格式化新TableRow（以编程方式）

Question

在XML中，我用TableRow（表的标题）定义了TableLayout。每隔一行将以编程方式添加。问题：我无法使新行与XML中的行对齐

>

3个TextView数组，1个TableRow数组

循环使用TextViews和TableRows填充这些数组

全部赋予setTableRowParams方法

设置TextViews的文本

将所有行添加到TableLayout

driversNames = new TextView[DRIVERSAMOUNT];
driversDriven = new TextView[DRIVERSAMOUNT];
driversRemaining = new TextView[DRIVERSAMOUNT];
driversRows = new TableRow[DRIVERSAMOUNT];

for (int i = 0; i < DRIVERSAMOUNT; i++) {

    driversNames[i] = new TextView(this);
    driversDriven[i] = new TextView(this);
    driversRemaining[i] = new TextView(this);

    driversRows[i] = new TableRow(this);
    setTableRowParams(driversRows[i]);

    driversNames[i].setText(driversArray[i].getName());
    driversDriven[i].setText("" + driversArray[i].getTimeDriven());
    driversRemaining[i].setText("" + driversArray[i].getTimeRemaining());



    driversRows[i].addView(driversNames[i]);
    driversRows[i].addView(driversDriven[i]);
    driversRows[i].addView(driversRemaining[i]);

    tableLayout.addView(driversRows[i]);

}

setTableRowParams（）方法

TableLayout.LayoutParams tableRowParams =
        new TableLayout.LayoutParams
                (TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT);
tableRowParams.setMargins(10, 10, 10, 10);

tr.setLayoutParams(tableRowParams);

            <!-- THE VALUES ARE ADDED PROGRAMATICALLY -->

你能告诉我我的错误在哪里吗？

您是否尝试将子视图中的Android:layout_width 属性设置为 ；0dp（当然，将Android:layout_weight 设置为 ；1）？

确保从相同宽度开始的所有子节点(Android:layout_width=“0dp” ）
