我有一个列表视图，将列出这是在database.I报警需要添加一个切换每个列表项旁边的按钮来设置开启/关闭闹钟。

I have a Listview that will list the alarms which are in the database.I need to add a Toggle Button beside each list item to set the alarm on/off.

我如何添加切换按钮在的ListView ？

R.layout.alarm_list ：

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ListView android:id="@+id/android:list"
      android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
   <TextView android:id="@+id/android:empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/no_reminders"
        android:textColor="#FFF"/>
     </LinearLayout>

Java的code：

Java Code:

      private void fillData() {
    Cursor remindersCursor = aDbHelper.fetchAllAlarms();
    startManagingCursor(remindersCursor);

    // Create an array to specify the fields we want to display in the list
    // (only TITLE)
    String[] from = new String[] { AlarmDbAdapter.KEY_TITLE };

    // and an array of the fields we want to bind those fields to (in this
    // case just text1)
    int[] to = new int[] { R.id.text1};

    // Now create a simple cursor adapter and set it to display
    SimpleCursorAdapter reminders = new SimpleCursorAdapter(this,
            R.layout.alarm_row, remindersCursor, from, to);

    setListAdapter(reminders);
   }

R.layout.alarm_row ：

   <?xml version="1.0" encoding="utf-8"?>

   <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/text1"
    android:padding="10dip" android:layout_width="242dp"  
         android:layout_height="wrap_content"/>

有不小的片段答。您的问题。我认为你需要有多种选择。现在，这里有你需要的东西。

There is no small snippet ans. to your problem. I assume you need to have multi-selection. Now here are the things you need.

由于您使用的 SimpleCursorAdapter ，此时应更换与的CursorAdapter 。要做到这一点，你必须扩展它，因为它是一个抽象适配器。一旦你做了，你将覆盖两个功能。

Since you are using SimpleCursorAdapter, you should replace that with CursorAdapter. To do so you have to extend it as it is a abstract adapter. Once you done that you will be overriding two functions.

NewView的您将创建列表项的看法由充气 R.layout.alarm_row （它应该包含您的切换按钮太）。你必须使开关按钮不点击。 bindView 在这里设置切换按钮和文本的状态，为您的文本视图 newView Where you will create your list item views by inflating R.layout.alarm_row (it should contain your toggle button too). You have make toggle button non-clickable. bindView where you will set state of toggle button and text for your text view

这是说这就是你需要在活动方。

That said this what you need on the Activity side.

您必须通过让你的ListView多选择模式的Andr​​oid：choiceMode XML或使用 setChoiceMode You have make your ListView to multi-selection mode by android:choiceMode in xml or using setChoiceMode.

现在 bindView 将是这样的：

ListView lv = ((ListActivity)context).getListView();
// Containing all check states
SparseBooleanArray sba = lv.getCheckedItemPositions();


// I am using check box

cb.setChecked(false);

// Cursor is passed as an argument.
if(sba != null)
  if(sba.get(cursor.getPosition()))
     cb.setChecked(true);
