My questions is, how do I pass the list data i have obtained from JSON in a fragment to an activity?

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

mViewHolder = new MyViewHolder(convertView);
convertView.setTag(mViewHolder);

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.

how to show only selected data when spinner value is selected in android?

I have got 3 spinner where data is coming from server, if we click the search button without selecting any spinner then on next activity , it should show all list(all product without condition), but if we select according to 3 spinner then it should show only related item.I am getting all item when clicking search button without selecting anything but i am not getting selected item in next activity .

In Pigeon listing activity there is 1 option like search activity where user can search without selecting any item just like in search activity.

Set listeners for each of your spinners
setOnItemSelectedListener
In onItemSelected method , get the selected value in a variable and pass on these values to next activity.
E.g.
yourSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String yourValue = yourSpinner.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
