Question

我想在onClick中向tablerow添加滚动视图我已经有了代码但它崩溃了不幸的是，已经停止了

java.lang.IllegalStateException：指定的子节点已经有了家长。您必须首先在孩子的父母上调用removeView（）

我刚刚创建一个GridView，当我点击GridView的项目时，它显示了这个带有行的表格布局，这是我的onClick代码

gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                        long arg3) {
      // TODO Auto-generated method stub
      //Result tr
      String st = "insert into ChecksItems (Check_ID,Item_ID,QTY,UnitPrice,TotalPrice,DicountValue,Tax_Value,Adj_Value,NetPrice,Serial,Fired,Fired_Time,Voided,Voided_Time,Voided_Reason,P_On_Check,Complement,Status,IsModifier,Ref_Mod_Item,IsAssimbly,Ref_Ass_Item,Taxable,NoServiceCharge,Num_Fired,Num_Print,Server_ID,P_On_Report,Check_ID_Combine,Round_Check_Fired,Void_Effect_Invn,Promo_ID,Orig_Price,Officer,Comp_Reason_ID,End_Serial_Count,Discount_ID,Disc_Reason_ID,Hold,Hold_Time,Voided_By,Comp_By,Disc_By) 
                   values (" + String.valueOf(MenuListView.Check_ID) + "," + alphabets.get(arg2).get("Item_ID").toString() + ",1," + alphabets.get(arg2).get("Price").toString() + "," + alphabets.get(arg2).get("Price").toString() + ",0,0,0," + alphabets.get(arg2).get("Price").toString() + "," + String.valueOf(MenuListView.Item_Serial) + ",0,GetDate(),0,GetDate(),0,'" + alphabets.get(arg2).get("PrintOnChick").toString() + "',0,'New',0,0,0,0,'" + alphabets.get(arg2).get("Taxable").toString() + "','" + alphabets.get(arg2).get("NoServiceCharge").toString() + "',0,0,0,'" + alphabets.get(arg2).get("PrintOnReport").toString() + "',0,1,0,0," + alphabets.get(arg2).get("Price").toString() + ",0,0,0,0,0,0,GetDate(),0,0,0)";

      if (ConnectionClass.executeUpdate(st)) {
          MenuListView.Item_Serial++;
          final TableRow tr_head2 = new TableRow(GridDynamic.this);
          tr_head2.setId(10);
          tr_head2.setBackgroundDrawable(getResources().getDrawable(R.drawable.fab_label_background));
          tr_head2.setPadding(10, 10, 10, 10);
          tr_head2.setLayoutParams(new TableLayout.LayoutParams(
                        TableLayout.LayoutParams.FILL_PARENT,

          TextView label_category2 = new TextView(GridDynamic.this);
          label_category2.setId(20);
          label_category2.setText("1");
          label_category2.setTextColor(Color.BLACK);
          label_category2.setTypeface(null, Typeface.BOLD_ITALIC);
          label_category2.setTextSize(18);
          label_category2.setPadding(20, 3, 20, 3);
          tr_head2.addView(label_category2);// add the column to the table row here

          TextView label_quantity_amount2 = new TextView(GridDynamic.this);
          label_quantity_amount2.setId(21);// define id that must be unique
          label_quantity_amount2.setText(alphabets.get(arg2).get("Name").toString()); // set the text for the header
          label_quantity_amount2.setTextColor(Color.BLACK); // set the color
          label_quantity_amount2.setTypeface(null, Typeface.BOLD_ITALIC);
          label_quantity_amount2.setTextSize(18);
          label_quantity_amount2.setPadding(20, 3, 20, 3); // set the padding (if required)
          tr_head2.addView(label_quantity_amount2); // add the column to the table row here

          TextView label_total_price_amount2 = new TextView(GridDynamic.this);
          label_total_price_amount2.setId(22);// define id that must be unique
          label_total_price_amount2.setText(alphabets.get(arg2).get("Price").toString()); // set the text for the header
          label_total_price_amount2.setTextColor(Color.BLACK); // set the color

          label_total_price_amount2.setPadding(20, 3, 20, 3); // set the padding (if required)
          tr_head2.addView(label_total_price_amount2); // add the column to the table row here

          tableLayout.addView(tr_head2, new TableLayout.LayoutParams(

       ScrollView scroll = new ScrollView(GridDynamic.this);
       scroll.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,
                    TableRow.LayoutParams.FILL_PARENT));
       scroll.addView(tr_head2);

编辑：请注意，这个答案是针对此处提出的原始问题（重新删除表格行）....问题已被编辑。

当您向与其关联的表格集标记添加行时

        tableRow.setTag(<some key associated with this row>);
        tableLayout.addView(tableRow);

然后您可以执行以下操作来删除该行。

        View view = tableLayout.findViewWithTag(key);
        if (view != null) {
            tableLayout.removeView(view);
        }
