推荐答案

如果您想像使用通用 ListView 一样使用点击高亮显示的股票，您希望将每一行的背景设置为 android:background="@android:drawable/list_selector_background"

If you want to use the stock on click highlight like you get with a generic ListView, you want to set the background of each row to be android:background="@android:drawable/list_selector_background"

这是一个例子:

<TableLayout
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:stretchColumns="0">
  <TableRow
     android:id="@+id/first_row"
     android:background="@android:drawable/list_selector_background" >
    ... row content ...
  </TableRow>
</TableLayout>

然后在代码中，

TableRow firstRow = (TableRow) findViewById(R.id.first_row);
firstRow.setOnClickListener(new OnClickListener() {
       @Override
        public void onClick(View v) {
            // TODO: do your logic here

        }   
}

并且您应该像在 ListView 中一样获得一个可突出显示的行...

And you should get a highlight-able row just like in a ListView...

以上将为您提供默认主题的列表背景选择器.如果您想要更通用的选择器(如用户触摸行时的材料设计选择器)，请使用:

Above will give you the default theme's list background selector. If you want the more generic selector (like the material design selector when the user touches a row) use this:

android:background="?android:attr/selectableItemBackground"

这不仅适用于 TableRows.您应该能够在几乎所有附加了 onClickListener 的通用小部件(TextViews、Buttons 等)上执行此操作.

Also this applies to more than just TableRows. You should be able to do this on almost any generic widget with an onClickListener attached (TextViews, Buttons, etc).
