先上个图吧 .点击头像弹出下面对话框,然后直接上代码.

头像是自定义控件实现的圆形头像,当然就目前而言 想要实现 圆形头像的资料太多了,随便找个就行

<com.kuibu.jucai.widget.CircleImageView
                style="@style/UserFaceImageStyle"
                app:border_color="@color/white"
                app:border_width="2dip"
                android:id="@+id/header_img"
                 />

对应样式:

<style name="UserFaceImageStyle">
            <item name="android:layout_width">60.0dip</item>
            <item name="android:layout_height">60.0dip</item>
            <item name="android:padding">1.0dip</item>
            <item name="android:clickable">true</item>
            <item name="android:contentDescription">face</item>
            <item name="android:src">@mipmap/widget_dface</item>
            <item name="android:layout_alignParentRight">true</item>
            <item name="android:layout_centerVertical">true</item>
        </style>

点击头像后的代码如下: 这里传递的是base64字符串.  当然也可以不转成base64,直接传递拍照后的 地址也是可以的.根据接口来定

另外本类需实现implements EasyPermissions.PermissionCallbacks 该接口
