推荐答案

我假设你使用的是SimpleCursorAdapter a href =http://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html =nofollow> OnItemClickListener ：

I assume that you are using a SimpleCursorAdapter (or similar), so I would use the OnItemClickListener:

listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // id references the SQLiteDatabase _id column
    }
});
