CircleImageView:一個圓形的ImageView,可以繪製邊框寬度和顏色

官方說明:

Gradle

dependencies {
    ...
    implementation 'de.hdodenhof:circleimageview:2.2.0'
}

Usage

<de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profile_image"
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:src="@drawable/profile"
    app:civ_border_width="2dp"
    app:civ_border_color="#FF000000"/>
 

Limitations

• The ScaleType is always CENTER_CROP and you'll get an exception if you try to change it. This is (currently) by design as it's perfectly fine for profile images.
• Enabling adjustViewBounds is not supported as this requires an unsupported ScaleType
• If you use an image loading library like Picasso or Glide, you need to disable their fade animations to avoid messed up images. For Picasso use the noFade()
   option, for Glide use dontAnimate(). If you want to keep the fadeIn animation, you have to fetch the image into a Target and apply a custom animation yourself when receiving the Bitmap.
• Using a TransitionDrawable with CircleImageView doesn't work properly and leads to messed up images.

FAQ

How can I use a VectorDrawable with CircleImageView?

Short answer: you shouldn't. Using a VectorDrawable with CircleImageView is very inefficient. You should modify your vectors to be in a circular shape and use them with a regular ImageView instead.

Why doesn't CircleImageView extend AppCompatImageView?

Extending AppCompatImageView would require adding a runtime dependency for the support library without any real benefit.

How can I add a selector (e.g. ripple effect) bound to a circle?

There's currently no direct support for a circle bound selector but you can follow these steps to implement it yourself.

How can I add a gap between image and border?

Adding a gap is also not support directly but there's a workaround.
