Question

我有圆形imageview，我需要在cardview上方对齐，但它应该像图像的半圈将在cardview之外并保留图像的半圈在cardview内。与cardview的顶部边框中心一样，其上会显示圆形imageview。

我怎么能这样做，我将无法上传图片，因为我的代理人不会因为不便而抱歉。

Answer 1

试试这段代码

<android.support.design.widget.FloatingActionButton
    android:id="@+id/btn_contacts"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:scaleType="center"
    android:src="@drawable/ic_contacts_36px"
    app:fabSize="normal"
    app:layout_anchor="@id/ll_cardView"
    app:layout_anchorGravity="center|top" />

将app：layout_anchor id名称更改为您的卡片视图ID。

这可以这样做。

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    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"
    tools:context="com.simplebox.demo.MainActivity">

    <android.support.v7.widget.CardView
        android:id="@+id/first"
        app:cardBackgroundColor="@android:color/white"
        app:cardCornerRadius="@dimen/cardview_default_radius"
        app:cardElevation="4dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        card_view:cardUseCompatPadding="true">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="300dp"
            android:background="#FFF000">
        </RelativeLayout>
    </android.support.v7.widget.CardView>

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_gravity="center_horizontal"
        android:background="#000000"
        android:contentDescription="@null" />

</FrameLayout>

输出将是。使用圆形ImageView进行圆形图像。

Answer 3

执行以下操作

<FrameLayout>

    <CardView> //set marginTop of 10 dp so that it will be half the height of CirccularImageView

    <CircularImageView> //set some height to it like 20dp and gravity center horizontal.
</FrameLayout>
