我是新来的，我是android的新手，我有来自服务器获取数据的国家列表，尝试了所有解决方案，没有任何作用，我需要过滤提取的列表， 我已经应用了这一课 Search through RecyclerView using Searchview
任何解决方案将不胜感激， 提前谢谢。
public class Cities extends AppCompatActivity {
private static RecyclerView.Adapter adapter;
private RecyclerView.LayoutManager layoutManager;
private RecyclerView recyclerView;
private static ArrayList<CitiesModel> cititesNames;
private RecyclerViewUtils.ShowHideToolbarOnScrollingListener showHideToolbarListener;
private EditText mSearchView;
private CitiesAdapter citiesAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cities);
setRecycUp();
getCities();
}
public void setRecycUp() {
mSearchView = (EditText) findViewById(R.id.search_view);
recyclerView = (RecyclerView) findViewById(R.id.city);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setHasFixedSize(true);
}
public void getCities() {
JsonArrayRequest arrayRequest=new JsonArrayRequest(Config.Root+ Config.FITCHCITIES, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
cititesNames=new ArrayList<CitiesModel>();
for(int i=0;i<response.length();i++){
try {
JSONObject jsonObject= (JSONObject) response.get(i);
CitiesModel citiesModel=new CitiesModel();
String CityName = jsonObject.getString("city");
citiesModel.setCity(CityName);
cititesNames.add(citiesModel);
adapter = new CitiesAdapter(Cities.this,cititesNames);
recyclerView.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
if (error instanceof TimeoutError) {
Toast.makeText(getApplicationContext(), "time out Error", Toast.LENGTH_LONG).show();
} else if (error instanceof NoConnectionError) {
Toast.makeText(getApplicationContext(), "no Connection Error", Toast.LENGTH_LONG).show();
} else if (error instanceof AuthFailureError) {
Toast.makeText(getApplicationContext(), "Authenticatin Failure Error", Toast.LENGTH_LONG).show();
} else if (error instanceof NetworkError) {
Toast.makeText(getApplicationContext(), "Network Error", Toast.LENGTH_LONG).show();
} else if (error instanceof ServerError) {
Toast.makeText(getApplicationContext(), "Server Error", Toast.LENGTH_LONG).show();
} else if (error instanceof ParseError) {
Toast.makeText(getApplicationContext(),"JSon Error", Toast.LENGTH_LONG).show();
}
}
})
;
MySingleton.getInstance(getApplicationContext()).addToRequestQueue(arrayRequest);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
return true;
}
}
这是我的适配器
public class CitiesAdapter extends RecyclerView.Adapter<CitiesAdapter.MyViewHolder> {
private List<CitiesModel> dataSet;
private static Context mCtx;
public static class MyViewHolder extends RecyclerView.ViewHolder {
TextView textViewCity;
private Activity mActivity;
public MyViewHolder(View itemView,Activity mActivity) {
super(itemView);
this.textViewCity = (TextView) itemView.findViewById(R.id.cities);
mCtx = itemView.getContext();
this.mActivity=mActivity;
}
}
private Activity mActivity;
public CitiesAdapter(Activity mActivity,List<CitiesModel> data) {
this.dataSet = data;
this.mActivity=mActivity;
}
@Override
public CitiesAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.cities, parent, false);
CitiesAdapter.MyViewHolder myViewHolder = new CitiesAdapter.MyViewHolder(view,mActivity);
return myViewHolder;
}
@Override
public void onBindViewHolder(final CitiesAdapter.MyViewHolder holder, final int listPosition) {
CitiesModel citiesModel = dataSet.get(listPosition);
TextView textViewcity = holder.textViewCity;
textViewcity.setText(citiesModel.getCity().toString().trim());
holder.itemView.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View view) {
mCtx = holder.itemView.getContext();
String prodtype = dataSet.get(listPosition).getCity();
Intent type = new Intent(mCtx, SignUp.class);
type.putExtra("TYPE", prodtype);
mActivity.setResult(0, type);
mActivity.finish();
// Toast.makeText(mCtx,dataSet.get(listPosition).getCity(), Toast.LENGTH_SHORT).show();
}
});
}
@Override
public int getItemCount() {
return (null != dataSet ? dataSet.size() : 0);
}
}
的DataModel
public class CitiesModel {
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
String city;
}
