Question

我通过以下代码动态添加表格行上的按钮，按钮。

tableLayout = (TableLayout) view.findViewById(R.id.tl);
                Toast.makeText(getActivity(), "option size " + optionList.size(), Toast.LENGTH_SHORT).show();
                while (i < optionList.size()) {

                    tableRow = new TableRow(getActivity());
                    tableLayout.addView(tableRow);

                    option = optionList.get(i);
                    Log.d("TAG", option.getPaymentReason());
                    button = new Button(getActivity());
                    button.setId(option.getId());//set id
                    button.setText(option.getPaymentReason());//set button title
                    button.setBackgroundColor(Color.parseColor(option.getBgColor()));//set btn background
                    button.setTextColor(Color.parseColor(option.getTextColor()));//set text color
                    button.setLayoutParams(params);


                    tableRow.addView(button);

                    i++;
                }

but buttons are not creating.


Log.d("TAG", option.getPaymentReason());

此日志显示正确的输出。我已经使用示例文本（测试）进行了追踪，然后添加了按钮（通过以下代码）

tableLayout = (TableLayout) view.findViewById(R.id.tl);
        Toast.makeText(getActivity(), "option size " + optionList.size(), Toast.LENGTH_SHORT).show();
        while (i < optionList.size()) {
tableRow = new TableRow(getActivity());
            tableLayout.addView(tableRow);

            option = optionList.get(i);
            Log.d("TAG", option.getPaymentReason());
            button = new Button(getActivity());
            button.setId(option.getId());//set id
            button.setText("test");//set button title
            button.setBackgroundColor(Color.parseColor(option.getBgColor()));//set btn background
            button.setTextColor(Color.parseColor(option.getTextColor()));//set text color
            button.setLayoutParams(params);


            tableRow.addView(button);

            i++;
        }

请帮忙

似乎你的布局问题发生了变化

params = new LinearLayout.LayoutParams(  ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

到

TableRow.LayoutParams params = new TableRow.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);

并且工作正常。

动态创建的按钮不显示
