list view change item randomly

I have a listview that when I change the value of one item (count) with click on plus button, Everything is fine as long as the user do scroll down and show more items
And we see that on each page of the scroll has changed a value of item!!!
idont kNow why everything seems fine!!

Remove notifyDataSetChanged from if-else conditions, May this will work
public void filter(String s, ImageView img) {
HashMap<String, Object> wp = new HashMap<>();
if (!s.equals("")) {
fdata.clear();
for (int i = 0 ;i<data.size();i++) {
wp = data.get(i);
if (wp.get("name").toString().toLowerCase().contains(s)) {
fdata.add(wp);
//notifyDataSetChanged();
}
}
}
else {
fdata = new ArrayList<>(selecteddata);
//notifyDataSetChanged();
}
notifyDataSetChanged();
}

you can use NestedScrollview outside the listview and stop the scrolling of listview by using this: smoothScrollBy(0, 0);

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.

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;
}
}

Android: Hide DatePicker header (selected day, month and year)

I was trying to create a CalendarView in Lollipop when I ran it I didn't get the same design as Marshmallow so I changed to DatePicker but I don't want the header part just the Calendar. Is that possible?
I have tried this code in my MainActivity but with no luck (referring to this link
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initMonthPicker();
}
public void initMonthPicker() {
DatePicker dp_mes = (DatePicker) findViewById(R.id.datePicker2);
int year = dp_mes.getYear();
int month = dp_mes.getMonth();
int day = dp_mes.getDayOfMonth();
dp_mes.init(year, month, day, new DatePicker.OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
int month_i = monthOfYear + 1;
Log.e("selected month:", Integer.toString(month_i));
//Add whatever you need to handle Date changes
}
});
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int daySpinnerId = Resources.getSystem().getIdentifier("day", "id", "android");
if (daySpinnerId != 0) {
View daySpinner = dp_mes.findViewById(daySpinnerId);
if (daySpinner != null) {
daySpinner.setVisibility(View.GONE);
}
}
int monthSpinnerId = Resources.getSystem().getIdentifier("month", "id", "android");
if (monthSpinnerId != 0) {
View monthSpinner = dp_mes.findViewById(monthSpinnerId);
if (monthSpinner != null) {
monthSpinner.setVisibility(View.VISIBLE);
}
}
int yearSpinnerId = Resources.getSystem().getIdentifier("year", "id", "android");
if (yearSpinnerId != 0) {
View yearSpinner = dp_mes.findViewById(yearSpinnerId);
if (yearSpinner != null) {
yearSpinner.setVisibility(View.GONE);
}
}
} else { //Older SDK versions
Field f[] = dp_mes.getClass().getDeclaredFields();
for (Field field : f) {
if (field.getName().equals("mDayPicker") || field.getName().equals("mDaySpinner")) {
field.setAccessible(true);
Object dayPicker = null;
try {
dayPicker = field.get(dp_mes);
} catch (IllegalAccessException e) {
e.printStackTrace();
}
((View) dayPicker).setVisibility(View.GONE);
}
if (field.getName().equals("mMonthPicker") || field.getName().equals("mMonthSpinner")) {
field.setAccessible(true);
Object monthPicker = null;
try {
monthPicker = field.get(dp_mes);
} catch (IllegalAccessException e) {
e.printStackTrace();
}
((View) monthPicker).setVisibility(View.VISIBLE);
}
if (field.getName().equals("mYearPicker") || field.getName().equals("mYearSpinner")) {
field.setAccessible(true);
Object yearPicker = null;
try {
yearPicker = field.get(dp_mes);
} catch (IllegalAccessException e) {
e.printStackTrace();
}
((View) yearPicker).setVisibility(View.GONE);
}
}
}
}
}

Is there anything I am doing wrong?

Android Custom BaseAdapter getView not called

So, I have scoured the interwebs and I cannot find a solution for this based on other people's experiences, so I am posting this issue. (Please note that this is my 1st android app experience and I am debugging / updating an existing app.)
When I implement my custom NotesListAdapter (extends BaseAdapter) on the ListView, mListNotesView (mListNotesView.setAdapter(this)), and load the data into the ArrayList mNoteList, the getView function is not being called. Also, I found that mListNotesView.setBackgroundResource is not chaning the background of the control, either. I have a similar implementation on a previous activity that works exactly correct. When I copied over the class and changed it to handle my ArrayList, it broke. I have getCount returning the ArrayList size(), which is not 0, and getItemId returns position. I have a feeling it may be my XML or my setup because it's acting like the ListView is not visible. I am perplexed. How do I get the ListView to show? Anything inside of the getView has not been reached so it may be buggy.

I'm going to recommend you reorganize your code. Here are some general tips:
1) Keep your views like ListView in the Activity class. Don't try to inflate the view in your adapter class. So in your activity's onCreate() after setContentView() you should have something like:
ListView listView = (ListView) findViewById(R.id.listView);
2) Next you need to get the data that will be shown in the listview and store it in a list. I didn't see in your code where the data comes from, but let's just say it comes from a database. You should create something like an ArrayList and store the data that you want to show in the ListView in the ArrayList
3) Next you need to create an adapter and pass the list of data into the adapter.
4) Once this has been done the ListView now has an adapter that will supply data to it. If you've done everything correctly then the system will eventually call getView() automatically and your code inside that should run and render the view.
Not an exact solution, but hopefully this explanation will help you figure it out.

Delete interface open camera on Android studio

I really need help here. I have project which call MyHeartRate, I downloaded the source code of heart rate project at Github. So I try to run that source code and there is no error. In the interface layout, it display the "camera". Example, when you open your camera then you will see the screen focus on what area that you want to take the picture. So my problem is, I want to remove that "camera" in my layout. I need to know which code need to be delete so then the "camera" not in my layout.
here's my code

tq,

I found the answer. just comment this code
//preview = (SurfaceView) findViewById(R.id.preview);
//previewHolder = preview.getHolder();
//previewHolder.addCallback(surfaceCallback);
//previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
done.
