Question

我有一个“ 凯卡马坦 ”变量。
我想将变量（ Kecamatan ）中的值抛出到 jsonParseDesa.java ，但结果始终是< strong> null 。从 AutoCompleteTextView 获取变量。

当我成功显示在日志中时，这里有“ Kecamatan ”变量。可以显示值。代码setAdapter和setOnItemClickListener：

final KecamatanAdapter adapterKecamatan = new KecamatanAdapter(this, autoKecamatan.getText().toString());
    autoKecamatan.setAdapter(adapterKecamatan);
    autoKecamatan.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            // TODO Auto-generated method stub
            JsonParseKecamatan jps=new JsonParseKecamatan();

            Kecamatan selectedSuggestGetSet = adapterKecamatan.getAllUpdatedSuggestion().get(position);
            kecamatan = selectedSuggestGetSet.getId().toString();
            ((JsonParseDesa) XsiswaAddActivity.this.getApplication()).setDistrictId(kecamatan);
            Log.d("Kecamatan Result : ", kecamatan);
        }
    });

代码JsonParseDesa.java：

public class JsonParseDesa extends Application {

double current_latitude,current_longitude;

private String districtId ;

public String getDistrictId() {
    return districtId;
}

public void setDistrictId(String idDistrict) {
    districtId = idDistrict;
}

public JsonParseDesa(){
}
public JsonParseDesa(double current_latitude, double current_longitude){
    this.current_latitude=current_latitude;
    this.current_longitude=current_longitude;
}

public List<Desa> getParseJsonDesa(String sName)
{
    List<Desa> ListData = new ArrayList<Desa>();
    try {
        String temp = sName.replace(" ", "%20");
        URL js = new URL("http://examplewebservice.com/api/public/village/"+districtId+"/"+temp);
        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("desa_kecamatan_rbg");
        for(int i = 0; i < jsonArray.length(); i++){
            JSONObject r = jsonArray.getJSONObject(i);
            ListData.add(new Desa(r.getString("id"),r.getString("district_id"),r.getString("name")));
        }
        Log.d("URL Result : ", js.toString());
    } catch (Exception e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    return ListData;
}
}

为什么字符串districtId为空？代码错误在哪里？谢谢。

AutoCompleteTextView onItemClick AdapterView设置值为null
