        <padding
            android:left="2dp"
            android:top="2dp"
            android:right="2dp"
            android:bottom="2dp"    >
        </padding>

        <corners
            android:radius="2dp"   >

                <gradient
                    android:angle="180"
                    android:endColor="#11B24A"
                    android:centerColor="#fec804"
                    android:startColor="#E3434B"
                    android:type="linear" />

        </shape>
    </item>

</layer-list>

我使用上面的代码作为imageview的背景我可以使用高度为8dp且宽度为1dp的视图来获取线条如何将它们放置在25％50％的正确位置。

我有一种hacky方式：

代码：

gradient_bar.xml（与你的相同）

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="0dp"
    android:layout_weight="1"
    android:layout_height="match_parent">

    <View
        android:layout_width="1dp"
        android:layout_margin="2dp"
        android:layout_height="match_parent"
        android:layout_alignParentEnd="true"
        android:background="@android:color/white"/>

</RelativeLayout>

white_line.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="0dp"
    android:layout_weight="1"
    android:layout_height="match_parent">

    <View
        android:layout_width="1dp"
        android:layout_margin="2dp"
        android:layout_height="match_parent"
        android:layout_alignParentEnd="true"
        android:background="@android:color/transparent"/>

</RelativeLayout>

<小时/> no_white_line.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <View
        android:layout_width="match_parent"
        android:layout_height="10dp"
        android:background="@drawable/gradient_bar"
        android:layout_centerVertical="true" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="10dp"
        android:orientation="horizontal"
        android:layout_centerVertical="true">

        <include layout="@layout/white_line"/>
        <include layout="@layout/white_line"/>
        <include layout="@layout/white_line"/>
        <include layout="@layout/white_line"/>
        <include layout="@layout/no_white_line"/>

    </LinearLayout>

</RelativeLayout>

activity_main.xml中

cd directory
gsed -i 's/"myValue":"[0-9]\+"/"myValue":"57"/g' *

输出：
