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"/>

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'

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" />

    app:srcCompat="@drawable/ic_bg_picture"/>

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" />

我用shape = "oval"代替下面的"ring"。这对我很有效。为了保持图像在边界内，我使用<padding>并在<ImageView>中设置<adjustViewBounds>为true。我尝试过大小在50 x 50 px到200x200 px之间的图像。

创建一个CustomImageview，然后简单地覆盖它的onDraw()方法如下:

@Override
protected void onDraw(Canvas canvas) {

    float radius = this.getHeight()/2;
    Path path = new Path();
    RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
    path.addRoundRect(rect, radius, radius, Path.Direction.CW);
    canvas.clipPath(path);
    super.onDraw(canvas);

}

如果你想要的代码自定义小部件以及:-

CircularImageView.java

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

import androidx.annotation.Nullable;

public class CircularImageView extends ImageView {

    private Drawable image;

    public CircularImageView(Context context) {
        super(context);

        init(null, 0);
    }

    public CircularImageView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);

        init(attrs, 0);
    }

    public CircularImageView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

        init(attrs, defStyleAttr);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        float radius = this.getHeight()/2;
        Path path = new Path();
        RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
        path.addRoundRect(rect, radius, radius, Path.Direction.CW);
        canvas.clipPath(path);
        super.onDraw(canvas);

    }

    private void init(AttributeSet attrs, int defStyle) {
        TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
        try {
            image = a.getDrawable(R.styleable.CircularImageView_src);
        } finally {
            a.recycle();
        }

        this.setImageDrawable(image);
    }
}

此外，在res/attrs.xml中添加以下代码来创建所需的属性

<declare-styleable name="CircularImageView">
        <attr name="src" format="reference" />
</declare-styleable>
