如何创建双向无限 ViewPager?在现有的元素中,元素的位置可以> = 0,但不是<0.
我有2个活动,我在那里覆盖了onKeyUp事件:
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
Log.d(TAG, "Key up: " + keyCode);
return super.onKeyUp(keyCode, event);
}

第一个是应用程序的主要活动,另一个是次要活动.第一个工作正常,但第二个捕获Left-Right-Up-Down但不是Center click的事件.为什么?
之前我曾多次使用过bootstrap,但现在在我的GAE项目中我遇到了一个问题 - 输入元素的高度非常小.例如,按钮就可以了:

HTML代码:
<div class="container">
<div class="row">
<div class="span6 pull-right">
<div class="well well-small">
<form>
<input id="length" class="input-small" name="length" type="text" value="8">
<br/>
<input type="number" value="8">
<br/>
<input type="submit" class="btn btn-success" value="Generate">
<!-- etc -->

编辑2:删除高度:来自bootstrap的20px规则,现在没关系.但为什么它在那里?
Bootstrap版本是2.2.1.屏幕截图是在Chrome 23.0.1271.95,Mac OS X 10.8中制作的.
我删除了项目中的所有迁移,删除了数据库并尝试使用manage.py makemigrations命令重新创建迁移.但是我收到了错误:
