如何實現android藍牙開發 自動配對鏈接,並不彈出提示框 html
以前作一個android版的藍牙,遇到最大的難題就是自動配對.java
上網查資料說是用反射createBond()和setPin(),但測試時進行配對仍是會出現提示,但配對是成功了android
我就開始查找怎麼關閉這個藍牙配對提示框,後面仍是偉大的android源碼幫助了我。git
在源碼 BluetoothDevice 類中還有兩個隱藏方法app
cancelBondProcess()和cancelPairingUserInput()ide
這兩個方法一個是取消配對進程一個是取消用戶輸入函數
下面是自動配對的代碼post
Mainfest,xml註冊測試
<receiver android:name=".BluetoothConnectActivityReceiver" > <intent-filter> <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" /> </intent-filter> </receiver> 本身在收到廣播時處理並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); // 手機和藍牙採集器配對 ClsUtils.createBond(btDevice.getClass(), btDevice); ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }
