刷新图像的媒体库影片 [英] Refresh MediaStore for Images & Videos

问题描述

我根据需要移动和删除了大量图像和视频，现在我正在使用以下介质扫描媒体

I moving and deleting lots of images and videos as per my requirement and now i am scan media by using

Intent scanFileIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
sendBroadcast(scanFileIntent);

一切正常，但有时会冻结屏幕，我认为MediaScanner中存在一些问题。

all working fine but sometime freeze the screen, i think some issue in MediaScanner.

我的第二个问题是如何扫描所有媒体存储介质而不是扫描perticuler文件。

And my second quetion is how to scan all media Store rether than scan perticuler File.

谢谢！！！ >

Thanks in Advance!!

推荐答案

您应尝试使用此解决方案删除并删除图像。

You should try this solution for amove and delete the image.

在deleteRecursive（fileOrDirectory）内部传递文件目录路径，即可从文件或目录中删除多个图像和单个图像。

public void deleteRecursive(File fileOrDirectory) {
    if (!fileOrDirectory.isDirectory()) return;
    File[] childFiles = fileOrDirectory.listFiles();
    if (childFiles == null) return;
    if (childFiles.length == 0) {
        fileOrDirectory.delete();
    } else {
        for (File childFile : childFiles) {
            deleteRecursive(childFile);
            DeleteAndScanFile(MainActivity.this, childFile.getPath(), childFile);
        }
    }


}

private void DeleteAndScanFile(final Context context, String path,
                               final File fi) {
    String fpath = path.substring(path.lastIndexOf("/") + 1);
    try {
        MediaScannerConnection.scanFile(context, new String[]{Environment
                        .getExternalStorageDirectory().toString()
                        + "/abc/"
                        + fpath.toString()}, null,
                new MediaScannerConnection.OnScanCompletedListener() {
                    public void onScanCompleted(String path, Uri uri) {
                        if (uri != null) {
                            context.getContentResolver().delete(uri, null,
                                    null);
                        }
                        fi.delete();
                    }
                });
    } catch (Exception e) {
        e.printStackTrace();
    }

}
