Android发现蓝牙永远不可见超时

Question

是否有办法找到蓝牙可见性是否设置为'从不超时'状态?

谢谢。

Answer 1

试试这个，

BluetoothAdapter ba = BluetoothAdapter.getDefaultAdapter();
if (ba.getScanMode() != BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE)
{
    Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
    discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);           
    startActivity(discoverableIntent);
}

你还应该确保适配器是打开的
