Android - get file path of gallery image สอบถามเรื่องการ get ชื่อรูปจาก gallery

// To open up a gallery browser
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),1);

// To handle when an image is selected from the browser, add the following to your Activity
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) { 

        if (resultCode == RESULT_OK) {

                if (requestCode == 1) {

                        // currImageURI is the global variable I'm using to hold the content:// URI of the image
                        currImageURI = data.getData();
                }
        }
}

// And to convert the image URI to the direct file system path of the image file
public String getRealPathFromURI(Uri contentUri) {

        // can post image
        String [] proj={MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery( contentUri,
                        proj, // Which columns to return
                        null,       // WHERE clause; which rows to return (all rows)
                        null,       // WHERE clause selection arguments (none)
                        null); // Order-by clause (ascending by name)
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        return cursor.getString(column_index);
}
