xUtils简介
DbUtils模块
ViewUtils模块
HttpUtils模块
BitmapUtils模块
使用xUtils快速开发框架需要有以下权限: <uses-permission Android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
混淆时注意事项:
DbUtils使用方法
DbUtils db = DbUtils.create(this); User user = new User(); //这里需要注意的是User对象必须有id属性,或者有通过@ID注解的属性 user.setEmail("wyouflf@qq.com"); user.setName("wyouflf"); db.save(user); // 使用saveBindingId保存实体时会为实体的id赋值 ... // 查找 Parent entity = db.findById(Parent.class, parent.getId()); List<Parent> list = db.findAll(Parent.class);//通过类型查找 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为"in"时,最后一个参数必须是数组或Iterable的实现类(例如List等) Parent test = db.findFirst(Selector.from(Parent.class).where("id", "in", new int[]{1, 2, 3})); // op为"between"时,最后一个参数必须是数组或Iterable的实现类(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); // 自定义sql查询 db.execNonQuery(sql) // 执行自定义sql ...
ViewUtils使用方法
// xUtils的view注解要求必须提供id,以使代码混淆不受影响。 @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绑定事件的方式,使用id绑定不受混淆影响 // 支持绑定多个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}) // 更多事件支持参见ViewCommonEventListener类和包com.lidroid.xutils.view.annotation.event。 @OnClick(R.id.test_button) public void testButtonClick(View v) { // 方法签名必须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); // 加载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 ... } // 其他重载 // 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>(){ @Override public void onLoading(long total, long current, boolean isUploading) { testTextView.setText(current + "/" + total); } @Override public void onSuccess(ResponseInfo<String> responseInfo) { textView.setText(responseInfo.result); } @Override public void onStart() { } @Override public void onFailure(HttpException error, String msg) { } });
使用HttpUtils上传文件 或者 提交数据 到服务器(post方法)
RequestParams params = new RequestParams(); params.addHeader("name", "value"); params.addQueryStringParameter("name", "value"); // 只包含字符串参数时默认使用BodyParamsEntity, // 类似于UrlEncodedFormEntity("application/x-www-form-urlencoded")。 params.addBodyParameter("name", "value"); // 加入文件参数后默认使用MultipartEntity("multipart/form-data"), // 如需"multipart/related",xUtils中提供的MultipartEntity支持设置subType为"related"。 // 使用params.setBodyEntity(httpEntity)可设置更多类型的HttpEntity(如: // MultipartEntity,BodyParamsEntity,FileUploadEntity,InputStreamUploadEntity,StringEntity)。 // 例如发送json参数: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>() { @Override public void onStart() { testTextView.setText("conn..."); } @Override public void onLoading(long total, long current, boolean isUploading) { if (isUploading) { testTextView.setText("upload: " + current + "/" + total); } else { testTextView.setText("reply: " + current + "/" + total); } } @Override public void onSuccess(ResponseInfo<String> responseInfo) { testTextView.setText("reply: " + responseInfo.result); } @Override public void onFailure(HttpException error, String msg) { testTextView.setText(error.getExceptionCode() + ":" + msg); } });
使用HttpUtils下载文件
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, // 如果目标文件存在,接着未完成的部分继续下载。服务器不支持RANGE时将从新下载。 true, // 如果从请求返回信息中获取到文件名,下载完成后自动重命名。 new RequestCallBack<File>() { @Override public void onStart() { testTextView.setText("conn..."); } @Override public void onLoading(long total, long current, boolean isUploading) { testTextView.setText(current + "/" + total); } @Override public void onSuccess(ResponseInfo<File> responseInfo) { testTextView.setText("downloaded:" + responseInfo.result.getPath()); } @Override public void onFailure(HttpException error, String msg) { testTextView.setText(msg); } }); ... //调用cancel()方法停止下载 handler.cancel();
BitmapUtils 使用方法
BitmapUtils bitmapUtils = new BitmapUtils(this); // 加载网络图片 bitmapUtils.display(testImageView, "http://bbs.lidroid.com/static/image/common/logo.png"); // 加载本地图片(路径以/开头, 绝对路径) bitmapUtils.display(testImageView, "/sdcard/test.jpg"); // 加载assets中的图片(路径以assets开头) bitmapUtils.display(testImageView, "assets/img/wallpaper.jpg"); // 使用ListView等容器展示图片时可通过PauseOnScrollListener控制滑动和快速滑动过程中时候暂停加载图片 listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true)); listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true, customListener));
实例BitmapUtils
public class xUtilsImageLoader {//框架里面设置了缓存和异步操作,不用单独设置线程池和缓存机制(也可以自定义缓存路径) private BitmapUtils bitmapUtils; private Context mContext; public xUtilsImageLoader(Context context) { // TODO Auto-generated constructor stub this.mContext = context; bitmapUtils = new BitmapUtils(mContext); bitmapUtils.configDefaultLoadingImage(R.drawable.logo_new);//默认背景图片 bitmapUtils.configDefaultLoadFailedImage(R.drawable.logo_new);//加载失败图片 bitmapUtils.configDefaultBitmapConfig(Bitmap.Config.RGB_565);//设置图片压缩类型 } /** * * @author sunglasses * @category 图片回调函数 */ public class CustomBitmapLoadCallBack extends DefaultBitmapLoadCallBack<ImageView> { @Override public void onLoading(ImageView container, String uri, BitmapDisplayConfig config, long total, long current) { } @Override public void onLoadCompleted(ImageView container, String uri, Bitmap bitmap, BitmapDisplayConfig config, BitmapLoadFrom from) { // super.onLoadCompleted(container, uri, bitmap, config, from); fadeInDisplay(container, bitmap); } @Override public void onLoadFailed(ImageView container, String uri, Drawable drawable) { // TODO Auto-generated method stub } } private static final ColorDrawable TRANSPARENT_DRAWABLE = new ColorDrawable( android.R.color.transparent); /** * @author sunglasses * @category 图片加载效果 * @param imageView * @param bitmap */ private void fadeInDisplay(ImageView imageView, Bitmap bitmap) {//目前流行的渐变效果 final TransitionDrawable transitionDrawable = new TransitionDrawable( new Drawable[] { TRANSPARENT_DRAWABLE, new BitmapDrawable(imageView.getResources(), bitmap) }); imageView.setImageDrawable(transitionDrawable); transitionDrawable.startTransition(500); } public void display(ImageView container,String url){//外部接口函数 bitmapUtils.display(container, url,new CustomBitmapLoadCallBack()); } }
实例HttpGet
public class xUtilsGet {//自动实现异步处理,自己不用处理 public void getJson(String url,RequestParams params,final IOAuthCallBack iOAuthCallBack){ HttpUtils http = new HttpUtils(); http.configCurrentHttpCacheExpiry(1000 * 10);//设置超时时间 http.send(HttpMethod.GET, url, params, new RequestCallBack<String>() {//接口回调 @Override public void onFailure(HttpException arg0, String arg1) { // TODO Auto-generated method stub } @Override public void onSuccess(ResponseInfo<String> info) { // TODO Auto-generated method stub iOAuthCallBack.getIOAuthCallBack(info.result);//利用接口回调数据传输 } }); } public void getCataJson(int cityId,IOAuthCallBack iOAuthCallBack) {//外部接口函数 String url = "http://xxxxxxxxxx"; RequestParams params = new RequestParams(); params.addQueryStringParameter("currentCityId", cityId+""); getJson(url,params,iOAuthCallBack); } }
实例HttpPost(和HttpGet类似)
public class xUtilsPost {//自动实现异步处理 public void doPost(String url, RequestParams params, final IOAuthCallBack iOAuthCallBack) { HttpUtils http = new HttpUtils(); http.configCurrentHttpCacheExpiry(1000 * 10); http.send(HttpMethod.POST, url, params, new RequestCallBack<String>() { @Override public void onFailure(HttpException arg0, String arg1) { // TODO Auto-generated method stub } @Override public void onSuccess(ResponseInfo<String> info) { // TODO Auto-generated method stub iOAuthCallBack.getIOAuthCallBack(info.result); } }); } public void doPostLogin(int cityId, IOAuthCallBack iOAuthCallBack) { String url = "http://xxxxxxxxxxxx"; RequestParams params = new RequestParams(); params.addQueryStringParameter("currentCityId", cityId + ""); params.addBodyParameter("path", "/apps/postCatch"); doPost(url, params, iOAuthCallBack); } }
