autocompletetextview过滤器下拉数据

Question

我已经创建了自定义autocompletetextview组件。我还为自动完成文本数据创建了一个populateList方法。

final com.example.admin.ctronhot.autocomleteclass autocomplete=(com.example.admin.ctronhot.autocomleteclass)findViewById(R.id.abc);
    final String sql="select * from g101 where desc LIKE '%" + autocomplete.getText().toString() + "%'";
    final String[] mfieldsa=new String[]{"desc"};
    final int[] mobjectsa=new int[]{R.id.desc};
    autocomplete.populateList(R.layout.brow_g101_layout, sql, "desc", aa, mfieldsa, mobjectsa, order.this);

显示下拉数据，但未按照autocomplete.getText.toString（）中的类型过滤数据

这是我的函数populateList

    public void populateList(Integer _layoutfile, final String sqlaa, String mfieldget, com.example.admin.ctronhot.autocomleteclass mauto,
                         String[] mfields, int[] mobjects, Context mcontext) {
    SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(co.mcurd_data_path_, null);
    Cursor cursor = db.rawQuery(sqlaa null);
    int layoutResourceId = 0;
    final SimpleCursorAdapter adapter = new SimpeCursorAdapter(
            mcontext,        // Context
            _layoutfile,    // Row layout template
            cursor,                    // cursor (set of DB records to map)
            mfields,        // DB Column names
            mobjects                // View IDs to put information in
            , layoutResourceId
    );
    adapter.setCursorToStringConverter(new SimpleCursorAdapter.CursorToStringConverter() {
        @Override
        public CharSequence convertToString(Cursor cursor) {
            final int colIndex = cursor.getColumnIndexOrThrow("desc");
            return cursor.getString(colIndex);
        }
    });

    adapter.setFilterQueryProvider(new FilterQueryProvider() {
        @Override
        public Cursor runQuery(CharSequence description) {
            SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(co.mcurd_data_path_, null);
            Cursor managedCursor = db.rawQuery(sqlaa, null);

            return managedCursor;
        }
    });
    mauto.setThreshold(1);
    mauto.setAdapter(adapter);
}

请帮帮我。 提前谢谢。
