I'm trying to make an app where user selects an Image from gallery and can rename it to desired name,
The code to get the Image from gallery is

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
 photoPickerIntent.setType("image/*");
 startActivityForResult(photoPickerIntent, RESULT_LOAD_IMG);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 super.onActivityResult(requestCode, resultCode, data);

 if (resultCode == RESULT_OK)
 try 
 upload.setVisibility(View.INVISIBLE);
 Image.setVisibility(View.VISIBLE);
 final Uri imageUri = data.getData();
 final InputStream imageStream = getContentResolver().openInputStream(imageUri);
 final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);

 Image.setImageBitmap(selectedImage);
 Log.i("FileName is", fileName);
 catch (FileNotFoundException e)
 e.printStackTrace();
 Toast.makeText(getApplicationContext(),"Error Loading Image",Toast.LENGTH_LONG).show();
 
 else 
 Toast.makeText(getApplicationContext(),"Please select an image",Toast.LENGTH_LONG).show();
 

I've seen some posts which use from and to to rename Images but I'm not able to understand how it works and how to set a desired name(which will be entered by user via an editText).

Any help would be appreciated

Here is the code which may help you

 File sdcard = Environment.getExternalStorageDirectory();
 File from = new File(sdcard, "from.txt");
 File to = new File(sdcard, "to.txt");
 if (updateFileName(context, from, to))
 Log.d("File Rename", "Successfully renamed");
 else Log.d("File Rename", "Rename filed");

 public static boolean updateFileName(Context mContext, File from, File to) 
 if (from.renameTo(to)) 
 removeMedia(mContext, from);
 updateMediaInGallery(mContext, to);
 return true;
 else 
 return false;
 
 

 public static void updateMediaInGallery(Context c, File f) 
 Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
 intent.setData(Uri.fromFile(f));
 c.sendBroadcast(intent);
 

 private static void removeMedia(Context c, File f) 
 ContentResolver resolver = c.getContentResolver();
 resolver.delete(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.Media.DATA + "=?", new Stringf.getAbsolutePath());
 

Here you can find your relevant solution of @Davewebb and you are confused in from to

File sdcard = Environment.getExternalStorageDirectory();
File from = new File(sdcard,"from.txt");
File to = new File(sdcard,"to.txt");
from.renameTo(to);

from.txt is your old name and new name will be here is to.txt

for internal Storage, you can read a file like this and will do the same above process

private String readFileFromInternalStorage()
ImageView imageView = (ImageView) findViewById(R.id.image);
ContextWrapper cw = new ContextWrapper(context);

//path to /data/data/yourapp/app_data/dirName
File directory = cw.getDir("dirName", Context.MODE_PRIVATE); 
File mypath=new File(directory,"imagename.jpg");

ImageView imageView = (ImageView) findViewById(R.id.image);
 imageView.setImageDrawable(Drawable.createFromPath(mypath.toString()));
