I have a camera app which save image to separate folder inside the gallery. Path to my folder is /storage/emulated/0/Pictures/CameraExample/

当我单击按钮时，我需要打开保存图像的文件夹.我已经使用了所有可用的解决方案.

这就是我阅读路径的方式.让我知道我是否错了.

This how I'm reading the path. Let me know if i'm wrong.

String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getAbsolutePath();
        Log.d("HelperUtils . getFilePaths", "setting the path " + path);
        String targetPath = path +"/CameraExample/";

如何启动新的Intent并打开文件?

How to start a new Intent and open the files?

推荐答案

您可以像这样列出目录中存在的所有文件

You can list all files which exist in your directory like this

File[] listFile;
File file = new File(android.os.Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "CameraExample");
if (file.isDirectory()) 
        listFile = file.listFiles();

然后，您可以使用GridView或根据需要显示这些图像.

Then you can display those images using GridView or however you want.

使用意图打开文件夹

To open your folder using intent

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath()
+ "/CameraExample/");
intent.setDataAndType(uri, "*/*");
startActivity(Intent.createChooser(intent, "Open folder"));
