我从Droid X和Droid Pro收到了奇怪的崩溃报告.

我是ClickableSpan的子类,为我的TextView中的链接自定义文本样式.

private static class LinkSpan extends ClickableSpan {
    @Override
    public void onClick(View widget) {
         // code...
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
        ds.setTypeface(Typeface.create(ds.getTypeface(), Typeface.BOLD));
        ds.setColor(0xff336699);
    }
}

我希望在处于按下状态时更改样式,或者用户触摸链接.(比如a:hover在css中)但是我无法找到一种获得当前状态的方法updateDrawState.

有办法处理这个吗？如果我无法更改文本样式,我希望至少能够更改背景颜色.

按注释编辑,您可以在按下时更改单个ClickableSpan的文本颜色,而不会影响同一TextView中的其他ClickableSpans

我试图改变现有序列的最小值.

首先我试过了

ALTER SEQUENCE product_id_seq MINVALUE 10000;

和我ERROR: START value (1) cannot be less than MINVALUE (10000).

所以我试过了

ALTER SEQUENCE product_id_seq MINVALUE 10000 RESTART WITH 10000;

但得到了同样的错误.

当然我可以放弃它并创建一个新的,但我认为应该有办法做到这一点.我正在使用Postgres 8.4.7.

我给了android:singleLine="true"选项EditTextPreference,当对话框中的编辑框有焦点时,软件键盘显示"完成"按钮代替Enter键.但是,如果我按下完成按钮,只有软键盘关闭,我仍然需要单击对话框上的完成按钮.

无论如何在软件键盘上输入key和ime动作键来关闭对话框并应用新值？
