1.要用普通的图片的话就设置成简单的ImageView
圆形图片的话就先导入一个依赖 ： implementation 'de.hdodenhof:circleimageview:2.1.0'
示例为圆形图片：
一：main布局：
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/dage"
tools:context=".MainActivity">
android:layout_gravity="center"
android:id="@+id/imageID"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
android:text="点一下，给你惊喜"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/but"/>
PopupWoeder布局：
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
android:id="@+id/btn_02"
android:layout_height="wrap_content"
android:text="拍照"
android:layout_width="match_parent" />
android:id="@+id/btn_01"
android:layout_height="wrap_content"
android:text="相册"
android:layout_width="match_parent" />
android:id="@+id/btn_03"
android:layout_height="wrap_content"
android:text="取消"
android:layout_width="match_parent" />
