Android開發學習之藍芽API

1、顯式開啟藍牙裝置

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

2、隱式開啟/關閉藍牙裝置

BluetoothAdapter mAdapter=BluetoothAdapter.getDefaultAdapter();//開啟藍牙裝置mAdapter.enable();//關閉藍牙裝置mAdapter.disable();

3、擷取已配對的藍牙裝置

Set mDevices=mAdapter.getBondedDevices();//擷取已配對的裝置if(mDevices.size()>0){   for(BluetoothDevice mDevice : mDevices)   {mView.append(mDevice.getName()+":"+mDevice.getAddress()+"\n");   }}

4、搜尋藍牙裝置

private final BroadcastReceiver receiver=new BroadcastReceiver(){    @Override    public void onReceive(Context mContext, Intent intent)     {if(BluetoothDevice.ACTION_FOUND.equals(intent.getAction())){   BluetoothDevice mDevice=intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);   if(mDevice.getBondState()!=BluetoothDevice.BOND_BONDED)   {mView.append(mDevice.getName()+":"+mDevice.getAddress()+"\n");   }}else if(BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(intent.getAction())){MainActivity.this.setProgressBarIndeterminateVisibility(false);}     }};//藍芽動作監聽廣播IntentFilter mFilter=new IntentFilter(BluetoothDevice.ACTION_FOUND);this.registerReceiver(receiver, mFilter);//藍芽動作監聽結束廣播mFilter=new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);this.registerReceiver(receiver, mFilter);
