Question

这个问题经常被问到..但似乎没有什么对我有用。

我有一个带有edittext的listview ..当我滚动edittext重复的listview值时。

请建议!!

代码：

public View getView(int position, View view, ViewGroup parent) {

View mView = view;             //trying to reuse a recycled view

    if (mView == null) {
        //The view is not a recycled one: we have to inflate
        mView = getActivity().getLayoutInflater().inflate(
                getResource(), parent, false);
        holder = new ViewHolder();


        holder.row = (OEDataRow) moveLinesfinalData.get(position);

        holder.eProductName = (TextView) mView.findViewById(R.id.textViewProductNameFinal);
        holder.eProductName.setText(holder.row.getString("name").toString());

        holder.innerLinearLayout = (LinearLayout) mView
                .findViewById(R.id.innerLinearLayout);
        holder.editTextProductId = (EditText) holder.innerLinearLayout
                .findViewById(R.id.editTextProductId);
        holder.eProductSerial = (EditText) holder.innerLinearLayout
                .findViewById(R.id.editTextSerialFinal);

        holder.BarCode = (Button) holder.innerLinearLayout.findViewById(R.id.buttonBarcode);
        holder.editTextProductIdFocus = (EditText) holder.innerLinearLayout
                .findViewById(R.id.editTextProductId);

        mView.setTag(holder);
    } else {
        // View recycled !
        // no need to inflate
        // no need to findViews by id
        holder = (ViewHolder) mView.getTag();
    }

    if(holder.row != null) {
        holder.editTextProductId.setText(holder.row.getInt("id").toString());

    }

    holder.eProductSerial.addTextChangedListener(new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
        }
        @Override
        public void afterTextChanged(Editable s) {
            String newSerial = s.toString();

            String id = holder.editTextProductIdFocus.getText().toString();
            productData.put(id,newSerial);

        }
    });

    Log.d("list", "list productData "+productData);

    holder.BarCode.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            v.getId();
        }
    });


    return mView;
}

Answer 1

您必须保存一个字符串数组（类似arrayStrings），其中包含当前位置的EditText值。

在textChangedListener上设置arrayStrings[position]的内容。接下来在getView上将editText的queryText设置为数组中当前位置的任何内容。否则，由于视图将被回收，因此会出现不正确的行为。

Answer 2

而不是

if(holder.row != null) {
    holder.editTextProductId.setText(holder.row.getInt("id").toString());
}

成功

if(holder.row != null) {
      holder.editTextProductId.setText(((OEDataRow) moveLinesfinalData.get(position)).getInt("id"));
}

在HolderView中只保留视图ID，而不保留一些数据本身。

Answer 3

删除：

 holder.row = (OEDataRow) moveLinesfinalData.get(position);

并更改

if(holder.row != null) {
        holder.editTextProductId.setText(holder.row.getInt("id").toString());   
}

到

if((OEDataRow) moveLinesfinalData.get(position) != null) {
        holder.editTextProductId.setText(String.valueOf((OEDataRow) moveLinesfinalData.get(position)).getInt("id"))); 
}

带有edittext的listview重复滚动的值
