更改android中ListView的Imageview onItemClickListener的图像

我正在使用自定义 ListView 显示图像和文本,使用 Cursor 现在 onItemClickListener() ,我想更改的图像 ImageView 我还想更改textColor TextView 。我想禁用该项,使其无法单击哪个用户 Click 。我试过好几种方法,但都没有奏效。
如何做到这一点?

XML代码:

        <ImageView
            android:id="@+id/icon"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:contentDescription="@string/queimg"
            android:src="@drawable/ic_answer" />

        <TextView
            android:id="@+id/option"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:paddingTop="14dp"
            android:layout_toRightOf="@+id/icon"
            android:text="hello" />

Java代码:

        final List<String> lstOption = new ArrayList<String>();

        ArrayList<Map<String, String>> arrlist = new ArrayList<Map<String, String>>();

        Map<String, String> m = null;
        if (option != null) {
            if (option.moveToFirst()) {
                do {
                    lstOption.add(option.getString(option
                            .getColumnIndex("Option")));

                    m = new HashMap<String, String>();
                    m.put("option",
                            option.getString(option.getColumnIndex("Option")));

                    arrlist.add(m);
                } while (option.moveToNext());
            }
        }

        SimpleAdapter adapter = new SimpleAdapter(this, arrlist,
                R.layout.topicwisequestion, new String[] { "option" },
                new int[] { R.id.option });


lvTWOptions.setAdapter(adapter);
lvTWOptions.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
}
});
