H5页面调用安卓相机拍照，然后在H5页面显示：
1、H5调用相机的回调：
binding.fragmentWebWebview.setWebChromeClient(new WebChromeClient() {@Overridepublic boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {openCamera();filePathCallbacks = filePathCallback;return true;}});2、开始拍照，图片存储到手机app的缓存目录中，你可以存到sdcard中
protected void openCamera(String currentComptUuid) {Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);File appDir = new File(parentPath + "/" + currentComptUuid);if (!appDir.exists()) {appDir.mkdir();}String fileName = System.currentTimeMillis() + ".jpg";File file = new File(appDir, fileName);originalPicPath = file.getPath();mCameraUri = FileProvider.getUriForFile(this, getPackageName() + ".fileprovider", new File(originalPicPath));intent.putExtra(MediaStore.EXTRA_OUTPUT, mCameraUri);startActivityForResult(intent, 0x22);}3、拍完照片，处理照片的回调信息，并采用鲁班缩框架压缩图片
@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode != -1) { //如果取消拍照filePathCallbacks.onReceiveValue(null);filePathCallbacks = null;return;}switch (requestCode) {case 0x22://图片压缩 不然会很大File appDir = new File(originalPicPath); //原图片地址if (!appDir.exists()) {appDir.mkdir();}refrshAlbum(originalPicPath); //同步更新手机相册imageZips(this, originalPicPath, appDir.getParent());break;}}public void refrshAlbum(String path) {try {File imageFile = new File(path);MediaStore.Images.Media.insertImage(this.getContentResolver(),path, imageFile.getName(), "description");} catch (Exception e) {LogUtils.log("refrshAlbum:" + e);}}protected String originalPicPath; //原始图片地址protected void imageZips(Context context, String photos, String targetPath) {//图片压缩Luban.with(this).load(photos).ignoreBy(600).setTargetDir(targetPath) //压缩后文件目录， 如果希望替换原图就不要这行.filter(path -> !(TextUtils.isEmpty(path) || path.toLowerCase().endsWith(".gif"))).setCompressListener(new OnCompressListener() {@Overridepublic void onStart() {Log.i("get_path", "开始压缩");}@Overridepublic void onSuccess(File file) {Log.i("get_path", "文件名：" + file.getName() + " 压缩成功 路径：" + file);Uri tempUri = Uri.fromFile(file);filePathCallbacks.onReceiveValue(new Uri[]{tempUri}); //将照片给H5filePathCallbacks = null;File orinalFile = new File(originalPicPath); //删除原图片if (orinalFile.exists()) {orinalFile.delete();}// 这个不是在主线程，跟新ui ，切换到主线程}@Overridepublic void onError(Throwable e) {LogUtils.log("压缩失败:" + e);}}).launch();}
