如何使蓝牙变得不可发现?

本文介绍了如何使蓝牙变得不可发现?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经学习了使蓝牙在Android中可发现的代码，例如:

I have learned the codes to make blue-tooth discoverable in Android,like:

Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent);` =

那么，如何在发现蓝牙后就立即人工使其无法被发现?

So, how can i make blue-tooth un-discoverable artificially as soon as i make it discoverable?

感谢所有帮助！

推荐答案

我找到了一个方法，尽管我还不了解，但它在我的项目中有效！

I have found a method,although i don't understand it yet,it works in my project!

public void closeDiscoverableTimeout() { BluetoothAdapter adapter=BluetoothAdapter.getDefaultAdapter(); try { Method setDiscoverableTimeout = BluetoothAdapter.class.getMethod("setDiscoverableTimeout", int.class); setDiscoverableTimeout.setAccessible(true); Method setScanMode =BluetoothAdapter.class.getMethod("setScanMode", int.class,int.class); setScanMode.setAccessible(true); setDiscoverableTimeout.invoke(adapter, 1); setScanMode.invoke(adapter, BluetoothAdapter.SCAN_MODE_CONNECTABLE,1); } catch (Exception e) { e.printStackTrace(); } }
