and on selct 1st spinner value i want to display 2nd spinner value.Here is
the code
public class HelloSpinner extends Activity {
public String response;
String[] name = {"","",""};
//String[] name = new String[10];
Spinner spinner1;
@Override
public void onCreate(Bundle savedInstanceState) {
//name[0]="";
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner spinner = (Spinner) findViewById(R.id.spinner);
//spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter =
ArrayAdapter.createFromResource(
this, R.array.planets_array,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
String selectedItem = (String) parent.getSelectedItem();
System.out.println("selectedItem :"+selectedItem);
ArrayList<NameValuePair> postParameters = new
ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("spinner",
selectedItem));
try{
response = CustomHttpClient1.executeHttpPost("
http://10.163.14.75:8083/exist/rest/db/Android/test3.xq";, postParameters);
System.out.println("response :"+response);
parseByDOM(response);
}
catch (Exception e){
e.printStackTrace();
System.out.println("Exception==>"+e.getMessage());
}
spinner1 = (Spinner) findViewById(R.id.spinner1);
// TODO Auto-generated method stub
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
void parseByDOM(String response) {//response is ur xml as string
InputStream is =null;
int i=0;
try {
is = new ByteArrayInputStream(response.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
System.out.println("Encoder exception in getxml:" +
e.getMessage());
}
try {
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(is);
doc.getDocumentElement().normalize();
NodeList nodeLst = doc.getElementsByTagName("name");
int totalPersons = nodeLst.getLength();
System.out.println("totalPersons: " + totalPersons);
for(int k=0;k<totalPersons;k++){
Element firstNameElement = (Element)nodeLst.item(k);
NodeList textFNList = firstNameElement.getChildNodes();
name[i] = ((Node)textFNList.item(0)).getNodeValue().trim();
System.out.println("First Name : " +
((Node)textFNList.item(0)).getNodeValue().trim());
i++;
}
System.out.println("i value :" + i + " "+ name[0]+ " "+
name[1]+ name[2]);
} catch (Exception e) {
System.out.println("Xmlread error :" + e.getMessage());
}
ArrayAdapter<String> adapter1 = new
ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, name);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner1.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
System.out.println("name values :" + name[0] + name[1] +
name[2]);
Toast.makeText(parent.getContext(), "The pm is " +
parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
}
and my strings.xml looks like :
<resources>
<string name="planet_prompt">Choose a planet</string>
<string-array name="planets_array">
<item>Tamilnadu</item>
<item>AndhraPradesh</item>
<item>Karnataka</item>
<item>Kerala</item>
</string-array>
</resources>
and the data received from server is
<cities>
<name stateID="01" cityID="01">Chennai</name>
<name stateID="01" cityID="02">Trichy</name>
<name stateID="01" cityID="03">Madurai</name>
<name stateID="02" cityID="04">Hyderabad</name>
<name stateID="02" cityID="05">Tirupati</name>
<name stateID="03" cityID="06">Bangalore</name>
<name stateID="03" cityID="07">Mangalore</name>
