Cannot cast Int to android.view.View using Transition in Adapter class

Question

Am trying to use transitions in my App but am facing this problem,

Cannot cast Int to android.view.View

Below is my code:

holder.newsRoot.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent newsIntent = new Intent(NewsAdapter.this.c, NewsDetails.class);

                newsIntent.putExtra("newstitle",NewsTitle);
                newsIntent.putExtra("detailednews",DetailedNews);
                newsIntent.putExtra("newsdate",NewsDate);
                newsIntent.putExtra("newsphoto",NewsPhoto);


                ActivityOptionsCompat options= ActivityOptionsCompat.makeSceneTransitionAnimation(this,(View)news_image,"image_transit");

                c.startActivity(newsIntent,options.toBundle());

            }
        });

Am trying to integrate it in the Adapter class, but this is the line where the problem is :

`ActivityOptionsCompat options= ActivityOptionsCompat.makeSceneTransitionAnimation(this,(View)news_image,"image_transit")`;

** problem is found on these words**

(View)news_image

My xml code of the ImageView.

 <ImageView

                android:id="@+id/news_image"
                android:layout_width="80dp"
                android:transitionName="image_transit"
                android:layout_height="80dp"
                android:src="@drawable/bbb"/>

Please share some code where you define/set `news_image`. Like this it looks like it might actually be a view ID, but not a real view. — Mauin, Jan 30 '17 at 14:56
I have some *news* for you. You didn't show us what `news_image` is! — Chetan Kinger, Jan 30 '17 at 14:57
`Cannot cast Int to android.view.View` simply mean that you are trying to cast a integer into a View, so `news_image` is a `int`. Google the excpetion first to understand what it means, than search the problem. — AxelH, Jan 30 '17 at 14:58
You didn't show where you declared and initialize `news_image`, the XML only set the value of `R.id.news_image` — AxelH, Jan 30 '17 at 15:02

PROBLEM: in android, you store the id's of your objects as int, but the int is the view id, not the view itself.

SOLUTION: in order to work with it you need to get the view use findViewById.

ImageView yourImageView = (ImageView) findViewById(R.id.news_image);

In your case you can also use it directly in the problematic method:

ActivityOptionsCompat options= 
      ActivityOptionsCompat.makeSceneTransitionAnimation(this,  
                                                         findViewById(R.id.news_image),
                                                         "image_transit")`;

Because you placed it in the xml layout:

<ImageView android:id="@+id/news_image"

Good guess. Hope it goes through. – Chetan Kinger Jan 30 '17 at 14:58
But remember am inside an Adapter class where my intent is , please can you try to edit my code with your answer – Fauzia Nito Jan 30 '17 at 15:01
@JordiCastilla, is a v an Int or View – Fauzia Nito Jan 30 '17 at 15:04
v is the view of the event: `public void onClick(View v) {` but is just an example, let me update the code – Jordi Castilla Jan 30 '17 at 15:05
Is it supposed to be Int v =(View) findViewById(R.id.news_image); or – Fauzia Nito Jan 30 '17 at 15:05
*Ok please update my code that will be better*, sorry, stackoverflow does not work in this way, you can edit your question to clarify, but not to change main theme of it, also I can't edit your code. Please look at my updated answer. – Jordi Castilla Jan 30 '17 at 15:08
Sorry i didnt mean editing my code , just wanted you to edit your answer according to my code – Fauzia Nito Jan 30 '17 at 15:17
`findViewById` cannot be resolved why ? is there any problem @JordiCastilla – Fauzia Nito Jan 30 '17 at 15:18
sure is some problem, but I have not enough information, look at the [**link**](https://developer.android.com/reference/android/view/View.html#findViewById(int)) I posted. As you can see is a `View` or `Activity` method and it states: *retrieve it with `View.findViewById()` or `Activity.findViewById()`*, that makes me ask..... **are you executing this in a View or Activity?**, please, **read complete and carefully my answer** and also link provided, **after this** if you have any doubts don't hesitate to ask, but show a bit of effort. – Jordi Castilla Jan 30 '17 at 15:22
