        mySQLiteAdapter = new AndroidSQLite(this);
        mySQLiteAdapter.openToWrite();
      mySQLiteAdapter.deleteAll();

       mySQLiteAdapter.insert("umesh");
       mySQLiteAdapter.insert("kalpesh");
       mySQLiteAdapter.insert("manish");


        mySQLiteAdapter.close();

        mySQLiteAdapter = new AndroidSQLite(this);
        mySQLiteAdapter.openToRead();

        Cursor cursor = mySQLiteAdapter.queueAll();
        startManagingCursor(cursor);

        String[] from = new String[]{AndroidSQLite.KEY_FNAME};
        int[] to = new int[]{R.id.textView1};




        SimpleCursorAdapter cursorAdapter =
         new SimpleCursorAdapter(this, R.layout.button, cursor, from, to);


                  listContent.setAdapter(cursorAdapter);

Answer 1

I’m not sure If I understand you correctly. As I understood when you click edit you always get the data from the first item regardless of which item you actually clicked? In that case I think the problem is here :

TextView textView=(TextView) findViewById(R.id.textView1);

You’re searching for R.id.textView1 in the whole list and only the first item is being returned. You need to search only within the item clicked :

TextView textView=(TextView) view.findViewById(R.id.textView1);

Where view is the parameter to the onClick function.

As I said I’m not sure if that was the question but it looks like a problem.
