Question

我实现了一个捕获图像并将其保存到我的自定义文件夹的应用程序。一切都很好，但问题是，当我捕捉图像时，我的画廊不会同步。这意味着画廊不会显示新的捕捉图像。因为我需要重新启动手机。

这是我的图像捕捉代码....

if (requestCode == 0 && resultCode == RESULT_OK) {
        String[] projection = {MediaStore.Images.ImageColumns.SIZE,
                MediaStore.Images.ImageColumns.DISPLAY_NAME,
                MediaStore.Images.ImageColumns.DATA,
                BaseColumns._ID,
                MediaStore.Images.ImageColumns.DATE_ADDED};
        final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
        final String selection = MediaStore.Images.Media.DATE_TAKEN + " > " + time;
        Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        CursorLoader loader = new CursorLoader(this, u,
                projection, selection, null, imageOrderBy);
        Cursor cursor = loader.loadInBackground();
        if (null != cursor && cursor.moveToFirst()) {
            ContentResolver cr = this.getContentResolver();
            cr.delete(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    BaseColumns._ID + "=" + cursor.getString(3), null);
        }
        //showing image in image view
        cameraPicture = output.getPath();
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 4;
        Bitmap bitmap = BitmapFactory.decodeFile(cameraPicture, options);
        binding.imageView.setImageBitmap(bitmap);
        binding.imageView.setVisibility(View.VISIBLE);
    }

所以当我捕获图像时，如何同步我的Android厨房？这样我就可以立即从厨房查看这张图片。

保存文件后需要通知系统

 private void scanFile(String path) {

    MediaScannerConnection.scanFile(MainActivity.this,
            new String[] { path }, null,
            new MediaScannerConnection.OnScanCompletedListener() {

                public void onScanCompleted(String path, Uri uri) {
                    Log.i("TAG", "Finished scanning " + path);
                }
            });
}
