从Android中的XML文件获取特定的详细信息

Question

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?

Answer 1

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 .

Eg inside your Adatper class implement the 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.
