Activity cannot be cast to Interface (ClassCastException)

Activity cannot be cast to Interface (ClassCastException) - java

I'm currently getting a ClassCastException in my android app caused by "activity cannot be cast to interface".
Here is my code:
Logcat says the Exception is thrown in the onAttach part in MovieGridFragment on the line "this.clickListener = (clickInterfaceHelper) context;".
My Interface:
public interface clickInterfaceHelper {
void clickOnItem(int id);
void favoriteMovieItem(int movieId); }
The Fragment Class:
public class MovieGridFragment extends Fragment {
public clickInterfaceHelper clickListener;
private int index;
private GridView movieGridView;
public List<movieData> movieDataList = new ArrayList<>();
public MovieGridFragment() {} //empty constructor
#Override
public void onAttach(Context context) {
this.clickListener = (clickInterfaceHelper) context;
super.onAttach(context);
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
if(savedInstanceState != null) {
if (!movieDataList.isEmpty()) {
movieDataList = Arrays.asList((movieData[]) savedInstanceState.getSerializable("OLDMOVIEDATA"));
}
}
super.onCreate(savedInstanceState);
}
The MainActivity:
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.movie_display_fragment, container, false);
movieGridView = (GridView) rootView.findViewById(R.id.gv_movie_display);
movieAdapter adapter = new movieAdapter(getActivity(),movieDataList);
adapter.notifyDataSetChanged();
movieGridView.setAdapter(adapter);
movieGridView.setSelection(index);
movieGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if(clickListener != null)
clickListener.clickOnItem(position);
}
});
return rootView;
}
#Override
public void onSaveInstanceState(Bundle outState) {

outState.putSerializable("OLDMOVIEDATA",movieData.movieDataArray);

You can try this
this.clickListener = (MainActivity) getActivity();
You get the FragmentActivity and cast it into your MainActivity
EDIT:
I suggest you to add a function in your fragment like :
public void setListener(clickInterfaceHelper listener) {
this.clickListener = listener;
}
And in your activity :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(savedInstanceState == null) {
MovieGridFragment fragment = new MovieGridFragment();
fragment.setListener(this); // some change here
getSupportFragmentManager().beginTransaction()
.add(R.id.activity_container, fragment)
.commit();
movieData.movieDataPosition = 0;
}
if(savedInstanceState != null) {
sorterString = savedInstanceState.getString("SORTER");
}
if(savedInstanceState == null)
movieData.movieDataPosition = 0;
if(sorterString==null)
sorterString="popular?";
if(sorterString!="favorite" && sorterString!=null) {
if(networkChecker.isNetworkAvailableChecker(this)) {
movieRequest();
}
}
}
.... no relevant functions
public void movieRequest() {
urlFinal = urlBase + sorterString + movieData.apiKey;
urlFinal.trim();
requestQueue = Volley.newRequestQueue(this);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, urlFinal, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray array = response.getJSONArray("results");
movieData.movieDataArray = new movieData[array.length()];
for (int i = 0; i < array.length(); i++) {
movieData movie = new movieData();
JSONObject jsonObject = array.getJSONObject(i);
//movie.setPosition(i);
movie.setMovieId(jsonObject.getString("id"));
movie.setMovieImagePath(jsonObject.getString("poster_path"));
movie.setMovieTitle(jsonObject.getString("original_title"));
movie.setMoviePlot(jsonObject.getString("overview"));
movie.setMovieVoting(jsonObject.getString("vote_average"));
movie.setMovieReleaseDate(jsonObject.getString("release_date"));
movieData.movieDataArray[i] = movie;
}
MovieGridFragment gridFragment = new MovieGridFragment();
gridfragment.setListener(this); // some change here
gridFragment.movieDataList = Arrays.asList(movieData.movieDataArray); //hier wird datalist eigentlich zugewiesen
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.activity_container, gridFragment);
try {
transaction.commitAllowingStateLoss();
} catch (Exception e) {
e.printStackTrace();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override

Hope this helps.

The context passed in is not necessarily your activity. It could be a wrapper around it with various theming and other overrides. You can never assume that when passed a Context, you're passed an Activity. If you need a reference to a click handler, write a setClickHandler function and call it explicitly.
Even if it is the Activity, the app doesn't know that- at that point its a Context. You'd need to explicitly cast it, which may not work (and may work on some versions of the OS and not others) due to paragraph 1.

Try to put your interface inside fragment class.
public class MovieGridFragment extends Fragment {
public clickInterfaceHelper clickListener;
private int index;
private GridView movieGridView;
public List<movieData> movieDataList = new ArrayList<>();
public MovieGridFragment() {} //empty constructor
#Override
public void onAttach(Context context) {
this.clickListener = (clickInterfaceHelper) context;
super.onAttach(context);
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
if(savedInstanceState != null) {
if (!movieDataList.isEmpty()) {
movieDataList = Arrays.asList((movieData[]) savedInstanceState.getSerializable("OLDMOVIEDATA"));
}
}
super.onCreate(savedInstanceState);
}
public interface clickInterfaceHelper {
void clickOnItem(int id);
void favoriteMovieItem(int movieId);
}
}

To all android beginners, you can use the interface like below-mentioned way.
Define an Interface,
public interface CallBack {
String stringValue(String s);
}
In Fragment,
Callback mCallback;
In onAttach(Context context) method of your fragment,
mCallback = (Callback) context; // Casting to the activity
mcallback.stringValue("Your message");
Then in your Activity, you must implement the interface else you will get
classcastException
public class MainActivity implements CallBack{
#Override
public String stringValue(String s) {
// Here you will get the value from the fragment
return s;
}
}
It's not advisable to pass values between two fragments directly using interfaces. You should use the activity as a mediator while passing values.

When you are going to filter like this
Filter filter = mTextTypingCustomAdapter.getFilter();
if not match with any item.then your variable mTextTypingCustomAdapter is null. you should check null safety before filtering in both methods( onQueryTextSubmit() && onQueryTextChange() )
if(mTextTypingCustomAdapter != null){
Filter filter = mTextTypingCustomAdapter.getFilter();}

there you start with try:

which has to continue with:
try {

} catch(Exception e) {
} finally {

where either catch or finally are optional (depending where the Exception shall be handled).

Save the exoplayer streaming position and text on screen rotation and also the video should not paused
