我正在尝试使用ArrayList<HashMap<String, String>>. 我不明白为什么会出现以下错误：
构造函数SimpleAdapter(Main.getResults, ArrayList<HashMap<String,String>>, int, String[])未定义
public class Main extends Activity {
private static String personURL = "http://api.themoviedb.org/3/search/person?api_key=bb0b6d66c2899aefb4d0863b0d37dc4e&query=";
private static String TAG_CAST = "cast";
private static String TAG_ID = "id";
private static String TAG_TITLE = "title";
String title = null;

JSONArray secondCast = null;

EditText searchTwo;

List<String> searchOneFilmography = new ArrayList<String>();

ArrayList<HashMap<String, String>> commonFilmogrpahy = new ArrayList<HashMap<String, String>>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.totlayout);
searchOne = (EditText) findViewById(R.id.searchOne);
searchTwo = (EditText) findViewById(R.id.searchTwo);
findMovies = (Button) findViewById(R.id.findMovies);

findMovies.setOnClickListener(new View.OnClickListener() {

new getResults().execute();
}
});
}
public class getResults extends AsyncTask<String, Void, ArrayList<HashMap<String, String>> > {

ArrayList<HashMap<String, String>> commonFilms = new ArrayList<HashMap<String, String>>();

String nameOne = searchOne.getText().toString();

for(int i = 0; i < idOne.length(); i++){

firstID = iDeeOne.getString(TAG_ID);
}
for(int i = 0; i < idTwo.length(); i++){

}
String creditURlBase = "http://api.themoviedb.org/3/person";
String firstCreditURL = creditURlBase + firstID;
String secondCreditURL = creditURlBase + secondID;
JSONObject jSon = jParser.getJSONFromUrl(firstCreditURL);
firstCast = jSon.getJSONArray(TAG_CAST);
for(int i = 0; i < firstCast.length(); i++){
JSONObject c = firstCast.getJSONObject(i);
title = c.getString(TAG_TITLE);
//ctreate new hashmap
HashMap<String, String> map = new HashMap<String, String>();
//and node to map
map.put(TAG_TITLE, title);
firstFilms.add(map);
}
JSONObject jSonTwo = jParser.getJSONFromUrl(secondCreditURL);
secondCast = jSonTwo.getJSONArray(TAG_CAST);
for(int i = 0; i < secondCast.length(); i++){
JSONObject c = firstCast.getJSONObject(i);
title = c.getString(TAG_TITLE);
//create hashmap
HashMap<String, String> mapTwo = new HashMap<String, String>();
mapTwo.put(TAG_TITLE, title);
secondFilms.add(mapTwo);
}
if(firstFilms.size() > secondFilms.size()){
for(int i = 0; i < firstFilms.size(); i++){
if(firstFilms.contains(secondFilms.get(i))){
HashMap<String, String> mapThree = new HashMap<String, String>();
mapThree.put(TAG_TITLE, secondFilms.get(i).toString());
commonFilms.add(mapThree);
}
}
}else{
for(int i = 0; i < secondFilms.size(); i++){
if(secondFilms.contains(firstFilms.get(i))){
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_TITLE, firstFilms.get(i).toString());
commonFilms.add(map);
}
}
}
return commonFilms;
}
catch(JSONException e){
Log.e("Error", e.toString());
return null;
}
ListAdapter adapter = new SimpleAdapter(this, commonFilms, R.layout.resultslayout, new String[] {TAG_NAME});
setListAdapter(adapter);
我也试过
ListAdapter adapter = new SimpleAdapter(Main.this, commonFilms, R.layout.resultslayout, new String[] {TAG_NAME});
我仍然只为 Main.this 得到相同的未定义错误。
