动态创建表格布局android

Question

我想动态地向表布局中添加行。这是我的代码。

 TableRow tableRow = null;
 TextView textView = null;
 ImageView imageView = null;
 TableLayout tableLayout = (TableLayout)findViewById(R.id.tableLayout);
 RelativeLayout relativeLayout = null;
         for (String string: listOfStrings) {
                            tableRow = new TableRow(this);
                            relativeLayout = (RelativeLayout) View.inflate(this,
                                    R.layout.row, null);
                            textView = (TextView) relativeLayout.getChildAt(0);
                            textView.setText(string);
                            imageView= (ImageView) relativeLayout.getChildAt(1);
                            imageView.setBackgroundColor(R.color.blue);
                            tableRow.addView(relativeLayout);
                            tableLayout.addView(tableRow);
                        }

我已经创建了一个宽度为fill_parent的行布局，textView在最左侧，imageView在最右侧。但是，当我运行这个程序时，行宽显示为wrap_content，而不是带有图像重叠文本的fill_parent。请帮帮忙。谢谢

我注意到的第一件事是在添加视图时没有设置任何LayoutParams。

TableRow tableRow = null;
TextView textView = null;
ImageView imageView = null;
TableLayout tableLayout = (TableLayout)findViewById(R.id.tableLayout);
RelativeLayout relativeLayout = null;

for (String string: listOfStrings)
{
    tableRow = new TableRow(this);
    relativeLayout = (RelativeLayout) View.inflate(this, R.layout.row, null);
    textView = (TextView) relativeLayout.getChildAt(0);
    textView.setText(string);
    imageView= (ImageView) relativeLayout.getChildAt(1);
    imageView.setBackgroundColor(R.color.blue);

    //Here's where I would add the parameters...
    TableLayout.LayoutParams rlParams = new TableLayout.LayoutParams(FILL_PARENT, WRAP_CONTENT);
    tableRow.addView(relativeLayout, rlParams);
    tableLayout.addView(tableRow);
}

在实践中，我还会将行的创建抽象为它们自己的方法。以简化使用/重用。
