在Android上切换可发现的蓝牙设备

Question

我正在尝试通过复选框找到一种简单的方法来在Android上切换设备蓝牙可发现性。打开它很简单，但如果再次关闭，我没有任何运气。我正在使用一种解决方法，将设备设置为可发现一秒钟（我在stackoverflow上找到的方法），但我需要找到一种正确的方法。

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    // TODO Auto-generated method stub
    if (buttonView.isChecked()) {
            if (mBluetoothAdapter == null) {
                    Toast.makeText(getApplicationContext(),
                                    "No Bluetooth Support", Toast.LENGTH_SHORT).show();
            } else {
                    if (mBluetoothAdapter.isEnabled()) {
                            Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
                            discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);
                            startActivity(discoverableIntent);
                            Toast.makeText(getApplicationContext(), "Device Discoverable", Toast.LENGTH_SHORT).show();
                    }
            }
    } else {
            if (mBluetoothAdapter.isEnabled()) {
                    Intent disablediscoverableIntent = new Intent(
                                    BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
                    disablediscoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 1);
                    startActivity(disablediscoverableIntent);
                    Toast.makeText(getApplicationContext(),
                                    "Discoverable Disabled", Toast.LENGTH_SHORT).show();

            }
    }
