日志封装类-MyLog

是对android log的封装，封装后 可以设置显示级别

/*** Log的封装类，方便开启和关闭log*/
public class MyLog {public static final int VERBOSE = 1;public static final int DEBUG = 2;public static final int INFO = 3;public static final int WARN = 4;public static final int ERROR = 5;public static final int NOTHING = 6;public static final int level = VERBOSE; //设置显示级别public static final String MYLOG_PATH_SDCARD_DIR = "/sdcard/ScanZbar/log";// 日志文件在sdcard中的路径public static final String MY_LOG_FILE_NAME = "Log.txt";// 本类输出的日志文件名称public static void v(String tag, String msg){if(level <= VERBOSE)Log.v(tag,msg);}public static void d(String tag, String msg){if(level <= DEBUG)Log.d(tag,msg);}public static void i(String tag, String msg){if(level <= INFO)Log.i(tag,msg);}public static void w(String tag, String msg){if(level <= WARN)Log.w(tag,msg);}public static void e(String tag, String msg){if(level <= ERROR)Log.e(tag,msg);}//调用该方法，可以将日志写入日志文件public static void Loge(String tag, String msg){if(LEVEL <= ERROR) {Log.e(tag, msg);writeLogtoFile("ERROR",tag,msg);}}/*** 打开日志文件并写入日志* @param mylogtype* @param tag* @param text*/private static void writeLogtoFile(String mylogtype, String tag, String text) {// 新建或打开日志文件Date nowtime = new Date();String needWriteFiel = new SimpleDateFormat(TimeUtil.SDF3).format(nowtime);String needWriteMessage = new SimpleDateFormat(TimeUtil.SDF1).format(nowtime) + " " + mylogtype + " " + tag + " " + text;File dirPath = Environment.getExternalStorageDirectory();File dirsFile = new File(MYLOG_PATH_SDCARD_DIR);if (!dirsFile.exists()){dirsFile.mkdirs();}//创建日志文件File file = new File(dirsFile.toString(), needWriteFiel +".txt");// MYLOG_PATH_SDCARD_DIRif (!file.exists()) {try {//在指定的文件夹中创建文件boolean creatB = file.createNewFile();if(!creatB)MyLog.e("mylog","创建日志文件失败！");} catch (Exception e) {e.printStackTrace();}}try(FileWriter filerWriter = new FileWriter(file, true);// 后面这个参数代表是不是要接上文件中原来的数据，不进行覆盖BufferedWriter bufWriter = new BufferedWriter(filerWriter)) {bufWriter.write(needWriteMessage);bufWriter.newLine();} catch (IOException e) {e.printStackTrace();}}}

使用
使用和正常log使用一样

MyLog.e("mylog","123");
MyLog.i("mylog","222");
...

线程封装类-LocalThreadPools

针对AsyncTask被弃用的替代

/*** @Description TODO(全局使用的线程池)*/
public class LocalThreadPools {private static int threadNum = 0;private static String TAG = LocalThreadPools.class.getSimpleName();private static ExecutorService THREAD_POOL_EXECUTOR;/*** CPU数量*/private static final int CPU_COUNT = Runtime.getRuntime().availableProcessors();/*** 线程池数量*/private static final int CORE_POOL_SIZE = Math.max(2, Math.min(CPU_COUNT-1,4));/*** 最大线程数量 = CPU数量*2+1*/private static final int MAXIMUM_POOL_SIZE = CPU_COUNT * 2+1;/*** 等待线程存活时间*/private static final int KEEP_ALIVE_SECONDS = 60;/*** 等待线程存活时间的单位*/private static final TimeUnit unit = TimeUnit.MINUTES;private static final BlockingQueue<Runnable> sPoolWorkQueue = new LinkedBlockingQueue<>(8);/*** 线程工厂*/private static final ThreadFactory sThreadFactory = new ThreadFactory() {private final AtomicInteger mCount = new AtomicInteger(1);public Thread newThread(Runnable r) {threadNum++;MyLog.e("mylog","线程工厂创建一个线程:"+threadNum+","+mCount.getAndIncrement());return new Thread(r, "MangoTask #" + mCount.getAndIncrement());}};private void initThreadPool() {MyLog.e("mylog","core_pool_size:"+CORE_POOL_SIZE+",maximum_pool_size:"+MAXIMUM_POOL_SIZE+"," +"KEEP_ALIVE_SECONDS:"+KEEP_ALIVE_SECONDS+",");ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(CORE_POOL_SIZE, MAXIMUM_POOL_SIZE, KEEP_ALIVE_SECONDS, unit,sPoolWorkQueue, sThreadFactory,new RejectedHandler()){@Overridepublic void execute(Runnable command) {super.execute(command);MyLog.e("mylog","-----------ActiveCount="+getActiveCount());MyLog.e("mylog","-----------PoolSize="+getPoolSize());MyLog.e("mylog","-----------Queue="+getQueue().size());MyLog.e("mylog","-----------finish="+getCompletedTaskCount());}};//允许核心线程空闲超时时被回收threadPoolExecutor.allowCoreThreadTimeOut(true);THREAD_POOL_EXECUTOR = threadPoolExecutor;}private class RejectedHandler implements RejectedExecutionHandler {@Overridepublic void rejectedExecution(Runnable r, ThreadPoolExecutor executor) {//可在这里做一些提示用户的操作Tools.showToast(mContext.get(),"当前执行的任务过多，请稍后再试");}}private WeakReference<Context> mContext;private static LocalThreadPools instance;private LocalThreadPools(Context context){mContext = new WeakReference<>(context);initThreadPool();}public static LocalThreadPools getInstance(Context context){if (instance == null) {instance = new LocalThreadPools(context);}return instance;}public void execute(Runnable command){THREAD_POOL_EXECUTOR.execute(command);}/*** 通过interrupt方法尝试停止正在执行的任务，但是不保证真的终止正在执行的任务* 停止队列中处于等待的任务的执行* 不再接收新的任务* @return 等待执行的任务列表*/public static List<Runnable> shutdownNow(){return THREAD_POOL_EXECUTOR.shutdownNow();}/*** 停止队列中处于等待的任务* 不再接收新的任务* 已经执行的任务会继续执行* 如果任务已经执行完了没有必要再调用这个方法*/public void shutDown(){THREAD_POOL_EXECUTOR.shutdown();sPoolWorkQueue.clear();}}

使用

LocalThreadPools.getInstance((TestActivity) mView).execute(new Runnable() {@Overridepublic void run() {//异步操作}            
});

自定义进度条-LoadProgressbar

自定义进度条

POST请求

        private static void okgoPost(String method, HashMap<String,String> hashMap, OkGoCallback callback){OkGo.<String>post(getIP()+method).params(hashMap).execute(new StringCallback() {@Overridepublic void onSuccess(Response<String> response) {callback.callback(response.body());}});}

下载

     OkGo.<File>get(uploadUrl).tag(this)//.headers("header1", "headerValue1")////.params("param1", "paramValue1")//.execute(new FileCallback(saveFilePath,saveName) {@Overridepublic void onStart(com.lzy.okgo.request.base.Request<File, ? extends com.lzy.okgo.request.base.Request> request) {super.onStart(request);MyLog.e("mylog","开始下载");}@Overridepublic void onSuccess(com.lzy.okgo.model.Response<File> response) {progress.getProgress(100,"success");}@Overridepublic void onError(com.lzy.okgo.model.Response<File> response) {super.onError(response);progress.getProgress(-1,"下载出错！");}@Overridepublic void downloadProgress(com.lzy.okgo.model.Progress pp) {super.downloadProgress(pp);int ppi = (int)(pp.fraction * 100);MyLog.e("mylog","progress:"+ppi);progress.getProgress(ppi,"");}});

网络请求框架-OkHttp

引入包

implementation 'com.squareup.okhttp3:okhttp:4.10.0'

封装
TrustAllCerts类 在OkGo中 。

 private static String okhttp(String method , String json){MyLog.e("mylog-url",getIP()+method);OkHttpClient client = new OkHttpClient.Builder().sslSocketFactory(TrustAllCerts.createSSLSocketFactory()) //绕过https.hostnameVerifier(new TrustAllCerts.TrustAllHostnameVerifier()) //绕过https.build();RequestBody body = RequestBody.create(json, JSON);Request request = new Request.Builder().url( getIP()+method ).post(body).build();try{Response response = client.newCall(request).execute();return Objects.requireNonNull(response.body()).string();}catch (Exception e){MyLog.e("mylog","error:\r\n"+e.getMessage());return "error:\r\n"+e.getMessage();}}

调用

GetList list = new GetList(flightDate,flightNo,sourceAirport, myApplication.getAppIp()); //参数类
//list.toString() 为 类转json字符串
String response = okhttp(GET_LIST,list.toString());
