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>

试试这个。

public class RoundedImageView extends android.support.v7.widget.AppCompatImageView {

    private int borderWidth = 4;
    private int viewWidth;
    private int viewHeight;
    private Bitmap image;
    private Paint paint;
    private Paint paintBorder;
    private BitmapShader shader;

    public RoundedImageView(Context context)
    {
        super(context);
        setup();
    }

    public RoundedImageView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        setup();
    }

    public RoundedImageView(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        setup();
    }

    private void setup()
    {
        paint = new Paint();
        paint.setAntiAlias(true);

        paintBorder = new Paint();
        setBorderColor(Color.WHITE);
        paintBorder.setAntiAlias(true);
        this.setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);

        paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.WHITE);
    }

    public void setBorderWidth(int borderWidth)
    {
        this.borderWidth = borderWidth;
        this.invalidate();
    }

    public void setBorderColor(int borderColor)
    {
        if (paintBorder != null)
            paintBorder.setColor(borderColor);

        this.invalidate();
    }

    private void loadBitmap()
    {
        BitmapDrawable bitmapDrawable = (BitmapDrawable) this.getDrawable();

        if (bitmapDrawable != null)
            image = bitmapDrawable.getBitmap();
    }

    @SuppressLint("DrawAllocation")
    @Override
    public void onDraw(Canvas canvas)
    {
        loadBitmap();

        if (image != null)
        {
            shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvas.getWidth(), canvas.getHeight(), false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
            paint.setShader(shader);
            int circleCenter = viewWidth / 2;
            canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter + borderWidth - 4.0f, paintBorder);
            canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter - 4.0f, paint);
        }
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        int width = measureWidth(widthMeasureSpec);
        int height = measureHeight(heightMeasureSpec, widthMeasureSpec);

        viewWidth = width - (borderWidth * 2);
        viewHeight = height - (borderWidth * 2);

        setMeasuredDimension(width, height);
    }

    private int measureWidth(int measureSpec)
    {
        int result = 0;
        int specMode = MeasureSpec.getMode(measureSpec);
        int specSize = MeasureSpec.getSize(measureSpec);

        if (specMode == MeasureSpec.EXACTLY)
        {
            result = specSize;
        }
        else
        {
            // Measure the text
            result = viewWidth;
        }

        return result;
    }

    private int measureHeight(int measureSpecHeight, int measureSpecWidth)
    {
        int result = 0;
        int specMode = MeasureSpec.getMode(measureSpecHeight);
        int specSize = MeasureSpec.getSize(measureSpecHeight);

        if (specMode == MeasureSpec.EXACTLY)
        {
            result = specSize;
        }
        else
        {
            result = viewHeight;
        }

        return (result + 2);
     }
 }

然后在布局中使用这个ImageView:

<com.app.Demo.RoundedImageView
     android:id="@+id/iv_profileImage"
     android:layout_width="70dp"
     android:layout_height="70dp"
     android:layout_centerHorizontal="true"
    />

您不需要任何第三方库。

你可以在材质中使用ShapeableImageView。

implementation 'com.google.android.material:material:1.2.0'

style.xml

<style name="ShapeAppearanceOverlay.App.CornerSize">
     <item name="cornerSize">50%</item>
</style>

在布局

<com.google.android.material.imageview.ShapeableImageView
     android:layout_width="100dp"
     android:layout_height="100dp"
     app:srcCompat="@drawable/ic_profile"
     app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.App.CornerSize"
/>

你们可以看到

https://developer.android.com/reference/com/google/android/material/imageview/ShapeableImageView

或者这个

https://medium.com/android-beginners/shapeableimageview-material-components-for-android-cac6edac2c0d

使用材质组件库只需使用ShapeableImageView。 Somethig:

<com.google.android.material.imageview.ShapeableImageView
    app:shapeAppearanceOverlay="@style/roundedImageViewRounded"
    app:strokeColor="@color/....."
    app:strokeWidth="1dp"
    ...
    />

:

  <style name="roundedImageViewRounded">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>
  </style>

注意:它至少需要1.2.0版本。

使用jetpack合成，你可以使用CircleShape应用剪辑修饰器:

Image(
    painter = painterResource(R.drawable.xxxx),
    contentDescription = "xxxx",
    contentScale = ContentScale.Crop,
    modifier = Modifier
        .size(100.dp)
        .clip(CircleShape)
        .border(2.dp, Color.Blue, CircleShape)
)

你可以做一个简单的圆，有白色边框，透明内容的形状。

// res/drawable/circle.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:innerRadius="0dp"
    android:shape="ring"
    android:thicknessRatio="1.9"
    android:useLevel="false" >
    <solid android:color="@android:color/transparent" />

    <stroke
        android:width="10dp"
        android:color="@android:color/white" />
</shape>

然后制作一个可绘制的图层列表，并将其作为imageview的背景。

// res/drawable/img.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:drawable="@drawable/circle"/>    
    <item android:drawable="@drawable/ic_launcher"/>

</layer-list>

把它作为imageview的背景。

   <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/img"/>

你会得到类似的东西。

实际上，你可以使用谷歌提供的支持库RoundedBitmapDrawableFactory类(这里和这里)，而不是使用第三方库:

Gradle:

implementation 'androidx.appcompat:appcompat:1.0.0-beta01'

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
        val bitmap = convertDrawableToBitmap(originalDrawable)
        val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
        drawable.setAntiAlias(true)
        drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
        avatarImageView.setImageDrawable(drawable)
    }

    companion object {
        @JvmStatic
        fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
            if (drawable is BitmapDrawable)
                return drawable.bitmap
            // We ask for the bounds if they have been set as they would be most
            // correct, then we check we are  > 0
            val bounds = drawable.bounds
            val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
            val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
            // Now we check we are > 0
            val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
                    Bitmap.Config.ARGB_8888)
            val canvas = Canvas(bitmap)
            drawable.setBounds(0, 0, canvas.width, canvas.height)
            drawable.draw(canvas)
            return bitmap
        }
    }
}

xml res - - activity_main布局。

<FrameLayout

结果:

并且，假设你想在它上面添加一个边框，你可以使用下面的例子:

stroke_drawable.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <stroke
        android:width="4dp" android:color="@android:color/black"/>
</shape>

并添加android:前台="@drawable/stroke_drawable"到布局XML文件中的ImageView，你会得到这个:

不过，我不确定如何添加阴影(这将适用于较旧的Android版本)。使用FloatingActionButton(从“com.google.android. button”材料:材料"依赖)，我未能使位图填充FAB本身。如果它能起作用，那么使用它会更好。

编辑:如果你想添加立面阴影(可从API 21)，你可以改变一点我写的:

在布局XML文件内部:

<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
    android:id="@+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
    android:layout_gravity="center" android:background="@drawable/stroke_drawable" tools:srcCompat="@drawable/avatar_1"/>

CircularShadowViewOutlineProvider.kt

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
    override fun getOutline(view: View, outline: Outline) {
        val size = Math.max(view.width, view.height)
        outline.setRoundRect(0, 0, size, size, size / 2f)
    }
}

在代码:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()

结果:
