在这里插入图片描述

首先是layout里的代码，但这之前需要在build.gradle里加两行代码，主要是圆形图片和别的按钮啥的，你也可以改成自己的，不加圆形图片用系统原来的图片也是可以的。

下面的xml文件是弹出的小框的layout文件在这里插入图片描述

2.layout_bottom_dialog.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="wrap_content"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tv_album"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/shape_album"
            android:gravity="center"
            android:padding="15dp"
            android:text="相册"
            android:textSize="16sp"/>

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="#f5f5f5"/>

        <TextView
            android:id="@+id/tv_camera"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/shape_camera"
            android:gravity="center"
            android:padding="15dp"
            android:text="拍照"
            android:textSize="16sp"/>

        <TextView
            android:id="@+id/tv_cancel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:background="@drawable/shape_cancel"
            android:gravity="center"
            android:padding="15dp"
            android:text="取消"
            android:textSize="16sp"/>

    </LinearLayout>

</LinearLayout>

还有一个需要注意到的是因为需要用到摄像头和相册的图，需要在AndroidManifest.xml加一下下面的代码：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

AndroidManifest.xml里面里面:
在这里插入图片描述

 <provider
            android:authorities="com.example.cameraalbumtest.fileprovider"
            android:name="androidx.core.content.FileProvider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths"/>
 </provider>

layout 里建一个xml文件夹然后建一个文件，如下图
在这里插入图片描述
代码：

<?xml version="1.0" encoding="utf-8" ?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="my_images" path="" />
</paths>

3.fragment 里的代码：
