android开发|多线程 handler 使用开发语言|java

1.子线程使用handler postdelay；
在主线程里，搞定写数据；
发现，只写密码块不行，必须写了那个前面的，才可以，写后面的；

public void initCardFromNew() { //executorWriteService = Executors.newScheduledThreadPool(4); //executorWriteService.scheduleAtFixedRate(initCardRunable, 20, 60, TimeUnit.MILLISECONDS); //ExecutorService singleThreadExecutor = Executors.newSingleThreadExecutor(); //singleThreadExecutor.execute(initCardRunable); handler.post(initCardRunable); } Handler handler = new Handler(); private Runnable initCardRunable = new Runnable() { @Override public void run() {if (curretnBlock < 64) {sectorIndex = curretnBlock / 4; if (curretnBlock % 4 != 3) { blockInde = curretnBlock % 4; // Log.e("sjt", "写入数据块第" + sectorIndex + "扇区第" + blockInde + "块数据"); onWrite(Constant.Datablock0_2, sectorIndex, blockInde); //写数据块 } else { Log.e("sjt", "写入秘钥块第" + sectorIndex + "扇区第" + 3 + "块数据"); onWrite(Constant.CCKeyAB, sectorIndex, 3); //写密码块 } handler.postDelayed(this, 50); curretnBlock++; } else { curretnBlock = 0; //executorService.shutdown(); //关闭读写 } } };

【android开发|多线程 handler 使用】线程池操作，必须要先写数据块，在写密码块；

public void initCardFromNew() { executorWriteService = Executors.newScheduledThreadPool(15); executorWriteService.scheduleAtFixedRate(initCardRunable, 20, 50, TimeUnit.MILLISECONDS); //ExecutorService singleThreadExecutor = Executors.newSingleThreadExecutor(); //singleThreadExecutor.execute(initCardRunable); // handler.post(initCardRunable); } Handler handler = new Handler(); private Runnable initCardRunable = new Runnable() { @Override public void run() {if (curretnBlock < 64) {sectorIndex = curretnBlock / 4; if (curretnBlock % 4 != 3) { blockInde = curretnBlock % 4; // Log.e("sjt", "写入数据块第" + sectorIndex + "扇区第" + blockInde + "块数据"); onWrite(Constant.Datablock0_2, sectorIndex, blockInde); //写数据块 } else { Log.e("sjt", "写入秘钥块第" + sectorIndex + "扇区第" + 3 + "块数据"); onWrite(Constant.CCKeyAB, sectorIndex, 3); //写密码块 } // handler.postDelayed(this, 50); curretnBlock++; } else { curretnBlock = 0; executorService.shutdown(); //关闭读写 } } };
