Question

我不擅长编码，但是当涉及到在android中设计部分时，我总是无法实现它。渐变色在垂直方向工作但不在水平方向。任何人都可以建议我如何在水平线上将这些分隔线放到整个项目中，就像在垂直线上一样？

我的divider.xml

   <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

<gradient
    android:angle="0"
    android:endColor="@android:color/white"
    android:centerColor="#000"
    android:startColor="@android:color/white"
    android:type="linear" />

</shape>

Answer 1

如何使用line代替？：

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



<item android:top="-5dp" android:right="-5dp" android:left="-5dp">
    <shape>
        <stroke android:color="@android:color/transparent" />
        <stroke
            android:width=".8dp"
            android:color="@color/black" />

    </shape>

</item>

上面的垂直分隔符，这个是水平分隔符：

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



    <item android:top="-5dp" android:bottom="-5dp" android:left="-5dp">
        <shape>
            <stroke android:color="@android:color/transparent" />
            <stroke
                android:width=".8dp"
                android:color="@color/company_color" />

        </shape>

    </item>

</layer-list>

尝试自己的宽度。

或从当前分隔符android:centerColor="#000"

中删除此行

我们可以使用imageView通过将其背景设置为渐变来实现此目的。试试这个：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
        <gradient
            android:endColor="@android:color/transparent"
            android:centerColor="#000"
            android:startColor="@android:color/transparent"
            android:angle="0"
            android:type="linear"/>
    </shape>

然后像这样设置imageView的背景：

<ImageView
        android:id="@+id/hr"
        android:layout_width="match_parent"
        android:layout_height="3dp"
        android:background="@drawable/background_gradient"
        android:gravity="center_horizontal"
        />

如何显示水平和垂直渐变分割线？
