#HTTP编程
Http编程有请求和响应，这里我们把对json数据年度解析放到这一部分来讲解：
/** * Http 请求 */ public class HttpRequestInfo { public static final String TAG = "HttpRequestInfo"; /* Http 请求的 URL */ private String requestUrl; private int requestID; private Map<String, String> requestParams; public HttpRequestInfo(String url) { this.setRequestUrl(url); requestParams = new HashMap<String, String>(); } public HttpRequestInfo(String url, Map<String, String> params) { this.setRequestUrl(url); this.setRequestParams(params); } public String getRequestUrl() { return requestUrl; } public void setRequestUrl(String requestUrl) { this.requestUrl = requestUrl; } public Map<String, String> getRequestParams() { return requestParams; } public void setRequestParams(Map<String, String> requestParams) { this.requestParams = requestParams; } public String getParamsStr() { String str = ""; if (requestParams != null) { for (Entry<String, String> entry : requestParams.entrySet()) { String key = entry.getKey(); String val = entry.getValue(); key = URLEncoder.encode(key); val = URLEncoder.encode(val); str += key + "=" + val + "&"; } } if (str.equals("")) { return null; } LogUtil.i(TAG, this.requestUrl + str); return str; } public HttpRequestInfo putParam(String key, String value) { this.requestParams.put(key, value); return this; } public int getRequestID() { return requestID; } public void setRequestID(int requestID) { this.requestID = requestID; } }对于响应：
/** * Http 响应 */ public class HttpResponseInfo { public enum HttpTaskState { STATE_OK, STATE_NO_NETWORK_CONNECT, STATE_TIME_OUT, STATE_UNKNOWN, } public HttpResponseInfo(String result, HttpTaskState state) { this.result = result; this.state = state; } private HttpTaskState state; private String result; public HttpTaskState getState() { return state; } public void setState(HttpTaskState state) { this.state = state; } public String getResult() { return result; } public void setResult(String result) { this.result = result; } }
SQLiteOpenHelper有onCreate（）、onUpgrade（）两个方法。
private static class DatabaseHelper extends SQLiteOpenHelper { public DatabaseHelper(Context context, String name, CursorFactory factory, int version) { super(context, DB_NAME, null, version); } @Override public void onCreate(SQLiteDatabase db) { //创建所有数据库表 db.execSQL(DB_CREATE_FUND); db.execSQL(DB_CREATE_FAV_FUND); db.execSQL(DB_CREATE_HELPS_INFO); db.execSQL(DB_CREATE_FUND_DETAIL); db.execSQL(DB_CREATE_MSG); } // 更新基金数据 @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE_FUND); db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE_FAV_FUND); db.execSQL("DROP TABLE IF EXISTS " + DB_CREATE_HELPS_INFO); db.execSQL("DROP TABLE IF EXISTS " + DB_CREATE_FUND_DETAIL); db.execSQL("DROP TABLE IF EXISTS " + DB_CREATE_MSG); onCreate(db); } }
当然了，仅仅通过一篇博文是不可逆完全完整的说完整个项目了，这里写的仅仅是冰山一角，更多的内容还是希望读者自己去发现并学到里面的精华部分！当然咯，我相信有一部分人读了也基本上没看懂我写的是什么，那么请下载源码看看，互相学习咯！
