I want display Review text and its Rating in another activity.
Here is my AddReview class
public class AddReview extends AppCompatActivity implements ServerRequests.AddReviewreponse {
private Button submit;
EditText addReview;
RatingBar ratingBar;
Toolbar toolbar;
ServerRequests serverRequests;
JSONParser jsonParser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_review);
jsonParser = new JSONParser();
serverRequests = new ServerRequests(getApplicationContext());
serverRequests.setAddReviewreponse(this);
addReview=(EditText)findViewById(R.id.reviewBox);
ratingBar=(RatingBar) findViewById(R.id.ratingBar);
submit=(Button)findViewById(R.id.submit);
toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar_top);
setSupportActionBar(toolbar);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle("Add Review");
// toolbar.setNavigationIcon(R.drawable.back_30);
/* toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onBackPressed();
}
});*/
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
String ReviewTxt = addReview.getText().toString();
float rating = ratingBar.getRating();
JSONObject obj = jsonParser.makeAddReviewJson(1,1,ReviewTxt,rating);
Log.e("final Json", obj.toString());
serverRequests.addReview(obj);
} catch (Exception e) {
}
/* Reviews.displayName.setText(RegisterActivity.name.getText().toString());
Reviews.displayReview.setText("Your Review : "+addReview.getText().toString());
Reviews.displayStars.setRating(ratingBar.getRating());*/
/* Reviews.displayStars.setText("Your Rating : " + ratingBar.getRating());
String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
Reviews.displayDate.setText(currentDateTimeString);*/
AlertDialog alertDialog = new AlertDialog.Builder(AddReview.this).create();
alertDialog.setTitle("Review Submitted!");
alertDialog.setMessage("Thanks for your valueable review!");
alertDialog.setIcon(R.drawable.star_48);
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to execute after dialog closed
Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
// startActivity(new Intent(getApplicationContext(), Reviews.class));
}
});
// Showing Alert Message
alertDialog.show();
}
});
}
@Override
public void onAddReviewReposne(JSONObject object) {
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==android.R.id.home)
{
finish();
}
return super.onOptionsItemSelected(item);
}
}
This is the Review class where I want to display the review and its ratings
public class Reviews extends AppCompatActivity implements ServerRequests.GetReviewResponse {
public static TextView displayReview, displayDate, displayName;
public static RatingBar displayStars;
Button addReviewBtn;
android.support.v7.widget.Toolbar toolbar;
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private static String LOG_TAG = "CardViewActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reviews);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view1);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
// mAdapter = new ReviewAdapter(getDataSet(jsonObject));
mRecyclerView.setAdapter(mAdapter);
toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar_top1);
setSupportActionBar(toolbar);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle("Reviews");
/*displayReview = (TextView) findViewById(R.id.review);
displayStars = (RatingBar) findViewById(R.id.rating);
displayDate = (TextView)findViewById(R.id.displayDate);
displayName = (TextView)findViewById(R.id.displayName);*/
addReviewBtn = (Button)findViewById(R.id.addReviewBtn);
addReviewBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(getApplicationContext(), AddReview.class));
}
});
ServerRequests serverRequests=new ServerRequests(getApplicationContext());
serverRequests.setReviewResponse(this);
serverRequests.getReviews("one");
}
private ArrayList<Review> getDataSet(JSONArray array) {
ArrayList results = new ArrayList<Review>();
for (int i = 0; i < array.length(); i++) {
try {
JSONObject object = array.getJSONObject(i);
Review obj = new Review(object.getInt("reviewId"),object.getInt("userId"),object.getString("Name"),object.getString("Review"),object.getLong("rating"));
results.add(i,obj);
}
catch (Exception e){
e.printStackTrace();
}
}
return results;
}
@Override
public void onGetReviewResponse(JSONArray jsonObject) {
mAdapter = new ReviewAdapter(getDataSet(jsonObject));
mRecyclerView.setAdapter(mAdapter);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==android.R.id.home)
{
finish();
}
return super.onOptionsItemSelected(item);
}
}
This is the ReviewAdapter
public class ReviewAdapter extends RecyclerView.Adapter<ReviewAdapter.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<Review> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public static TextView name,review;
public static RatingBar rating;
public DataObjectHolder(View itemView) {
super(itemView);
name = (TextView) itemView.findViewById(R.id.name);
review = (TextView) itemView.findViewById(R.id.review);
rating = (RatingBar) itemView.findViewById(R.id.rating);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
@Override
public void onClick(View v) {
myClickListener.onItemClick(getAdapterPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public ReviewAdapter(ArrayList<Review> myDataset) {
mDataset = myDataset;
}
@Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view_review, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
@Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.name.setText(mDataset.get(position).getName());
holder.review.setText(mDataset.get(position).getReview());
holder.rating.setRating(mDataset.get(position).getRating());
}
public void addItem(Review dataObj, int index) {
mDataset.add(index, dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
@Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
This is the Pojo class of Review
public class Review {
private String name,review;
private float rating;
private int reviewId,userId;
public Review (int ReviewId, int UserId, String Name, String Review, float Rating){
reviewId = ReviewId;
userId = UserId;
name = Name;
review = Review;
rating = Rating;
}
public int getReviewId() {
return reviewId;
}
public void setReviewId(int reviewId) {
this.reviewId = reviewId;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getReview() {
return review;
}
public void setReview(String review) {
this.review = review;
}
public float getRating() {
return rating;
}
public void setRating(float rating) {
this.rating = rating;
}
}
This is the ServerRequests for add and get Review
//------------For add review------------------------------
public void setAddReviewreponse(AddReviewreponse addreviewreponse) {
this.addreviewreponse = addreviewreponse;
}
private AddReviewreponse addreviewreponse;
public interface AddReviewreponse {
void onAddReviewReposne(JSONObject object);
}
public void addReview(JSONObject jsonObject) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, Services.ADD_REVIEW, jsonObject,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
Log.e("Json response", "" + response);
boolean b = response.getBoolean("success");
if (addreviewreponse != null) {
addreviewreponse.onAddReviewReposne(response);
}
} catch (Exception e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("Error ", "" + error);
}
}
);
queue.add(jsonObjectRequest);
}
//------------For get review------------------------------
public void setReviewResponse(GetReviewResponse reviewResponse) {
this.getReviewResponse = reviewResponse;
}
public GetReviewResponse getReviewResponse;
public interface GetReviewResponse {
void onGetReviewResponse(JSONArray jsonObject);
}
public void getReviews(final String id) {
StringRequest request = new StringRequest(Request.Method.GET, Services.GET_REVIEW,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONArray array = new JSONArray(response);
Log.e("Server response", response);
if (array.length() > 0) {
if (getReviewResponse != null) {
getReviewResponse.onGetReviewResponse(array);
}
} else {
Log.e("Error is occured", "asd");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
//send error repsonse back to user
Log.e("Error: ", error.getMessage());
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<>();
params.put("courseId", id);
return params;
}
};
queue.add(request);
}
This is JSONParser class for AddReview
//--------For Add review---------------------------------
public JSONObject makeAddReviewJson(int studentID, int courseID, String reviewTxt, float rating) throws JSONException {
JSONObject object = new JSONObject();
object.put("studentId", studentID);
object.put("courseId", courseID);
object.put("review", reviewTxt);
object.put("ratings", rating);
return object;
}
This is the JSON response I am getting after posting the Review
E/final Json: {"studentId":1,"courseId":1,"review":"Hellooooo","ratings":3}
E/Json response: {"success":true,"msg":"Your review has been added successfully","data":{"reviewsId":18}}
