Use fetched data from Json for other Json parse

Use fetched data from Json for other Json parse - android

https://launchlibrary.net/1.3/launch shows json data. If you paste the id after this url, there is more in depth information about the launch, for example https://launchlibrary.net/1.3/launch/2053.
I want to get the image url of the corresponding launch but it doesn't work how I'm doing it. This is the code from where I parse the JSON data.
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
v = inflater.inflate(R.layout.activity_launches, container, false);
myRecyclerView = (RecyclerView) v.findViewById(R.id.recycler_view);
myRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
launchesList = new ArrayList<>();
temporaryList = new ArrayList<>();
myRequestQueue = Volley.newRequestQueue(getContext());
parseJSON();
return v;
}
private void parseJSON(){
String url = "https://launchlibrary.net/1.3/launch";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("launches");
for(int i = 0; i < jsonArray.length(); i++){
JSONObject launch = jsonArray.getJSONObject(i);
String launchName = launch.getString("name");
String launchDate = launch.getString("net");
launchId = launch.getString("id");
String imageUrl = getImageUrl();
Launch newLaunch = new Launch(launchName, launchDate, imageUrl);
launchesList.add(newLaunch);
}
myRecyclerViewAdapter = new RecyclerViewAdapter(getContext(), launchesList);
myRecyclerView.setAdapter(myRecyclerViewAdapter);
myRecyclerViewAdapter.setOnItemClickListener(LaunchesActivity.this);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
myRequestQueue.add(request);
}
public String getImageUrl(){
String url = "https://launchlibrary.net/1.3/launch/" + launchId;
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("launches");
JSONObject launch = jsonArray.getJSONObject(0);
JSONObject rocket = launch.getJSONObject("rocket");
String url = rocket.getString("imageURL");
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
myRequestQueue.add(request);
return url;
}
This is the adapter I created to change the text in the TextViews and ImageView.
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.RecyclerViewHolder>{
private Context myContext;
private ArrayList<Launch> launchList;
private OnItemClickListener myListener;
public interface OnItemClickListener{
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener){
myListener = listener;
}
public RecyclerViewAdapter(Context context, ArrayList<Launch> launchList){
myContext = context;
this.launchList = launchList;
}
#NonNull
#Override
public RecyclerViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(myContext).inflate(R.layout.launch_item, parent, false);
return new RecyclerViewHolder(v);
}
#Override
public void onBindViewHolder(#NonNull RecyclerViewHolder holder, int position) {
Launch currentItem = launchList.get(position);
String name = currentItem.getName();
String date = currentItem.getDate();
String imageUrl = currentItem.getImageUrl();
holder.myTextViewName.setText(name);
holder.myTextViewDate.setText(date);
Picasso.get().load(imageUrl).fit().centerInside().into(holder.myImageViewImage);
}
#Override
public int getItemCount() {
return launchList.size();
}
public class RecyclerViewHolder extends RecyclerView.ViewHolder{
public TextView myTextViewName;
public TextView myTextViewDate;
public ImageView myImageViewImage;
public RecyclerViewHolder(#NonNull View itemView) {
super(itemView);
myTextViewName = itemView.findViewById(R.id.launch_name);
myTextViewDate = itemView.findViewById(R.id.date);
myImageViewImage = itemView.findViewById(R.id.thumbnail);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(myListener != null){
int position = getAdapterPosition();
if(position != RecyclerView.NO_POSITION){
myListener.onItemClick(position);
}
}
}
});
}
}
A launch object is just this:
public Launch(String name, String date, String imageUrl) {
this.name = name;
this.date = date;
this.imageUrl = imageUrl;
}
What am I doing wrong?

make getImage function get the index of array object and i will tell you why
String imageUrl = getImageUrl(i);
public String getImageUrl(final int index)
after getting url adding that
String url = rocket.getString("imageURL");
launchesList.get(index).imageUrl = url;
myRecyclerViewAdapter.notifyItemChanged(index);
now i tell the thread of get image get image and when finish notify adapter
it work for me

In your getImageUrl() you are returning the wrong url which is this:
String url = "https://launchlibrary.net/1.3/launch/" + launchId;
instead do this:
public String getImageUrl(){
String url = "https://launchlibrary.net/1.3/launch/" + launchId;
//add this
String imageURL = null;
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("launches");
JSONObject launch = jsonArray.getJSONObject(0);
JSONObject rocket = launch.getJSONObject("rocket");
imageURL = rocket.getString("imageURL");
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
myRequestQueue.add(request);
//return it here
return imageURL;
}

my friend above help u in parsing but let me know why you use two request one for parsing object and second one for get image but u should know that here you will use two thread so we will work on make them in one thread
and check if catch print any log
please send object in array to getImage function and continue to parse
String imageUrl = getImageUrl(launch );
and fix getImageUrl function
public String getImageUrl(JSONObject launch ){
JSONObject rocket = launch.getJSONObject("rocket");
String url = rocket.getString("imageURL");
return url;
}
try this if error still exist please inform me and i will try it on my code

swipe to refresh recyclerview duplicate item json

I have a problem, when i swipe to refresh the data, the first swipe is ok but after that every swipe reload and add the same data over and over again, by the end i have a list with same items over and over...

Just use mExampleList.clear() at the first line of your parseJSON() function
and then you'll be able to add the "updated" items.
In addition I'd suggest that you move swipeRefreshLayout.setRefreshing(false) to the end of Volley onResponse and onError() implementation -
Right now you're telling the swipeRefreshLayout to stop refreshing before the request(that happens asynchronously) has finished

You are initializing your adapter every time you do a swipe.
Change this constructor of MyAdapter code.
public MyAdapter(Context context, ArrayList<one_item> exampleList) {
mContext = context;
mExampleList = exampleList;
}
to,
public MyAdapter(Context context) {
mContext = context;
}
public setExampleList(ArrayList<one_item> exampleList){
mExampleList = exampleList;
}
Now change your onCreate function to.
#SuppressLint("RestrictedApi")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setTitle("APK VIP CHINA");
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
swipeRefreshLayout = findViewById(R.id.refreshlayout);
mRecyclerView = findViewById(R.id.recycler_view);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mExampleList = new ArrayList<>();
mRequestQueue = Volley.newRequestQueue(this);
//Changed Code
mExampleAdapter = new MyAdapter(MainActivity.this);
mRecyclerView.setAdapter(mExampleAdapter);
mExampleAdapter.setOnItemClickListener(MainActivity.this);
parseJSON();
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
parseJSON();
swipeRefreshLayout.setRefreshing(false);
}
});
}
private void parseJSON() {
String url = "http://apkvip.net/json2.php";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject hit = jsonArray.getJSONObject(i);
String creatorName = hit.getString("ten");
String creatorsize = hit.getString("apk_size");
String creatorfile = hit.getString("link_apk");
String imageUrl = hit.getString("link_img");
mExampleList.add(new one_item(imageUrl, creatorName, creatorsize, creatorfile));
}
//Changed Code
mExampleAdapter.setExampleList(mExampleList);
mExampleAdapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override

you are incorrectly parsing JSON from API
Replace
JSONObject jsonObjectthumb = jsonObject1.getJSONObject("thumbnails").getJSONObject("medium");
with
JSONObject jsonObjectthumb = jsonObject1.getJSONObject("snippet").getJSONObject("thumbnails").getJSONObject("medium");
"thumbnails" is inside "snippet" JSONObject

Replace this line
JSONObject jsonObjectthumb = jsonObject1.getJSONObject("thumbnails").getJSONObject("medium");
With
JSONObject jsonObjectthumb = jsonObjectSnippet.getJSONObject("thumbnails").getJSONObject("medium");
The 'thumbnails' object is inside the 'snippet' object.

i try every possible way available on internet but dont get solution.
Anything wrong i am doing?
any idea how to run two recyclerview with above code.
thankx

You can do this-
<android.support.v4.widget.NestedScrollView>
<LinearLayout>
.
.
.
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
This is used to attach 2 or more scrolling views together and one more thing you can do is to make the height of recycler view as "wrap_content".
Hope this helps.

Issue in loading new Images in gridview

I'm making an app that loads the images from server in gridview. I'm using Volley for Http request, glide to download image. I can load the image when app is install and open first time, but when new images are added, it cannot load new images.
URLS
there was 7 urls when app is installed, so it loaded 7 images. but after refresh or reopen app it cannot load 8th image
{"result":[{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/Desert.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/Jellyfish.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/child.png"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/clamber-512.png"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/image:52.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/image:52.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/Temp20181016_051043.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/My Children20182917_022900.jpg"},{"url":"http://smilestechno.000webhostapp.com/ImagesUpload/MyChildren1412414122.jpg"}]}

}
#Override

}
};
}
Even after refresh or reopen app it does not load 8th image.
one more isuue is that it loading image from bottom not from top item.

I found the solution.
The problem was with Volley cache.
stringRequest.setShouldCache(false);
By this we can stop saving cache.

These are my total code related with these problem. Please view the codes and response with some specific solution...

Try this
You made mistake in UserInfo class Constructor.
You added
mExampleList.add(new UserInfo(hsname, image));
But here set id and name
public UserInfo(String id, String name) {
this.id = id;
this.name = name;
}
change your Constructor
public UserInfo(String name, String image_link) {
this.image_link = image_link;
this.name = name;
}
You didn't set any value in image_link variable,But accessing in adapter class
UserInfo info = mExampleList.get(position);
String imageUrl = info.getImage_link();
String hsname = info.getName();

Try this
try {
JSONObject jsonObject = new JSONObject(response);
String logoURL = jsonObject.getString("logo_path")
JSONArray jsonArray = jsonObject.getJSONArray("org_list");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject obj = jsonArray.getJSONObject(i);
String hsname = obj.getString("orga_organame");
String imageurl = obj.getString("orga_image");
String image = logoURL +"/"+ imageurl ;
mExampleList.add(new UserInfo(hsname, image));
}
}
