I would like to draw a line right in the middle of a layout and use it as a separator of other items like TextView. Is there a good widget for this. I don't really want to use an image as it would be hard to match the other components to it. And I want it to be relatively positioned as well. Thanks

Solution 1

I usually use this code to add horizontal line:

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

To add vertical separator, switch the layout_width and layout_height values

Solution 2

To improve on the answers provided by Alex Kucherenko and Dan Dar3

I added this to my styles:

<style name="Divider">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">1dp</item>
    <item name="android:background">?android:attr/listDivider</item>
</style>

Then in my layouts is less code and simpler to read.

<View style="@style/Divider"/>

Solution 3

Add this in your layout where you want the divider (modify the attributes to fit your need):

<ImageView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@android:drawable/divider_horizontal_dark"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:paddingBottom="2dp"
    android:paddingTop="2dp" />

Solution 4

You can use this in LinearLayout :

android:divider="?android:dividerHorizontal"
android:showDividers="middle"

For Example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="?android:dividerHorizontal"
    android:showDividers="middle"
    android:orientation="vertical" >            

        <TextView 
         android:layout_height="wrap_content"
         android:layout_width="wrap_content"
         android:text="abcd gttff hthjj ssrt guj"/>

        <TextView 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="abcd"/>
        <TextView 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="abcd gttff hthjj ssrt guj"/>

        <TextView 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="abcd"/>

</LinearLayout>

Solution 5

Easiest Way:

Vertical divider :

<View style="@style/Divider.Vertical"/>

Horizontal divider :

<View style="@style/Divider.Horizontal"/>

That's all yes!

Just put this in res>values>styles.xml

<style name="Divider">
    <item name="android:background">?android:attr/listDivider</item> //you can give your color here. that will change all divider color in your app.
</style>

<style name="Divider.Horizontal" parent="Divider">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">1dp</item> // You can change thickness here.

</style>

<style name="Divider.Vertical" parent="Divider">
    <item name="android:layout_width">1dp</item>
    <item name="android:layout_height">match_parent</item>
</style>

Solution 6

<TextView
    android:id="@+id/line"
    style="?android:attr/listSeparatorTextViewStyle"
    android:paddingTop="5dip"
    android:gravity="center_horizontal"
    android:layout_below="@+id/connect_help"
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000" />

Solution 7

use this code. It will help

<LinearLayout
    android:layout_width="0dip"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:divider="?android:dividerHorizontal"
    android:gravity="center"
    android:orientation="vertical"
    android:showDividers="middle" >

Solution 8

<View
            android:layout_width="2dp"
            android:layout_height="match_parent"
            android:layout_marginTop="4dp"
            android:background="@android:color/darker_gray" />

Between two Layouts Put this code to get Divider.

Solution 9

Just write this :

 android:divider="?android:dividerHorizontal"
 android:showDividers="middle"

full example:

<LinearLayout
        android:id="@+id/llTipInformation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tvServiceRating"
        android:orientation="horizontal"
        android:divider="?android:dividerHorizontal"
        android:layout_marginTop="@dimen/activity_horizontal_margin"
        android:showDividers="middle">

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/main.msg.tippercent"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/colorWhite"
            android:layout_marginTop="@dimen/activity_vertical_margin"/>
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/main.msg.tiptotal"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/colorWhite"
            android:layout_marginTop="@dimen/activity_vertical_margin"/>

</LinearLayout>

Solution 10

if you use actionBarSherlock, you can use the com.actionbarsherlock.internal.widget.IcsLinearLayout class in order to support dividers and show them between the views .

example of usage:

<com.actionbarsherlock.internal.widget.IcsLinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:divider="@drawable/divider"
    android:dividerPadding="10dp"
    android:orientation="vertical"
    android:showDividers="beginning|middle|end" >
... children...

res/drawable/divider.xml :

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

    <size android:height="2dip" />

    <solid android:color="#FFff0000" />

</shape>

do note that for some reason, the preview in the graphical designer says "android.graphics.bitmap_delegate.nativeRecycle(I)Z" . not sure what it means, but it can be ignored as it works fine on both new versions of android and old ones (tested on android 4.2 and 2.3) .

seems the error is only shown when using API17 for the graphical designer.

Solution 11

You can use this <View> element just after the First TextView.

 <View
         android:layout_marginTop="@dimen/d10dp"
         android:id="@+id/view1"
         android:layout_width="fill_parent"
         android:layout_height="1dp"
         android:background="#c0c0c0"/>

Solution 12

Adding this view; that draws a separator between your textviews

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000000" />

Solution 13

Its very simple. Just create a View with the black background color.

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000"/>

This will create a horizontal line with background color. You can also add other attributes such as margins, paddings etc just like any other view.

Solution 14

Here is your answer..this is an example to draw line between controls...

<TextView
            android:id="@+id/textView1"
            style="@style/behindMenuItemLabel1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="1dp"
            android:text="FaceBook Feeds" />

         <View
             android:layout_width="fill_parent"
             android:layout_height="2dp"
             android:background="#d13033"/>

         <ListView
            android:id="@+id/list1"
            android:layout_width="350dp"
            android:layout_height="50dp" />

This code draw line between two controls...

Solution 15

It adds a horizontal divider to anywhere in your layout.

    <TextView
       style="?android:listSeparatorTextViewStyle"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"/>

Solution 16

Runtime version:

View dividerView = new View(getContext());
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
    ViewGroup.LayoutParams.FILL_PARENT, UIUtils.dpToPix(getContext(), 1));
dividerView.setLayoutParams(lp);

TypedArray array = getContext().getTheme()
    .obtainStyledAttributes(new int[] {android.R.attr.listDivider});
Drawable draw = array.getDrawable(0);       
array.recycle();

dividerView.setBackgroundDrawable(draw);
mParentLayout.addView(dividerView);

Solution 17

use this xml code to add vertical line

 <View
    android:layout_width="1dp"
    android:layout_height="match_parent"
    android:layout_centerVertical="true"
    android:background="#000000" />

use this xml code to add horizontal line

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000000" />

Solution 18

//for vertical line:

<View
   android:layout_width="1dp"
   android:layout_height="fill_parent"
   android:background="#00000000" />




//for horizontal line: 

<View
   android:layout_width="fill_parent"
   android:layout_height="1dp"
   android:background="#00000000" />
//it works like a charm

Solution 19

In cases where one is using android:layout_weight property to assign available screen space to layout components, for instance

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:orientation="vertical">
        ...
        ...
    </LinearLayout>

     /* And we want to add a verical separator here */

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:orientation="vertical">
        ...
        ...
     </LinearLayout>

</LinearLayout>

To add a separator between the existing two layouts which has taken the entire screen space already, we cannot just add another LinearLayout with android:weight:"1" because that will make three equal width columns which we don't want. Instead, we will decrease the amount of space we will be giving to this new layout. Final code would look like this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:orientation="vertical">
        ...
        ...
    </LinearLayout>

                    /* *************** ********************** */

    /* Add another LinearLayout with android:layout_weight="0.01" and 
       android:background="#your_choice" */
    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.01"
        android:background="@android:color/darker_gray"
     />

    /* Or View can be used */
    <View
        android:layout_width="1dp"
        android:layout_height="match_parent"
        android:layout_marginTop="16dp"
        android:background="@android:color/darker_gray"
     />

                     /* *************** ********************** */

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:orientation="vertical">
        ...
        ...
    </LinearLayout>

</LinearLayout>

Solution 20

If you are going to use it a lot, best thing to do is

styles.xml:

<style name="Seperator">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">1dp</item>
        <item name="android:background">@color/light_color</item>
    </style>

now in your layout, just add it like:

<View style="@style/Seperator" />

Solution 21

To complete Camille Sévigny answer you can additionally define your own line shape for example to custom the line color.

Define an xml shape in drawable directory. line_horizontal.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto" android:shape="line">
    <stroke android:width="2dp" android:color="@android:color/holo_blue_dark" />
    <size android:width="5dp" />
</shape>

Use this line in your layout with the wished attributes:

    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="2dp"
        android:paddingLeft="5dp"
        android:paddingRight="5dp"
        android:paddingTop="2dp"
        android:src="@drawable/line_horizontal" />

Solution 22

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="2dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:paddingTop="2dp"
    android:scaleType="fitXY"
    android:src="?android:attr/listDivider" />

Solution 23

Add a horizontal black line using this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000000"
    android:layout_marginTop="10dp"/>

Solution 24

I usually use this code:

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:layout_alignParentLeft="true"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    android:layout_marginTop="10dp"
    android:background="#aa000000" />

if you have an object in your layout and you want set line below that use this attribute in ImageView:

android:layout_below="@+id/textBox1"

Solution 25

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item
    android:bottom="0dp"
    android:left="-2dp"
    android:right="-2dp"
    android:top="-2dp">
    <shape android:shape="rectangle">
        <stroke
            android:width="1dp"
            android:color="@color/divider" />
    </shape>
</item>

Solution 26

This would help you to resolve this problem. Here a small view is created to make a black line as a separator between two views.

 <View
        android:layout_width="3dp"
        android:layout_height="wrap_content"
        android:background="@android:color/black"
         />

Solution 27

Here is the code " a horizontal divider line between two Text Views". Try this

    <TextView
        android:id="@id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="5dp"
        android:inputType="textPersonName"
        android:text:"address" />


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


    <TextView
        android:id="@id/textView7"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textPersonName" 
        android:text:"Upload File" />/>

Solution 28

Divide the space in two equal parts:

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:divider="?android:dividerHorizontal"
        android:showDividers="end"></LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"></LinearLayout>

</LinearLayout>

Notice that one part contains a divider at the end

Solution 29

Simple solution

just add this code in your layout and replace 'Id_of__view_present_above' to the id of the view, below which you need the divider.

<TextView
  android:layout_width="match_parent"
  android:layout_height="1dp"
  android:background="#c0c0c0"
  android:id="@+id/your_id"
  android:layout_marginTop="16dp" 
  android:layout_below="@+id/Id_of__view_present_above"
/>

Solution 30

For example if you used recyclerView for yours items:

in build.gradle write:

dependencies {
    compile 'com.yqritc:recyclerview-flexibledivider:1.4.0'

If you want to set color, size and margin values, you can specify as the followings:

RecyclerView recyclerView = (RecyclerView) 
findViewById(R.id.recyclerview);
recyclerView.addItemDecoration(
        new HorizontalDividerItemDecoration.Builder(this)
                .color(Color.RED)
                .sizeResId(R.dimen.divider)
                .marginResId(R.dimen.leftmargin, R.dimen.rightmargin)
                .build());
