android 蓝牙4.0搜索功能支持所有品牌的手机

一、老的方法：
// 注册广播接收器。
// 接收蓝牙发现

IntentFilter filterFound = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver1, filterFound);

IntentFilter filterStart = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
registerReceiver(mReceiver1, filterStart);

IntentFilter filterFinish = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
registerReceiver(mReceiver1, filterFinish);

if(蓝牙是否连接){
   mBluetoothAdapter.startDiscovery();
}

 

// 广播接收发现蓝牙设备


    private BroadcastReceiver mReceiver1 = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();

            if (BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(action)) {
                LogUtil.it(TAG, "开始扫描...");
            }

            if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                if (device != null) {

                  // 发现蓝牙添加到ListView中

                }
            }

            if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
                LogUtil.it(TAG, "扫描结束.");

                if(没有连接在搜索蓝牙){
                    mScanning2= mBluetoothAdapter.startDiscovery();
                }

            }
        }
    };

//销毁蓝牙搜索。

unregisterReceiver(mReceiver1);

//取消蓝牙搜索。
mBluetoothAdapter.cancelDiscovery();

新的方法：

   //搜索蓝牙方法。

  boolean mScannings =false;

if (是否搜索蓝牙) {
    if (mBluetoothAdapter.isEnabled()) {
 if (mScannings) return;
        mScannings = true;

        mBluetoothAdapter.startLeScan(mLeScanCallbacks);
    }
} else {
    mBluetoothAdapter.stopLeScan(mLeScanCallbacks);
    mScannings = false;
}

 

private BluetoothAdapter.LeScanCallback mLeScanCallbacks = new BluetoothAdapter.LeScanCallback() {
        @Override
        public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord) {
          
            if(是否支持蓝牙的类型)){

             //ListView Item 体现在界面中。
            }

        }
    };
