如果您想像使用通用 ListView 一样使用单击突出显示的库存,则需要将每行的背景设置为 android:background="@android:drawable/list_selector_background"

这里是一个例子:

<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

        }   
}

你应该得到一个可突出显示的行,就像在 ListView 中一样...

编辑:
上面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(例如用户触摸行时的材料设计选择器),请使用此:

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

此外,这不仅适用于 TableRows。您应该能够在几乎任何带有 onClickListener 的通用小部件(文本视图、按钮等)上执行此操作。

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"

Here is an example:

<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>

Then in code,

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

        }   
}

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

EDIT:
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"

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).

即使我在 salil pandit 答案的帮助下也面临着同样的问题,但对其做了一些更改,这对我有用

这是 xml 中的 TableRow

<TableRow
        android:id="@+id/tableRow1"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:padding="5dip" 
        android:background="@drawable/selector">

这是 selector.xmlres\drawable 文件夹中

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item   android:state_focused="true"
            android:state_pressed="true"
            android:drawable="@android:drawable/list_selector_background"></item>
    <item   android:state_focused="true"
            android:state_pressed="false"
            android:drawable="@android:drawable/list_selector_background"></item>
    <item
            android:state_focused="false"
            android:state_pressed="true"
            android:drawable="@android:drawable/list_selector_background" />


     <item android:drawable="@android:drawable/list_selector_background"></item>

</selector>

Even I was facing the same problem with the help of salil pandit answer made a little change to it and that works for me

This is TableRow in xml:

<TableRow
        android:id="@+id/tableRow1"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:padding="5dip" 
        android:background="@drawable/selector">

This is selector.xml in res\drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item   android:state_focused="true"
            android:state_pressed="true"
            android:drawable="@android:drawable/list_selector_background"></item>
    <item   android:state_focused="true"
            android:state_pressed="false"
            android:drawable="@android:drawable/list_selector_background"></item>
    <item
            android:state_focused="false"
            android:state_pressed="true"
            android:drawable="@android:drawable/list_selector_background" />


     <item android:drawable="@android:drawable/list_selector_background"></item>

</selector>

在 onclicklistener 中添加:

 tr1.setBackgroundResource(drawable.list_selector_background);

其中 tr1 是您的表格行。 (您需要将表格行最终确定才能工作)。

Within the onclicklistener add:

 tr1.setBackgroundResource(drawable.list_selector_background);

Where tr1 is your tablerow. (you will need to make the tablerow final for it to work).

@SalilPandit 的带有行选择器的编程版本:

final TableRow row = new TableRow(this);

row.setBackgroundResource(android.R.drawable.list_selector_background);

row.setOnClickListener(new View.OnClickListener(){            

     @Override
     public void onClick(View view){
         row.setFocusable(true);
         // TODO
     }
});

对于通用选择器(材料设计):

TypedValue typeValue = new TypedValue();
this.getTheme().resolveAttribute(android.R.attr.selectableItemBackground,
                                 typeValue, true);

final TableRow row = new TableRow(this);
row.setBackgroundResource(typeValue.resourceId);

row.setOnClickListener(new View.OnClickListener(){

    @Override
    public void onClick(View view){
          row.setFocusable(true);
          // TODO
    }
});

@SalilPandit 's programmitical version with row selector:

final TableRow row = new TableRow(this);

row.setBackgroundResource(android.R.drawable.list_selector_background);

row.setOnClickListener(new View.OnClickListener(){            

     @Override
     public void onClick(View view){
         row.setFocusable(true);
         // TODO
     }
});

For generic selector ( material design ):

TypedValue typeValue = new TypedValue();
this.getTheme().resolveAttribute(android.R.attr.selectableItemBackground,
                                 typeValue, true);

final TableRow row = new TableRow(this);
row.setBackgroundResource(typeValue.resourceId);

row.setOnClickListener(new View.OnClickListener(){

    @Override
    public void onClick(View view){
          row.setFocusable(true);
          // TODO
    }
});
