一.第三方RoundedImageView

1.在Android Studio中，可进入模块设置中添加库依赖。 进入Module结构设置添加库依赖 ，输入RoundedImageView然后搜索添加

2.在Moudle的build.gradle中添加如下代码，添加完之后在Build中进行下Make Module操作（编译下Module），使自己添加的依赖生效

implementation ‘com.makeramen:roundedimageview:2.3.0’

3.添加相关属性：

控件属性： 
    riv_border_width： 边框宽度 
    riv_border_color： 边框颜色 
    riv_oval： 是否圆形 
    riv_corner_radius： 圆角弧度 
    riv_corner_radius_top_left：左上角弧度 
    riv_corner_radius_top_right： 右上角弧度 
    riv_corner_radius_bottom_left：左下角弧度 
    riv_corner_radius_bottom_right：右下角弧度

4.示例布局：

<com.makeramen.roundedimageview.RoundedImageView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"

              app:riv_border_width="2dp"
              app:riv_oval="true" />

二.自定义RoundImageView

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NoZW5nZ2FvZmVp_size_16_color_FFFFFF_t_70][]

1.布局：

<com.iruiyou.pet.utils.RoundImageView
    		android:id="@+id/headIv"
            android:layout_width="125dp"
            android:layout_height="125dp"
            android:layout_marginTop="92dp"
            android:src="@drawable/head_home"
            loonggg:border_incolor="#000fff"
            loonggg:border_outcolor="#fff000"
            loonggg:border_width="10dp"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent"/>

2.自定义类：

    import android.content.res.TypedArray;
    import android.graphics.Bitmap;
    import android.graphics.Canvas;
    import android.graphics.Paint;
    import android.graphics.PorterDuff;
    import android.graphics.PorterDuffXfermode;
    import android.graphics.Rect;
    import android.graphics.drawable.BitmapDrawable;
    import android.graphics.drawable.Drawable;
    import android.graphics.drawable.NinePatchDrawable;
    import android.util.AttributeSet;
    import android.widget.ImageView;
    import com.iruiyou.pet.R;
     
    /**

            a.recycle();
        }
     
        // 具体解释：比如我自定义一个控件，怎么实现呢，以RoundImageView为例，首先是继承ImageView,然后实现其构造函数，在构造函数中，获取attr中的属性值（再次解释：这里获取的具体的这个属性的值是怎么来的呢？比如颜色和宽度，这个在attr.xml中定义了相关的名字，而在使用RoundImageView的xml布局文件中，我们会设置其值，这里需要用的值，就是从那里设置的），并设置在本控件中，然后继承onDraw方法，画出自己想要的图形或者形状即可
        /**
         * 这个是继承的父类的onDraw方法
         *
         * onDraw和下面的方法不用管，基本和学习自定义没关系，就是实现怎么画圆的，你可以改变下面代码试着画三角形头像，哈哈

3.res--values--attrs.xml文件

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <declare-styleable name="round_image_view">
            <attr name="border_width" format="dimension" />
            <attr name="border_incolor" format="color" />
            <attr name="border_outcolor" format="color"></attr>
        </declare-styleable>
    </resources>

三.第三方NiceImageView

1.效果图如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NoZW5nZ2FvZmVp_size_16_color_FFFFFF_t_70 1][]

2.特点：

基于AppCompatImageView扩展

支持圆角、圆形显示

可绘制边框，圆形时可绘制内外两层边框

支持边框不覆盖图片

可绘制遮罩

3.基本用法：

** **1. 添加JitPack仓库 在项目根目录下的 `build.gradle` 中添加仓库:

allprojects {
        repositories {
            ...
            maven { url "https://jitpack.io" }
        }
    }

2. 添加项目依赖

dependencies {
        implementation 'com.github.SheHuan:NiceImageView:1.0.5'
    }

3. 在布局文件中添加CornerLabelView

<com.shehuan.niv.NiceImageView
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_marginTop="10dp"
        android:src="@drawable/cat"
        app:border_color="#FF7F24"
        app:border_width="4dp"
        app:is_circle="true" />

4.支持的属性、方法

<table> 
 <thead> 
  <tr> 
   <th>属性名</th> 
   <th>含义</th> 
   <th>默认值</th> 
   <th>对应方法</th> 
  </tr>

5.其它：

如果你需要实现类似钉钉的圆形组合头像，例如：

可以先生成对应的Bitmap，并用圆形的 NiceImageView 显示即可。如何生成组合Bitmap可以参考这里：[CombineBitmap][]

四.如果你的项目中只有圆形的图片而不需要设置圆角图片的话，可以试试下面的第三方：
