你如何激活列表活动选中标记？ [英] How do you activate checkmarks in list activity?

问题描述

我有像 arrayAdapter =新的ArrayAdapter＆LT声明数组适配器ListActivity;字符串＆GT; （这一点，android.R.layout.simple_list_item_checked）; 这显示了在最右侧选中标记了一堆行。你能告诉我怎么去一提及这些对号或如何检查/取消选中他们？

I have a ListActivity with an array adapter declared like arrayAdapter = new ArrayAdapter<String> (this, android.R.layout.simple_list_item_checked); This shows a bunch of rows with checkmarks on the far right. Can you tell me how to get a reference to those checkmarks or how to check/uncheck them?

推荐答案

该CheckedTextView本身处理的复选框。它会被传递的第二个参数（查看V）在onListItemClick处理。因此，可以简化您的code如下：

The CheckedTextView itself handles the checkbox. It is passed in as the second argument (View v) in the onListItemClick handler. So, you can simplify your code as follows:

@Override
protected void onListItemClick( ListView l, View v, int position, long id)
{
  CheckedTextView textView = (CheckedTextView)v;
  textView.setChecked(!textView.isChecked());
}
