Write method to handle on click in a listview android

Question

I am fetching search results from my server and displaying them in a listview. Firstly, I need to change this into a scrollable dropdown. The values in the dropdown are in the format: SchoolA ; Russia I need to capture this text on click and split it into SchoolA and Russia. The code is as follows in activity page:

private void populateResults(String response) {

List<String> resultsFromServer = parseResponse(response);

ListView resultsList = (ListView) findViewById(R.id.schoolssListView);
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, resultsFromServer); 
resultsList.setAdapter(arrayAdapter); 

addListenerOnClick(); // this is the method in which i need the above mentioned operations}

Now, the code in the xml page for listview is as below:

<ListView
    android:id="@+id/schoolssListView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
</ListView>

Answer 1

Try this

listView.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {

   // Your code here , position points to your requirement index

}

});

Onclick you can get the position of the item ,Get the String from the arrayList of that position so you will get Eg: StringA;Russia Then split it with seperator ; and use it

UPDATE

String currentString = "StringA;Russia";

String[] separated = CurrentString.split(";");
separated[0]; // it will contain StringA
separated[1]; // it will contain russia

Alternate

StringTokenizer tokens = new StringTokenizer(CurrentString, ":");

String first = tokens.nextToken();// this will contain "StringA"
String second = tokens.nextToken();
