Get value of item on OnItemClick Listview

Question

I try to get the value of a selected Item within a custom adapter on a listview. I try this with following code:

public void onItemClick(AdapterView<?> parent, View v,
                        int position, long id) {

                    View curr = parent.getChildAt((int) id);
                    TextView c = (TextView)curr.findViewById(R.id.tvPopUpItem);
                    String playerChanged = c.getText().toString();

                    Toast.makeText(Settings.this,playerChanged, Toast.LENGTH_SHORT).show();

                }

At the beginning, if I click, the values are good, but once I scrolled and I click on another Item, I get the wrong value of that clicked item... Any idea what is causing this?

Answer 1

The parameter v is the current row. so use:

public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
    TextView c = (TextView) v.findViewById(R.id.tvPopUpItem);
    String playerChanged = c.getText().toString();

    Toast.makeText(Settings.this,playerChanged, Toast.LENGTH_SHORT).show();
}

(Or you could use getChildAt(position) but this would be slower.)

Understand you might be able to simplify this more depending on your layout.

Answer 2

Just Small Change is Required

TextView c = (TextView) v.findViewById(R.id.tvPopUpItem);

Since you are using custom view you need to pass the View argument in your OnItemClickListener then you need to use that value to get the Details of TextViews present in that

Answer 3

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Intent i=new Intent(ListOfAstrologers.this,AstroProForUser.class);
                i.putExtra("hello",adapter.getItem(position).getUsername() );
                startActivity(i);
            }
        });

Here username is a string field declared in a class and you must over ride getItem() method in adapter class to get the details of inflated row when you click.
