Question

每个人，实际上我想做的事情与图中显示的相似，
实际上这是我的结帐屏幕的布局，我想动态添加项目，包括＆＃39; +＆＃39;和＆＃39; - ＆＃39;按钮听众，我已经完成了很多堆栈溢出的答案和博客，它们显示了如何动态地向TableLayout添加行，但它们都没有为我工作，我已经使用TableLayout实现了这个结帐屏幕，我发现这只是可以满足的布局我的要求，这是我的checkout_summary.xml布局。

所以，我只是想在这个列表中添加项目（TableLayout）以编程方式，通过保留xml文件中提到的所有布局属性，这是我尝试过的JAVA代码，

 final Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.checout_summary);
    dialog.setCanceledOnTouchOutside(false);
    TableLayout ctbl = (TableLayout) dialog.findViewById(R.id.ctbl);
    int count = 3;
 for (HashMap<String, String> hm: menuList) {
        //hotelList.add(hm);
        TableRow row= new TableRow(this);
        TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,TableRow.LayoutParams.MATCH_PARENT);
        lp.gravity = Gravity.CENTER;
        row.setLayoutParams(lp);

        TextView item = new TextView(this);
        item.setText("item");
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1f);
        params.setMargins(10, 10, 10, 10);
        item.setLayoutParams(params);
        row.addView(item);

        LinearLayout LL = new LinearLayout(this);
        LinearLayout.LayoutParams LLParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1f);
        //LLParams.gravity = Gravity.CENTER;
        LL.setLayoutParams(LLParams);

        Button plus = new Button(this);
        LinearLayout.LayoutParams plul = new LinearLayout.LayoutParams(35, LinearLayout.LayoutParams.WRAP_CONTENT);
        //plul.gravity = Gravity.CENTER;
        plus.setText("+");
        plus.setTextSize(30);
        plus.setTypeface(null,Typeface.BOLD);
        plus.setTextColor(Color.parseColor("#ffff1220"));
        plus.setBackgroundColor(Color.TRANSPARENT);
        plus.setLayoutParams(plul);

        TextView qnty = new TextView(this);
        LinearLayout.LayoutParams qntyl = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        //qntyl.gravity = Gravity.CENTER;
        qntyl.setMargins(10, 0, 10, 0);
        qnty.setLayoutParams(qntyl);

        Button minus = new Button(this);
        LinearLayout.LayoutParams minusl = new LinearLayout.LayoutParams(35, LinearLayout.LayoutParams.WRAP_CONTENT);
        //minusl.gravity = Gravity.CENTER;
        minus.setText("-");
        minus.setTextSize(30);
        minus.setTypeface(null,Typeface.BOLD);
        minus.setTextColor(Color.parseColor("#090"));
        minus.setBackgroundColor(Color.TRANSPARENT);
        minus.setLayoutParams(minusl);

        LL.addView(plus);LL.addView(qnty);LL.addView(minus);
        row.addView(LL);

        TextView disc = new TextView(this);
        disc.setText("4"+" %");
        LinearLayout.LayoutParams discl = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1f);
        discl.setMargins(10, 10, 10, 10);
        disc.setLayoutParams(discl);
        row.addView(disc);

        TextView total = new TextView(this);
        total.setText("Rs. "+"1502");
        LinearLayout.LayoutParams totall = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1f);
        totall.setMargins(10, 10, 10, 10);
        total.setLayoutParams(totall);
        row.addView(total);

        ctbl.addView(row,count);
        count++;
    }

但是，这段代码不断崩溃应用程序，因为我没有在模拟器中运行它，所以我没有这个的logcat！

非常感谢任何帮助。
