Android封装常用工具类的示例详解

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_DIR
if (!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
/**

CORE_POOL_SIZE, MAXIMUM_POOL_SIZE, KEEP_ALIVE_SECONDS, unit,
sPoolWorkQueue, sThreadFactory,new RejectedHandler()){
@Override
public 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 {
@Override
public 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
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
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() {
@Override
public void run() {
//异步操作
}
});

封装
TrustAllCerts类 在OkGo中 。
private static String okhttp(String method , String json){

.sslSocketFactory(TrustAllCerts.createSSLSocketFactory()) //绕过https
.hostnameVerifier(new TrustAllCerts.TrustAllHostnameVerifier()) //绕过https

.url( getIP()+method )
.post(body)

return Objects.requireNonNull(response.body()).string();
}catch (Exception e){
MyLog.e("mylog","error:
"+e.getMessage());
return "error:
"+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());
下载
/**
*

* @param saveFilePath 保存路径
* @param saveName 保存文件名 ，如 XXX.apk
* @param progress 回调函数，获取下载进度
