if you want to set edit icon on to circle imageview than put this below code.

 <FrameLayout
                android:layout_width="@dimen/_100sdp"
                android:layout_height="@dimen/_100sdp"
                android:layout_gravity="center"
                android:layout_marginTop="10dp">

                <de.hdodenhof.circleimageview.CircleImageView
                    android:id="@+id/profilePic"
                    android:layout_width="@dimen/_100sdp"
                    android:layout_height="@dimen/_100sdp"
                    android:layout_gravity="bottom|center_horizontal"
                    android:src="@drawable/ic_upload" />

                <de.hdodenhof.circleimageview.CircleImageView
                    android:id="@+id/iv_camera"
                    android:layout_width="@dimen/_30sdp"
                    android:layout_height="@dimen/_30sdp"
                    android:layout_gravity="top|right"
                    android:src="@drawable/edit"/>
            </FrameLayout>

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"/>

如果您希望将图像切割成圆形显示，可以这样做

public static Bitmap getCircularBitmap(Bitmap bitmap) {
        Bitmap output;

        if (bitmap.getWidth() > bitmap.getHeight()) {
            output = Bitmap.createBitmap(bitmap.getHeight(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
        } else {
            output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getWidth(), Bitmap.Config.ARGB_8888);
        }

        Canvas canvas = new Canvas(output);

        final int color = 0xff424242;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());

        float r = 0;

        if (bitmap.getWidth() > bitmap.getHeight()) {
            r = bitmap.getHeight() / 2;
        } else {
            r = bitmap.getWidth() / 2;
        }

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        canvas.drawCircle(r, r, r, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);
        return output;
    }

最佳解决方案https://www.youtube.com/watch?v=0MHoNU7ytaw 卡视图的宽度和高度决定了它所包含图像的大小设置如下:

向Gradle添加依赖项(模块) 将xml代码添加到activity.xml或fragment.xml文件中

    implementation 'androidx.cardview:cardview:1.0.0'

   <androidx.cardview.widget.CardView
      android:layout_width="300dp"
      android:layout_height="270dp"
      android:layout_gravity="center"
      app:cardCornerRadius="150dp"
      app:cardBackgroundColor="@color/trans"
      >
    <ImageView
        android:id="@+id/resultImage"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/congrats"
        android:layout_gravity="center">

    </ImageView>


  </androidx.cardview.widget.CardView>```

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" />

https://github.com/chirag-kachhadiya/RoundedImageView

简单的用法:

实现以下代码:

implementation 'com.github.chirag-kachhadiya:RoundedImageView:1.0'



 <com.infinityandroid.roundedimageview.RoundedImageView
                android:layout_width="150dp"
                android:layout_height="wrap_content"
                android:layout_margin="10dp"
                android:adjustViewBounds="true"
                android:src="@drawable/the_hundred"
                app:corner_radius="10" />

只需使用这段简单的代码: 首先添加依赖项:

implementation 'de.hdodenhof:circleimageview:2.2.0'

然后在XML布局中添加以下代码

<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"
                                        android:id="@+id/Imgshaligram"
                                        android:layout_width="96dp"
                                        android:layout_height="96dp"
                                        android:src="@drawable/shaligram"
                                        app:civ_border_color="#d1b1b1"

                                        android:foregroundGravity="center"/>
