下个是 cursorloader

import android.content.Context;
import android.content.CursorLoader;
import android.database.Cursor;
import android.net.Uri;

public class MyCursorLoader extends CursorLoader {
	 Cursor mCursor;
	public MyCursorLoader(Context context, Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
		super(context, uri, projection, selection, selectionArgs, sortOrder);
	}
	 @Override
	    public void onContentChanged() {
	        if (!mCursor.isClosed()) {
	            deliverResult(mCursor);
	        }
	        forceLoad();
	    }

	    @Override
	    public Cursor loadInBackground() {
	        mCursor = super.loadInBackground();
	        return mCursor;
	    }

}
