Android判断和监听底座状态和类型的方法介绍

IntentFilter ifilter = new IntentFilter(Intent.ACTION_DOCK_EVENT);
Intent dockStatus = context.registerReceiver(null, ifilter);
//You can extract the current docking status from the EXTRA_DOCK_STATE extra:
 
//int dockState = battery.getIntExtra(EXTRA_DOCK_STATE, -1);
boolean isDocked = dockState != Intent.EXTRA_DOCK_STATE_UNDOCKED;

车载
桌面
Low-End (Analog) Desk(猜是显示模拟时钟)
High-End (Digital) Desk(猜是显示数字时钟)

boolean isCar = dockState == EXTRA_DOCK_STATE_CAR;
boolean isDesk = dockState == EXTRA_DOCK_STATE_DESK ||
                 dockState == EXTRA_DOCK_STATE_LE_DESK ||
                 dockState == EXTRA_DOCK_STATE_HE_DESK;

<action android:name="android.intent.action.ACTION_DOCK_EVENT"/>
