这是我的自定义适配器：

public View getView(int position, View convertView, ViewGroup parent) {

    View row = super.getView(position, convertView, parent);


    Cursor cursbbn  = getCursor();



    if (row == null)

    {

        LayoutInflater inflater = (LayoutInflater) localContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.listtype, null);
    }


    String Title = cursbbn.getString(2);
    String Readyin = cursbbn.getString(4);
    String Faovoites=cursbbn.getString(8);


    TextView titler=(TextView)row.findViewById(R.id.listmaintitle);
    TextView readyinr=(TextView)row.findViewById(R.id.listreadyin);

     int colorPos = position % colors.length;
     row.setBackgroundColor(colors[colorPos]);

    titler.setText(Title);
    readyinr.setText(Readyin);

    ImageView picture = (ImageView) row.findViewById(R.id.imageView1);
    Bitmap bitImg = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.seafood);

    if(Title.contentEquals("Fajita Raps"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg));


    if (Faovoites.contentEquals("YES")) {

        ImageView star = (ImageView) row.findViewById(R.id.favoritesicon);
        star.setVisibility(View.VISIBLE);

    }

    return row;
}

这是我的 Search Edittext aftertextchanged 事件

public void afterTextChanged(final Editable s) {

            final String[] columns = new String[] {

            "_id", COL_SanID, COL_SanTitle, COL_SanCat, COL_SanReadyin,

            COL_SandServing, COL_SandIngred, COL_SandDirect, COL_SandFavor };

            Bundle extrass = getIntent().getExtras();

            final String Type = extrass.getString("CategoryType");

            mAdapter.setFilterQueryProvider(new FilterQueryProvider() {
                public Cursor runQuery(CharSequence constraint) {

                    String value = "%" + constraint + "%";
                    String Type2 = "%" + Type + "%";

                    curs = mDb.query(TABLE_NAME, columns, COL_SanTitle
                            + " LIKE ? And " + COL_SanCat + " LIKE ?",
                            new String[] { value, Type2 }, null, null,
                            COL_SanTitle + " ASC");

                    return curs;

                }
            });

最后：Logcat 异常

当getView()你打电话时，localCursor.moveToPosition(position);你会得到java.lang.IllegalStateException: attempt to re-open an already-closed object: android.database.sqlite.SQLiteQuery.

为什么会发生这种情况？因为一旦对列表视图应用了过滤，旧的光标就会关闭，而使用新的光标。getCursor()您可以通过调用而不是跟踪初始光标来获取当前的底层光标。摆脱Cursor localCursor并使用getCursor()。
