onClick error on passing the data from jsonarray to table view

onClick error on passing the data from jsonarray to table view - java

I'm trying to pass the data from my json array to tableview (its the only one that I found that has an example similar to mine compared to listview) and my app always crashes when I always click my show button and I'm lost because of it.
heres my code :
my code for getting the data from jsonarray:
public class bTSQLClient extends AppCompatActivity {
////for populating the table
private final Context context;
private SimpleTableDataAdapter adapter;
TableView<String[]> tableView;
TableHelper tableHelper;
//getting the current sysID use in protected params
private static final String KEY_SYS_ID = "sys_id";
private int sys_Id = SharedPrefManager.getInstance(this).getUserid();
//View Branch
private static final String KEY_VB_ID = "branchid";
private static final String KEY_VB_USER = "username";
private static final String KEY_VB_PASSWORD = "password";
private static final String KEY_VB_NAME = "branchname";
private static final String KEY_VB_SYSID = "sys_id";
private static final String KEY_VB_CREATED = "created";
private static final String KEY_VB_UT = "user_type";
private int viewBranchID;
private String viewBranchUser;
private String viewBranchPassword;
private String viewBranchName;
private int viewBranchSYSID;
private int viewBranchCreated;
private String viewBranchUT;
//for populating the table
public bTSQLClient(Context context) {
this.context = context;
}
/**
* get Branch Data Operation table populate
*/
public void retrieve(final TableView tableView){
final ArrayList<branchlist> branchList = new ArrayList<>();
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.POST,
Constants.viewbranches_url, null,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
JSONObject jsonObject;
branchlist b;
try
{
for (int i = 0; i < response.length(); i++)
{
jsonObject = response.getJSONObject(i);
//viewBranchID = jsonObject.getInt(KEY_VB_ID);
viewBranchUser = jsonObject.getString(KEY_VB_USER);
//viewBranchPassword = jsonObject.getString(KEY_VB_PASSWORD);
viewBranchName = jsonObject.getString(KEY_VB_NAME);
//viewBranchSYSID = jsonObject.getInt(KEY_VB_SYSID);
//viewBranchCreated = jsonObject.getInt(KEY_VB_CREATED);
//viewBranchUT = jsonObject.getString(KEY_VB_UT);
b = new branchlist();
//b.setBranchid(viewBranchID);
b.setUsername(viewBranchUser);
//b.setPassword(viewBranchPassword);
b.setBranchname(viewBranchName);
//b.setSys_id(viewBranchSYSID);
//b.setCreated(viewBranchCreated);
//b.setUser_type(viewBranchUT);
branchList.add(b);
}
//set to table view
adapter = new SimpleTableDataAdapter(context,new TableHelper(context).returnBranchViewArray(branchList));
tableView.setDataAdapter(adapter);
} catch (JSONException e)
{
//e.printStackTrace();
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
Log.e ( "response", "" + response );
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
Log.e ( "response", "" + error );
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put(KEY_SYS_ID, String.valueOf(sys_Id));
return params;
}
};
RequestHandler.getInstance(this).addToRequestQueue(jsonArrayRequest);
}
}
Heres the TableHelper Class
public class TableHelper {
Context context;
private String[] branchViewHeader = {"Branch Name", "Username"};
private String[][] branchView;
public TableHelper(Context context){
this.context = context;
}
public String[] getBranchViewHeader()
{
return branchViewHeader;
}
public String[][] returnBranchViewArray(ArrayList<branchlist> branchList)
{
branchView = new String[branchList.size()][2];
branchlist b;
for(int i = 0; i<branchList.size();i++){
b = branchList.get(i);
branchView[i][0]=b.getBranchname();
branchView[i][1]=b.getUsername();
}
return branchView;
}
}
branchlist class
public class branchlist {
private int branchid;
private String username;
private String password;
private String branchname;
private int sys_id;
private int created;
private String user_type;
public int getBranchid(){
return branchid;
}
public void setBranchid(int branchid){
this.branchid = branchid;
}
public String getUsername(){
return username;
}
public void setUsername(String username){
this.username = username;
}
public String getPassword(){
return password;
}
public void setPassword(String password){
this.password = password;
}
public String getBranchname(){
return branchname;
}
public void setBranchname(String branchname){
this.branchname = branchname;
}
public int getSys_id(){
return sys_id;
}
public void setSys_id(int sys_id){
this.sys_id = sys_id;
}
public int getCreated(){
return created;
}
public void setCreated(int created){
this.created = created;
}
public String getUser_type(){
return user_type;
}
public void setUser_type(String user_type){
this.user_type = user_type;
}
public String toString(){
return branchname;
}
}
heresmy code for branch(the code that the bTSQLClient will pass to)
public class branch extends AppCompatActivity {
////for populating the table
private SimpleTableDataAdapter adapter;
TableView<String[]> tableView;
TableHelper tableHelper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_branch);
if (!SharedPrefManager.getInstance(this).isLoggedIn()) {
finish();
startActivity(new Intent(this, login.class));
return;
}
//for populating table
tableHelper = new TableHelper(this);
tableView = (TableView<String[]>) findViewById(R.id.tableView);
tableView.setColumnCount(2);
tableView.setHeaderBackgroundColor(Color.parseColor("#2ecc71"));
tableView.setHeaderAdapter(new SimpleTableHeaderAdapter(this,tableHelper.getBranchViewHeader()));
}
/**
* Show populated Table
*/
public void onTableshow(View view){ // The Error is right here (bTSQLClient is the above code)
new bTSQLClient(branch.this).retrieve(tableView);
}
/**
* goto Popup on Add Branch Account
*/
public void onAddBranch(View view){
startActivity(new Intent(branch.this,popup_addbranch.class));
}
/**
* Menu Signout
*/
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.menuLogout:
SharedPrefManager.getInstance(this).isLoggedOut();
finish();
startActivity(new Intent(this, login.class));
break;
}
return true;
}
/**
* Back to dashboard
*/
public void onBack(View view) {
startActivity(new Intent(branch.this, dashboard.class));
}
}
and Heres my postman response for my php code:
[
{
"branchid": 12,
"username": "king",
"password": "202cb962ac59075b964b07152d234b70",

"sys_id": 8,
"created": "2019-10-28 20:45:08",
"user_type": "Branch"
},
{
"branchid": 13,
"username": "makoy",
"password": "bda639c314e39023789c37d7a07469f9",
"branchname": "makoy",
"sys_id": 8,

},
{

"branchname": "foodbranch",
"sys_id": 8,

"user_type": "Branch"
},
{
"branchid": 15,

},
{
"branchid": 16,
"username": "testing101",

"branchname": "rest",
"sys_id": 8,
"created": "2019-11-08 08:28:55",
"user_type": "Branch"
}
]
I think I am finally close to making this problem done since I managed to make the database part show a correct array (the result is the postman result that I posted above)

Android Data Binding not Update UI after retreive data from webservice

I try to implement MVVM by Mindorks to show data from here :(https://api.themoviedb.org/3/movie/384018?api_key=67bc513a7a353631119fdffe5f7377a8&language=en-US) in my Activity. I try using databinding for update UI, but after the data is update, databinding not update my textview. here my Detail Activity Class :
public class DetailActivity extends BaseActivity<ActivityDetailBinding, DetailViewModel> implements DetailNavigator {
#Inject
DetailViewModel detailViewModel;
public static final String INTENT_ID = "id_intent";
public static final String INTENT_FLAG = "id_flag";
private ActivityDetailBinding mActivityDetailBinding;
public static Intent newIntent(Context context) {
return new Intent(context, DetailActivity.class);
}
#Override

}
private void initData(Bundle savedInstanceState) {
Bundle extras = getIntent().getExtras();
if (extras != null) {
int id = extras.getInt(INTENT_ID, 0);
int flag = extras.getInt(INTENT_FLAG, 0);
detailViewModel.fetchDetail(id, flag);
}
}
private void initView() {
if (getSupportActionBar() != null) {
getSupportActionBar().hide();

}
#Override
public void ShowProgressDialog(Boolean loading) {
if (loading) {
showLoading();
} else {

}
}
and my BaseActivity like this :
public abstract class BaseActivity<T extends ViewDataBinding, V extends BaseViewModel> extends AppCompatActivity

// TODO
// this can probably depend on isLoading variable of BaseViewModel,
// since its going to be common for all the activities

I try to show one data first, that is OriginalName for text_title, went I debug my application
public ObservableField<String> getOriginalName() {
return originalName;
}
getOriginalName in class ViewModel, just called before I retrieve my response, but after OriginalName is set, the UI not update and getOriginalName is never called again.I already add originalName.notifyChange(); after the data is set, but it doesn't seem change anything.
I already frustased.. so please... I hope anybody can help me to show me what to do. Thank you very much.

Remove this below line from Detail Activity
setContentView(R.layout.activity_detail);
In your base activity you have performDataBinding method which set the layout id using DataBindingUtil class.
mViewDataBinding = DataBindingUtil.setContentView(this, getLayoutId());
this.mViewModel = mViewModel == null ? getViewModel() : mViewModel;
mViewDataBinding.setVariable(getBindingVariable(), mViewModel);
mViewDataBinding.setLifecycleOwner(this);
mViewDataBinding.executePendingBindings();

Parsing nested JSON with Retrofit library into a RecyclerView: Having a load data error

I'm a newbie in the Android development an am trying to parse complex JSON structure with the help of rertofit library from the http://api.tvmaze.com/search/shows?q=girls. But my project fails in loading data. I suppose that the problem is in the GSON model, but I'm in complete bewilderment what's exactly wrong.
I need to fetch only image and title
I have already included the internet permission in the manifest

I build my model class for fetching image and title, because i need only htese two items:
public class Image:
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Image {
#SerializedName("medium")
#Expose
private String medium;
#SerializedName("original")
#Expose
private String original;
public String getMedium() {
return medium;
}
public void setMedium(String medium) {
this.medium = medium;
}
public String getOriginal() {
return original;
}
public void setOriginal(String original) {
this.original = original;
}
}
public class Movie:
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Movie {
#SerializedName("name")
#Expose
private String name;
#SerializedName("image")
#Expose
private Image image;
public String getTitle() {
return name;
}
public void setTitle(String name) {
this.name = name;
}
public Image getImageUrl() {
return image;
}
public void setImageUrl(Image image) {
this.image = image;
}
}
A recyclerview adapter for those items:
public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MyViewHolder> implements Filterable {
private List<Movie> movieList;
private List<Movie> movieListFiltered;

public void setMovieList(Context context,final List<Movie> movieList){

return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(MovieAdapter.MyViewHolder holder, int position) {
holder.title.setText(movieListFiltered.get(position).getTitle());
GlideApp.with(context).load(movieList.get(position).getImageUrl()).listener(new RequestListener() {
#Override
public boolean onLoadFailed(#Nullable GlideException e, Object model, Target target, boolean isFirstResource) {
// Log the GlideException here (locally or with a remote logging framework):
Log.e(TAG, "Load failed", e);
// You can also log the individual causes:

Log.e(TAG, "Caused by", t);
}
// Or, to log all root causes locally, you can use the built in helper method:
e.logRootCauses(TAG);
return false; // Allow calling onLoadFailed on the Target.
}
#Override
public boolean onResourceReady(Object resource, Object model, Target target, DataSource dataSource, boolean isFirstResource) {
// Log successes here or use DataSource to keep track of cache hits and misses.
return false; // Allow calling onResourceReady on the Target.
}
}).into(holder.image);

Thanks in advance for any help

The fields "name" and "image" that you are trying to parse are nested in a JSON object "show". You need to parse this field as well.
public interface ApiInterface {
#GET("search/shows?q=girls")
Call <List<MovieResponse>> getMovies();
}
Create a new Java object
public class MovieResponse {
#SerializedName("show")
#Expose
private Movie show;
public Movie getShow() {
return show;
}
}

Some items from database not being displayed in cardview

I am having a problem with cardview not displaying some from the database.
My app connects to a grails back end which has a PostgreSQL db.
I have a cardview inside a recyclerview. It receives 7 values in form of JSON but on running the app, only 5 are displayed. I try doing System.out of the JSON in the stack trace and I find that all the 7 values are received so everything is okay on that front.
For clarity purposes, the fields that are not being displayed are labs("labs") and drugs administered("drugsAdministered").
Here is the main class(ClinicalHistory.java), the adapter class, the xml and the stack-trace.

The stack trace
I/System.out: ======================================{"mVisit":[{"id":1,"chiefComplains":"Headache","dateCreated":"2017-08-11T21:00:00Z","labs":"Brucella","hospitalAttended":"Hema Hospital","drugsAdministered":"Tramadol","attendingDoctor":"Dr. Kisinga"

I have found the solution. The problem was in the model.
This was my previous model. Note the parameters in the
setDrugs() and setLabs().
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String hospital) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String hospital) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}
}
After I made this change it worked
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String labs) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String drugs) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}
}

The problem is that, your whole JSON response is a JSONObject if see it carefully.
{
"id_soal": [{
"id_soal": "So0045",
"isi_soal": "Pemilihan Umum tahun 1999 diikuti oleh:",
"bobot_nilai": "1",
"jawab_a": "10 partai politik",
"jawab_b": "18 partai politik",
"jawab_c": "45 partai politik",
"jawab_d": "48 partai politik",
"jawaban_benar": "D"
}, {
"id_soal": "So0039",
"isi_soal": "Prinsup Pembangunan Berkelanjutan adalah :",
"bobot_nilai": "1",
"jawab_a": "Pembangunan terus menerus",
"jawab_b": "Pembangunan yang tidak merusak lingkungan",
"jawab_c": "Pembangunan yang mempertimbangkan kehidupan generasiyang akan datang",
"jawab_d": "Pembangunan yang sesuai rencana pemerintah",
"jawaban_benar": "C"
}, {
"id_soal": "So0065",
"isi_soal": "Dimanakah tempat dibacakan naskah Proklamasi Indonesia ?",
"bobot_nilai": "1",
"jawab_a": "Jl. Diponogoro No. 56",
"jawab_b": "Jl. Pegangsaan timur No. 56",
"jawab_c": "Jl. Teuku Umar No. 67",
"jawab_d": "Jl. Cokroaminoto No. 67",
"jawaban_benar": "B"
}
}
and for Gson to parse your Response Successfully you need to need to Have two model class like below
public class ItemObject {
private List<IdSoal> id_soal = null;
private Integer success;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
public List<IdSoal> getIdSoal() {
return id_soal;
}
public void setIdSoal(List<IdSoal> idSoal) {
this.id_soal = idSoal;
}
public Integer getSuccess() {
return success;
}
public void setSuccess(Integer success) {
this.success = success;
}
}
and,
public class IdSoal {
private String id_soal;
private String isi_soal;
private String bobot_nilai;
private String jawab_a;
private String jawab_b;
private String jawab_c;
private String jawab_d;
private String jawaban_benar;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
public String getId_soal() {
return id_soal;
}
public void setId_soal(String id_soal) {
this.id_soal = id_soal;
}
public String getIsi_soal() {
return isi_soal;
}
public void setIsi_soal(String isi_soal) {
this.isi_soal = isi_soal;
}
public String getBobot_nilai() {
return bobot_nilai;
}
public void setBobot_nilai(String bobot_nilai) {
this.bobot_nilai = bobot_nilai;
}
public String getJawab_a() {
return jawab_a;
}
public void setJawab_a(String jawab_a) {
this.jawab_a = jawab_a;
}
public String getJawab_b() {
return jawab_b;
}
public void setJawab_b(String jawab_b) {
this.jawab_b = jawab_b;
}
public String getJawab_c() {
return jawab_c;
}
public void setJawab_c(String jawab_c) {
this.jawab_c = jawab_c;
}
public String getJawab_d() {
return jawab_d;
}
public void setJawab_d(String jawab_d) {
this.jawab_d = jawab_d;
}
public String getJawaban_benar() {
return jawaban_benar;
}
public void setJawaban_benar(String jawaban_benar) {
this.jawaban_benar = jawaban_benar;
}
}
then all you need to do is like this
ItemObject itemObject = mGson.fromJson(response, ItemObject.class));

You probably need to check your models or the response you are receiving. You are using ItemObject[].class) but might be expecting an object so deserialization is failing.
