在android中将对象arraylist转换为光标

在android中将对象arraylist转换为光标,android,arraylist,pojo,android-cursor,Android,Arraylist,Pojo,Android Cursor,POJO类GridItem: public class GridItem { int id; String path; String name; String chr; int headerId; public GridItem(String path, String name, String chr){ this.path = path; this.name = name; this.chr

POJO类GridItem:

public class GridItem {

    int id;

    String path;
    String name;
    String chr;
    int headerId;


    public GridItem(String path, String name, String chr){
        this.path = path;
        this.name = name;
        this.chr = chr;
    }
}
在活动中:

ArrayList<GridItem> books = new ArrayList<GridItem>(); 

如果任何人有解决方案,请在此处公开。

您可能需要使用它,它是一个由对象数组支持的可变游标实现。使用newRow()添加行。根据需要自动扩展内部容量。

如果
ArrayList
用于数据源,那么为什么不通过扩展
BaseAdapter
ArrayAdapter
而不是
SimpleCursorAdapter
,来创建自定义适配器呢?我已经尝试过了。。但是sectionindexer没有显示..看哪一个与ArrayAdapter@ρаσѕρєK一起工作我也试过了,但没有工作。你遇到了什么问题?
static class YOUR_ADAPTER extends SimpleCursorAdapter implements SectionIndexer {

private AlphabetIndexer mIndexer;

 YOUR_ADAPTER (Context context, AlbumBrowserActivity currentactivity,
            int layout, Cursor cursor, String[] from, int[] to) {
        super(context, layout, cursor, from, to);

        getColumnIndices(cursor);
    } 

    private void getColumnIndices(Cursor cursor) {
        if (cursor != null) {
            YOUR_COLUMN = cursor.getColumnIndexOrThrow(WHAT_YOU'RE_SORTING);

            if (mIndexer != null) {
                mIndexer.setCursor(cursor);
            } else {
                mIndexer = new AlphabetIndexer(cursor, YOUR_COLUMN, mResources.getString(
                        R.string.fast_scroll_alphabet));
            }
        }
    }

 public Object[] getSections() {
        return mIndexer.getSections();
    }

 public int getPositionForSection(int section) {
        return mIndexer.getPositionForSection(section);
    }

 public int getSectionForPosition(int position) {
        return 0;
    }
}
