从android中的XML文件中获取特定细节

I am working on a CRM app in android, in which, I am showing details of all contacts in a list view. Now, my requirement is when I click on a particular item in the list, it should only display the details about selected contact, such as, name, address, email, etc.. The data is coming from XML file, which I am parsing using SAX Parser. How can I query a XML to get selected data?

You are filling the ListView using Adapter right? Now you can get the item at the selected view inside the ListView and pass this item to an Activity.

您正在使用适配器填充ListView吗？现在，您可以在ListView内的选定视图中获取该项目，并将此项目传递给活动。

E.g. inside your Adatper class implement the onItemClickListener:

例如。在你的Adatper类中实现onItemClickListener：

public void onItemClick(AdapterView<?> a, View v, int position, long l) {
    // Remembers the selected Index
    Data item =getItem(position);
    Intent intent = new Intent(getApplicationContext(), DetailedActivity.class);
    intent.put("object",item);
    startActivity(intent);
}

Note: the item "Data" class should implement the Parsable interface so it can be passed to the Activity in your DetailedActivity onCreate method get that object and update the UI based on its Values.

注意：项“Data”类应该实现Parsable接口，因此可以将它传递给DetailedActivity onCreate方法中的Activity获取该对象并根据其值更新UI。
