android 實現藍牙自動配對鏈接

BluetoothConnectActivityReceiver.java:監聽藍牙配對的廣播
 
代碼：
 
package com.imte.Broadcast;
 
import com.imte.utils.ClsUtils;
 import com.itme.ActivityClass.R;
 
import android.bluetooth.BluetoothDevice;
 import android.content.BroadcastReceiver;
 import android.content.Context;
 import android.content.Intent;
 import android.os.Handler;
 import android.util.Log;
 import android.widget.Toast;
 
public class BluetoothConnectActivityReceiver extends BroadcastReceiver {
 
 String strPsw = "123456";
 
 @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);
    try {
     ClsUtils.setPin(btDevice.getClass(), btDevice, strPsw); // 手機和藍牙採集的裝置配對
     ClsUtils.createBond(btDevice.getClass(), btDevice);
     ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);
     Toast.makeText(
       context,
       context.getResources().getString(
         R.string.bluetooth_connect_success),
       Toast.LENGTH_SHORT);
    } catch (Exception e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
 //    Thread thread=new Thread(strPsw);
 //    thread.
    }
   }
 
 }
 }
 

ClsUtils.java?

最後就是MainActivity,用一個按鈕來實現自動配對，代碼以下：
 
package com.itme.ActivityClass;
 
import android.app.Activity;
 import android.bluetooth.BluetoothAdapter;
 import android.bluetooth.BluetoothDevice;
 import android.os.Bundle;
 import android.util.Log;
 import android.view.View;
 import android.view.View.OnClickListener;
 import android.widget.Button;
 
import com.imte.utils.ClsUtils;
 
public class MainActivity extends Activity implements OnClickListener{
     /** Called when the activity is first created. */
  private static BluetoothDevice remoteDevice=null;
  private Button btn_autopair=null;
  final static String ACTION_BLUETOOTHBC="android.bluetooth.device.action.PAIRING_REQUEST";
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         btn_autopair=(Button)findViewById(R.id.btn_autopair);
         btn_autopair.setOnClickListener(this);
     }
     public static boolean pair(String strAddr, String strPsw)
  {
   boolean result = false;
   //藍牙設備適配器
   BluetoothAdapter bluetoothAdapter = BluetoothAdapter
     .getDefaultAdapter();
   //取消發現當前設備的過程
   bluetoothAdapter.cancelDiscovery();
   if (!bluetoothAdapter.isEnabled())
   {
    bluetoothAdapter.enable();
   }
   if (!BluetoothAdapter.checkBluetoothAddress(strAddr))
   { // 檢查藍牙地址是否有效
    Log.d("mylog", "devAdd un effient!");
   }
   //由藍牙設備地址得到另外一藍牙設備對象
   BluetoothDevice device = bluetoothAdapter.getRemoteDevice(strAddr);
   if (device.getBondState() != BluetoothDevice.BOND_BONDED)
   {
    try
    {
     Log.d("mylog", "NOT BOND_BONDED");
     ClsUtils.setPin(device.getClass(), device, strPsw); // 手機和藍牙採集的裝置配對
     ClsUtils.createBond(device.getClass(), device);
 //    ClsUtils.cancelPairingUserInput(device.getClass(), device);
     remoteDevice = device; // 配對完畢就把這個設備對象傳給全局的remoteDevice
     result = true;
    }
    catch (Exception e)
    {
     // TODO Auto-generated catch block
     Log.d("mylog", "setPiN failed!");
     e.printStackTrace();
    } //
 
  }
   else
   {
    Log.d("mylog", "HAS BOND_BONDED");
    try
    {
     //ClsUtils這個類的的如下靜態方法都是經過反射機制獲得須要的方法
     ClsUtils.createBond(device.getClass(), device);//建立綁定
     ClsUtils.setPin(device.getClass(), device, strPsw); // 手機和藍牙的裝置配對
     ClsUtils.createBond(device.getClass(), device);
 //    ClsUtils.cancelPairingUserInput(device.getClass(), device);
     remoteDevice = device; // 若是綁定成功，就直接把這個設備對象傳給全局的remoteDevice
     result = true;
    }
    catch (Exception e)
    {
     // TODO Auto-generated catch block
     Log.d("mylog", "setPiN failed!");
     e.printStackTrace();
    }
   }
   return result;
  }
  @Override
  public void onClick(View v) {
   // TODO Auto-generated method stub
   switch (v.getId()) {
   case R.id.btn_autopair:
    if (pair("94:DB:46:2B:A1:82", "123456")) {//pair的第一個參數是要配對的藍牙地址，第二個參數是配對時預先設置的密鑰
 
    Log.i("aaron", remoteDevice.getAddress());
    }
    break;
 
  default:
    break;
   }
  }
 }
 
叮咚..如題的功能就實現了。。。
