snackbar에 대한 arrayadapter 내부보기 전달

Question

arrayadapter에 View 객체를 전달하여 스낵바를 열려고합니다. 뷰를 전달해야하지만, ClickListeners가 작동하지 않기 전에 최종 뷰를 가져와야합니다.

어떻게 내가 매개 변수를 전달하기 위해 별도의 OnMenuItemClickListener을 만들지 않도록 할 PopupMenu.OnMenuItemClickListener 및 DialogInterface.OnClickListener

과거 뷰 변수를 얻을 수 있습니다.

@Override 
public View getView(final int position, View convertView, final ViewGroup parent) { 
case R.id.exercise_options_area: 

try {//setting texts for custom listView 


      deleteArea.setOnClickListener(new View.OnClickListener() {//set to the linear layout 

       @Override 
       public void onClick(View v) { 
final PopupMenu popup = new PopupMenu(parent.getContext(), v); 
popup.getMenu().add(0, 0, 0, menuIconWithText(parent.getResources().getDrawable(R.drawable.ic_rename), "Rename")); 
//if i try using v in snackbar in this line it works, but I don't want it here, I want it down there. using final view = v does not work 

popup.show(); 
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 

    @Override 
    public boolean onMenuItemClick(MenuItem item) { 

     exerciseName = getItem(position);//no spaces, the exerciseName before rename 
     switch (item.getOrder()) { 
      case 0:///////////////////////RENAME 

       AlertDialog.Builder alertBuilder = new AlertDialog.Builder(parent.getContext()); 
       View viewInput = (LayoutInflater.from(parent.getContext())).inflate(R.layout.user_input, null); 
       final EditText inputExerciseName = viewInput.findViewById(R.id.userInput); 

       alertBuilder.setView(viewInput);//show viewInput which is the editText prompt (user_input.xml) 

       alertBuilder.setCancelable(true) 
         .setTitle("Enter New Exercise Name") 
         .setPositiveButton("Save", new DialogInterface.OnClickListener() { 


          @Override 
          public void onClick(DialogInterface dialog, int which) {//on clicking save 
           if (!mainList.contains(inputExerciseName.getText().toString())) { 
            String renamed = inputExerciseName.getText().toString(); 
            renameItem(position, renamed);//rename in the list 



            if (sp.contains(mostRecent + workoutName + " " + exerciseName + " sets")){//only copy if data exists 
             copySharedPreferencesRename(renamed, workoutName, exerciseName,sp,editor);//rename by copying data to new name 
            } 

            checkSharedPreferencesDeleteExercise(workoutName, exerciseName,sp,editor);//delete the data in old name 
            editor.apply();//apply must be done here since this action is separate 
            //refreshListView();//refresh view 



            ((ExerciseList)mContext).recreate();//refresh activity. for past date it refreshes to current 
            if (visitState.equals("pastDate")){ 


            } 
            else 
            *{ 
             simpleSnackBar("Renamed", "#424242", "#FFFFFF", **NEED VIEW HERE**, Snackbar.LENGTH_LONG);//800 grey, white 
             //debug passes this point, but snackbar does not show with final view v 
            }* 
           } 
           else{ 

            return;//make user enter again 
           } 
          } 
         }) 
         .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {//on clicking cancel 
          public void onClick(DialogInterface dialog, int which) { 
           InputMethodManager imm = (InputMethodManager) parent.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);//remove keyboard 
           imm.hideSoftInputFromWindow(inputExerciseName.getWindowToken(), 0); 
           dialog.dismiss(); 
          } 
         }); 

       AlertDialog dialog = alertBuilder.create(); 
       dialog.show(); 
       dialog.setCanceledOnTouchOutside(false); 
       dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE); 

       break; 

Answer 1

당신은이 생성자에서 만들어지는 때 ArrayAdapter에 Activity의 당신의 Fragment 또는 루트의 rootViewViewGroup을 통과해야합니다.

이보기를 ArrayAdapter의 필드로 유지하고 SnackBar을 표시하는 데 사용하십시오.

SnackBar은 아래쪽에 표시 될보기를 원하며, 어댑터의 getView() 메소드의 결과가 아닌 것으로 가정합니다.
