java - Java - TextView 引用 Expendable List View Child 中的另一个 TextView

Question

我有问题。我正在用 Java / Android 编写 List Adapter。我覆盖了返回 View 的方法（它是 Clicked 项目的可消耗列表视图）。问题是：

Log.i 向我展示：

• 05-17 14:04:50.494: I/createTextView(21790): 0 06 Salame
• 05-17 14:04:50.504: I/createTextView(21790): 1 11 Pancetta

但是 TextViews 看起来两者兼而有之：

• 1 11 薄饼
• 1 11 薄饼

看起来 TextView 是指最后一个 TextView。如何解决？

@Override
              public View getGroupView(int groupPosition, boolean isExpanded,
                           View convertView, ViewGroup parent) {
                  Log.e("SecondLevelAdapter", "getGroupView");
                  TextView tv = new TextView(OrderFirstGridPage.this);

                   if((myArrayProductList.get(groupPosition).get(0).getFlgZlozony() == 1)) {

                       Log.i("createTextView", String.valueOf(counterProductName)+" "+myArrayProductList.get(groupPosition).get(counterProductName).toString());
                       tv.setText(myArrayProductList.get(groupPosition).get(counterProductName).toString());
                       counterProductName++;
                           }
                   tv.setPadding(22, 7, 7, 7);
                   tv.setGravity(Gravity.LEFT); 
                   tv.setTextAppearance(OrderFirstGridPage.this, R.style.TextLarge);
                   tv.setTextSize(25);

                     return tv;
              }

我认为使用 LayoutInflater 会更好：

      @Override
  public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
    ViewGroup parent) {

   if (convertView == null) {

    LayoutInflater inf = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   convertView = inf.inflate(R.layout.yourLayout, null);

  }

  TextView tv = (TextView) convertView.findViewById(R.id.yourTextViewId);
   if((myArrayProductList.get(groupPosition).get(0).getFlgZlozony() == 1)) {

                   Log.i("createTextView", String.valueOf(counterProductName)+" "+myArrayProductList.get(groupPosition).get(counterProductName).toString());
                   tv.setText(myArrayProductList.get(groupPosition).get(counterProductName).toString());
                   counterProductName++;
                       }
  tv.setPadding(22, 7, 7, 7);
               tv.setGravity(Gravity.LEFT); 
               tv.setTextAppearance(OrderFirstGridPage.this, R.style.TextLarge);
               tv.setTextSize(25);

 return convertView;
}
