蓝牙的简单学习——开/关—搜索

• 1、显式开启蓝牙设备

  view source print ?

  1. Intent intent=new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

  2. startActivityForResult(intent,1);
  2、隐式开启/关闭蓝牙设备
  view source print ?

  1. BluetoothAdapter mAdapter=BluetoothAdapter.getDefaultAdapter();

  2. //开启蓝牙设备

  3. mAdapter.enable();

  4. //关闭蓝牙设备

  5. mAdapter.disable();
  3、获取已配对的蓝牙设备
  view source print ?

  01. Set<BluetoothDevice> mDevices=mAdapter.getBondedDevices();

  02. //获取已配对的设备

  03. if(mDevices.size()>0)

  04. {

  05. for(BluetoothDevice mDevice : mDevices)

  06. {

  07. mView.append(mDevice.getName()+":"+mDevice.getAddress()+"\n");

  08. }

  09. }
  4、搜索蓝牙设备
  view source print ?

  01. private final BroadcastReceiver receiver=new BroadcastReceiver()

  02. {

  03. @Override

  04. public void onReceive(Context mContext, Intent intent)

  05. {

  06. if(BluetoothDevice.ACTION_FOUND.equals(intent.getAction()))

  07. {

  08. BluetoothDevice mDevice=intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

  09. if(mDevice.getBondState()!=BluetoothDevice.BOND_BONDED)

  10. {

  11. mView.append(mDevice.getName()+":"+mDevice.getAddress()+"\n");

  12. }

  13. }elseif(BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(intent.getAction()))

  14. {

  15. MainActivity.this.setProgressBarIndeterminateVisibility(false);

  16. }

  17. }

  18. };

  19.  

  20.  

  21. //蓝牙动作监听广播

  22. IntentFilter mFilter=new IntentFilter(BluetoothDevice.ACTION_FOUND);

  23. this.registerReceiver(receiver, mFilter);

  24. //蓝牙动作监听结束广播

  25. mFilter=new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);

  26. this.registerReceiver(receiver, mFilter);
