嗨,我需要在 android 中开发一个微调器示例。在这里,我使用了以下代码:
public class InsertionExample extends Activity {
private final String NAMESPACE = "http://xcart.com";
private final String URL = "http://192.168.1.168:8089/XcartLogin/services/update?wsdl";
private final String SOAP_ACTION = "http://xcart.com/insertData";
private final String METHOD_NAME = "insertData";
Button btninsert;
String selectedItem;
static final String KEY_NAME = "orderid";
static final String KEY_STATUS = "status";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.change_status);
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
btninsert = (Button)findViewById(R.id.btn_insert1);
btninsert.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent in = getIntent();
String orderid = in.getStringExtra(KEY_NAME);
String status = in.getStringExtra(KEY_STATUS);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("Status");//Define the variable name in the web service method
unameProp.setValue(selectedItem);//Define value for fname variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);
PropertyInfo idProp =new PropertyInfo();
idProp.setName("Orderid");//Define the variable name in the web service method
idProp.setValue(orderid);//Define value for fname variable
idProp.setType(String.class);//Define the type of the variable
request.addProperty(idProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
TextView result = (TextView) findViewById(R.id.textView2);
result.setText(response.toString());
}
catch(Exception e){
}
}
});
//attach the listener to the spinner
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
//Dynamically generate a spinner data
createSpinnerDropDown();
}
//Add animals into spinner dynamically
private void createSpinnerDropDown() {
//get reference to the spinner from the XML layout
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
//Array list of animals to display in the spinner
List<String> list = new ArrayList<String>();
Intent in = getIntent();
String status = in.getStringExtra(KEY_STATUS);
list.add(status);
list.add("Q");
list.add("P");
list.add("F");
list.add("I");
list.add("C");
//create an ArrayAdaptar from the String Array
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
//set the view for the Drop down list
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//set the ArrayAdapter to the spinner
spinner.setAdapter(adapter);
adapter.notifyDataSetChanged();
//attach the listener to the spinner
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
selectedItem = parent.getItemAtPosition(pos).toString();
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
public void onNothingSelected(AdapterView<?> parent) {
// Do nothing.
}
}
这里List
在微调框上添加了以下内容:
List<String> list = new ArrayList<String>();
Intent in = getIntent();
String status = in.getStringExtra(KEY_STATUS);
list.add(status);
list.add("Q");
list.add("P");
list.add("F");
list.add("I");
list.add("C");
这里的状态是从以前的活动值得到的。其他列表是默认的 Q、P、F、I 和 C。因为第一个列表只显示以前的状态。所以只有我必须先在这里添加状态。
现在我的问题是,
现在我以前的状态是 C 意味着我的微调框必须显示以下格式:
这里第一个和最后一个值仅显示 C。所以 C 值在我的微调框上可用两次。这是我的问题。在这里,我想先添加以前的状态,同时以前的状态没有添加到另一个地方。我怎么能在这里发展。请给我一些解决方案。例如;
如果我之前的状态是 P,那么显示的第一个值是 P,并且还显示 Q、P、F、I、C。所以这里 P 显示了 2 次。那么我该如何解决这个错误。
编辑:
list.add(status);
list.add("Q");
list.add("P");
list.add("F");
list.add("I");
list.add("C");
for(i=0;i<list.length();i++){
if(list.get(i).equals(status)) {
list.remove(list.get(i));
}
}
在这里我得到以下错误: 方法长度()未定义类型列表
我该如何解决这个错误。请帮我
