android - Res cannot be resolved with an ImageView -


I have a ImageView in my Android app I ImageView as a button of'm using when I pressed the button, then you should change the image in my code, it says Rhys can not be solved . My code is below: 

  loginbtn.setOnClickListener (btnOnClickListener); Here, according to // convert images loginbtn.setOnTouchListener touch (New OnTouchListener () {@Override public boolean onTouch (see v, MotionEvent ARG1) {// TODO Auto-generated method stub // switch (arg1.getAction ()) {case MotionEvent.ACTION_DOWN: break {v.setImageBitmap (res.getDrawable (R.drawable.compare_now_click)); // Race break;} case MotionEvent.ACTION_CANCEL: {v.setImageBitmap (. res.getDrawable (R.drawable));; }} Return true, return;}});   
 On the line:  
  v.setImageBitmap (res.getDrawable (R.drawable.compare_now_click));   
 I'm getting the error  res can not be resolved . Why this may be happening   
 
 
 use instead :?  
  ((imageView) v) .setImageResource (R.drawable.compare_now_click);   
 Otherwise, you must first obtain the resource from the context, e.g. If you are in a  activity , use the  resource race = getResources ();   
 Also, does not meet your other image processing ID:  R.drawable

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
