The earthquake project, mainly reads the Survey (subscription source) provided by the USGS (United States Geological feeds, the United States Bureau of Exploration) for displaying data;

Need to read the data on the Internet, format resolution (parse), the data type is atom type, similar to XML.

Specific design of earthquake:

New project: Earthquake

1. New Quake (Quake.java) class, display seismic data.

Location: Java->package->quake

Package Mzx.spike.earthquake.app;  
      
Import android.location.Location;  
Import Java.text.SimpleDateFormat;  
      
Import Java.util.Date;  
    public class Quake {private date date;  
    Private String details;  
    Private Location Location;  
    private double magnitude;  
      
    Private String link;  
    Public Date getDate () {return date;}  
    Public String Getdetails () {return details;}  
    Public Location getLocation () {return Location;}  
    Public double Getmagnitude () {return magnitude;}  
      
    Public String GetLink () {return link;}  
        Public Quake (Date _d, string _det, Location _loc, double _mag, string _link) {date = _d;  
        Details = _det;  
        location = _loc;  
        magnitude = _mag;  
    link = _link;  
        @Override public String toString () {SimpleDateFormat SDF = new SimpleDateFormat ("hh.mm");  
        String datestring = Sdf.format (date); Return DAtestring + ":" + magnitude + "" + details; }  
      
}

Detailed

1. Types of display: date, dates; Details, detailed information, location; location, position; magnitude, magnitude; link, links;

2. Get () method, return information; constructor function, assigning initial value; ToString (), default output information;

2. Modify activity_main.xml and add fragment.

Location: Res->layout->activity_main.xml

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"
    xmlns:tools= "http:// Schemas.android.com/tools "
    android:layout_width=" match_parent "
    android:layout_height=" Match_parent "
    android:paddingleft= "@dimen/activity_horizontal_margin"
    android:paddingright= "@dimen/activity_ Horizontal_margin "
    android:paddingtop=" @dimen/activity_vertical_margin "
    android:paddingbottom=" @dimen Activity_vertical_margin "
    tools:context=" mzx.spike.earthquake.app.MainActivity ">  
      
    <fragment Android:name= "Mzx.spike.earthquake.app.EarthquakeListFragment"
        android:id= "@+id/earthquakelistfragment"
        android:layout_width= "match_parent"
        android:layout_height= "match_parent"
     />  
</ Relativelayout>

Add fragment to specify the implementation (. java) file location.
