可绘制的Android XML周围的奇怪的黑色边框

我正在绘制自定义标题以在我的应用程序中输入信息.我在xml中绘制了2个形状,然后将它们放置在布局中.然后将该布局放入我的主布局中.但是,每个包含的标题周围都有一个黑色边框.这似乎只适用于api 21设备.到底是怎么回事？

circle.xml

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/icon_background"
    android:shape="oval">
    <padding
        android:left="2dp"
        android:top="2dp"
        android:right="2dp"
        android:bottom="2dp" />
    <solid
        android:color="@color/color_primary"
        android:angle="270">
    </solid>
</shape>

line.xml

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line">
    <stroke android:width="5dp"
        android:color="@color/color_primary"/>

    <size android:height="10dp" />
</shape>

标题布局

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

    <ImageView
        android:layout_height="5dp"
        android:layout_width="match_parent"
        android:layout_alignParentStart="true"
        android:layout_marginTop="14dp"
        android:src="@drawable/line">
    </ImageView>

    <ImageView
        android:id="@+id/circle"
        android:layout_height="32dp"
        android:layout_width="32dp"
        android:src="@drawable/circle"
        android:layout_centerHorizontal="true">
    </ImageView>

    <ImageView
        android:id="@+id/header_icon"
        android:layout_height="32dp"
        android:layout_width="32dp"
        android:src="@drawable/ic_action_car"
        android:layout_centerHorizontal="true">
    </ImageView>

</RelativeLayout>

包含的布局

<RelativeLayout

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingLeft="@dimen/header_horizontal_margin"
        android:paddingRight="@dimen/header_horizontal_margin"
        android:paddingTop="@dimen/header_vertical_margin"
        android:paddingBottom="@dimen/header_vertical_margin">

        <include
            android:id="@+id/carSpecs"
            layout="@layout/header"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
        </include>

        <Spinner
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingTop="@dimen/header_vertical_margin"
            android:paddingBottom="@dimen/header_vertical_margin"
            android:layout_gravity="center_horizontal"
            android:id="@+id/vehicleSpinner"
            android:layout_below="@+id/carSpecs"/> ...

解决方法:

尝试添加此< solid android：color =“#00FFFFFF”/>在你的line.xml中.
