android用户头像选择(相册,相机拍照)进行裁剪显示

说明:新建项目把如下代码直接负责到自己的项目中运行
第一步: 使用的是一个第三方开源框架 takephoto_library

在build.gradle中添加
     implementation 'com.jph.takephoto:takephoto_library:4.0.3'
     implementation 'com.android.support:design:27.1.0'

第二步:献上完整代码复制就可以使用

如果需要显示圆形的头像框或其他形状的可以使用 Roundedimageview
```
添加  implementation 'com.makeramen:roundedimageview:2.3.0'
```

4.显示头像的布局文件如下:

           这个是圆形的
            <com.makeramen.roundedimageview.RoundedImageView
             xmlns:app="http://schemas.android.com/apk/res-auto"
               android:id="@+id/iv_avatar"
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:scaleType="centerCrop"
                android:src="@mipmap/head_portrait"
                app:riv_border_color="#333333"
                app:riv_border_width="2dip"
                app:riv_mutate_background="true"
                app:riv_oval="true"
                app:riv_tile_mode="repeat"
                app:riv_corner_radius="30dip"
                android:layout_centerInParent="true"
                />

备注说明,如果是7.0及以上版本的手机,调用系统照相机时需要做如下操作

1,AndroidManifest.xml文件里还需要加入这段：
	    	<provider
	                android:name="android.support.v4.content.FileProvider"
	                android:authorities="${applicationId}.fileprovider"
	                android:exported="false"
	                android:grantUriPermissions="true">
	                <meta-data
	                 android:name="android.support.FILE_PROVIDER_PATHS"
	                 android:resource="@xml/file_paths"/>
	     </provider>
	     
2,在res目录下创建xml文件夹,在xml文件夹中新建file_path.xml文件,代码如下:

		<?xml version="1.0" encoding="utf-8"?>
			<resources>
			    <paths>
			        <!--name 是起的别名(随便起)   path是要共享的文件夹 -->
			        <external-path
			            name="files_root"
			            path="Android/data/com.ele.lookover/" />
			        <external-path
			            name="/storage/emulated/0/"
			            path="." />
			    </paths>
			</resources>
