I have two circular image view, one is containing the profile pic and other is for the camera. Following is my XML file:

这给了我以下设计：
I want to add a camera icon like the following image:
我想添加一个像下图这样的相机图标：
CircularImageView.java
圆形图像视图.java
public class CircularImageView extends ImageView {
public CircularImageView(Context ctx, AttributeSet attrs) {
super(ctx, attrs);
}
@Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
Bitmap
finalBitmap;
if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
false);
else
finalBitmap = bitmap;
Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
finalBitmap.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
finalBitmap.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(finalBitmap.getWidth() / 2 + 0.7f,
finalBitmap.getHeight() / 2 + 0.7f,
finalBitmap.getWidth() / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(finalBitmap, rect, rect, paint);
return output;
}
}
How can I add a camera icon inside the circular image view? If I am setting the camera icon in the background, only the camera icon is displayed. No circular image view is there.
如何在圆形图像视图中添加相机图标？如果我在后台设置相机图标，则只显示相机图标。没有圆形图像视图。
After using the following code :
使用以下代码后：
<com.almabay.almachat.circularImageView.CircularImageView
android:id="@+id/iv_camera"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="top|right"
android:layout_marginTop="@dimen/margin30"
android:background="@drawable/color"
android:src="@drawable/camera" />
I am getting the following screen:

You're using a library for Circular ImageView. So you need to check if there's any attribute to set an icon inside the ImageView. Anyway, here's how you can achieve the desired behaviour. You can add an image with the camera icon inside instead of setting a background colour.
您正在使用 Circular ImageView 库。因此，您需要检查是否有任何属性可以在 ImageView 中设置图标。无论如何，这是实现所需行为的方法。您可以添加带有相机图标的图像，而不是设置背景颜色。
<com.almabay.almachat.circularImageView.CircularImageView
android:id="@+id/iv_camera"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="top|right"
android:layout_marginTop="@dimen/margin30"
android:background="@drawable/image_with_camera" />
Another approach you might try to get this behaviour is setting the camera image as a src attribute.
您可能尝试获得此行为的另一种方法是将相机图像设置为 src 属性。
<com.almabay.almachat.circularImageView.CircularImageView
android:id="@+id/iv_camera"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="top|right"
android:layout_marginTop="@dimen/margin30"
android:background="@drawable/color"
android:padding="5dp"
android:src="@drawable/image_camera" />

Logic is here to use frame layout
逻辑在这里使用框架布局
<FrameLayout
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="center"
android:layout_marginTop="10dp">
<xxx.xxxx.CircleImageView
android:id="@+id/profilePic"
android:layout_width="150dp"
android:layout_height="150dp"
android:src="@drawable/male"
android:layout_gravity="bottom|center_horizontal" />
<xxx.xxx.CircleImageView
android:id="@+id/iv_camera"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="@drawable/editfloat"
android:layout_gravity="top|right"
/>
</FrameLayout>
