我有一個JSON列表視圖是以下內容：從微調選擇項，過濾器/排序從JSON導致的ListView
{
"GetPOIByTypeResult": [
{
"ID": 1,
"Name": "Spitalul Judetean",
"Phone": "085228291",
"Rating": 44,
"Schedule": {
"ClosingHour": 16,
"ID": 1,
"IsNonStop": false,
"IsOpenOnFriday": true,
"IsOpenOnMonday": true,
"IsOpenOnSaturday": false,
"IsOpenOnSunday": false,
"IsOpenOnThursday": true,
"IsOpenOnTuesday": true,
"IsOpenOnWednesday": true,
"Name": "Monday to Friday",
"OpenHour": 8
},
"Specialities": [
{
"ID": 1,
"Name": "Stomatologie"
},
{
"ID": 2,
"Name": "Radiologie"
},
{
"ID": 3,
"Name": "Cardiologie"
},
{
"ID": 4,
"Name": "Ginecologie"
},
{
"ID": 5,
"Name": "Pediatrie"
},
{
"ID": 6,
"Name": "Patologie"
},
{
"ID": 7,
"Name": "Oncologie"
},
{
"ID": 8,
"Name": "Macelarie"
},
{
"ID": 9,
"Name": "Oftalmologie"
},
{
"ID": 10,
"Name": "Ghipsologie"
}
],
"Type": "Hospital"
},
]
}
在我的列表視圖，也有來自外地的結果：「姓名」。 我想過濾列表中沒有顯示在列表中的特殊項目，只返回值。 我反倒不知道如何使這項工作，這是我迄今所做的：
package com.example.medical.map;
import java.util.ArrayList;
public class SearchActivityHospitals extends ListActivity {
Button searchButton;
Button closeButton;
public Spinner spinner1;
private String poiType[];
private boolean isSearch = false;
EditText editText, editText2;
JsonArrayAdapterHospitals adapter;
ArrayList<Hospitals> tempName = new ArrayList<Hospitals>();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_activity_layout_actionbar_hospitals);
adapter = new JsonArrayAdapterHospitals(this, tempName);
setListAdapter(adapter);
poiType = new String[] {"", "Stomatologie", "Radiologie", "Cardiologie", "Ginecologie", "Pediatrie", "Patologie", "Oncologie", "Macelarie", "Oftalmologie", "Ghipsologie"};
//this is my spinner
ArrayAdapter<String> adapter0 = new ArrayAdapter<String>(SearchActivityHospitals.this, android.R.layout.simple_spinner_item, poiType);
adapter0.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
spinner1.findViewById(R.id.spinnerSpecialityHospitals);
spinner1.setAdapter(adapter0);
spinner1.setOnItemSelectedListener(new MyOnItemSelectedListener()
);
WebService.setOnFinishAllHospitals(new OnFinishAllHospitals() {
public void onFinishAllHospitals(ArrayList<Hospitals> hospitals) {
if (hospitals != null) {
if (hospitals.size() > 0) {
tempName.clear();
tempName.addAll(hospitals);
adapter.notifyDataSetChanged();
}
}
}
});
WebService
.GetPOIByType("http://82.77.55.81:9090/MedicalMap/MedicalMap.svc/Getpoibytype/hospital");
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(SearchActivityHospitals.this, DetailsHospitals.class);
intent.putExtra("Value", tempName.get(position));
startActivity(intent);
}
});
editText = (EditText) findViewById(R.id.editNameTextHospitals);
editText.addTextChangedListener(new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s); // Filter from my adapter
adapter.notifyDataSetChanged(); // Update my view
}
public void afterTextChanged(Editable s) {
}
});
editText2 = (EditText) findViewById(R.id.editAddressTextHospitals);
editText2.addTextChangedListener(new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s); // Filter from my adapter
adapter.notifyDataSetChanged(); // Update my view
}
public void afterTextChanged(Editable s) {
}
});
}
//and here is my onitem click listener which I have no idea how to do, please help
public class MyOnItemSelectedListener implements OnItemSelectedListener{
public void onItemSelected(AdapterView<?> parent, View v, int position,
long id) {
if(spinner1.getSelectedItem().equals("Stomatologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Radiologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Cardiologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Ginecologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Pediatrie")){
}else{
}
if(spinner1.getSelectedItem().equals("Patologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Oncologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Macelarie")){
}else{
}
if(spinner1.getSelectedItem().equals("Oftalmologie")){
}else{
}
if(spinner1.getSelectedItem().equals("Ghipsologie")){
}else{
}
}
public void onNothingSelected(AdapterView<?> arg0) {
spinner1.getSelectedItem().equals("");
{
}
}
public void handleClick_search(View v) {
ImageView searchButton = (ImageView) findViewById(R.id.searchButton);
searchButton.setVisibility(View.INVISIBLE);
LinearLayout layout = (LinearLayout) findViewById(R.id.searchFieldLayout);
layout.setVisibility(View.VISIBLE);
}
public void handleClick_closeSearch(View v) {
ImageView searchButton = (ImageView) findViewById(R.id.searchButton);
searchButton.setVisibility(View.VISIBLE);
LinearLayout layout = (LinearLayout) findViewById(R.id.searchFieldLayout);
layout.setVisibility(View.GONE);
}
public void showSearch() {
if (isSearch != true) {
isSearch = true;
searchButton.setVisibility(View.INVISIBLE);
closeButton.setVisibility(View.VISIBLE);
findViewById(R.layout.search_activity_layout_doctors).setVisibility(View.VISIBLE);
}
}
public void hideSearch() {
if (isSearch != false) {
isSearch = false;
searchButton.setVisibility(View.VISIBLE);
closeButton.setVisibility(View.GONE);
findViewById(R.layout.search_activity_layout_doctors).setVisibility(View.GONE);
}
}
}
}
所以我的問題是，如何讓執行以下操作：微調 選擇項目 - >過濾器/排序列表按照選定的標準 標準被解析，但沒有在列表中顯示，所以數據在那裏，但如何做到這一點？
的問題是我是新android開發，也爲Java，所以這將是很好，如果我能看到一個例子代碼:) – SethPDA 2012-07-25 11:54:12
