoutCompat view does not extend LinearLayout and therefor you should not use the android:showDividers or android:divider properties but the custom ones: app:showDividers and app:divider. In code you should also use the LinearLayoutCompat.LayoutParams not the LinearLayout.LayoutParams!

I just ran into the same problem today. As the previous answers indicate, the problem stems from the use of a color in the divider tag, rather than a drawable. However, instead of writing my own drawable xml, I prefer to use themed attributes as much as possible. You can use the android:attr/dividerHorizontal and android:attr/dividerVertical to get a predefined drawable instead:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:showDividers="middle"
    android:divider="?android:attr/dividerVertical"
    android:orientation="horizontal">
    <!-- other views -->
</LinearLayout>

The attributes are available in API 11 and above.

Also, as mentioned by bocekm in his answer, the dividerPadding property does NOT add extra padding on either side of a vertical divider, as one might assume. Instead it defines top and bottom padding and thus may truncate the divider if it's too large.

---

You can use the built in divider, this will work for both orientations.

<LinearLayout
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:divider="?android:attr/listDivider"
  android:orientation="horizontal"
  android:showDividers="middle">

---

Frustratingly, you have to enable showing the dividers from code in your activity. For example:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set the view to your layout
    setContentView(R.layout.yourlayout);

    // Find the LinearLayout within and enable the divider
    ((LinearLayout)v.findViewById(R.id.llTopBar)).
        setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);

}

---

Your divider may not be showing due to too large dividerPadding. You set 22dip, that means the divider is truncated by 22dip from top and by 22dip from bottom. If your layout height is less than or equal 44dip then no divider is visible.

In order to get drawn, divider of LinearLayout must have some height while ColorDrawable (which is essentially #00ff00 as well as any other hardcoded color) doesn't have. Simple (and correct) way to solve this, is to wrap your color into some Drawable with predefined height, such as shape drawable

If the answer of Kapil Vats is not working try something like this:

drawable/divider_horizontal_green_22.xml

    <size android:width="22dip"/>
    <solid android:color="#00ff00"/>

</shape>

layout/your_layout.xml

LinearLayout 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/llTopBar"
            android:orientation="horizontal"
            android:divider="@drawable/divider_horizontal_green_22"
            android:showDividers="middle"
           >

I encountered an issue where the padding attribute wasn't working, thus I had to set the height of the divider directly in the divider.

Note:

If you want to use it in vertical LinearLayout, make a new one, like this: drawable/divider_vertical_green_22.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
        xmlns:android="http://schemas.android.com/apk/res/android">

    <size android:height="22dip"/>
    <solid android:color="#00ff00"/>

</shape>

You have to create the any view for separater like textview or imageview then set the background for that if you have image else use the color as the background.

Hope this helps you.
