如何在Android中以编程方式向画廊添加图像或以编程方式刷新画廊 [英] How to add images to gallery programmatically in android or refresh gallery programmatically

问题描述

我正在将某些图像从服务器下载到文件夹中的sd卡中.图像已成功存储在sd卡中.但是问题在于，图像同时没有在图库中显示.如果我重新启动设备，则它将显示在图库中.

I am downloading some of the images from server to sd card in a folder. Images are storing in sd card successfully. But the problem is that at the same time images are not showing in gallery. If i restart the device then it will be showing in gallery.

如何以编程方式刷新图库，以便每当我从服务器获取图像时都可以同时看到图像?

How can I refresh the gallery programmatically so images can be visible simultaneously whenever I fetch images from server?

推荐答案

我明白了，下面的代码将扫描您的图像文件，并将其同时提供给图库:

I got it, below code will scan your image file and make it available simultaneously to gallery also:

MediaScannerConnection.scanFile(context,
            new String[] { file.toString() }, null,
            new MediaScannerConnection.OnScanCompletedListener() {
        public void onScanCompleted(String path, Uri uri) {
            Log.i("ExternalStorage", "Scanned " + path + ":");
            Log.i("ExternalStorage", "-> uri=" + uri);
        }
    });
