嗨，我想Spinner在我的 android 应用程序中创建一个自定义。但我无法开发这个。请帮我。
这是我的 xml 代码：
main.xml
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#ffffffff" >
<TextView
android:id="@+id/textView9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="50dp"
android:layout_y="110dp"
android:text="Status"
android:textSize="20dip"
android:textColor="#1d2328"
/>
<Spinner android:id="@+id/spinner1" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="150dp"
android:layout_y="100dp" android:prompt="@string/status_prompt"
android:background="@drawable/btn_dropdown"
/>
<Button
android:id="@+id/btn_insert1"
android:layout_width="250dp"
android:layout_height="40dp"
android:layout_y="170dp"
android:layout_x="35dp"
android:background="@drawable/lgnbttn"
android:textColor="#FFFFFF"
android:text="Update" />
<TextView
android:id="@+id/textView2"
android:layout_width="280dp"
android:layout_height="43dp"
android:layout_x="20dp"
android:layout_y="255dp"
android:textColor="#465371"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
</AbsoluteLayout>
这是我的java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";

@Override

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");
int position = -1;
for(i=0;i<list.size();i++){
if(list.get(i).equals(status)) {
position = i;
}
}
if(position>0)
list.remove(position);
//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.
}
}
如何在我的应用程序中创建自定义微调器？
