为了追踪蓝牙连接状态的变化,我们可以注册一个广播接收器: BroadcastReceiverreceiver=newBroadcastReceiver(){publicvoidonReceive(Contextcontext,Intentintent){finalStringaction=intent.getAction();if(BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)){// 已连接Log.d("BluetoothConnection","设备已连接");}elseif...
这个广播包含了一个EXTRA_STATE额外数据,它的值可以是BluetoothAdapter.STATE_ON(蓝牙已打开)、BluetoothAdapter.STATE_OFF(蓝牙已关闭)或BluetoothAdapter.STATE_TURNING_ON(蓝牙正在打开)等。 3. 在广播接收器中处理蓝牙连接的状态变化 要监听蓝牙设备的连接状态变化,你需要监听BluetoothDevice.ACTION_ACL_CONNECTED(设备...
