2021年更新:使用Glide v4 CircleCrop参见https://bumptech.github.io/glide/doc/generatedapi.html

    implementation 'com.github.bumptech.glide:glide:4.11.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'

XML

<ImageView
    android:id="@+id/vinyl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:ignore="ContentDescription" />

在代码中

    Glide.with(this)
            .load("https://images.pexels.com/photos/3828241/pexels-photo-3828241.jpeg")
            .transform(CircleCrop())
            .into(rootView.findViewById<ImageView>(R.id.vinyl))

只需使用这些代码行，你就完成了:

<de.hdodenhof.circleimageview.CircleImageView
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:clickable="true"
            app:civ_border_width="3dp"
            app:civ_border_color="#FFFFFFFF"
            android:id="@+id/profile"
            android:layout_width="200dp"
            android:layout_height="200dp"
            android:layout_below="@+id/header_cover_image"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="-130dp"
            android:elevation="5dp"
            android:padding="20dp"
            android:scaleType="centerCrop"
            android:src="@drawable/profilemain" />

别忘了导入:

import de.hdodenhof.circleimageview.CircleImageView;

在构建中添加此库。gradle:

compile 'de.hdodenhof:circleimageview:2.1.0'

你可以简单地使用AndroidX ImageFilterView。

 <androidx.constraintlayout.utils.widget.ImageFilterView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_marginStart="@dimen/margin_medium"
        android:layout_marginBottom="@dimen/margin_medium"
        android:background="@color/white"
        android:padding="@dimen/margin_small"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:roundPercent="1"
        app:srcCompat="@drawable/ic_gallery" />

我是这样做的，我在矢量图像中使用了背景色

ic_bg_picture.xml

 <vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="100dp"
    android:height="100dp"
    android:viewportWidth="100"
    android:viewportHeight="100">
  <path
      android:pathData="M100.6,95.5c0,-0.4 -0.1,-0.7 0,-1.1c-0.2,-0.7 -0.2,-1.4 -0.1,-2.1c0,-0.1 0,-0.2 0,-0.3c-0.1,-0.6 -0.1,-1.2 0,-1.8c-1,-1.3 -0.3,-2.9 -0.3,-4.3c-0.1,-28.7 -0.1,-57.3 -0.1,-86C68,-0.1 35.9,-0.1 3.8,-0.2C0.7,-0.2 0,0.5 0,3.6c0.1,32.1 0.1,64.2 0.1,96.2c31,0 62,-0.1 92.9,0.1c3.6,0 6.3,-0.2 7.5,-3.2C100.5,96.4 100.5,95.9 100.6,95.5zM46.3,95.2C26.4,94 2,74.4 3.8,46.8C5.1,27.2 24.4,2.7 52.6,4.6c20.2,1.4 43,21.3 41.5,45.1C96.1,72.4 73,96.8 46.3,95.2z"
      android:fillColor="#6200EE"/>
</vector>

在我的情况下，我创建了一个向量，并更改android:fillColor="#6200EE"

通过我背景的颜色

  <ImageView
    android:id="@+id/iv_profile_image"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:contentDescription="@string/app_name"
    app:srcCompat="@color/colorPrimaryDark" />

<ImageView
    android:id="@+id/container_profile_image"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:contentDescription="@string/app_name"
    app:srcCompat="@drawable/ic_bg_picture"/>

另外，这两个库可以帮助您。

https://github.com/vinc3m1/RoundedImageView

实现以下代码:

implementation 'com.makeramen:roundedimageview:2.3.0'

简单的用法:

<com.makeramen.roundedimageview.RoundedImageView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/imageView1"
        android:src="@drawable/photo1"
        android:scaleType="fitCenter"
        app:riv_corner_radius="30dip"
        app:riv_border_width="2dip"
        app:riv_border_color="#333333"
        app:riv_mutate_background="true"
        app:riv_tile_mode="repeat"
        app:riv_oval="true" />
