Question

我正在尝试使用Niek Haarman的ListViewAnimations库。我正在尝试使用包含xml行的listview的外观动画。 wiki中使用的示例是针对一行TextView，我正在尝试修改它而没有太大成功。

仅仅是文本视图的工作示例中的代码：

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getListView().setDivider(null);

        MyAdapter adapter = new MyAdapter();

        // Create an Animation adapter, wrapping the origional one

        SwingBottomInAnimationAdapter antAdapter = new SwingBottomInAnimationAdapter(adapter);

        // Stack another animation in from the bottom

        SwingRightInAnimationAdapter test2 = new SwingRightInAnimationAdapter(antAdapter);


        test2.setAbsListView(getListView());


        setListAdapter(test2);

        for (int i = 0; i < 50; i++){
            adapter.add("This is row number: " + String.valueOf(i));
        }

    }

    private class MyAdapter extends ArrayAdapter <String>{

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            TextView tv = (TextView) convertView;
            if (tv == null){
                tv = new TextView (MainActivity.this);
            }

            tv.setText(getItem(position));

            return tv;
        }

    }

}

以下是我的代码中的示例，来自fillData方法（我的数据来自内容提供商）：

private void fillData() {

    // Pulls the fields from the database and assigns them to the columns

    String[] from = new String[] { BorrowMeTable.COLUMN_ITEM,
            BorrowMeTable.COLUMN_NAME, BorrowMeTable.COLUMN_DATE, BorrowMeTable.COLUMN_IMAGE };

    // The label for each textview
    int[] to = new int[] { R.id.label, R.id.pName, R.id.pDate, R.id.icon };

    //getLoaderManager().initLoader(0, null, this);
    adapter = new SimpleCursorAdapter(this, R.layout.bm_row, null, from,
            to, 0);

    adapter.setViewBinder(new MyViewBinder()); // Add Viewbinder to allow the BLOB data as a picture

    // ADDED THIS ---- >>>>
    SwingBottomInAnimationAdapter antAdapter = new SwingBottomInAnimationAdapter(adapter);

    // ADDED THIS
    getListView().setAdapter(antAdapter);

    // ADDED THIS ----- >>>>
    setListAdapter(antAdapter);

    getLoaderManager().initLoader(0, null, this);
}

这是我收到的错误消息：

Answer 1

adapter.add（）方法是库中存在的arrayadapter的自定义方法，从库中导入数组适配器（com.haarman.listviewanimations.ArrayAdapter）以使用此方法并确保传递列表您的案例中的元素或空列表到构造函数
