通过Location获取Address的使用！
大家好，上一节我讲了一下如何通过LocationManager来获取Location，没有看过上一节的同学，可以点击如下链接返回查看：
Android高手进阶教程十四之---Android Location的使用!
我们获取Location的目的之一肯定是有获取这个位置的详细地址，而我们有了Location在来获取Address就相对简单多了，因为GoogleApi已经封装好了方法，我们只需呀通过Location获取GeoPoint,然后在通过GeoPoint来获取我们想要的Address.下面是我做的一个简单的Demo.
第一步新建一个Android工程LocationDemo，注意这里选用的是(Google APIs)，下面是文件目录结构
第二步： 修改main.xml(相比第十四节增加了一个address的TextView)，代码如下:
view plaincopy to clipboardprint?
01.<?xml version="1.0" encoding="utf-8"?>
02.<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
03. android:orientation="vertical"
04. android:layout_width="fill_parent"
05. android:layout_height="fill_parent"
06. >
07.<TextView
08. android:id="@+id/longitude"
09. android:layout_width="fill_parent"
10. android:layout_height="wrap_content"
11. android:text="longitude:"
12. />
13.<TextView
14. android:id="@+id/latitude"
15. android:layout_width="fill_parent"
16. android:layout_height="wrap_content"
17. android:text="latitude:"
18. />
19.<TextView
20. android:id="@+id/address"
21. android:layout_width="fill_parent"
22. android:layout_height="wrap_content"
23. />
24.</LinearLayout>
view plaincopy to clipboardprint?
01.<?xml version="1.0" encoding="utf-8"?>
02.<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
03. android:orientation="vertical"
04. android:layout_width="fill_parent"
05. android:layout_height="fill_parent"
06. >
07.<TextView
08. android:id="@+id/longitude"
09. android:layout_width="fill_parent"
10. android:layout_height="wrap_content"
11. android:text="longitude:"
12. />
13.<TextView
14. android:id="@+id/latitude"
15. android:layout_width="fill_parent"
16. android:layout_height="wrap_content"
17. android:text="latitude:"
18. />
19.<TextView
20. android:id="@+id/address"
21. android:layout_width="fill_parent"
22. android:layout_height="wrap_content"
23. />
24.</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/longitude"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="longitude:"
/>
<TextView
android:id="@+id/latitude"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="latitude:"
/>
<TextView
android:id="@+id/address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
第三步:修改LocationDemo.java(增加了两个方法)代码如下:
view plaincopy to clipboardprint?

70.
71. double geoLatitude = (int) gp.getLatitudeE6() / 1E6;
72. double geoLongitude = (int) gp.getLongitudeE6() / 1E6;
73.
74. List<Address> lstAddress = gc.getFromLocation(geoLatitude,
75. geoLongitude, 1);
76. if (lstAddress.size() > 0) {

78. }
79. }

}
}
} catch (Exception e) {

}
第四步:最重要一步在AndroidManiefest.xml中导入Google Api(第14行代码)库,代码如下:
view plaincopy to clipboardprint?
01.<?xml version="1.0" encoding="utf-8"?>
02.<manifest xmlns:android="http://schemas.android.com/apk/res/android"
03. package="com.android.tutor"

[2] 自定义ViewGroup 实现拖动和快速滚动的效果
来源: 互联网 发布时间: 2014-02-18
自定义ViewGroup 实现拖动跟快速滚动的效果
之前做到个项目要类似listView或者GridView中的控件移动的效果（主屏上所有程序列表上的效果）：
1：子控件跟着手指移动
2：快速拨动一下，根据拨动的速度 滑动过去
3：拖过头，放手后弹回去
但是用listView或者GridView又不好实现项目要求的其他效果..于是继承viewGroup实现以上效果。
既然要获取拨动速度，并以此滑动。首先想到了OnGestureListener 这个接口，实现这个接口并实现其onFling方法.
还要控制拖动。重写onTouchEvent方法，并在其中控制内容控件的拖动，反弹等效果
这时候基本已经完成了。。。。测试了一下了，发现了一个问题，当手指点在viewGroup上
进行 拖动是没问题的，但是在子控件上就不行了，这是事件响应的问题 那么还要做如面的处
理:实现onInterceptTouchEvent方法，判断是拖动事件时 ，将事件传递下去。
好了，代码就不在上面贴了，如果有需要可以下载附件。 多谢阅读

最好是左右拖动的
