Android-如何使用隐式意图在图库中打开特定文件夹？

Question

We are building a camera app that saves photos in a specific folder in the gallery. And we have to open the folder of our app in the gallery using an intent. We are using this code however it shows all folders.

View.OnClickListener goToGallery = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setAction(android.content.Intent.ACTION_VIEW);
        intent.setType("image/*");
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
};

Answer 1

Try this code. It will retrieve view pictures under storage/emulated/0/Pictures/MyAppPics You can change the file path according to your directory path.

File sdDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File f = new File(sdDir, "MyAppPics");

Intent i = new Intent();
i.setAction(Intent.ACTION_VIEW);
i.setDataAndType(Uri.withAppendedPath(Uri.fromFile(f), "/MyAppPics"), "image/*");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);

Answer 2

To open gallery I use this intent.

public static final int RESULT_GALLERY = 0;

Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(galleryIntent , RESULT_GALLERY );
