1权限 和 动态申请

2 app 属性添加

然后在 你的application 中加入 这个属性 :

android:requestLegacyExternalStorage="true"

3 mxl 设置

android:name="androidx.core.content.FileProvider"

android:authorities="com.base.baselib.fileprovider"

android:exported="false"

android:grantUriPermissions="true">

android:name="android.support.FILE_PROVIDER_PATHS"

android:resource="@xml/file_paths" />

在res 中添加 xml包和 file_paths.xml文件

name="external_files"

path="." />

4 代码配置

在你的 Application继承类中添加

private void initFileXml() {

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();

StrictMode.setVmPolicy(builder.build());

builder.detectFileUriExposure();

}

5 代码实现

/**

* 打开相机

*/

private void openPhotograph() {

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

// 创建文件工具类 设置相机图片路径(用时间戳)

mImagePath = FileUtils.getImageFilePath();

//检查文件是否存在

FileUtils.checkOrCreateDirectory(mImagePath);

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(mImagePath)));

mActivity.startActivityForResult(intent, Photograph_code);

}

/**

* 打开相册

*/

private void openAlbum() {

//打开系统的相册

if (mMaxSize == 0) {

Intent intent = new Intent(Intent.ACTION_PICK, null);

intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");

mActivity.startActivityForResult(intent, Album_code);

return;

}

//打开自定义的相册

AlbumActivity.gotoActivity(mActivity, AlbumList_code, mMaxSize);

}

public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {

if (mAlbumListener == null) return;

if (resultCode != RESULT_OK) return;

List list = new ArrayList<>();

if (requestCode == AlbumList_code && data != null) {

//多选图片

list = (List) data.getSerializableExtra(ImageList);

}

if (requestCode == Album_code && data != null) {

//单选图片 获图片的绝对地址

mImagePath = FileUtils.getImageAbsolutePath(mActivity, data.getData());

list.add(mImagePath);

}

if (requestCode == Photograph_code) {

//拍照图片

list.add(mImagePath);

}

mAlbumListener.onListener(list);

}
