如何在安卓上列出所有连接的蓝牙设备?
谢谢!
最佳答案
public void checkConnected()
{
// true == headset connected && connected headset is support hands free
int state = BluetoothAdapter.getDefaultAdapter().getProfileConnectionState(BluetoothProfile.HEADSET);
if (state != BluetoothProfile.STATE_CONNECTED)
return;
try
{
BluetoothAdapter.getDefaultAdapter().getProfileProxy(_context, serviceListener, BluetoothProfile.HEADSET);
}
catch (Exception e)
{
e.printStackTrace();
}
}
private ServiceListener serviceListener = new ServiceListener()
{
@Override
public void onServiceDisconnected(int profile)
{
}
@Override
public void onServiceConnected(int profile, BluetoothProfile proxy)
{
for (BluetoothDevice device : proxy.getConnectedDevices())
{
Log.i("onServiceConnected", "|" + device.getName() + " | " + device.getAddress() + " | " + proxy.getConnectionState(device) + "(connected = "
+ BluetoothProfile.STATE_CONNECTED + ")");
}
BluetoothAdapter.getDefaultAdapter().closeProfileProxy(profile, proxy);
}
};
