嗨，我必須開發一個微調框架示例。在android中選擇微調框架
列表添加上微調框：
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");
這裏的狀態從以前的活動狀態value.other名單越來越被defaulty Q，P，F，I和C.because第一清單顯示透水狀態only.so只有我必須首先添加狀態here.ahere dd所有值列表包括複製 然後使用for循環檢查當前狀態，並嘗試從列表中刪除。這裏使用這個概念。
這是我的代碼：
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;
private int i;
static final String KEY_NAME = "orderid";
static final String KEY_STATUS = "status";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.change_status);
if (customTitleSupported) {
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
}
final TextView myTitleText = (TextView) findViewById(R.id.mytitle);
if (myTitleText != null) {
myTitleText.setText("Change Order Status");
}
/* Intent in = getIntent();
// Get XML values from previous intent
String orderid = in.getStringExtra(KEY_NAME);
// Displaying all values on the screen
TextView lblName = (TextView) findViewById(R.id.textView1);
lblName.setText(orderid); */
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");
for(i=0;i<((TextView) list).length();i++){
if(list.get(i).equals(status)) {
list.remove(list.get(i));
}
}
//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.
}
}
這裏我的應用程序是力closed.also讓我的控制檯窗口，以下錯誤：

請給我解決這一點。
檢查InsertionExample.java處的行：122 –
我得到了這個解決方案。 – user1676640
