Please help me to rectify this code.the spinner choice is insert correctly in database but how to show this in textView form?

In Android you can style UI elements as things they are not. For example,
<style name="SpinnerText" parent="android:Widget.TextView"/>
then,
<Spinner style="#style/SpinnerText" .../>
You'll probably have to tweak that to get exactly what you are looking for, but you get the idea.

How to get specific list item and pass the two values from one activity to another?

I am developing an Android app and I in my SecondActivity I have parsed some JSON values as a listview and I want to open up ThirdActivity when a particular list item is clicked and send the values "name" and "number" to the ThirdActivity.
I have tried by creating an Intent in the OnPostExecute method. But am unable to figure out how to pass the values on to the next activity.

Can you try this please
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
Intent intent = new Intent(SecondActivity.this, ThirdActivity.class);
HashMap<String, String> lesson = lessonList.get(i);
intent.putExtra("number", lesson.get("number"));
intent.putExtra("name", lesson.get("name"));
startActivity(intent);
}});

Similar question has been asked before. You have most of it in place, just use Intent.PutStringArrayListExtra and then getIntent.getStringArrayListExtra to pass objects between the activities.
Check this:
Intent.putExtra List

When i click a list item i want to store it name in an edittext

I am creating an eWallet application like many existing ones. I have lots of classes that do different stuff but i need some advice in a group of them. I have created a listview witch fetches the categories i have created and saved in a phpMyAdmin database. I am displaying this data on a list view successfully. This list view just shows the list of the categories to the user and if he clicks a list item a new activity appers which llows him to edit or delete the list item.
Now i used the same code (i lterally used the same code!) to create a second listview inside a dialog box. Imagine that this listview appears inside the dialog box when i click an edit text which has an on click listener. I successfully display the data in this second list view as well. Now on this dialog box when i click a list item/category (lets say Sports category) i want the name of the edit text to change to the category i chose. But i am confused because i use the same code and methods that open the edit and delete activity on my first list view. I hope i did not confuse you too much.
Here is the code that downloads the data in my list views.

follow this code-
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String msupplier=supplier.getSelectedItem().toString();
Log.e("Selected item : ",msupplier);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

I used same answered by sud but with little modification which worked
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// TODO Auto-generated method stub
// String msupplier=supplier.getSelectedItem().toString(); instead used below
Log.e("Selected item : ", (String) parent.getItemAtPosition(pos));
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});

In ListAdapter, getItem() should return an item using which you populate the Views
#Override
public HashMap<String, String> getItem(int paramInt) {
return cartArray.get(paramInt);
}
To get all values,
final CartAdapter adapter = (CardAdapter) lv.getAdapter();
for (int i = 0; i < adapter.getCount(); i++) {
final HashMap<String, String> item = adapter.getItem(i);
final String quantity = item.get(Const.TAG_QUANTITY); // value of EditText of one row
}
