在滚动时将片段添加到活动的末尾

Question

我简化了我的代码，使其更容易理解。我正在从数据库中读取一些数据并在Table Rows中插入。由于有数千个条目，因此加载和冻结UI需要时间。我想要的是在Fragment中移动进程，将SQL查询更改为每次只加载100个条目。我希望每次到达滚动结束时都将此片段添加到活动的末尾。这可以轻松实现吗？

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.order_det_v2);
    TableLayout tl = (TableLayout) findViewById(R.id.prodTable);
    newProductButton = (Button) findViewById(R.id.newProductButton);


    //creates and open the database so we can use it
    dataBase = DataBaseManager.instance();


    Cursor cursor = dataBase.select("SELECT * FROM " + TABLE_NAME_PRODUCTS);
    while (cursor.moveToNext()) {

        int id = cursor.getInt(cursor.getColumnIndex(COLUMN_PRODUCTS_ID));


        TextView textProdCode = new TextView(order_det_v2.this);
        textProdCode.setLayoutParams(new TableRow.LayoutParams(0, 60, 0.08f));
        textProdCode.setBackground(getResources().getDrawable(R.drawable.row_background1));
        textProdCode.setTextColor(Color.BLACK);
        textProdCode.setTextSize(18);

        tr.addView(textProdCode);

        String code = cursor.getString(cursor.getColumnIndex(COLUMN_PRODUCTS_CODE));

        textProdCode.append(" " + code + "\n");


        tr.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(order_det_v2.this, order_det_v2.class);
                intent.putExtra("currentProduct", currentProductID);
                startActivity(intent);
            }
        });
    }
}
