實現效果:
效果就是這樣,我們要實現這樣的效果,其實思路就是:
1、我們要記錄下按鈕的狀態,同時儲存文字框。
2、主要是在BaseAdapter中進行監聽。
class MyAdapter extends BaseAdapter{ private Map<Integer,Integer> mapToggle; //用於儲存Toggle的狀態 private Map<Integer,String> mapReason; //用於儲存文字框的內容 public MyAdapter(){ mapToggle = new HashMap<Integer,Integer>(); mapReason = new HashMap<Integer,String>(); } @Override public int getCount() { return 30; } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { convertView = LayoutInflater.from(_this).inflate(R.layout.activity_price_item, null); TextView tv_title = (TextView) convertView.findViewById(R.id.price_item_title); TextView tv_price = (TextView) convertView.findViewById(R.id.price_item_price); final EditText et_text = (EditText) convertView.findViewById(R.id.price_item_reason); ToggleButton toggleButton = (ToggleButton) convertView.findViewById(R.id.price_item_toggle); final LinearLayout linear= (LinearLayout) convertView.findViewById(R.id.price_relative); tv_title.setText("測試用例" + position); linear.setTag(position); et_text.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) {//記錄文字框的內容 int index = (Integer) linear.getTag(); mapReason.put(index, s.toString()); } }); toggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener(){ @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if(isChecked){ int index = (Integer) linear.getTag(); mapToggle.put(index, 0); linear.setVisibility(View.GONE); }else{ int index = (Integer) linear.getTag(); mapToggle.put(index, 1); linear.setVisibility(View.VISIBLE); } } }); if(mapToggle != null){//重新恢復狀態 int index = (Integer) linear.getTag(); if(!mapToggle.keySet().isEmpty() && mapToggle.containsKey(index) && mapToggle.get(index) == 1){ if(toggleButton.isChecked()) toggleButton.setChecked(false); }else{ toggleButton.setChecked(true); } if(!mapReason.keySet().isEmpty()) et_text.setText(mapReason.get(index)); } return convertView; } }
