如何實現Android藍牙開發 自動配對連接,并不彈出提示框

之前做一個android版的藍牙，遇到最大的難題就是自動配對.

上網查資料說是用反射createBond（）和setPin（），但測試時進行配對還是會出現提示，但配對是成功了

我就開始查找怎么關閉這個藍牙配對提示框，后面還是偉大的android源碼幫助了我。

在源碼 BluetoothDevice 類中還有兩個隱藏方法

cancelBondProcess（）和cancelPairingUserInput（）

這兩個方法一個是取消配對進程一個是取消用戶輸入

下面是自動配對的代碼

Mainfest,xml注冊

<receiver android:name=".BluetoothConnectActivityReceiver" >
    <intent-filter>
        <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
    </intent-filter>
</receiver> 自己在收到廣播時處理并將預先輸入的密碼設置進去 

public class BluetoothConnectActivityReceiver extends BroadcastReceiver
{

    String strPsw = "0";

    @Override
    public void onReceive(Context context, Intent intent)
    {
        // TODO Auto-generated method stub
        if (intent.getAction().equals(
                "android.bluetooth.device.action.PAIRING_REQUEST"))
        {
            BluetoothDevice btDevice = intent
                    .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

            // byte[] pinBytes = BluetoothDevice.convertPinToBytes("1234");
            // device.setPin(pinBytes);
            Log.i("tag11111", "ddd");
            try
            {
                ClsUtils.setPin(btDevice.getClass(), btDevice, strPsw); // 手機和藍牙采集器配對
                ClsUtils.createBond(btDevice.getClass(), btDevice);
                ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);
            }
            catch (Exception e)
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }


    }
}
