我用它来检查蓝牙的状态。我不知道如何检查当前是否连接到其他设备,但我认为这可能是一个起点。
private void CheckBlueToothState() {
if (bluetoothAdapter == null) {
//stateBluetooth.setText("Bluetooth NOT support");
} else {
if (bluetoothAdapter.isEnabled()) {
if (bluetoothAdapter.isDiscovering()) {
//stateBluetooth.setText("Bluetooth is currently in device discovery process.");
} else {
//stateBluetooth.setText("Bluetooth is Enabled.");
}
} else {
//stateBluetooth.setText("Bluetooth is NOT Enabled!");
Intent enableBtIntent = new Intent(
BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
}
}
