android - 如何使用处理程序线程进行多线程

Question

我正在尝试在谷歌地图上移动多个标记，每个标记都在单独的线程中。目前我在循环内使用 java 线程类为每辆车创建单独的线程。这是示例代码:

private void proceedToMoveVehicle(ArrayList<RealTimeDetailsResponce> sourceList, ArrayList<RealTimeDetailsResponce> destinationList) {
    for (int i = 0; i < destinationList.size(); i++) {
        for (int j = 0; j < sourceList.size(); j++) {
            if (destinationList.get(i).getVehicleNo().equalsIgnoreCase(sourceList.get(j).getVehicleNo())) {
                final com.google.maps.model.LatLng vehicleStartPositions = new com.google.maps.model.LatLng(sourceList.get(j).getLatitude(), sourceList.get(j).getLongitude());
                final double destainationLatitude = destinationList.get(i).getLatitude();
                final double destainationLongitude = destinationList.get(i).getLongitude();
                final String vehicleTitle = sourceList.get(j).getVehicleNo();
                final com.google.maps.model.LatLng vehicleEndPositions = new com.google.maps.model.LatLng(destainationLatitude, destainationLongitude);
                final double speedValue = 0.0000;
                if (vehicleStartPositions.lat != vehicleEndPositions.lat || vehicleStartPositions.lng != vehicleEndPositions.lng) {
                    Thread thread = new Thread(new Runnable() {
                        @Override
                        public void run() {
                            getPathyFromDirectionAPiRequestNew(vehicleStartPositions, vehicleEndPositions, vehicleTitle);
                            runOnUiThread(new Runnable() {
                                @Override
                                public void run() {
                                    moveVehicle(vehicleTitle, speedValue);
                                }
                            });
                        }
                    });
                    thread.start();
                }
            }
        }
    }
}

我每 5 秒从服务器获取车辆的更新位置。在这里，缺点是一旦我获得更新的位置，我就无法再次重用这些线程，我必须再次创建一个新线程。

我听说过 android 处理程序线程，因为我们可以使用 Looper 重用线程。有人可以帮助我使用处理程序线程执行此操作。

Answer 1

试试这个:

ExecutorService executorService = Executors.newFixedThreadPool(32); // you can number of threads you want

executorService.execute(new Runnable() {
public void run() {
         //do your work1 here
    } 
});

executorService.execute(new Runnable() {
public void run() {
         //do your work2 here and so on..
    } 
});

或者你可以放一个循环。
