我正在尝试在我的应用程序中实现autocompletetextview,因为我遵循本教程http://manishkpr.webheavens.com/android-autocompletetextview-example-json/
我有以下回应......
{
"category":
[
{
"id":"4",
"name":"cat1"
},
{
"id":"7",
"name":"aditya"}
]
}
并且这个输出我得到...在'adi'类型后面的输出中它也显示'cat1'..
public class JsonParse {
double current_latitude,current_longitude;
public JsonParse(){}
public JsonParse(double current_latitude,double current_longitude){
this.current_latitude=current_latitude;
this.current_longitude=current_longitude;
}
public List<SuggestGetSet> getParseJsonWCF(String sName)
{
List<SuggestGetSet> ListData = new ArrayList<SuggestGetSet>();
try {
String temp=sName.replace(" ", "%20");
URL js = new URL("http://www.mywebsitename.zookas.in/web-service/categorylist.php?action=category");
URLConnection jc = js.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(jc.getInputStream()));
String line = reader.readLine();
JSONObject jsonResponse = new JSONObject(line);
JSONArray jsonArray = jsonResponse.getJSONArray("category");
for(int i = 0; i < jsonArray.length(); i++){
JSONObject r = jsonArray.getJSONObject(i);
ListData.add(new SuggestGetSet(r.getString("id"),r.getString("name")));
}
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return ListData;
}
}
AdapterFile
public class SuggestionAdapter extends ArrayAdapter<String>{
protected static final String TAG = "SuggestionAdapter";
private List<String> suggestions;
public SuggestionAdapter(Activity context, String nameFilter) {
super(context, android.R.layout.simple_dropdown_item_1line);
suggestions = new ArrayList<String>();
}
@Override
public int getCount() {
return suggestions.size();
}
@Override
public String getItem(int index) {
return suggestions.get(index);
}
@Override
public Filter getFilter() {
Filter myFilter = new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
JsonParse jp=new JsonParse();
if (constraint != null) {
// A class that queries a web API, parses the data and
// returns an ArrayList<GoEuroGetSet>
List<SuggestGetSet> new_suggestions =jp.getParseJsonWCF(constraint.toString());
suggestions.clear();
for (int i=0;i<new_suggestions.size();i++) {
suggestions.add(new_suggestions.get(i).getName());
}
// Now assign the values and count to the FilterResults
// object
filterResults.values = suggestions;
filterResults.count = suggestions.size();
}
return filterResults;
}
@Override
protected void publishResults(CharSequence contraint,
FilterResults results) {
if (results != null && results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
return myFilter;
}
}

答案 0 :(得分:1)
检查这个
for (int i=0;i<new_suggestions.size();i++) {
String name=new_suggestions.get(i).getName();
if(name.contains(constraint)){
suggestions.add(new_suggestions.get(i).getName());
}
}
