I have a Listview with 3 Textviews, and I want to retrieve the specific data from these textviews on the clicked Item. For now I'm trying to get the data from the first textview. The problem is, it doesn't matter if I click on Item 1, 2, 3 or etc because I'll always get the text from first Item on the listview. I think the problem is because I don't know how to specific which data I want, from which Item. This is my code: estoque.java:

To make it easier for your understanding, this is where I get the clicked item from the listview and try to get it's first textview text(This is on estoque.java):
final ListView lv = (ListView) findViewById(android.R.id.list);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
TextView ttd = (TextView)findViewById(R.id.toptextdata);
System.out.println(ttd.getText().toString());
}
});
Thanks.
Want to access View from clicked row layout of ListView, use second parameter of onItemClick to call findViewById like:
TextView ttd = (TextView) myView.findViewById(R.id.toptextdata);
