安卓：BaseAdapter如何？ [英] Android : BaseAdapter how to?

问题描述

好吧，我一直在寻找厚，薄，我有一些问题，实施BaseAdapter。

Ok, I have been searching thick and thin, and I am having some issues implementing a BaseAdapter.

我已经能够实现一个简单的游标适配器 <一href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List7.html" rel="nofollow">http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List7.html根据上面的例子

I have been able to implement a Simple Cursor Adapter http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List7.html as per the example above.

有一个pretty的很好的BaseAdapter这里例如：<一href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html"相对=nofollow> List14谷歌的例子

There is a pretty good BaseAdapter example here : List14 google example

我想使用BaseAdapter显示一个ListView创建自己的表适配器，与数据库中的多个项目。我知道这可以通过使用简单的游标适配器来完成，但我期待以不同方式处理行，所以我希望能够通过覆盖getView绘制每一行。该数据将被从一个光标拉动。

I am wanting to create my own List Adapter using BaseAdapter to show a listView, with multiple items from a Database. I know this can be done using the Simple Cursor Adapter, but I am looking to handle rows differently, so I want to be able to draw each row by overriding getView. The data would be pulled from a cursor.

我知道这code是丑陋获取光标数据，但假设我有填充游标。你有没有在这一点，如果第8列包含图像资源ID有什么建议。

I know this code is ugly for getting to the cursor data, but assuming I have populated a cursor. What suggestions do you have on this if column 8 contains the image resource id. :

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    cursor.moveToPosition(position);
    ImageView i = new ImageView(mContext);
    i.setImageResource(cursor.getShort(8));
    i.setAdjustViewBounds(true);
    i.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

    return i;
}

你有一个BaseAdapter任何好的例子使用光标正在绘制？

Do you have any good examples of a BaseAdapter being drawn using a cursor?

推荐答案

尝试调用 notifyDataSetChanged（）从内部的方法 BaseAdapter 本身。

Try calling notifyDataSetChanged() from a method inside the BaseAdapter itself.

见<一的方法href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List8.html"相对=nofollow>的API演示的List8 作为一个例子。
