Set Text not showing from a function inside a fragment

Set Text not showing from a function inside a fragment - java

I am new in fragments. I am having a fragment which has 3 sides. In my login activity it passes all data by sharedpreference. When I get into my fragment home, it displays the data by the shared preference. In my other part of the fragment is the edit profile. It must retrieve the data I have and put into the set text.
Here is my SideProfileFragment
public class SideProfileFragment extends Fragment{
private static final String TAG = SideProfileFragment.class.getSimpleName();
public EditText name, birthDate, address, occupation, gender, number;
SessionManager sessionManager;
String getId;
private static String URL_READ = "http://isalonbyageeks.000webhostapp.com/readDetail.php";
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_sideprofile, container, false);
return view;
}
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
sessionManager = new SessionManager(getActivity());
sessionManager.checkLogin();
name = (EditText) getActivity().findViewById(R.id.userName);
birthDate = (EditText) getActivity().findViewById(R.id.userBirthDate);
address = (EditText) getActivity().findViewById(R.id.userAddress);
occupation = (EditText) getActivity().findViewById(R.id.userOccupation);
gender = (EditText) getActivity().findViewById(R.id.userGender);
number = (EditText) getActivity().findViewById(R.id.userNumber);
HashMap<String, String> user = sessionManager.getUserDetail();
getId = user.get(sessionManager.ID);
}
private void getUserDetail(){
final ProgressDialog progressDialog = new ProgressDialog(getActivity());
progressDialog.setMessage("Loadingws...");
progressDialog.show();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_READ,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
progressDialog.dismiss();
Log.i(TAG, response);
try {
JSONObject jsonObject = new JSONObject(response);
String success = jsonObject.getString("success");
JSONArray jsonArray = jsonObject.getJSONArray("read");
if(success.equals("1")){
for(int i = 0; 1 < jsonArray.length();i++){
JSONObject object = jsonArray.getJSONObject(i);
String strName = object.getString ("name");
String strNumber = object.getString("phone_number");
String strGender = object.getString("gender");
String strAddress = object.getString("address");
String strOccupation = object.getString("occupation");
String strBirthDate = object.getString("birth_date");
name.setText(strName);
birthDate.setText(strBirthDate);
address.setText(strAddress);
number.setText(strNumber);
gender.setText(strGender);
occupation.setText(strOccupation);
}
}
} catch (JSONException e) {
e.printStackTrace();
progressDialog.dismiss();
Toast.makeText(getActivity(),"Error Reading Detail" +e.toString(), Toast.LENGTH_LONG).show();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Toast.makeText(getActivity(),"Error Reading Detail" +error.toString(), Toast.LENGTH_LONG).show();
}
})
{
#Override
protected Map<String, String> getParams() throws AuthFailureError{
Map<String, String> params = new HashMap<>();
params.put("id", getId);
return super.getParams();
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(stringRequest);
}
#Override
public void onResume(){
super.onResume();
getUserDetail();
}
}
I tried setting the text with a sample "text" inside the oncreated view and it worked. but when I put the set text inside the function getUserDetails it did not do anything, my sideprofile just showed blank edit texts.
PS I tried to put a sample text inside the set text of the function, but still nothing went out.
Edit
This is the XML code of sideprofilefragment that I have. Everything seems so fine!

What should I really need to change? I tried to put
name.setText("sample");
inside the onviewcreated, it worked. but when in the function, it didnt.

Your views will be contained within the view passed in
onViewCreated(View view, #Nullable Bundle savedInstanceState)
and not your activity, so you need to use it to refer your variables.
name = (EditText) view.findViewById(R.id.userName);
change it as above for all views.

Replace all getActivity().findViewById() to view.findViewById()
name = (EditText) view.findViewById(R.id.userName);
replace for all views
also when you receive the result from http request you need to run UI operations on UI thread.
example :
getActivity().runOnUiThread(new Runnable() {
progressDialog.dismiss();
Log.i(TAG, response);
try {
JSONObject jsonObject = new JSONObject(response);
String success = jsonObject.getString("success");
JSONArray jsonArray = jsonObject.getJSONArray("read");
if(success.equals("1")){
for(int i = 0; 1 < jsonArray.length();i++){
JSONObject object = jsonArray.getJSONObject(i);
String strName = object.getString ("name");
String strNumber = object.getString("phone_number");
String strGender = object.getString("gender");
String strAddress = object.getString("address");
String strOccupation = object.getString("occupation");
String strBirthDate = object.getString("birth_date");
name.setText(strName);
birthDate.setText(strBirthDate);
address.setText(strAddress);
number.setText(strNumber);
gender.setText(strGender);
occupation.setText(strOccupation);
}
}
} catch (JSONException e) {
e.printStackTrace();
progressDialog.dismiss();
Toast.makeText(getActivity(),"Error Reading Detail" +e.toString(), Toast.LENGTH_LONG).show();
}
}
});

1) replace all the getActivity().findViewById() by view.findViewById()
2) you need to handle the setting of the UI in another thread
try {
Handler uiHandler = new Handler(Looper.getMainLooper());
uiHandler.post(new Runnable() {
#Override
public void run() {
name.setText(strName);
birthDate.setText(strBirthDate);
address.setText(strAddress);
number.setText(strNumber);
gender.setText(strGender);
occupation.setText(strOccupation);
}
});
} catch (Exception e) {
Log.i("bugs", e.getMessage());
e.printStackTrace();
}
3) If the problem persists, also give android:layout_height="match_parent" to all
the TextViews and EditTexts

how may i resolve ListView Problem ? ERROR: on a null object reference

hello guys i'm back again on a question conserning my final project.
i have made a googlemap app with navigation drawer using activity( no fragment). i think you know about that. then rather than using header and menu, i have use a layout where the header should be so that i can make there a listview to display events all of this is clear.

This is the response:

}
and this is the error:

"id_user_pemilik_kos": 74
} of type org.json.JSONObject cannot be converted to JSONArray
I don't know what is the problem so, what can be done to solve this problem ?

It looks like the service that lives at the requested URL is returning a single JSON object, and not an array of JSON objects.
Try changing your strReq from a JsonArrayRequest to a JsonObjectRequest. That means the onResponse function will accept a JSONObject parameter instead of a JSONArray.
JsonObjectRequest strReq = new JsonObjectRequest(url,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// ...
// Note: you will likely not need this conversion to a JSONObject anymore
// JSONObject jsonObject = new JSONObject(result); <-- Not needed now
}
}
I believe this page will help explain the difference between JsonArrayRequest and JsonObjectRequest.

Change the code like this:
JsonObjectRequest strReq = new JsonObjectRequest(url,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
}
}
You have given that you will get an JsonArray from response. In onResponse() method's body you have used JsonObject. You have mixed up.

anyone can help me whats wrong with my code

You have to place your getText() inside the methode onClick(). Now it's outside and doesn't work.
The line :
"String newJudul = judul_masalah.getText().toString();"
after the line:
"public void onClick(View v){"

here is my arrays.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="incident_type">
<item>Fraud</item>
<item>Malicious Code</item>
<item>Spam</item>
<item>Intrusion</item>
<item>Not Sure</item>
</string-array>
</resources>

the form name is case sensitive.
use $_POST['gender'];
another thing is. where is your definition of $row? looks like it may be empty so you will not post any data.
enable error_reporting and display_errors while development help you to find such kind of errors much faster
another thing very important dont use mysql_* functions they are insecure and deprecated. have a look ad PDO instead
also use prepared statements and escape userinput.

How to show data from DB as a checkbox list in android

I have a DB in mysql, I want to show all the data in the DB as a list of chkbox with the data from the DB . and after selection of few checkbox i can fire query to DB for certain data about the selected ones. I have tried using listView below is my JAVA file and xml

private String jsonResult;
private String url = "http://10.0.2.2/markit/login.php";
private ListView listView;
private TextView textv1;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.bday_select);
listView = (ListView) findViewById(R.id.listView1);
textv1=(TextView)findViewById(R.id.textView1);
accessWebService();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
// Async Task to access the web
private class JsonReadTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(params[0]);
try {
HttpResponse response = httpclient.execute(httppost);
jsonResult = inputStreamToString(
response.getEntity().getContent()).toString();
}
catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
private StringBuilder inputStreamToString(InputStream is) {
String rLine = "";
StringBuilder answer = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
try {
while ((rLine = rd.readLine()) != null) {
answer.append(rLine);
}
}
catch (IOException e) {
// e.printStackTrace();
Toast.makeText(getApplicationContext(),
"Error..." + e.toString(), Toast.LENGTH_LONG).show();
}
return answer;
}
#Override
protected void onPostExecute(String result) {
ListDrwaer();
}
}// end async task
public void accessWebService() {
JsonReadTask task = new JsonReadTask();
// passes values for the urls string array
task.execute(new String[] { url });
}
// build hash set for list view
public void ListDrwaer() {
List<Map<String, String>> employeeList = new ArrayList<Map<String, String>>();
try {
JSONObject jsonResponse = new JSONObject(jsonResult);
JSONArray jsonMainNode = jsonResponse.optJSONArray("emp_info");
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String name = jsonChildNode.getString("emp_name");
String number = jsonChildNode.getString("emp_no");
//String chkBoxNo = Integer.toString(i);
//String chkBoxName = "chk"+chkBoxNo;
//CheckBox chkBoxName = new CheckBox(this);
String outPut = name + "-" + number;
employeeList.add(createEmployee("employees", outPut));
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Error" + e.toString(),
Toast.LENGTH_SHORT).show();
}
SimpleAdapter simpleAdapter = new SimpleAdapter(this, employeeList,
android.R.layout.simple_list_item_1,
new String[] { "employees" }, new int[] { android.R.id.text1 });
listView.setAdapter(simpleAdapter);
}
private HashMap<String, String> createEmployee(String name, String number) {
HashMap<String, String> employeeNameNo = new HashMap<String, String>();
employeeNameNo.put(name, number);
return employeeNameNo;
}
}

The basic concept to create a custom list view in android starts with a custom view .xml that will correspond to the layout of how each individual item will look like. For example if you want each item to have a textview for the name and a checkbox your custom layout will only contain a linear (horizontal) layout with a textview and a check box in. After that on your activity you'll need to create a class that extends Base Adapter. The main roll of this class is to get the data you want (from an array for example) and inflate that info to the layout that you created. I found this tutorial that may help you:

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Set Text not showing from a function inside a fragment - java

Your views will be contained within the view passed in onViewCreated(View view, #Nullable Bundle savedInstanceState) and not your activity, so you need to use it to refer your variables. name = (EditText) view.findViewById(R.id.userName); change it as above for all views.
