어떤 값이'url'에 대한 사용을 클릭 버튼에 대한 새로운 MySingleton 클래스

public class MySingleton{ private static MySingleton mInstance; private RequestQueue mRequestQueue; private ImageLoader mImageLoader; private static Context mCtx; private MySingleton(Context context) { mCtx = context; mRequestQueue = getRequestQueue(); mImageLoader = new ImageLoader(mRequestQueue, new ImageLoader.ImageCache() { private final LruCache<String, Bitmap> cache = new LruCache<String, Bitmap>(20); @Override public Bitmap getBitmap(String url) { return cache.get(url); } @Override public void putBitmap(String url, Bitmap bitmap) { cache.put(url, bitmap); } }); } public static synchronized MySingleton getInstance(Context context) { if (mInstance == null) { mInstance = new MySingleton(context); } return mInstance; } public RequestQueue getRequestQueue() { if (mRequestQueue == null) { // getApplicationContext() is key, it keeps you from leaking the // Activity or BroadcastReceiver if someone passes one in. mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext()); } return mRequestQueue; } public <T> void addToRequestQueue(Request<T> req) { getRequestQueue().add(req); } public ImageLoader getImageLoader() { return mImageLoader; } public void cancelPendingRequests(Object tag) { if (mRequestQueue != null) { mRequestQueue.cancelAll(tag); } } }

전화를 만들? – TWL

StringRequest stringRequest = new StringRequest(Request.Method.POST,url, 
        new Response.Listener<String>() { 
         @Override 
         public void onResponse(String response) { 
          Log.d("---response--", "" + response); 
         } 
        }, 
        new Response.ErrorListener() { 
         @Override 
         public void onErrorResponse(VolleyError error) { 
          Log.d("error---", "" + error.toString()); 
         } 
        }) { 
       @Override 
       protected Map<String, String> getParams() { 
        Map<String, String> params = new HashMap<String, String>(); 

        params.put("date",String.valueOf(myText)); 
        params.put("email", "[email protected]");

      }; 
      MySingleton.getInstance(Expenses_Add.this).addToRequestQueue(stringRequest);
