我使用json加载列表视图，这工作正常。现在我想在此列表中添加一个浮动搜索视图。我不知道如何使用它更正以及如何实现我自己的可搜索功能。你可以帮我一些我。 这是我在主要活动中的代码：
CarDto这是我的连接类：
public class MainActivity extends AppCompatActivity {
private String TAG = MainActivity.class.getSimpleName();
private ProgressDialog pDialog;
private ListView lv;
EditText textView;
Spinner s;
// Search EditText
EditText inputSearch;
FloatingSearchView mSearchView;
// URL to get contacts JSON
// private static String url ="http://10.3.216.241/WorkServIndus.nsf/ListeClient.xsp/ListeClient";
private static String url ="http://myadress/WorkServIndus.nsf/ListeClient.xsp/ListeClient";
ArrayList<HashMap<String, String>> contactList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contactList = new ArrayList<>();
lv = (ListView) findViewById(R.id.list);
// s=(Spinner)findViewById(R.id.spinner);
new GetContacts().execute();
}
/**
* Async task class to get json by making HTTP call
*/
private class GetContacts extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
// Showing progress dialog
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Please wait...");
pDialog.setCancelable(false);
pDialog.show();
}
@Override
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(url);
Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
//JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray contacts = new JSONArray(jsonStr);
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
// return new JSONObject(json.substring(json.indexOf("{"), json.lastIndexOf("}") + 1));
String test=c.getString("ServiFournisseur");
String name = c.getString("universalID");
final String localite=c.getString("Localite");
HashMap<String, String> contact = new HashMap<>();
// adding each child node to HashMap key => value
contact.put("universalID", name);
contact.put("ServiFournisseur", test);
// contact.put("Localite", localite);
// contact.put("ServiFournisseur", lt_name);
// contact.put("location", location);
// adding contact to contact list
contactList.add(contact);
// String lt_name = c.getString("ServiFournisseur");
// String location = c.getString("location");
// return new JSONObject(jsonStr.substring(jsonStr.indexOf("{"), jsonObj.lastIndexOf("}") + 1));
// tmp hash map for single contact
}
} catch (final JSONException e) {
Log.e(TAG, "Json parsing error: " + e.getMessage());
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Json parsing error: " + e.getMessage(),
Toast.LENGTH_LONG)
.show();
}
});
}
} else {
Log.e(TAG, "Couldn't get json from server.");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Couldn't get json from server. Check LogCat for possible errors!",
Toast.LENGTH_LONG)
.show();
}
});
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Dismiss the progress dialog
if (pDialog.isShowing())
pDialog.dismiss();
ListAdapter adapter = new SimpleAdapter(
MainActivity.this, contactList,
R.layout.list_item, new String[]{"universalID","ServiFournisseur"
}, new int[]{R.id.name,R.id.email
});
lv.setAdapter(adapter);
}
}
这是主要布局：
public class HttpHandler
{
private static final String TAG = HttpHandler.class.getSimpleName();
public HttpHandler() {
}
public String makeServiceCall(String reqUrl) {
String response = null;
try {
URL url = new URL(reqUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
// read the response
InputStream in = new BufferedInputStream(conn.getInputStream());
response = convertStreamToString(in);
} catch (MalformedURLException e) {
Log.e(TAG, "MalformedURLException: " + e.getMessage());
} catch (ProtocolException e) {
Log.e(TAG, "ProtocolException: " + e.getMessage());
} catch (IOException e) {
Log.e(TAG, "IOException: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
return response;
}
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line;
try {
while ((line = reader.readLine()) != null) {
sb.append(line).append('\n');
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
list_item.xml：

mSearchView.setOnQueryChangeListener(new FloatingSearchView.OnQueryChangeListener() {
@Override
public void onSearchTextChanged(String oldQuery, final String newQuery) {
//get suggestions based on newQuery
//pass them on to the search view
mSearchView.swapSuggestions(newSuggestions);
}
});
