Android 封装的工具类

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)*/

使用

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

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());
