获取微调器值取决于另一个微调器的选择

Question

我正在尝试创建一个功能，我可以根据单独的微调器的选择获取微调器值，然后将两个值发布到mysql数据库中，微调器选择工作正常，但它没有发布到数据库，它不是产生任何错误，有人可以告诉我哪里出错了吗？这是我的java。

这是我的字符串

  <resources>

    <string name="app_name">Spinner Example</string>
    <string name="action_settings">Settings</string>
    <string name="lblAcc">Select Account Type</string>
    <string name="lblSubAcc">Select Account Head</string>

  <string-array name="acc_type">
        <item>Eldoret</item>
        <item>Kitale</item>
        <item>Kakamega</item>
        <item>Kisii</item>
        <item>Kericho</item>
    </string-array>

  </resources>

Answer 1

您必须以这种方式获得选定的微调器值：

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

而不是

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

您已使用contentEquals()方法比较字符串。您需要使用equals()或equalsIgnoreCase()来比较字符串。

尝试使用此方法而不是您的方法。

@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>();
