android shape with bottom stroke

问题描述:

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>

网友答案:

It's kind of a hack, but I think this is probably the best way to do it. The dashed line will always be on the bottom, regardless of the height.

<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="-2dp" android:right="-2dp" android:left="-2dp">
        <shape>
            <solid android:color="@android:color/transparent" />
            <stroke
                android:dashGap="10px"
                android:dashWidth="10px"
                android:width="1dp"
                android:color="#ababb2" />
        </shape>
    </item>

</layer-list>
网友答案:

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>

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" />
网友答案:

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>
网友答案:

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"
      />

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>
网友答案:

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>
