XUtils是基于afinal開發的,比afinal穩定性提高了不少,下面是介紹:
xUtils簡介
- xUtils 包含了很多實用的android工具。
- xUtils 最初源于Afinal框架,進行了大量重構,使得xUtils支持大文件上傳,更全面的http請求協議支持(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,一行代碼就可以進行增刪改查;
- 支持事務,默認關閉;
- 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(需要混淆的時候請注解表名和列名);
- 支持綁定外鍵,保存實體時外鍵關聯實體自動保存或更新;
- 自動加載外鍵關聯實體,支持延時加載;
- 支持鏈式表達查詢,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com.lidroid.xutils.view.annotation.event。
-
HttpUtils模塊:
- 支持同步,異步方式的請求;
- 支持大文件上傳,上傳大文件不會oom;
- 支持GET,POST,PUT,MOVE,COPY,DELETE,HEAD,OPTIONS,TRACE,CONNECT請求;
- 下載支持301/302重定向,支持設置是否根據Content-Disposition重命名下載的文件;
- 返回文本內容的請求(默認只啟用了GET請求)支持緩存,可設置默認過期時間和針對當前請求的過期時間。
-
BitmapUtils模塊:
- 加載bitmap的時候無需考慮bitmap加載過程中出現的oom和android容器快速滑動時候出現的圖片錯位等現象;
- 支持加載網絡圖片和本地圖片;
- 內存管理使用lru算法,更好的管理bitmap內存;
- 可配置線程加載線程數量,緩存大小,緩存路徑,加載顯示動畫等...
使用xUtils快速開發框架需要有以下權限:
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />混淆時注意事項:
- 添加Android默認混淆配置${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 { *; }
- 對使用DbUtils模塊持久化的實體類不要混淆,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保存實體時會為實體的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,最后一個參數必須是數組或Iterable的實現類(例如List等) Parent test = db.findFirst(Selector.from(Parent.class).where("id", "in", new int[]{1, 2, 3})); // op為"between"時,最后一個參數必須是數組或Iterable的實現類(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) // 執行自定義sql ...ViewUtils使用方法
- 完全注解方式就可以進行UI綁定和事件綁定。
- 無需findViewById和setClickListener等。
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 提交數據 到服務器(post方法)
RequestParams params = new RequestParams(); params.addHeader("name", "value"); params.addQueryStringParameter("name", "value");// 只包含字符串參數時默認使用BodyParamsEntity, // 類似于UrlEncodedFormEntity("application/x-www-form-urlencoded")。 params.addBodyParameter("name", "value");// 加入文件參數后默認使用MultipartEntity("multipart/form-data"), // 如需"multipart/related",xUtils中提供的MultipartEntity支持設置subType為"related"。 // 使用params.setBodyEntity(httpEntity)可設置更多類型的HttpEntity(如: // MultipartEntity,BodyParamsEntity,FileUploadEntity,InputStreamUploadEntity,StringEntity)。 // 例如發送json參數: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:
- 支持斷點續傳,隨時停止下載任務,開始任務
BitmapUtils 使用方法
BitmapUtils bitmapUtils = new BitmapUtils(this);// 加載網絡圖片 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等容器展示圖片時可通過PauseOnScrollListener控制滑動和快速滑動過程中時候暫停加載圖片 listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true)); listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true, customListener));輸出日志 LogUtils
// 自動添加TAG,格式: className.methodName(L:lineNumber) // 可設置全局的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");
