Introduction and usage guide for CircleImageView frameworks

The CircleImageView framework is an open source library for displaying circular pictures in Android applications.It provides a custom IMAGEVIEW class called CircleImageView, which can easily cut the normal rectangular pictures into circles and display it in the application. It is very simple to use the CircleImageView framework.First, you need to add the following dependencies to the project built.gradle file: implementation 'de.hdodenhof:circleimageview:3.1.0' Then, replace the ImageView in the layout file to the CircleImageView: <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/circleImageView" android:layout_width="96dp" android:layout_height="96dp" android:src="@drawable/profile_image" /> In the Java code, you can use the CircleImageView as follows: CircleImageView circleImageView = findViewById(R.id.circleImageView); circleImageView.setImageResource(R.drawable.profile_image); CircleImageView also provides some optional XML attributes to customize the boundary style and color of round pictures.Here are some commonly used attributes: -` APP: CIV_Border_width`: Set the width of the boundary. -` APP: CIV_Border_Color`: Set the color of the boundary. -` APP: CIV_Border_Overlay`: If it is set to TRUE, the boundary will be covered above the picture. Create a custom attribute example: Add the following code to the res/value/attrs.xml file: <resources> <declare-styleable name="CircleImageView"> <attr name="civ_border_width" format="dimension" /> <attr name="civ_border_color" format="color" /> <attr name="civ_border_overlay" format="boolean" /> </declare-styleable> </resources> Then, you can use these custom attributes in the layout file: <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/circleImageView" android:layout_width="96dp" android:layout_height="96dp" android:src="@drawable/profile_image" app:civ_border_width="2dp" app:civ_border_color="@color/border_color" app:civ_border_overlay="true" /> CircleImageView is a simple and powerful library that allows developers to easily display circular pictures in Android applications.Through simple configuration, you can add border styles to the picture and achieve more personalized effects.
