[android] Style bottom Line in Android

I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center. Does anyone know how to get it right? the stroke needs to be the bottom line/border. I am using the shape as a background to a TextView. Please, never mind why I need it.

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

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#1bd4f6" />
        </shape>
    </item>

    <item>
        <shape android:shape="line" >
            <padding android:bottom="1dp" />

            <stroke
                android:dashGap="10px"
                android:dashWidth="10px"
                android:width="1dp"
                android:color="#ababb2" />
        </shape>
    </item>

</layer-list>

Try next xml drawable code:

    <layer-list>
        <item android:top="-2dp" android:right="-2dp" android:left="-2dp">
            <shape>
                <solid android:color="@android:color/transparent" />
                <stroke
                    android:width="1dp"
                    android:color="#fff" />
            </shape>
        </item>
    </layer-list>

This does the trick...

<item >
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BOTTOM_LINE_COLOR"/>
    </shape>
</item>

<item android:bottom="1.5dp">
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BG_COLOR"/>
    </shape>
</item>

A Simple solution :

Create a drawable file as edittext_stroke.xml in drawable folder. Add the below code:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line"
   >
    <stroke
        android:width="1dp"
        android:color="@android:color/white" >
    </stroke>
</shape>

In layout file , add the drawable to edittext as

android:drawableBottom="@drawable/edittext_stroke"

<EditText
      android:textColor="@android:color/white"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:drawableBottom="@drawable/edittext_stroke"
      />

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:top="-6dp"
        android:left="-6dp"
        android:right="-6dp"
        android:bottom="0dp">

        <shape android:shape="rectangle">
            <solid android:color="#88FFFF00"/>
            <stroke
                android:width="5dp"
                android:color="#FF000000"/>
        </shape>
    </item>
</layer-list>

it is completely transparent Edittext with transparent background.

<item>
    <shape android:shape="rectangle" >
        <solid android:color="@color/transparent" />
    </shape>
</item>

<item android:top="-3dp" android:right="-3dp" android:left="-3dp">
    <shape>
        <solid android:color="@android:color/transparent" />
        <stroke

            android:width="2dp"
            android:color="@color/bottomline" />
    </shape>
</item>

Usually for similar tasks - I created layer-list drawable like this one:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
        <solid android:color="@color/underlineColor"/>
        </shape>
    </item>
<item android:bottom="3dp">
    <shape android:shape="rectangle">
        <solid android:color="@color/buttonColor"/>
    </shape>
</item>

The idea is that first you draw the rectangle with underlineColor and then on top of this one you draw another rectangle with the actual buttonColor but applying bottomPadding. It always works.

But when I needed to have buttonColor to be transparent I couldn't use the above drawable. I found one more solution

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent"/>
    </shape>
</item>

<item android:drawable="@drawable/white_box" android:gravity="bottom"     android:height="2dp"/>
</layer-list>

(as you can see here the mainButtonColor is transparent and white_box is just a simple rectangle drawable with white Solid)

A Simple solution :

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:bottom="-1dp"
        android:left="-1dp"
        android:right="-1dp"
        android:top="-1dp">

        <shape android:shape="rectangle">

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

            <stroke
                android:width="5dp"
                android:color="@android:color/red"
                android:dashWidth="10dp"
                android:dashGap="12dp" />

        </shape>
    </item>
</layer-list>

And finally we have something like that :)

I think you do not need to use shape if I understood you.

If you are looking as shown in following image then use following layout.

<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" >

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:background="#1bd4f6"
    android:paddingBottom="4dp" >

    <TextView
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:background="#ababb2"
        android:padding="5dp"
        android:text="Hello Android" />
 </RelativeLayout>

 </RelativeLayout>

EDIT

play with these properties you will get result

    android:top="dimension"
    android:right="dimension"
    android:bottom="dimension"
    android:left="dimension"

try like this

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

<item>
    <shape android:shape="rectangle" >
        <solid android:color="#1bd4f6" />
    </shape>
</item>

<item android:top="20px"
    android:left="0px">
    <shape android:shape="line"  >
        <padding android:bottom="1dp" />

        <stroke
            android:dashGap="10px"
            android:dashWidth="10px"
            android:width="1dp"
            android:color="#ababb2" />
    </shape>
</item>

</layer-list>

easiest way to do this is put after that view where you want bottom border

    <?xml version="1.0" encoding="utf-8"?>
    <View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/colorPrimary" />

use this xml change the color with your choice.

<item>
    <layer-list>
        <item>
            <shape>
                <solid android:color="@color/gray_500" />

            </shape>
        </item>
        <!-- CONTENT LAYER -->
        <item android:bottom="2dp" >
            <shape>
                <solid android:color="#ffffff" />
            </shape>
        </item>
    </layer-list>
</item>

In Case if you want programmatically

public static Drawable getStorkLineDrawable(@ColorInt int colorStrok, int    iSize, int left, int top, int right, int bottom)

{
    GradientDrawable gradientDrawable = new GradientDrawable();
    gradientDrawable.setShape(GradientDrawable.RECTANGLE);
    gradientDrawable.setStroke(iSize, colorStrok);
    LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
    layerDrawable.setLayerInset(0, left, top, right, bottom);
    return layerDrawable;
}

call this method like

  Drawable yourLineDrawable=  getStorkLineDrawable(yourColor, iSize, -iSize, -iSize, -iSize, 0);

I feel it is straightforward, without all this negative paddings or storks.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@color/main_bg_color"/>
    <item android:gravity="bottom">
        <shape android:shape="rectangle">
            <size android:height="5dp"/>
            <solid android:color="@color/bottom_bar_color"/>
        </shape>
    </item>
</layer-list>

This worked best for me:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="-5dp" android:left="-5dp" android:right="-5dp" android:bottom="0dp">
        <shape android:shape="rectangle">
            <stroke android:width="4dp" android:color="#ff0000"/>
        </shape>
    </item>
</layer-list>

Shows the line on the bottom only. You can easily change with stroke width to size you like and also update the top, left, right on the accordingly.

This answer is for those google searchers who want to show dotted bottom border of EditText like here

Create dotted.xml inside drawable folder and paste these

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle">
            <stroke
                android:width="0.5dp"
                android:color="@android:color/black" />    
            <solid android:color="#ffffff" />
            <stroke
                android:width="1dp"
                android:color="#030310"
                android:dashGap="5dp"
                android:dashWidth="5dp" />
            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />
        </shape>
    </item>
</layer-list>

Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Some Text"
    android:background="@drawable/dotted" />
