Android之自定义相册文件选择器

一、自定义FilePicker类

package com.custom.jfrb.util; //自己的包名位置import android.app.Activity;
import androidx.fragment.app.Fragment;import com.luck.picture.lib.PictureSelector;
import com.luck.picture.lib.config.PictureConfig;
import com.luck.picture.lib.config.PictureMimeType;public class FilePicker {public static final int FROM_ALBUM = 20001;public static final int TAKE_PICTURE = 20005;int selectionMode = PictureConfig.MULTIPLE;int mimeType = PictureMimeType.ofAll();int maxChoose = 20;boolean previewImage = true;boolean isCrop = false;boolean isCircleCrop = true;public boolean isShowCamera = false;int cropWidth;int cropHeight;Activity activity;Fragment fragment;public FilePicker(Activity activity) {this.activity = activity;}public FilePicker(Fragment fragment) {this.fragment = fragment;}public void start() {PictureSelector pictureSelector;if (activity != null) {pictureSelector = PictureSelector.create(activity);} else {pictureSelector = PictureSelector.create(fragment);}pictureSelector.openGallery(mimeType)//全部.PictureMimeType.ofAll()、图片.ofImage()、视频.ofVideo().loadImageEngine(GlideEngine.createGlideEngine()).maxSelectNum(maxChoose)// 最大图片选择数量 int.minSelectNum(1)// 最小选择数量 int.imageSpanCount(4)// 每行显示个数 int.selectionMode(selectionMode)// 多选 or 单选 PictureConfig.MULTIPLE or PictureConfig.SINGLE.previewImage(previewImage)// 是否可预览图片 true or false.previewVideo(false)// 是否可预览视频 true or false.enablePreviewAudio(false) // 是否可播放音频 true or false.isCamera(isShowCamera)// 是否显示拍照按钮 true or false.isZoomAnim(false)// 图片列表点击 缩放效果 默认true.sizeMultiplier(0.5f)// glide 加载图片大小 0~1之间 如设置 .glideOverride()无效.enableCrop(isCrop)// 是否裁剪 true or false.withAspectRatio(cropWidth, cropHeight).circleDimmedLayer(isCircleCrop).scaleEnabled(true).rotateEnabled(false) // 裁剪是否可旋转图片press(true)// 是否压缩 true or false.cropCompressQuality(80).isGif(false)// 是否显示gif图片 true or false.openClickSound(false)// 是否开启点击声音 true or false.forResult(FROM_ALBUM);//结果回调onActivityResult code}public void start(int requestId) {PictureSelector pictureSelector;if (activity != null) {pictureSelector = PictureSelector.create(activity);} else {pictureSelector = PictureSelector.create(fragment);}pictureSelector.openGallery(mimeType)//全部.PictureMimeType.ofAll()、图片.ofImage()、视频.ofVideo().maxSelectNum(20)// 最大图片选择数量 int.minSelectNum(1)// 最小选择数量 int.imageSpanCount(4)// 每行显示个数 int.selectionMode(selectionMode)// 多选 or 单选 PictureConfig.MULTIPLE or PictureConfig.SINGLE.previewImage(false)// 是否可预览图片 true or false.previewVideo(false)// 是否可预览视频 true or false.enablePreviewAudio(false) // 是否可播放音频 true or false.isCamera(false)// 是否显示拍照按钮 true or false.isZoomAnim(false)// 图片列表点击 缩放效果 默认true.sizeMultiplier(0.5f)// glide 加载图片大小 0~1之间 如设置 .glideOverride()无效.enableCrop(isCrop)// 是否裁剪 true or false.circleDimmedLayer(true).hideBottomControls(true).rotateEnabled(true) // 裁剪是否可旋转图片press(false)// 是否压缩 true or false.hideBottomControls(true)// 是否显示uCrop工具栏，默认不显示 true or false.isGif(false)// 是否显示gif图片 true or false.openClickSound(false)// 是否开启点击声音 true or false.forResult(requestId);//结果回调onActivityResult code}// 开启拍照public void startPicture() {PictureSelector pictureSelector;if (activity != null) {pictureSelector = PictureSelector.create(activity);} else {pictureSelector = PictureSelector.create(fragment);}pictureSelector.openCamera(PictureMimeType.ofImage()).enableCrop(isCrop)// 是否裁剪 true or false.circleDimmedLayer(isCrop).rotateEnabled(true) // 裁剪是否可旋转图片.forResult(TAKE_PICTURE);}public void setSelectionMode(int selectionMode) {this.selectionMode = selectionMode;}public void setMimeType(int mimeType) {this.mimeType = mimeType;}public void setMaxChoose(int maxChoose) {this.maxChoose = maxChoose;}public void setCrop(boolean isCrop) {this.isCrop = isCrop;}public void setCircleCrop(boolean isCircleCrop) {this.isCircleCrop = isCircleCrop;}public void setCropWidth(int cropWidth) {this.cropWidth = cropWidth;}public void setCropHeight(int cropHeight) {this.cropHeight = cropHeight;}public void setPreviewImage(boolean previewImage) {this.previewImage = previewImage;}
}

二、场景使用1（选择单个图片作为头像/封面等）

1、给某个控件添加监听，调用相册文件选择器

//选择相册文件后显示在ivUpload控件上
ImageView ivUpload = findViewById(R.id.img_upload)

FilePicker filePicker = new FilePicker(this);
filePicker.setMimeType(PictureMimeType.ofImage()); //选择类型是图片，只调出相册中所有图片文件
filePicker.setMaxChoose(1); //单次最多选择文件数量为1，可变
filePicker.setCrop(true);
filePicker.isShowCamera = true; //设置打开后有开始拍照项
filePicker.setCircleCrop(false);
filePicker.setCropWidth(ivUpload.getWidth()); 
filePicker.setCropHeight(ivUpload.getHeight());
filePicker.start();

2、选择图片后回调

    @SuppressLint("MissingSuperCall")@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == FROM_ALBUM) {if (resultCode == Activity.RESULT_OK) {String path;List<LocalMedia> selectList = PictureSelector.obtainMultipleResult(data);if (selectList != null && !selectList.isEmpty()) {if (selectList.get(0).isCut()) {path = selectList.get(0).getCutPath();} else if (selectList.get(0).isCompressed()) {path = selectList.get(0).getCompressPath();} else {path = selectList.get(0).getPath();}   //加载选择的图片到控件中Glide.with(context).load(path).apply(options).into(ivUpload);}}}}

三、场景使用2（选择多个视频 /（图片）展示到页面上）

1、给某个控件添加监听，调用相册文件选择器

FilePicker filePicker = new FilePicker(this);
filePicker.setMimeType(PictureMimeType.ofVideo()); //设置选择类型为视频
filePicker.setMaxChoose(30); //设置单次选择最大数量为30个
filePicker.setSelectionMode(PictureConfig.MULTIPLE);
filePicker.start();

2、选择视频回调

    @SuppressLint("MissingSuperCall")@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {switch (requestCode) {case FROM_ALBUM://选择相册文件后回调if (resultCode == Activity.RESULT_OK) {List<LocalMedia> selectList = PictureSelector.obtainMultipleResult(data);if (selectList != null && selectList.size() > 0){int testCount = 0;String productPath = null;for (LocalMedia localMedia : selectList) {String path = localMedia.getPath();String TAG = "mylog_upload_file";Log.i(TAG, "压缩::" + localMedia.getCompressPath());Log.i(TAG, "原图::" + localMedia.getPath());Log.i(TAG, "裁剪::" + localMedia.getCutPath());Log.i(TAG, "是否开启原图::" + localMedia.isOriginal());Log.i(TAG, "原图路径::" + localMedia.getOriginalPath());Log.i(TAG, "Android Q 特有Path::" + localMedia.getAndroidQToPath());if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.Q) {// 这个设备的 Android 版本大于 Android Q// 在这里执行你的代码path = localMedia.getAndroidQToPath();} else if(localMedia.isOriginal()){Log.i(TAG, "原图路径::" + localMedia.getOriginalPath());path = localMedia.getOriginalPath();}else{path = localMedia.getCompressPath();}Log.d("mylog_upload_file","选择文件的路径是："+ path);FileInfoStatus fileInfo = null;if(PublicUtils.isVideo(path)){fileInfo = getLocalFile(path);  //根据路径信息创建自己的JavaBean对象进行信息的展示，也可以创建List对象去存储，进而可以展示到recyclerview或其他布局中}else{RnToast.showToastLong(this,"只支持Mp3文件!");}}}}break;default:break;}}

FileInfoStatus为自己定义的文件信息类

package com.custom.jfrb.ui.fileTransfer.FileUploadUtils.bean;import android.graphics.BitmapFactory;import com.custom.jfrb.ui.fileTransfer.FileUploadUtils.base.DataTypeEnum;
import com.custom.jfrb.ui.fileTransfer.FileUploadUtils.db.DBHelper;
import com.custom.jfrb.ui.first.bean.MaterialDTO;
import com.custom.jfrb.util.PublicUtils;
import com.qukan.qkrecordupload.ConfigureManagerUtil;
import com.qukan.qkrecordupload.QkApplication;import java.io.File;
import java.io.Serializable;import static com.custom.jfrb.ui.fileTransfer.FileUploadUtils.base.DataTypeEnum.DISK;public class FileInfoStatus extends com.qukan.qkrecordupload.file.FileInfoStatus implements Serializable {public static final double GB = 1024.0 * 1024 * 1024;public static final double MB = 1024.0 * 1024;public static final double KB = 1024.0;protected String fileName;protected String timeLength;protected String filePath;protected String timeDate;protected String fileDisplayName;// 文件的大小protected String fileLength;public String getTimeLength(){return timeLength;}public long getFileTrueSize() {File temp = new File(filePath);if (!temp.isFile()){return 0;}// 获取文件的大小return temp.length();}public String getFileLength(){if("0".endsWith(fileLength)||"0B".endsWith(fileLength)){File temp = new File(filePath);long fileSize = temp.length();if (fileSize > GB){fileLength =  String.format("%.2fGB", fileSize / GB);}else if (fileSize > MB){fileLength = String.format("%.2fMB", fileSize / MB);}else if (fileSize > KB){fileLength = String.format("%.2fKB", fileSize / KB);}else{fileLength = String.format("%dB", fileSize);}if(!("0".endsWith(fileLength)||"0B".endsWith(fileLength))){DBHelper.instance().update(this);}}return fileLength;}public int getWidth() {BitmapFactory.Options options = new BitmapFactory.Options();options.inJustDecodeBounds = true;BitmapFactory.decodeFile(filePath, options); // 此时返回的bitmap为nullreturn  options.outWidth;}public int getHeight() {BitmapFactory.Options options = new BitmapFactory.Options();options.inJustDecodeBounds = true;BitmapFactory.decodeFile(filePath, options); // 此时返回的bitmap为nullreturn  options.outHeight;}/*文件类型：视频8 音频9 图10*/private int intFileType = -1;public void setIntFileType(int intFileType) {this.intFileType = intFileType;}//......省略了一些getter和setter方法}

拿到路径后创建自己的对象

    public static FileInfoStatus getLocalFile(String filePath) {File temp = new File(filePath);String pathFileName = temp.getName();L.d("pathFileName=%s", pathFileName);String[] arr = pathFileName.split("\\.");String pathHouzhui = arr[arr.length - 1]; //获取文件后缀if (!temp.isFile()) {return null;}FileInfoStatus fileInfo = new FileInfoStatus();fileInfo.setFilePath(temp.getPath());// 获取文件的大小long fileSize = temp.length();if (fileSize > GB) {fileInfo.setFileLength(String.format("%.2fGB", fileSize / GB));} else if (fileSize > MB) {fileInfo.setFileLength(String.format("%.2fMB", fileSize / MB));} else if (fileSize > KB) {fileInfo.setFileLength(String.format("%.2fKB", fileSize / KB));} else {fileInfo.setFileLength(String.format("%dB", fileSize));}// 设置日期和时长String timeDate = formatter.format(new Date(System.currentTimeMillis()));fileInfo.setTimeDate(timeDate);MediaMetadataRetriever mmr = new MediaMetadataRetriever();mmr.setDataSource(filePath);String duration = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);fileInfo.setTimeLength(PublicUtils.msToHms(Long.parseLong(duration)));String newFileName = getTimeAndRandom();String uploadFilename = newFileName + "_upload0." + pathHouzhui;fileInfo.setFileDisplayName(pathFileName);fileInfo.setFileName(newFileName + "_" + 0 + "." + pathHouzhui);file.setIntFileType(8);   //设置文件类型是视频8return fileInfo;}

//几个判断文件类型的方法

	//是否是视频文件public static boolean isVideo(String path) {if (path.endsWith("mp4") || path.endsWith("MP4")) {return true;} else {return false;}}//是否是图片文件public static boolean isImage(String path) {if (path.endsWith("jpg") || path.endsWith("JPG") || path.endsWith("png") || path.endsWith("PNG")|| path.endsWith("jpeg")|| path.endsWith("JPEG")) {return true;} else {return false;}}//是否是音频文件public static boolean isAudio(String path) {if (path.endsWith("mp3") || path.endsWith("MP3") ) {return true;} else {return false;}}

视频文件转换方法 类似 00:00:00

public static String msToHms(long milliSecondTime) {int hour = (int) milliSecondTime / (60 * 60 * 1000);int minute = (int) (milliSecondTime - hour * 60 * 60 * 1000) / (60 * 1000);int seconds = (int) (milliSecondTime - hour * 60 * 60 * 1000 - minute * 60 * 1000) / 1000;if (seconds >= 60) {seconds = seconds % 60;minute += seconds / 60;}if (minute >= 60) {minute = minute % 60;hour += minute / 60;}String sh = "";String sm = "";String ss = "";if (hour < 10) {sh = "0" + String.valueOf(hour);} else {sh = String.valueOf(hour);}if (minute < 10) {sm = "0" + String.valueOf(minute);} else {sm = String.valueOf(minute);}if (seconds < 10) {ss = "0" + String.valueOf(seconds);} else {ss = String.valueOf(seconds);}return sh + ":" + sm + ":" + ss;}

三、完成、Nice！
