編輯文本不能正常工作的android

Question

你好我試圖做編輯的文字列表視圖，用戶可以輸入他想要的不過我的代碼一直editboxes之間跳躍後，我加入的第一個字符的數字是有沒有辦法制止？我試圖去除焦點並刪除addTextWatcher。但是，當我刪除addtextwatcher non的文本被記錄。請讓我知道，如果你需要更多的信息，因爲這種新的Android類型的生活。這裏是我的適配器代碼： public CreateWKOAdapter（Context context，ArrayList items，ListView listview） inflater = LayoutInflater.from（context）; this.mContext = context; this.items =商品; this.listview = listview; }

@Override 
public int getCount() 
{ 
    return items.size(); 
} 

@Override 
public CreateWKOItem getItem(int position) 
{ 
    return items.get(position); 
} 

@Override 
public long getItemId(int position) 
{ 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) 
{ 
    ViewHolder holder = null; 
    if (convertView == null) 
    { 
     holder = new ViewHolder(); 

     convertView = inflater.inflate(R.layout.create_wko_layout_item, null); 
     holder.name_text_view = (TextView) convertView.findViewById(R.id.text_name); 
     holder.header = convertView.findViewById(R.id.relativeLayout1); 
     holder.input = convertView.findViewById(R.id.oclick_layout); 
     holder.image_view = (ImageView) convertView.findViewById(R.id.foto_createwko); 
     holder.sets_edit_text = (CustomEditText) convertView.findViewById(R.id.sets_edit_text); 
     holder.reps_edit_text = (CustomEditText) convertView.findViewById(R.id.rep_edit_text); 
     holder.checkbox = (ImageView) convertView.findViewById(R.id.image_chk); 

     holder.header.setTag(holder.input); 

     convertView.setTag(holder); 
    } 
    else 
    { 
     holder = (ViewHolder) convertView.getTag(); 

    } 


    if (visibleindex == position) 
    { 
     holder.input.setVisibility(View.VISIBLE); 
     if(holder.sets_edit_text != null) 
     { 
      final EditText clone = holder.sets_edit_text; 
      holder.sets_edit_text.postDelayed(new Runnable() 
      { 
       @Override 
       public void run() 
       { 
        clone.requestFocus(); 
        Log.i("su", "Request focus"); 
       } 
      }, 300); 
     } 
    } 
    else 
    { 
     holder.input.setVisibility(View.GONE); 
    } 

    CreateWKOItem item = getItem(position); 

    if(item.isShouldShowCheckBox()) 
    { 
     holder.checkbox.setVisibility(View.VISIBLE); 
    } 
    else 
    { 
     holder.checkbox.setVisibility(View.GONE); 
    } 
    String image_drawable_str = item.getName().toLowerCase().replace(" ", "_"); 
    Drawable drawable = getImageFromDrawableByString(image_drawable_str); 
    if (drawable != null) 
    { 
     holder.image_view.setImageDrawable(drawable); 
    } 
    else 
    { 
     holder.image_view.setImageResource(R.drawable.bg_count); 
    } 

    holder.sets_edit_text.removeTextWatcher(); 
    holder.reps_edit_text.removeTextWatcher(); 

    holder.name_text_view.setText(item.getName()); 
    holder.sets_edit_text.setHint("" + item.getSets());

Answer 1

我有什麼做的是註釋掉notifyDataSetChanged（）;但只限於設定的代表。

簡單的解決方案：讓你的文本框聽衆，並保留括號爲空。也許它是Android？你可能正在看一個bug。
