EasyAndroid

该开源库参考了ActiveAndroid，retrofit，并使用了sqlcipher-for-android和android-async-http，在这些库的思想上做了一些适合自己项目的扩展。本着方便自己开发Android程序的目的诞生了这个库。目前该库还在不断完善中

大纲

• EasyLog
• EasyDb
• EasyFile
• EasyHttp
• EasyReflection

###EasyLog 用法很简单，跟android得Logcat用法一样，但是EasyLog会很方便的帮你打出一些额外的信息。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    EasyLog.d("hello easy android");
}

运行程序，打印出下面的log信息:

03-20 17:20:18.040: E/com.amida.easyandroid.test.MainActivity(8844): [onCreate:40]hello easy android

EasyLog中以当前的类名为tag，在message中打印出了额外的信息，包括所在函数，代码行数。 EasyLog在我们调试程序的时候，还可以打印长log，通常我们在打印很长的log的时候，后面超出的部分就不现实了, 使用EasyLog，会方便的为我们分几次打印出整个字符串，如下:

StringBuilder longText = new StringBuilder();
    for (int i = 0; i < 4000; i ++) {
        longText.append(i);
    }
    EasyLog.d(longText.toString());

###EasyDb

1. 加密的数据库，更安全。
2. 不需要用户敲入大量的databaseHelper的代码。
3. 简单的数据库操作。

#####配置

1. 将icudt46l.zip拷贝到项目assets目录下。

2. 在AndroidManifest.xml文件的Application内加入

    <meta-data
        android:name="DB_NAME"
        android:value="sampledb" >
    </meta-data>
    <meta-data
        android:name="DB_VERSION"
        android:value="1" >
    </meta-data>
    <meta-data
        android:name="DB_TABLSE_PACKAGE"
        android:value="com.example.textviewfinder.dbbean" >
    </meta-data>
   

   设置数据库名，版本，数据库表结构所在的包。

3. 新建自己的Application类

    public class SampleApp extends Application{
    
    @Override
    public void onCreate() {
    super.onCreate();
            
    EasyDb.getInstance().init(this, "secretkey"); 
    }
   

   初始化数据库。

4. 在com.amida.easydb.DbTable下面新建你需要的数据库表

    public class Team extends DbTable {
    @Column(name = "teamName")
    private String teamName;
    @Column(name = "teamLeader")
    private String teamLeader;
    
    public String getTeamName() {
        return teamName;
    }
        
    public void setTeamName(String teamName) {
        this.teamName = teamName;
    }
        
    public String getTeamLeader() {
        return teamLeader;
    }
    
    public void setTeamLeader(String teamLeader) {
        this.teamLeader = teamLeader;
    }
    
    }
   

   定义表结构，表名就是类名，列名由Column标签指定。

#####保存数据

Team team = new Team();
team.setTeamLeader("liaoqianchuan");
team.setTeamName("OneTeam");
team.save();

#####查询数据

ArrayList<Team> teams = new Select().from(Team.class).orderBy("teamLeader").execute();

#####删除数据

team.delete();

new Delete().from(Team.class).where("teamName='liaoqianchuan'").execute();

#####更新数据

ArrayList<Team> teams = new Select().from(Team.class).orderBy("teamLeader").execute();

for (Team tmpTeam : teams) {
    tmpTeam.setTeamLeader("Gebi LaoWang");
    tmpTeam.save();
}

###EasyHttp

• 用户只需定义Service的接口，不需要写Http的实现
• 可以很方便的扩展其他业务逻辑。
• 支持假数据，比如只想本地调试，而不想和服务器联调，可以很方便的设置假数据供本地测试。

#####定义接口 如下所示，定义了两个接口，第一个是取IP信息的接口，第二个是下载图片的接口。 EasyHttp标签：

1. url - 定义该接口指向的url。

2. dummyData - 定义该接口返回的假数据。

3. apiType - 有下载文件和一般的获取数据类型

   public interface TestService extends IService { @EasyHttp( url = Constants.API_IPINFO, dummyData = DummyData.DUMMY_IPINFO ) void getIpInfo(Object request, ResponseListener responseListener);

   @EasyHttp( apiType=ApiType.DOWNLOADFILE, url = Constants.API_DOWNPIC, dummyData=DummyData.DUMMY_PIC ) void downloadPic(Object request, ResponseListener responseListener, File file); }

#####基本使用 如下所示，我们定义好API请求中需要传递的参数的数据结构。

public class RequestIpInfo {
private String format;

public String getFormat() {
    return format;
}

public void setFormat(String format) {
    this.format = format;
}
}

在我们调用接口的时候，这个数据结构中的值会自动帮我们被转换成如下的形式：

http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json

接下来，我们只需要在回调函数中实现我们的业务逻辑。

RequestIpInfo request = new RequestIpInfo();
    request.setFormat("json");
    ResponseListener responseListener = new ResponseListener<ResponseIpInfo>() {

        @Override
        public void onSuccess(ResponseIpInfo response) {
            super.onSuccess(response);
            EasyLog.d("response:" + new Gson().toJson(response));
        }

        @Override
        public void onFailure(int errorCode, String errorMessage) {

        }

        @Override
        public void onProgress(int bytesWritten, int totalSize) {

        }

    };

((TestService) ServiceFactory.create(this, ServiceType.NET, TestService.class)).getIpInfo(request, responseListener);

#####下载文件 下载文件和前面的方式类似。

private void testEasyDownload() {
    final String picPath = Environment.getExternalStorageDirectory() + File.separator + "dddd.png";
    EasyLog.d("path: " + picPath);
    File picFile = new File(picPath);
    
    RequestDownPic request = new RequestDownPic();
    ResponseListener responseListener = new ResponseListener<File>() {
    
        @Override
        public void onSuccess(File response) {
            super.onSuccess(response);
        }
            
        @Override
        public void onFailure(int errorCode, String errorMessage) {

        }

        @Override
        public void onProgress(int bytesWritten, int totalSize) {

        }
    };

    ((TestService) ServiceFactory.create(this, ServiceType.NET, TestService.class)).downloadPic(request, responseListener, picFile);
}

#####返回假数据
要本地测试，返回我们定义的假数据，只需要在定义API接口的时候声明dummyData，然后创建一个ServiceType.Dummy类型的Service就可以了

((TestService) ServiceFactory.create(this, ServiceType.DUMMY, TestService.class)).downloadPic(request, responseListener, picFile);

#####缓存 程序可以将API请求得到的数据缓存到本地，在请求API的时候，可以先查询本地缓存，如果缓存没有，再查询服务器。 也很方便，值需创建一个ServiceType.CACHE的Service就可以了。

((TestService) ServiceFactory.create(this, ServiceType.CACHE, TestService.class)).downloadPic(request, responseListener, picFile);
