要在 Android 13 上实现图片选择、显示并添加裁剪功能，我们可以使用第三方裁剪库如 UCrop。以下是完整实现方案：
1. 添加依赖
在 build.gradle (Module) 中添加：

dependencies {// 基础依赖implementation 'androidx.activity:activity-ktx:1.7.0'implementation 'androidx.fragment:fragment-ktx:1.5.7'implementation 'com.github.bumptech.glide:glide:4.14.2'annotationProcessor 'com.github.bumptech.glide:compiler:4.14.2'// 图片裁剪库implementation 'com.github.yalantis:ucrop:2.2.8'// 可选，用于处理Android 13+照片选择器implementation 'androidx.activity:activity-ktx:1.7.0'
}

}

activity_image_picker_crop.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:padding="16dp"android:gravity="center"><ImageViewandroid:id="@+id/imageView"android:layout_width="300dp"android:layout_height="300dp"android:scaleType="centerCrop"android:background="#f0f0f0"android:contentDescription="Cropped image" /><Buttonandroid:id="@+id/selectButton"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="24dp"android:text="选择并裁剪图片" /></LinearLayout>

AndroidManifest.xml配置：

  <!--相册--><uses-permission android:name="android.permission.READ_MEDIA_IMAGES" /><!-- 对于 Android 13 以下版本的回退权限 --><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"android:maxSdkVersion="32" />

在 AndroidManifest.xml 中添加 UCrop 所需的配置

<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="your.package.name"><application><!-- 其他你的Activity声明 --><!-- UCrop 所需的Activity声明 --><activityandroid:name="com.yalantis.ucrop.UCropActivity"android:screenOrientation="portrait"android:theme="@style/Theme.AppCompat.Light.NoActionBar"/><!-- 其他配置 --></application></manifest>
