XUtils是基于afinal開發(fā)的,比afinal穩(wěn)定性提高了不少,下面是介紹:

xUtils簡介

  • xUtils 包含了很多實(shí)用的android工具。
  • xUtils 最初源于Afinal框架,進(jìn)行了大量重構(gòu),使得xUtils支持大文件上傳,更全面的http請(qǐng)求協(xié)議支持(10種謂詞),擁有更加靈活的ORM,更多的事件注解支持且不受混淆影響...
  • xUitls最低兼容android 2.2 (api level 8)

  • 目前xUtils主要有四大模塊:
    • DbUtils模塊:

      • android中的orm框架,一行代碼就可以進(jìn)行增刪改查;
      • 支持事務(wù),默認(rèn)關(guān)閉;
      • 可通過注解自定義表名,列名,外鍵,唯一性約束,NOT NULL約束,CHECK約束等(需要混淆的時(shí)候請(qǐng)注解表名和列名);
      • 支持綁定外鍵,保存實(shí)體時(shí)外鍵關(guān)聯(lián)實(shí)體自動(dòng)保存或更新;
      • 自動(dòng)加載外鍵關(guān)聯(lián)實(shí)體,支持延時(shí)加載;
      • 支持鏈?zhǔn)奖磉_(dá)查詢,更直觀的查詢語義,參考下面的介紹或sample中的例子。
    • ViewUtils模塊:

      • android中的ioc框架,完全注解方式就可以進(jìn)行UI,資源和事件綁定;
      • 新的事件綁定方式,使用混淆工具混淆后仍可正常工作;
      • 目前支持常用的20種事件綁定,參見ViewCommonEventListener類和包c(diǎn)om.lidroid.xutils.view.annotation.event。
    • HttpUtils模塊:

      • 支持同步,異步方式的請(qǐng)求;
      • 支持大文件上傳,上傳大文件不會(huì)oom;
      • 支持GET,POST,PUT,MOVE,COPY,DELETE,HEAD,OPTIONS,TRACE,CONNECT請(qǐng)求;
      • 下載支持301/302重定向,支持設(shè)置是否根據(jù)Content-Disposition重命名下載的文件;
      • 返回文本內(nèi)容的請(qǐng)求(默認(rèn)只啟用了GET請(qǐng)求)支持緩存,可設(shè)置默認(rèn)過期時(shí)間和針對(duì)當(dāng)前請(qǐng)求的過期時(shí)間。
    • BitmapUtils模塊:

      • 加載bitmap的時(shí)候無需考慮bitmap加載過程中出現(xiàn)的oom和android容器快速滑動(dòng)時(shí)候出現(xiàn)的圖片錯(cuò)位等現(xiàn)象;
      • 支持加載網(wǎng)絡(luò)圖片和本地圖片;
      • 內(nèi)存管理使用lru算法,更好的管理bitmap內(nèi)存;
      • 可配置線程加載線程數(shù)量,緩存大小,緩存路徑,加載顯示動(dòng)畫等...

    使用xUtils快速開發(fā)框架需要有以下權(quán)限:

    <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    混淆時(shí)注意事項(xiàng):

    • 添加Android默認(rèn)混淆配置${sdk.dir}/tools/proguard/proguard-android.txt
    • 不要混淆xUtils中的注解類型,添加混淆配置:-keep class * extends java.lang.annotation.Annotation { *; }
    • 對(duì)使用DbUtils模塊持久化的實(shí)體類不要混淆,或者注解所有表和列名稱@Table(name="xxx"),@Id(column="xxx"),@Column(column="xxx"),@Foreign(column="xxx",foreign="xxx");

    DbUtils使用方法:

    DbUtils db = DbUtils.create(this); User user = new User(); //這里需要注意的是User對(duì)象必須有id屬性,或者有通過@ID注解的屬性 user.setEmail("wyouflf@qq.com"); user.setName("wyouflf"); db.save(user); // 使用saveBindingId保存實(shí)體時(shí)會(huì)為實(shí)體的id賦值... // 查找 Parent entity = db.findById(Parent.class, parent.getId()); List<Parent> list = db.findAll(Parent.class);//通過類型查找Parent Parent = db.findFirst(Selector.from(Parent.class).where("name","=","test"));// IS NULL Parent Parent = db.findFirst(Selector.from(Parent.class).where("name","=", null)); // IS NOT NULL Parent Parent = db.findFirst(Selector.from(Parent.class).where("name","!=", null));// WHERE id<54 AND (age>20 OR age<30) ORDER BY id LIMIT pageSize OFFSET pageOffset List<Parent> list = db.findAll(Selector.from(Parent.class).where("id" ,"<", 54).and(WhereBuilder.b("age", ">", 20).or("age", " < ", 30)).orderBy("id").limit(pageSize).offset(pageSize * pageIndex));// op為"in"時(shí),最后一個(gè)參數(shù)必須是數(shù)組或Iterable的實(shí)現(xiàn)類(例如List等) Parent test = db.findFirst(Selector.from(Parent.class).where("id", "in", new int[]{1, 2, 3})); // op為"between"時(shí),最后一個(gè)參數(shù)必須是數(shù)組或Iterable的實(shí)現(xiàn)類(例如List等) Parent test = db.findFirst(Selector.from(Parent.class).where("id", "between", new String[]{"1", "5"}));DbModel dbModel = db.findDbModelAll(Selector.from(Parent.class).select("name"));//select("name")只取出name列 List<DbModel> dbModels = db.findDbModelAll(Selector.from(Parent.class).groupBy("name").select("name", "count(name)")); ...List<DbModel> dbModels = db.findDbModelAll(sql); // 自定義sql查詢 db.execNonQuery(sql) // 執(zhí)行自定義sql ...

    ViewUtils使用方法

    • 完全注解方式就可以進(jìn)行UI綁定和事件綁定。
    • 無需findViewById和setClickListener等。
    // xUtils的view注解要求必須提供id,以使代碼混淆不受影響。 @ViewInject(R.id.textView) TextView textView;//@ViewInject(vale=R.id.textView, parentId=R.id.parentView) //TextView textView;@ResInject(id = R.string.label, type = ResType.String) private String label;// 取消了之前使用方法名綁定事件的方式,使用id綁定不受混淆影響 // 支持綁定多個(gè)id @OnClick({R.id.id1, R.id.id2, R.id.id3}) // or @OnClick(value={R.id.id1, R.id.id2, R.id.id3}, parentId={R.id.pid1, R.id.pid2, R.id.pid3}) // 更多事件支持參見ViewCommonEventListener類和包c(diǎn)om.lidroid.xutils.view.annotation.event。 @OnClick(R.id.test_button) public void testButtonClick(View v) { // 方法簽名必須和接口中的要求一致... } ... //在Activity中注入: @Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);ViewUtils.inject(this); //注入view和事件...textView.setText("some text...");... } //在Fragment中注入: @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.bitmap_fragment, container, false); // 加載fragment布局ViewUtils.inject(this, view); //注入view和事件... } //在PreferenceFragment中注入: public void onActivityCreated(Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);ViewUtils.inject(this, getPreferenceScreen()); //注入view和事件... } // 其他重載 // inject(View view); // inject(Activity activity) // inject(PreferenceActivity preferenceActivity) // inject(Object handler, View view) // inject(Object handler, Activity activity) // inject(Object handler, PreferenceGroup preferenceGroup) // inject(Object handler, PreferenceActivity preferenceActivity)

    HttpUtils使用方法:

    普通get方法

    HttpUtils http = new HttpUtils(); http.send(HttpRequest.HttpMethod.GET,"http://www.lidroid.com",new RequestCallBack<String>(){@Overridepublic void onLoading(long total, long current, boolean isUploading) {testTextView.setText(current + "/" + total);}@Overridepublic void onSuccess(ResponseInfo<String> responseInfo) {textView.setText(responseInfo.result);}@Overridepublic void onStart() {}@Overridepublic void onFailure(HttpException error, String msg) {} });

    使用HttpUtils上傳文件 或者 提交數(shù)據(jù) 到服務(wù)器(post方法)

    RequestParams params = new RequestParams(); params.addHeader("name", "value"); params.addQueryStringParameter("name", "value");// 只包含字符串參數(shù)時(shí)默認(rèn)使用BodyParamsEntity, // 類似于UrlEncodedFormEntity("application/x-www-form-urlencoded")。 params.addBodyParameter("name", "value");// 加入文件參數(shù)后默認(rèn)使用MultipartEntity("multipart/form-data"), // 如需"multipart/related",xUtils中提供的MultipartEntity支持設(shè)置subType為"related"。 // 使用params.setBodyEntity(httpEntity)可設(shè)置更多類型的HttpEntity(如: // MultipartEntity,BodyParamsEntity,FileUploadEntity,InputStreamUploadEntity,StringEntity)。 // 例如發(fā)送json參數(shù):params.setBodyEntity(new StringEntity(jsonStr,charset)); params.addBodyParameter("file", new File("path")); ...HttpUtils http = new HttpUtils(); http.send(HttpRequest.HttpMethod.POST,"uploadUrl....",params,new RequestCallBack<String>() {@Overridepublic void onStart() {testTextView.setText("conn...");}@Overridepublic void onLoading(long total, long current, boolean isUploading) {if (isUploading) {testTextView.setText("upload: " + current + "/" + total);} else {testTextView.setText("reply: " + current + "/" + total);}}@Overridepublic void onSuccess(ResponseInfo<String> responseInfo) {testTextView.setText("reply: " + responseInfo.result);}@Overridepublic void onFailure(HttpException error, String msg) {testTextView.setText(error.getExceptionCode() + ":" + msg);} });

    使用HttpUtils下載文件:

    • 支持?jǐn)帱c(diǎn)續(xù)傳,隨時(shí)停止下載任務(wù),開始任務(wù)
    HttpUtils http = new HttpUtils(); HttpHandler handler = http.download("http://apache.dataguru.cn/httpcomponents/httpclient/source/httpcomponents-client-4.2.5-src.zip","/sdcard/httpcomponents-client-4.2.5-src.zip",true, // 如果目標(biāo)文件存在,接著未完成的部分繼續(xù)下載。服務(wù)器不支持RANGE時(shí)將從新下載。true, // 如果從請(qǐng)求返回信息中獲取到文件名,下載完成后自動(dòng)重命名。new RequestCallBack<File>() {@Overridepublic void onStart() {testTextView.setText("conn...");}@Overridepublic void onLoading(long total, long current, boolean isUploading) {testTextView.setText(current + "/" + total);}@Overridepublic void onSuccess(ResponseInfo<File> responseInfo) {testTextView.setText("downloaded:" + responseInfo.result.getPath());}@Overridepublic void onFailure(HttpException error, String msg) {testTextView.setText(msg);} });... //調(diào)用cancel()方法停止下載 handler.cancel();

    BitmapUtils 使用方法

    BitmapUtils bitmapUtils = new BitmapUtils(this);// 加載網(wǎng)絡(luò)圖片 bitmapUtils.display(testImageView, "http://bbs.lidroid.com/static/image/common/logo.png");// 加載本地圖片(路徑以/開頭, 絕對(duì)路徑) bitmapUtils.display(testImageView, "/sdcard/test.jpg");// 加載assets中的圖片(路徑以assets開頭) bitmapUtils.display(testImageView, "assets/img/wallpaper.jpg");// 使用ListView等容器展示圖片時(shí)可通過PauseOnScrollListener控制滑動(dòng)和快速滑動(dòng)過程中時(shí)候暫停加載圖片 listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true)); listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true, customListener));

    輸出日志 LogUtils

    // 自動(dòng)添加TAG,格式: className.methodName(L:lineNumber) // 可設(shè)置全局的LogUtils.allowD = false,LogUtils.allowI = false...,控制是否輸出log。 // 自定義log輸出LogUtils.customLogger = new xxxLogger(); LogUtils.d("wyouflf");
