我有一个列表视图,显示一组行,每行都是可点击的.现在,我希望在一个标题下对相似类型的行进行分组,如图所示(模拟).有些人可以为此提供建议或提供方法.

我正在尝试在HorizontalScrollView滚动时收听事件.试过这个,但它没有打印任何东西.
HorizontalScrollView headerScrollView = new HorizontalScrollView(this);
headerScrollView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
Log.i("hv1",event.toString());
Log.i("hv1","HELLO");
return false;
}
});

实际问题是,我想一次滚动两个HorizontalScrollView...... 当至少其中一个滚动时,它们都需要同时滚动.任何解决方法?
我使用下面的答案,然后尝试实现这个,但我不知道我需要如何使用类中的方法.
TestHorizontalScrollView headerScrollView = (TestHorizontalScrollView) findViewById(R.id.headerHv);

有人可以告诉我是否有办法将kml文件加载到android中的谷歌地图.
谢谢

我有一个 OAuth2 实现,对于授权类型 = 密码工作正常。现在我需要添加一个限制相同用户/密码组合的逻辑,如果用户较早登录,则允许再次登录。为此,我研究并认为我要创建一个扩展 DefaultTokenServices 类的新类 (MyDefaultTokenService),然后在重写的 createAccessToken 方法中添加我的逻辑。但是由于某种原因,当我调试和测试时,我没有点击放置在 MyDefaultTokenService 类中的断点。它总是命中 Springboot 的 DefaultTokenServices 类。我不知道我哪里出错了,有人可以请。
