Android studio app crashes on the button click-CodePudding

The

Error Message

The specified child already has a parent. You must call removeView() on the child's parent first.

Solution Tried

Inside add layout function I have done the following

private void addLayout(){ layout2 = LayoutInflater.from(mContext).inflate(R.layout.product_layout, mLinearLayout, false); productAuto = (AutoCompleteTextView) view.findViewById(R.id.tv_product); qtyEditText = (EditText) view.findViewById(R.id.prod_qty); prodPriceEditText = (EditText)view.findViewById(R.id.prod_price); prodSpecsEditText = (EditText)view.findViewById(R.id.prod_specs); }

The product form is shown every time when I click on the Add new Product button. But I can't select a product in this case.

Update 1

I have taken addProduct button in this.initElements(view);

private void initElements(View view) { newSurveyScrollview = (ScrollView) view.findViewById(R.id.new_survey_scrollview); refNofield1 = (EditText) view.findViewById(R.id.ref_no_field_1); consumerNameEditText = (EditText) view.findViewById(R.id.consumer_name); consumerAddressEditText = (EditText) view.findViewById(R.id.consumer_address); latitudeEditText = (EditText) view.findViewById(R.id.latitude); longitudeEditText = (EditText) view.findViewById(R.id.longitude); placeEditText = (EditText) view.findViewById(R.id.place); subDivisionSpinner = (Spinner) view.findViewById(R.id.sub_division_spinner); cameraButton = (Button) view.findViewById(R.id.open_camera); saveButton = (Button) view.findViewById(R.id.save_survey_form); resetButton = (Button) view.findViewById(R.id.survey_reset); getRefNoButton = (Button) view.findViewById(R.id.get_ref_no_button); getLatLangButton = (ImageButton) view.findViewById(R.id.get_lat_lang_button); addProduct = (Button)view.findViewById(R.id.btn_prd); }

The error comes at below part

private void addLayout() { mLinearLayout.addView(layout2); }

Update 2

I have removed the second layout part from onCreatView and done the following

private void addLayout() { layout2 = LayoutInflater.from(mContext).inflate(R.layout.product_layout, mLinearLayout, false); this.initElementsPrd(layout2); mLinearLayout.addView(layout2); }

Below is what I am getting now

The autocomplete is working for the 1st one but for the second or 3rd upto N its not working.

Any help would be highly appreciated.

CodePudding user response：

You are adding a layout by calling this method. But autocomplete textview will not work for the newly added layout because you haven't set the adapter to newly added Layout. You need to call setProd() in addLayout() to bind adapter to autocomplete text view when new layout is added.

private void addLayout(){ layout2 = LayoutInflater.from(mContext).inflate(R.layout.product_layout, mLinearLayout, false); productAuto = (AutoCompleteTextView) view.findViewById(R.id.tv_product); qtyEditText = (EditText) view.findViewById(R.id.prod_qty); prodPriceEditText = (EditText)view.findViewById(R.id.prod_price); prodSpecsEditText = (EditText)view.findViewById(R.id.prod_specs); setProd(); }

Note: For handling dynamic layouts it would be better to handle view object in a list and handle instead of reinstantiating every time to existing object.

Following the Gowtham K K answer I have done the following changes in my code

private void addLayout() { layout2 = LayoutInflater.from(mContext).inflate(R.layout.product_layout, mLinearLayout, false); productAuto = (AutoCompleteTextView) layout2.findViewById(R.id.tv_product); qtyEditText = (EditText) layout2.findViewById(R.id.prod_qty); prodPriceEditText = (EditText)layout2.findViewById(R.id.prod_price); prodSpecsEditText = (EditText)layout2.findViewById(R.id.prod_specs); removeProduct = (Button)layout2.findViewById(R.id.btn_rmv); setProd(); }

Then in my setProd() function

prodArrayList = new ArrayList<String>(); if (isNewSurvey) { prodArrayList.addAll(new ProductManager(getActivity()).getAvailableProducts()); Log.d("Ali", "prod is new booking"); } else { prodArrayList.addAll(new ProductManager(getActivity()).getProducts()); Log.d("Ali", "sub div edit survey"); } prodAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, prodArrayList); productAuto.setAdapter(prodAdapter);

Implementing the above solution my program is working now
