這裏是我懷疑當我點擊recyclerview項目需要獲得我保存在sqlite中的任務ID我怎麼能做到這一點，例如當我點擊回收視圖需要將該值傳遞到下一頁，並需要更新該值我該怎麼辦這個到目前爲止我曾嘗試是：如何在點擊recyclerview項目時獲取sqlite的id？
public class Task extends Fragment {
private static final String MY_PREFERENCE_KEY = "yogan";
private List<Model_Task_List> model_task_lists;
private RecyclerView recyclerView;
Task_List_Adapter taskadapter;
private RecyclerView.LayoutManager layoutManager;
SharedPreferences sharedPreferences;
private RecyclerView.Adapter adapter;
RequestQueue yog;
String user_id;
AppController app;
RequestQueue queue;
String Url;
Task_DB task_db = null;
Database_SF_APP database_sf_app;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_task, container, false);
recyclerView = (RecyclerView) view.findViewById(R.id.my_recycler_view);
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setLayoutManager(layoutManager);
if (model_task_lists == null) {
model_task_lists = new ArrayList<Model_Task_List>();
}
Calendar c = Calendar.getInstance();
System.out.println("Current time => " + c.getTime());
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
String formattedDate = df.format(c.getTime());
int hour=c.get(Calendar.HOUR_OF_DAY);
String hours=Integer.toString(hour);
database_sf_app = new Database_SF_APP(getActivity().getBaseContext());
int count=database_sf_app.getTaskCount();
sharedPreferences = getActivity().getSharedPreferences(LoginActivity.login, 0);
user_id = sharedPreferences.getString("user_id", null);
model_task_lists=database_sf_app.getTaskListById(user_id);
taskadapter=new Task_List_Adapter(model_task_lists,getActivity());
recyclerView.setAdapter(taskadapter);
if(taskadapter!=null){
taskadapter.setOnItemClickListener(new Task_List_Adapter.data() {
@Override
public void yog(View v, int position) {
}
});
}
queue = Volley.newRequestQueue(getContext());
Url = "http://xxx.xx.x.xx/xxx/GetActivitiesByUserID.svc/getlist/Task/" + user_id +"/" +null+"/"+hours;
ConnectivityManager cn = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo nf = cn.getActiveNetworkInfo();
if (nf != null && nf.isConnected()) {
Toast.makeText(getActivity(), "Network Available", Toast.LENGTH_LONG).show();
JsonObjectRequest jsonObjRequest = new JsonObjectRequest(Request.Method.POST, Url, new JSONObject(),
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
String server_response = response.toString();
try {
JSONObject json_object = new JSONObject(server_response);
JSONArray json_array = new JSONArray(json_object.getString("TaskResult"));
for (int i = 0; i < json_array.length(); i++) {
Model_Task_List modelobj = new Model_Task_List();
JSONObject json_arrayJSONObject = json_array.getJSONObject(i);
modelobj.setSubject(json_arrayJSONObject.getString("Subject"));
modelobj.setTaskID(json_arrayJSONObject.getInt("TaskID"));
modelobj.setUserName(json_arrayJSONObject.getString("DueDate"));
modelobj.setTaskStatus(json_arrayJSONObject.getString("TaskStatus"));
modelobj.setUserid(json_arrayJSONObject.getString("Owner"));
database_sf_app.insertorUpdate(modelobj);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getContext(), error.toString(), Toast.LENGTH_SHORT).show();
}
});
//Creating request queue
queue.add(jsonObjRequest);
}
//sync operation
//a union b
//a server
//b local storage
//a only - insert local
//b only - send to server
//a = b do nothing
//result
//bind
return view;
}
@Override
public void onResume()
{
super.onResume();
}
@Override
public void onStop() {
super.onStop();
}
}
這裏是我的TaskAdapter：
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.List;
public class Task_List_Adapter extends RecyclerView.Adapter<Task_List_Adapter.MyViewHolder> {
private List<Model_Task_List> dataSet;
private Context context;
private static data yog;
Model_Task_List modelTaskList=new Model_Task_List();
public void remove(int position)
{
dataSet.remove(position);
notifyItemRemoved(position);
}
public void edit(int position){
dataSet.set(position, modelTaskList);
notifyItemChanged(position);
}
public void setOnItemClickListener(data listener) {
this.yog = listener;
}
public static class MyViewHolder extends RecyclerView.ViewHolder {
// Model_Task_List Model_Task_List=new Model_Task_List();
TextView textname;
TextView textaddress;
TextView textphnum;
TextView textdegree;
TextView textemail;
ImageView call;
data datas;
public MyViewHolder(final View itemView) {
super(itemView);
this.textname = (TextView) itemView.findViewById(R.id.subject);
this.textaddress = (TextView) itemView.findViewById(R.id.username);
this.textphnum = (TextView) itemView.findViewById(R.id.status);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(yog!=null){
yog.yog(itemView,getLayoutPosition());
}
}
});
// this.imageViewIcon = (ImageView) itemView.findViewById(R.id.imageView);
}
}
public interface data
{
void yog(View v,int position);
}
public Task_List_Adapter(List<Model_Task_List> data,Context context) {
this.dataSet = data;
this.context=context;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.task_list_view, parent, false);
MyViewHolder myViewHolder = new MyViewHolder(view);
return myViewHolder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
TextView textViewName = holder.textname;
TextView textViewaddress = holder.textaddress;
TextView textViewphnum = holder.textphnum;
TextView textdegree = holder.textdegree;
TextView textemail=holder.textemail;
textViewName.setText("Subject:"+dataSet.get(position).getSubject());
textViewaddress.setText("DueDate"+dataSet.get(position).getUserName());
textViewphnum.setText("Status:"+dataSet.get(position).getTaskStatus());
}
@Override
public int getItemCount() {
return dataSet.size();
}
}
的是它獲得ID正確方法：
taskadapter.setOnItemClickListener(new Task_List_Adapter.data() {
@Override
public void yog(View v, int position) {
Model_Task_List model_task_list=(Model_Task_List)model_task_lists.get(position);
String yog=model_task_list.getSubject().toString();
int yogeshs=model_task_list.getTaskID();
String yogan=Integer.toString(yogeshs);
Toast.makeText(getContext(),yogan,Toast.LENGTH_SHORT).show();
}
});
}
Where i make recyclerview clickable how to get id of sqlite when i click and need to pass the value to next page
你的問題不清楚。請發佈您嘗試的其他內容，而不是您在問題中包含的代碼。 –
檢查我的編輯當我點擊回收視圖需要傳遞值到下一頁與sqlite編號 – Yog
