根据另一个微调器的选择获取微调器值

Question

am trying to create a functionality where i can obtain spinner values depending on the selection of a separate spinner and then post both values into a mysql database, the spinner selection is working fine but its not posting to the database, it is not generating any errors either, can someone please tell me where am going wrong? this is my java.

This is my string

  <resources>

    <string name="app_name">Spinner Example</string>
    <string name="action_settings">Settings</string>

    <string name="lblSubAcc">Select Account Head</string>

  <string-array name="acc_type">

        <item>Kakamega</item>
        <item>Kisii</item>
        <item>Kericho</item>
    </string-array>

  </resources>

Answer 1

You have to get Selected spinner value this way:

String sp1= s1.getSelectedItem().toString();

instead of

String sp1= String.valueOf(s1.getSelectedItem());

You have used contentEquals() method for comparing Strings. you need to use equals() or equalsIgnoreCase() for comparing Strings.

Try this method instead of yours.

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) {
    // TODO Auto-generated method stub
    String sp1= s1.getSelectedItem().toString();
    Toast.makeText(this, sp1, Toast.LENGTH_SHORT).show();
    if(sp1.equalsIgnoreCase("Eldoret")) {
        List<String> list = new ArrayList<String>();
        list.add("Tuskys Zion");
        list.add("Tuskys Wareng");
        list.add("Naivas Referral");
        list.add("Ukwala A");
        list.add("Ukwala A");
        list.add("Naivas Sokoni");
        list.add("Uchumi Sugar Land");
        list.add("Uchumi Super");
        list.add("Transmatt");
        list.add("Nakumatt");
        list.add("Khetias");
        list.add("Eldo");
        list.add("Uchumi Sugar Land");
        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, list);`enter code here`
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        dataAdapter.notifyDataSetChanged();
        s2.setAdapter(dataAdapter);
    }
    if(sp1.equalsIgnoreCase("Kitale")) {
        List<String> list = new ArrayList<String>();
        list.add("Suam");
        list.add("Khetias Gigamatt");
        list.add("Khetias Center Point");
        list.add("Khetias Cross Roads");
        list.add("Khetias Euro");
        list.add("Tuskys");

        ArrayAdapter<String> dataAdapter2 = new ArrayAdapter<String>(this,

        ArrayAdapter<String> dataAdapter2 = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, list);

        dataAdapter2.notifyDataSetChanged();
        s2.setAdapter(dataAdapter2);
    }
    if(sp1.equalsIgnoreCase("Kisii")) {
        List<String> list = new ArrayList<String>();

        ArrayAdapter<String> dataAdapter2 = new ArrayAdapter<String>(this,

          dataAdapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        dataAdapter2.notifyDataSetChanged();
        s2.setAdapter(dataAdapter2);
    }

    if(sp1.equalsIgnoreCase("Kericho")) {

        dataAdapter2.notifyDataSetChanged();
        s2.setAdapter(dataAdapter2);
    }


Button btnCreateProduct = (Button) findViewById(R.id.btnCreateProduct);

// button click event
btnCreateProduct.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View view) {
        // creating new product in background thread
        new CreateNewProduct().execute();
    }
});
}

I hope it helps!
