I am getting the data from server using JSON and when i try to search in the listview it just refreshes the whole list and does not narrate it, but when i debug i can see the result on getfilter is right right and it drugsFiltered = (ArrayList<drugs_json_data>) results.values; does have the filtered data inside it. just the listview.setadaptor is being done inside onPostExecute of the asynctask.
here is my adapter code:
public class drugs_adaptor_listView extends ArrayAdapter<drugs_json_data> implements Filterable {
ArrayList<drugs_json_data> drugs;
ArrayList<drugs_json_data> drugsFiltered;
Context context;
int resource;
public drugs_adaptor_listView(Context context, int resource, ArrayList<drugs_json_data> drugs) {
super(context, resource, drugs);
this.drugs = drugs;
this.drugsFiltered = drugs;
this.context = context;
this.resource = resource;
}

here is the data model:

UPDATED
In getView method in Adapter
Replace
drugs_json_data drugs_json_data = getItem(position);
With
drugs_json_data drugs_json_data = drugsFiltered.get(position);
In my android project i have a listview with items loaded from an online database. When i click on an item i go to another class where i can delete or update it. My problem is that when i press the back button, my listview is empty. I tried onBackPressed with intent to go to previous activity but it is empty again. I want to reload my listview when from a clicked item i press the back button. Below is my code.
The listview:
public class AllStudents extends AppCompatActivity {
ListView StudentListView;
ProgressBar progressBar;
String HttpUrl = "http://sissy-nickels.000webhostapp.com/AllStudentData.php";

// Sending ListView clicked value using intent.
intent.putExtra("ListViewValue", IdList.get(position).toString());
startActivity(intent);
//Finishing current activity after open next activity.
//finish();
}
});
search = (EditText)findViewById(R.id.search);
search.addTextChangedListener(new TextWatcher() {
#Override

Than you in advance!
try this on AllStudents activity
#Override

super.onResume();
if (studentList != null && studentList.size()>0) {
ListAdapter adapter = new ListAdapter(studentList, this);
StudentListView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
*Note
when you make a search you run the filterStudents() method
and replace the current list in the adapter
ListAdapter adapter = new ListAdapter(filteredList, this);
but make sure that if you search for nothing .. return the original list
ListAdapter adapter = new ListAdapter(studentList, this);
or you will get an empty list view
You should not recreate from secondActivity. You just finish it when your work is done in secondActivity. Which means, simply you have to do the below in your secondActivity.

This is my Fragment Class - Here i get the JSON array object and call the adapter class for setting it. In the corressponding XML file, i have used a card view and lsit view to display the data. i want to know how to implement a onItemClickListener{} function so that i can go to another activity and display the list in a more detailed manner.

This is my Adapter class - Where I have gotten the data and set the code
ArrayList<StaffList> myList = new ArrayList<StaffList>();
LayoutInflater inflater;
Context context;
public StaffBaseAdapter(Context context, ArrayList<StaffList> myList) {
this.myList = myList;
this.context = context;
inflater = LayoutInflater.from(this.context);
}
#Override
public int getCount() {
return myList.size();
}
#Override
public StaffList getItem(int position) {
return myList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
MyViewHolder mViewHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.staff_list_view, parent, false);
mViewHolder = new MyViewHolder(convertView);
convertView.setTag(mViewHolder);
} else {
mViewHolder = (MyViewHolder) convertView.getTag();
}
StaffList currentListData = getItem(position);
mViewHolder.tvTitle.setText(currentListData.getTitle());
return convertView;
}
private class MyViewHolder {
TextView tvTitle, tvDesc;
ImageView ivIcon;
public MyViewHolder(View item) {
tvTitle = (TextView) item.findViewById(R.id.tvTitle);
}
}
}
This is my Model Class
String title;
int imgResId;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getImgResId() {
return imgResId;
}
public void setImgResId(int imgResId) {
this.imgResId = imgResId;
}
}
first your model class "staff_model" implement parcelable it will help to transfer your single model item pass to other activity.
Then add ItemClickListener in your listview
add this into your getView function
MyViewHolder rowHolder=new MyViewHolder(convertView);
rowHolder.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//do whatever u want
}
});
listView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Here you can convert your json to string
startActivity(new Intent(this, MainActivity.class).putExtra("myList",new Gson().toJson(list)));
}
});
and in your receiving activity
Type type = new TypeToken<List<String>>() {
}.getType();
List<String> list1=new Gson().fromJson(getIntent().getStringExtra("myList"),type);
Here Specify the TypeToken .You will have the exact json that you passed in the intent.
Hi in the below code I am displaying two spinner one is for displaying brand name and another for displaying model name.
I am getting the response from server like this:
{"RESULT":"SUCCESS","BRANDS":[{"BRANDID":"14","BRANDNAME":"471"},{"BRANDID":"3","BRANDNAME":"ACE"},{"BRANDID":"4","BRANDNAME":"ADLER"},{"BRANDID":"5","BRANDNAME":"ALIEN"},{"BRANDID":"6","BRANDNAME":"ARTISAN-TORO"},{"BRANDID":"7","BRANDNAME":"ASSOCIATED PACIFIC"},{"BRANDID":"8","BRANDNAME":"ASTEX"},{"BRANDID":"9","BRANDNAME":"BERNINA"},{"BRANDID":"10","BRANDNAME":"BONIS"},{"BRANDID":"11","BRANDNAME":"BROTHER"},{"BRANDID":"12","BRANDNAME":"BROTHER "},{"BRANDID":"13","BRANDNAME":"CHANDLER"},{"BRANDID":"15","BRANDNAME":"CINCINNATI"},{"BRANDID":"16","BRANDNAME":"CONSEW"},{"BRANDID":"17","BRANDNAME":"CONSEW\/SEIKO"},{"BRANDID":"18","BRANDNAME":"DENNISON"},{"BRANDID":"19","BRANDNAME":"DURKOPP ADLER"},{"BRANDID":"20","BRANDNAME":"EAGLE"},{"BRANDID":"21","BRANDNAME":"EASTMAN"},{"BRANDID":"22","BRANDNAME":"EASTMAN CARDINAL"},{"BRANDID":"23","BRANDNAME":"ECONOSEW"},{"BRANDID":"1","BRANDNAME":"usha"}]}
Model Response:
{"RESULT":"SUCCESS","MODELS":[{"MODELNAME":"150","MODELID":"2"},{"MODELNAME":"C150WS","MODELID":"3"},{"MODELNAME":"HC720A","MODELID":"4"}
Based on the brand i want to display model names.
