I am having trouble getting the earlier class objects of an array list in the 'onPostExecute' method of my asynch class. To simplify things for this post, I'm just trying to set the text of the 'name' to my textview in my onPostExecute method like so.
myTextView.setText(VideoDetail_List.get(0).getVideoName());
However the problem is that the String that is returning is the last instance of the videoname object in the string array, instead of the first instance of the video name, which should be the child class object of the VideoDetail_List at the 0 index.
AsyncTask Class
final JSONObject obj = new JSONObject(result);
final JSONArray videoData = obj.getJSONArray("data");
final int n = videoData.length();
for (int i = 0; i < n; ++i) {
final JSONObject video = videoData.getJSONObject(i);
videoDetail.setVideoName(video.getString("name"));
videoDetail.setVideoDuration(video.getString("duration"));
final JSONObject videoPictures = video.getJSONObject("pictures");
final JSONArray videoPictureSizes = videoPictures.getJSONArray("sizes");
final JSONObject videoPictureLink = videoPictureSizes.getJSONObject(1);
videoDetail.setPictureLink(videoPictureLink.getString("link"));
//pictureLink.add(videoPictureLink.getString("link"));
final JSONArray videoURLTypes = video.getJSONArray("download");
final JSONObject videoURLLink = videoURLTypes.getJSONObject(0);
videoDetail.setVideoLink(videoURLLink.getString("link"));
//videoLink.add(videoURLLink.getString("link"));
VideoDetail_List.add(i,videoDetail);
}
return VideoDetail_List;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
#Override
protected void onPostExecute(List<VideoDetail> VideoDetail_List) {
System.out.println("RESPONSE: " + VideoDetail_List);
final TextView myTextView = new TextView(mContext);
myTextView.setText(VideoDetail_List.get(0).getVideoName());
mLayout.addView(myTextView);
myTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String sText = myTextView.getText().toString();
//Toast toast = Toast.makeText(this, sText, Toast.LENGTH_SHORT);
Toast toast = Toast.makeText(mContext, sText, Toast.LENGTH_LONG);
toast.show();
}
});
}
VideoDetail Class
public class VideoDetail {
private String videoName;
private String videoDuration;
private String pictureLink;
private String videoLink;
public String getVideoName() {
return this.videoName;
}
public void setVideoName(String videoName) {
this.videoName = videoName;
}
public String getVideoDuration() {
return videoDuration;
}
public void setVideoDuration(String videoDuration) {
this.videoDuration = videoDuration;
}
public String getPictureLink() {
return pictureLink;
}
public void setPictureLink(String pictureLink) {
this.pictureLink = pictureLink;
}
public void setVideoLink(String videoLink){
this.videoLink = videoLink;
}
public String getVideoLink() {
return videoLink;
}
}
Thank you in advance for your help!
However the problem is that the String that is returning is the last
instance of the videoname object in the string array
That's because you are overriding the content of the only instance of VideoDetails at every iteration of your for loop. You should instantiate it at every iteration
for (int i = 0; i < n; ++i) {
videoDetail = new VideoDetail();

Here is my MentionsAdapter where I want to setText the Mentions Array

public ViewHolder(View view) {
super(view);
ivProfile = (ImageView) view.findViewById(R.id.ivAva);
tvUsername = (TextView) view.findViewById(R.id.tvName);
tvMentions = (TextView) view.findViewById(R.id.tvMentions);
tvMentionsDate = (TextView) view.findViewById(R.id.tvMentionsDate);
view.setOnClickListener(this);
}
#Override

#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

LayoutInflater inflater = LayoutInflater.from(context);

#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Log.d("debug", "int:: " + position);
Tweet tweet = lTweets.get(position);
holder.tvMentionsDate.setText(tweet.getRelativeTimeAgo());
holder.tvUsername.setText(tweet.getUser().getName());
holder.tvMentions.setText(tweet)
holder.ivProfile.setImageResource(android.R.color.transparent);
Glide.with(context).load(tweet.getUser().getProfileImageUrl()).into(holder.ivProfile);
}
#Override
public int getItemCount() {
if(lTweets == null){
Log.d("debug", "null");
return 0;
}
else {
Log.d("debug", ":: " + lTweets.size());
return lTweets.size();
}
}
}
Thanks in advance.
you can get mentions data from tweet by following
User user = tweet.getMentions();
so that you can get user object from that.same way you can get all user instances from here by using
user.getMethodName()
just update the above code in onBindViewHolder().
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Log.d("debug", "int:: " + position);
Tweet tweet = lTweets.get(position);
User user = tweet.getMentions();
holder.tvMentionsDate.setText(tweet.getRelativeTimeAgo());
holder.tvUsername.setText(tweet.getUser().getName());
holder.tvMentions.setText(tweet)
holder.ivProfile.setImageResource(android.R.color.transparent);
Glide.with(context).load(tweet.getUser().getProfileImageUrl()).into(holder.ivProfile);
}
If i am not wrong u want to add data to your ArrayList which is of type Tweet this can be done like this
yourArrayList.add(new Tweet ("Parameters goes here");
hope this helps
if I understand correctly you just want to display the number of mentions.
you can do this:
holder.tvMentions.setText(Integer.toString(tweet.getMentions().size()));
Ahh Well I fix with my answer just by adding some line :
twt.textMentions = jsonObject.getString("text");
Anyway thanks everyone for the answers
I have an array as shown below
private ArrayList<Blogs> parseJSONResponseCar(JSONArray response) {
if (!response.equals("")) {
try {
StringBuilder data = new StringBuilder();
for (int i = 0; i < response.length(); i++) {
JSONObject currentQuestions = response.getJSONObject(i);
String Blue = currentQuestions.getString("text");
String Yellow=currentQuestions.getString("id");
How can I extract the getString("id") value and put it in a new OnClick Listener method??
public void OnUp (View view) {}
Use a global class variable outside function like this:
string globalVar = "";
private ArrayList<Blogs> parseJSONResponseCar(JSONArray response) {
String Yellow=currentQuestions.getString("id");
globalVar = Yellow;
}
public void OnUp (View view) {
string test = globalVar ;
}
If its a web application you can store in Session.
I am using an AsyncTask to connect to the following URL:
https://api.themoviedb.org/3/movie/upcoming?api_key=6572f232190d6b55ec917726dab87783
One of the values I am having trouble with is the genre_id. As it is a JSONArray I add the values to an ArrayList. I then later want to convert these values to the String correspondence which are found here:
http://api.themoviedb.org/3/genre/movie/list?api_key=6572f232190d6b55ec917726dab87783
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre_ids");
ArrayList<Integer> genre = new ArrayList<Integer>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add(genreArry.optInt(j));
}
I'm just wondering what is the best way to do this? I am a displaying a ListView of all the information and for each row all the information is correct. I just need to convert the Genre id into the corresponding String. I have tried the code below but the TextView is always overwritten by the last value. Does anyone know of a better way to do this?
private void getGenre(int genre) {
for (int i = 0; i < genreList.size(); i++) {
Log.d("THE", "THE GENRE ADAPTER RETRIEVED IS" + i + genreList.get(i).getId() + genreList.get(i).getName());
if (genreList.get(i).getId() == genre) {
String name = genreList.get(i).getName();
mGenre.setText(name);
}
}
Solved.
I managed to get this working by doing a check in the onPostExecute of my AsyncTask
try {
JSONObject json = new JSONObject(result);
JSONArray movies = json.getJSONArray("results");
for (int i = 0; i < movies.length(); i++) {
JSONObject obj = movies.getJSONObject(i);
//Create Movie Object
Movie movie = new Movie();
//get values from JSON
movie.setTitle(obj.getString("original_title"));
movie.setPopularity(obj.getString("popularity"));
movie.setYear(obj.getString("release_date"));
movie.setThumbnailUrl(obj.getString("poster_path"));
movie.setOverView(obj.getString("overview"));
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre_ids");
ArrayList<Integer> genre = new ArrayList<Integer>();
ArrayList<String> genreName = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add(genreArry.optInt(j));
for (int zz = 0; zz < myGenreList.size(); zz++) {
if (myGenreList.get(zz).getId() == genre.get(j)) {
String name = myGenreList.get(zz).getName();
genreName.add(name);
}
}
}
movie.setGenre(genre);
movie.setGenreName(genreName);
I prefer Volley instead of AsyncTask for simplicity, but you are more than welcome to use either. Note, AsyncTask will require quite a bit more work.
From what I have provided here, you should be able to get my screenshot after building the ListView item XML.
I loosely followed this guide to get started quickly.

I am trying to pass a string to function removeWords() and this function removes some information from the String.
For example if I pass:
"I Have a Headach"
the function should return:
"Headach"
However, my function is not working:
public class WordChosen extends Activity {
private TextView wordsList;
private String symptom;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_word_chosen);
//Getting String from VoiceRecognition Activity and displaying it
Intent intent = getIntent();
String wordChosen = intent.getExtras().getString("wordChosen");
//casting the string with TextView to display the result
wordsList = (TextView) findViewById(R.id.wordChosen);
Log.v("Word List:", "+++++"+wordChosen);
//Setting text to be displayed in the textView
removeWords(wordChosen);
Log.v("removewords:", "------- message is displayed");
}
public void removeWords(String wordList)
{
ArrayList<String> stopList = null;
stopList.add("i");
stopList.add("have");
stopList.add("a");
ArrayList<String> result = new ArrayList<String>(Arrays.asList(wordList.split(" ")));
for(int i=0; i<result.size();i++)
{
for(int j=0; j<stopList.size();j++)
{
if (result.get(i).equals(stopList.get(j))) {
break;
}
else {
if(j==stopList.size()-1)
{
wordsList.setText(result.get(i));
}
}
}
}
}
}
public static void main(String[] args) {
String word = "I Have a Headach";
String remove = "I Have a ";
System.out.println(removeWords(word, remove));

});
}
}
});
So here in this part of the code i get error while iterating the child elements .
Any help will be greatfull
I Solved this issue by a for loop, which will add the child to the new "mOpenOrderSelected" variable:
if (objOpenOrders.isChecked()) {
isSelectedOrderNumber++;
sb.append(objOpenOrders.getOrderID());
sb.append(",");
final OpenOrders parent = new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName());
ArrayList<Child> mOpenOrderItems=objOpenOrders.getChildren();
parent.setChildren(new ArrayList<Child>());
for(int k=0; k<mOpenOrderItems.size(); k++){
final Child child = (Child) mOpenOrderItems.get(k);
Log.d("ChildItemsname", "ChildItemsname:"+child.getName());
parent.getChildren().add(child);
}
mOpenOrdersSelected.add(parent);
}
So the new button click code will be like this:
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(mAdapter != null) {
int isSelectedOrderNumber=0;//This Variable will check with the parameter passed from server
mOpenOrdersSelected = new ArrayList<OpenOrders>();
StringBuffer sb = new StringBuffer();
Iterator<OpenOrders> it = mOpenOrders.iterator();
while(it.hasNext())
{
OpenOrders objOpenOrders = it.next();
//Do something with objOpenOrders
if (objOpenOrders.isChecked()) {
isSelectedOrderNumber++;
sb.append(objOpenOrders.getOrderID());
sb.append(",");
final OpenOrders parent = new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName());
ArrayList<Child> mOpenOrderItems=objOpenOrders.getChildren();
parent.setChildren(new ArrayList<Child>());
for(int k=0; k<mOpenOrderItems.size(); k++){
final Child child = (Child) mOpenOrderItems.get(k);
Log.d("ChildItemsname", "ChildItemsname:"+child.getName());
parent.getChildren().add(child);
}
mOpenOrdersSelected.add(parent);
}
}
//Below Condition Will Check the selected Items With parameter passed "mMAX_ORDERS_TOBEPICKED"
if(isSelectedOrderNumber<1){
ShowErrorDialog("Please Select atleast One order");
return;
}
if(isSelectedOrderNumber>mMAX_ORDERS_TOBEPICKED){
ShowErrorDialog(" Select Maximum of "+mMAX_ORDERS_TOBEPICKED+ " Orders only to process");
return;
}
