使用安卓 studio和mysql进行第二次照片更新的java

Question

我在安卓 studio和mysql中更新照片档案时遇到了一些问题。但对于数据库更新的过程来说没有问题，照片更新成功。第一次在imageview中更新照片配置文件成功更改，并将照片上传到xampp内的文件夹“upload”，第二次更新不会更改，而是在imageview中使用上一次更新。但在xampp内的文件夹“upload”中，以前的照片会随着我以前上传的新照片而改变。我试图用onRestart（）刷新活动，但失败了，希望您理解我的问题。请帮帮我

here the php code :

    <?php
    include "koneksi.php";

    $gambar = $_POST['foto'];
    $id = $_POST['id_user'];


    class emp{}

    $path = "profil_upload/$id.png";
    $actualpath = "http://192.168.173.1/StudioFoto/$path";

    $query = mysql_query("UPDATE user SET foto='".$actualpath."' WHERE id='".$id."'");

        if ($query) {
            file_put_contents($path,base64_decode($gambar));
            $response = new emp();
            $response->success = 1;
            $response->message = "Data berhasil di simpan";
            die(json_encode($response));
        } else{ 
            $response = new emp();
            $response->success = 0;
            $response->message = "Error simpan Data";
            die(json_encode($response)); 
        }   

?>

here method for upload:

private void uploadImage() {

    StringRequest strReq = new StringRequest(Request.Method.POST, url_update_foto, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            Log.d(TAG, "Response: " + response.toString());

            try {
                JSONObject jObj = new JSONObject(response);
                success = jObj.getInt(TAG_SUCCESS);

                // Cek error node pada json
                if (success == 1) {
                    Log.d("Insert", jObj.toString());
                    Toast.makeText(UploadFoto.this, jObj.getString(TAG_MESSAGE), Toast.LENGTH_LONG).show();

                } else {
                    Toast.makeText(UploadFoto.this, jObj.getString(TAG_MESSAGE), Toast.LENGTH_LONG).show();
                }
            } catch (JSONException e) {
                // JSON error
                e.printStackTrace();
            }

        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e(TAG, "Error: " + error.getMessage());
            Toast.makeText(UploadFoto.this, error.getMessage(), Toast.LENGTH_LONG).show();
        }
    }) {

        @Override
        protected Map<String, String> getParams() {
            // Posting parameters ke post url
            Map<String, String> params = new HashMap<>();

            //Converting Bitmap to String
            String image = getStringImage(bitmap);

            //Adding parameters
            params.put("foto", image);
            params.put("id_user", id);
            return params;
        }

    };

    AppController.getInstance().addToRequestQueue(strReq, tag_json_obj);
