android usb软件自动安装监控,Android中监控USB的插拔

一、需求

在Android应该开发过程中，用到了USB通讯，需要应用监控USB设备的插入和拔出，从而刷新USB设备列表。

二、实现

在使用时，需要register和unregister。

public class USBBroadcastReceiver extends BroadcastReceiver {

private OnUsbListener usbListener;

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (UsbManager.ACTION_USB_DEVICE_DETACHED.equals(action) ||

UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) {

usbListener.onStateChanged();

}

}

public void registerUsbReceiver(Context context) {

IntentFilter filter = new IntentFilter();

filter.addAction(UsbManager.ACTION_USB_DEVICE_ATTACHED);

filter.addAction(UsbManager.ACTION_USB_DEVICE_DETACHED);

context.registerReceiver(this, filter);

}

public void unregisterUsbReceiver(Context context) {

context.unregisterReceiver(this);

}

public void setUsbListener(OnUsbListener usbListener) {

this.usbListener = usbListener;

}

@FunctionalInterface

public interface OnUsbListener {

void onStateChanged();

}

}
