完全註解方式就可以進行UI綁定和事件綁定。無需findViewById和setClickListener等。// xUtils的view註解要求必須提供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// 支援綁定多個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})// 更多事件支援參見ViewCommonEventListener類和包com.lidroid.xutils.view.annotation.event。@OnClick(R.id.test_button)public void testButtonClick(View v) { // 方法簽名必須和介面中的要求一致 ...}...//在Activity中注入:@Overridepublic 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:@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.bitmap_fragment, container, false); // 載入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(){ @Override public void onLoading(long total, long current, boolean isUploading) { testTextView.setText(current + / + total); } @Override public void onSuccess(ResponseInfo responseInfo) { textView.setText(responseInfo.result); } @Override public void onStart() { } @Override public void onFailure(HttpException error, String msg) { }});使用HttpUtils上傳檔案 或者 提交資料 到伺服器(post方法)RequestParams params = new RequestParams();params.addHeader(name, value);params.addQueryStringParameter(name, value);// 只包含字串參數時預設使用BodyParamsEntity,// 類似於UrlEncodedFormEntity(application/x-www-form-urlencoded)。params.addBodyParameter(name, value);// 加入檔案參數後預設使用MultipartEntity(multipart/form-data),// 如需multipart/related,xUtils中提供的MultipartEntity支援設定subType為related。// 使用params.setBodyEntity(httpEntity)可設定更多類型的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() { @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 responseInfo) { testTextView.setText(reply: + responseInfo.result); } @Override public void onFailure(HttpException error, String msg) { testTextView.setText(error.getExceptionCode() + : + msg); }});使用HttpUtils下載檔案:
- 支援斷點續傳,隨時停止下載任務,開始任務
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, // 如果目標檔案存在,接著未完成的部分繼續下載。伺服器不支援RANGE時將從新下載。 true, // 如果從請求返回資訊中擷取到檔案名稱,下載完成後自動重新命名。 new RequestCallBack() { @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 responseInfo) { testTextView.setText(downloaded: + responseInfo.result.getPath()); } @Override public void onFailure(HttpException error, String msg) { testTextView.setText(msg); }});...//調用cancel()方法停止下載handler.cancel();BitmapUtils 使用方法BitmapUtils bitmapUtils = new BitmapUtils(this);// 載入網狀圖片bitmapUtils.display(testImageView, http://bbs.lidroid.com/static/image/common/logo.png);// 載入本地圖片(路徑以/開頭, 絕對路徑)bitmapUtils.display(testImageView, /sdcard/test.jpg);// 載入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載入圖片listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true));listView.setOnScrollListener(new PauseOnScrollListener(bitmapUtils, false, true, customListener));
輸出日誌 LogUtils// 自動添加TAG,格式: className.methodName(L:lineNumber)// 可設定全域的LogUtils.allowD = false,LogUtils.allowI = false...,控制是否輸出log。// 自訂log輸出LogUtils.customLogger = new xxxLogger();LogUtils.d(wyouflf);
執行個體,BitmapUtils:
public class xUtilsImageLoader {//架構裡面設定了緩衝和非同步作業,不用單獨設定線程池和緩衝機制(也可以自訂緩衝路徑) 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);//預設背景圖片 bitmapUtils.configDefaultLoadFailedImage(R.drawable.logo_new);//載入失敗圖片 bitmapUtils.configDefaultBitmapConfig(Bitmap.Config.RGB_565);//設定圖片壓縮類型 } /** * * @author sunglasses * @category 圖片回呼函數 */ public class CustomBitmapLoadCallBack extends DefaultBitmapLoadCallBack { @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 圖片載入效果 * @param imageView * @param bitmap */ private void fadeInDisplay(ImageView imageView, Bitmap bitmap) {//目前流行的漸層效果 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){//外部介面函數 bitmapUtils.display(container, url,new CustomBitmapLoadCallBack()); } }
執行個體:HttpGet:
public class xUtilsGet {//自動實現非同步處理,自己不用處理 public void getJson(String url,RequestParams params,final IOAuthCallBack iOAuthCallBack){ HttpUtils http = new HttpUtils(); http.configCurrentHttpCacheExpiry(1000 * 10);//設定逾時時間 http.send(HttpMethod.GET, url, params, new RequestCallBack() {//介面回調 @Override public void onFailure(HttpException arg0, String arg1) { // TODO Auto-generated method stub } @Override public void onSuccess(ResponseInfo info) { // TODO Auto-generated method stub iOAuthCallBack.getIOAuthCallBack(info.result);//利用介面回調資料轉送 } }); } public void getCataJson(int cityId,IOAuthCallBack iOAuthCallBack) {//外部介面函數 String url = http://xxxxxxxxxx; RequestParams params = new RequestParams(); params.addQueryStringParameter(currentCityId, cityId+); getJson(url,params,iOAuthCallBack); } }
執行個體:HttpPost(和HttpGet類似):
public class xUtilsPost {//自動實現非同步處理 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() { @Override public void onFailure(HttpException arg0, String arg1) { // TODO Auto-generated method stub } @Override public void onSuccess(ResponseInfo 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); } }
