Question

我正在尝试拍照或从图库中选择它，压缩它并将其保存在手机上的单独文件夹中。照片被拍摄并放入$scope.test2 = function (name) { var res = 'http://example.com?from=' + name; var range = document.createRange(); range.selectNode(res); // here getting error window.getSelection().addRange(range); try { var successful = document.execCommand('copy'); var msg = successful ? 'successful' : 'unsuccessful'; console.log('Copy email command was ' + msg); } catch (err) { console.log('Oops, unable to copy'); } window.getSelection().removeAllRanges(); }但我无法在imageview找到它，即使在几分钟之后也是如此。可能是什么问题？

gallery

String mPhotoLocation;

压缩图片

private void takePhoto() {
    Intent takePhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File photoFile = null;
    try {
        photoFile = photoPath();
    } catch (IOException e) {
        e.printStackTrace();
    }
    Uri photoURI = FileProvider.getUriForFile(getContext(),
            getContext().getApplicationContext().getPackageName() + ".provider",
            photoFile);
    takePhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
    startActivityForResult(takePhoto, REQUEST_CAMERA);
}

保存图像后调用此方法

  public static void notifySystemGallery(Context context, File file) {
    if (file == null || !file.exists()) {
        Log.e(TAG, "notifySystemGallery: the file do not exist.");
        return;
    }

    try {
        MediaStore.Images.Media.insertImage(context.getContentResolver(), file.getAbsolutePath(),
                file.getName(), null);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));
}

照片永远不会在新文件夹中的图库中显示
