java 一个任务需要多个线程按照一定顺序执行,如果执行错误就执行错误函数

    //在一定时间内,等待某个事件//小于currentStatus的标志位都是true,才能继续向下,不然就报错
    // status 状态表,currentStatus 当前线程状态位置,timeout 超时时间,funcSuccess 规定时间内要执行的函数,funcError 超过规定时间后要执行的函数
    void delayRestartBluetooth(boolean[] status, int currentStatus, int timeout,Consumer<String> funcSuccess,Consumer<String> funcError,String funcSuccessStr,String funcErrorStr){
        //延时执行
        Thread workerThead = new Thread() {
            @RequiresApi(api = Build.VERSION_CODES.N)
            public void run() {
                try {
                    //检测,之前的任务是否完成//未完成就一直等待
                    boolean isEnable = false;
                    if(currentStatus==0)isEnable = true;
                    while (isEnable == false){
                        for(int i=0;i<currentStatus;i++){
                            if(status[i]==false){isEnable = false;break;}
                            else {isEnable = true;}
                        }
                    }
                    if(isEnable == true){
                        funcSuccess.accept(funcSuccessStr);
                        status[currentStatus] = true;
                    }

                } catch (Exception e) {
                    status[currentStatus] = false;
                    e.printStackTrace();
                }
            }
        };
        workerThead.start();
        Thread checkThread =  new Thread() {
            @RequiresApi(api = Build.VERSION_CODES.N)
            public void run() {
                boolean isEnable = false;
                int count=10;
                while (isEnable == false && count<timeout){
                    try {
                        sleep(50);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    count += 50;
                    for(int i=0;i<currentStatus+1;i++){
                        if(status[i]==false){isEnable = false;break;}
                        else {isEnable = true;}
                    }
                }
                if(isEnable == false){
                    try {
                        funcError.accept(funcErrorStr);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    workerThead.interrupt();
                }
            }
        };
        checkThread.start();


//        new Handler().postDelayed(()->{ Log.d(TAG, "ceshi,zhe个只会执行1次: "); },timeout);

 

改进方案,每一步只需要一个线程就可以

    //在一定时间内,等待某个事件//小于currentStatus的标志位都是true,才能继续向下,不然就报错
    // status 状态表,currentStatus 当前线程状态位置,timeout 超时时间,funcSuccess 规定时间内要执行的函数,funcError 超过规定时间后要执行的函数
    void delayRestartBluetooth(boolean[] status, int currentStatus, int timeout,Consumer<String> funcSuccess,Consumer<String> funcError,String funcSuccessStr,String funcErrorStr){
        //延时执行
        new Thread() {
            @RequiresApi(api = Build.VERSION_CODES.N)
            public void run() {
                try {
                    //检测,之前的任务是否完成//未完成就一直等待,直到超时
                    boolean isEnable = false;
                    if(currentStatus==0)isEnable = true;
                    int time=10;
                    int timeStep = 50;//时间步长
                    while (isEnable == false && time<timeout){
                        try {
                            sleep(timeStep);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        time += timeStep;
                        for(int i=0;i<currentStatus;i++){
                            if(status[i]==false){isEnable = false;break;}
                            else {isEnable = true;}
                        }
                    }
                    if(isEnable == true){
                        funcSuccess.accept(funcSuccessStr);
                        status[currentStatus] = true;
                    }
                    else {
                        funcError.accept(funcErrorStr);
                        status[currentStatus] = false;
                    }

                } catch (Exception e) {
                    status[currentStatus] = false;
                    e.printStackTrace();
                }
            }
        }.start();

//        new Handler().postDelayed(()->{ Log.d(TAG, "ceshi,zhe个只会执行1次: "); },timeout);
    }

 

 

 

具体的使用案例如下

            boolean[] status = {false};
            Consumer<String> funcError = x ->{};
            Consumer<String> funcSuccess = x -> {
                mBluetoothAdapter.enable();
                while (!mBluetoothAdapter.isEnabled()){     try { sleep(10); } catch (InterruptedException e) { }    }
                try {
                    sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                Intent intent = new Intent("com.TransIP2BLE.broadcast.BLEBlueTooth.message");
                intent.putExtra("msg","bleRestartOK");
                intent.putExtra("message","cmd:upBleRestart,ble restart successful");
                localBroadcastManager.sendBroadcast(intent);
            };

            delayRestartBluetooth(status,0,10000,funcSuccess,funcError,"","");

 

            boolean[] status = {false,false,false};
            Consumer<String> funcError = x ->{};
            Consumer<String> funcSuccess1 = x -> {

                while (mBluetoothAdapter.isEnabled()){     try { sleep(10); } catch (InterruptedException e) { }    }
                try {
                    sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            };
            Consumer<String> funcSuccess2 = x -> {
                mBluetoothAdapter.enable();
                while (!mBluetoothAdapter.isEnabled()){     try { sleep(10); } catch (InterruptedException e) { }    }
                Log.d(TAG, "restartBluetooth: ");
                try {
                    sleep(600);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            };
            Consumer<String> funcSuccess3 = x -> {
                while (!mBluetoothAdapter.isEnabled()){     try { sleep(10); } catch (InterruptedException e) { }    }
                Intent intent = new Intent("com.TransIP2BLE.broadcast.BLEBlueTooth.message");
                intent.putExtra("msg","bleRestartOK");
                intent.putExtra("message","cmd:upBleRestart,ble restart successful");
                localBroadcastManager.sendBroadcast(intent);
                Log.d(TAG, "restartBluetooth: ");
            };

            delayRestartBluetooth(status,0,10000,funcSuccess1,funcError,"","");
            delayRestartBluetooth(status,1,10000,funcSuccess2,funcError,"","");
            delayRestartBluetooth(status,2,10000,funcSuccess3,funcError,"","");
