android藍牙自動連接
① 如何實現android藍牙開發 自動配對連接，並不彈出提示框
我就開始查找怎麼關閉這個藍牙配對提示框，後面還是偉大的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
<receiverandroid:name=".">
<intent-filter>
<actionandroid:name="android.bluetooth.device.action.PAIRING_REQUEST"/>
</intent-filter>
</receiver>
自己在收到廣播時處理並將預先輸入的密碼設置進去

StringstrPsw="0";
@Override
publicvoidonReceive(Contextcontext,Intentintent)
{
//TODOAuto-generatedmethodstub
if(intent.getAction().equals(
"android.bluetooth.device.action.PAIRING_REQUEST"))
{
BluetoothDevicebtDevice=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);

② 如何實現android藍牙自動配對連接
android藍牙自動配對連接的具體代碼如下：
1. 獲取藍牙適配器BluetoothAdapter blueadapter=BluetoothAdapter.getDefaultAdapter();
如果BluetoothAdapter 為null，說明android手機沒有藍牙模塊。
2. 判斷藍牙模塊是否開啟，blueadapter.isEnabled() true表示已經開啟，false表示藍牙並沒啟用。
3. 啟動配置藍牙可見模式，即進入可配對模式Intent in=new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
in.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 200);
startActivity(in); ，200就表示200秒。
4. 獲取藍牙適配器中已經配對的設備Set device=blueadapter.getBondedDevices();
當然，還需要在androidManifest.xml中聲明藍牙的許可權5.自動配對設置Pin值
static public boolean autoBond(Class btClass, BluetoothDevice device, String strPin)
throws Exception {
Method autoBondMethod = btClass.getMethod("setPin", new Class[] { byte[].class });
Boolean result = (Boolean) autoBondMethod
.invoke(device, new Object[] { strPin.getBytes() });
return result;
}
6.開始配對請求
static public boolean createBond(Class btClass, BluetoothDevice device) throws Exception {
Method createBondMethod = btClass.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(device);
return returnValue.booleanValue();
}
③ android 手機藍牙怎樣自動連接已配對的設備
藍牙和手機的詳細連接步驟如下：
1,手機打開藍牙功能，進去搜索藍牙耳機狀態。
2,使藍牙耳機在開機狀態，需要長按藍牙耳機的接聽鍵。
3,直到指示燈：藍燈紅燈交替閃爍再松開。
4,這個時候藍牙耳機和手機會再次進入匹對。
5,注意手機和藍牙距離要在10米內。
等手機上面顯示此藍牙型號設備後，點擊確定即可連接使用了。

⑤ android 怎麼實現藍牙的自動匹配和連接
eoe 看到過：
<receiver android:name=".broadcast.PairingRequest">
<intent-filter>
<action android:name="android.bluetooth.device.action.PAIRING_REQUEST" /$amp;>amp;$nbsp;
<action android:name="android.bluetooth.device.action.PAIRING_CANCEL" /$amp;>amp;$nbsp;
</intent-filter>
</receiver>
public class PairingRequest extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent){
if (intent.getAction().equals("ACTION_PAIRING_REQUEST")) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
byte[] pinBytes = BluetoothDevice.convertPinToBytes("1234");
device.setPin(pinBytes);
}
}
}
其中的藍牙BluetoothDevice這個類要用源碼里的替換下（不然會缺少方法）。
⑥ android 藍牙自動配對自動連接 可以實現嗎
android藍牙自動配對連接的具體代碼如下：
1. 獲取藍牙適配器BluetoothAdapter blueadapter=BluetoothAdapter.getDefaultAdapter();
如果BluetoothAdapter 為null，說明android手機沒有藍牙模塊。
2. 判斷藍牙模塊是否開啟，blueadapter.isEnabled() true表示已經開啟，false表示藍牙並沒啟用。
3. 啟動配置藍牙可見模式，即進入可配對模式Intent in=new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
in.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 200);
startActivity(in); ，200就表示200秒。
4. 獲取藍牙適配器中已經配對的設備Set<BluetoothDevice> device=blueadapter.getBondedDevices();
當然，還需要在androidManifest.xml中聲明藍牙的許可權
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
5.自動配對設置Pin值
static public boolean autoBond(Class btClass, BluetoothDevice device, String strPin)
throws Exception {
Method autoBondMethod = btClass.getMethod("setPin", new Class[] { byte[].class });
Boolean result = (Boolean) autoBondMethod
.invoke(device, new Object[] { strPin.getBytes() });
return result;
}
6.開始配對請求
static public boolean createBond(Class btClass, BluetoothDevice device) throws Exception {
Method createBondMethod = btClass.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(device);
return returnValue.booleanValue();
}
⑦ 通過android代碼如何實現手機藍牙自動連接最後一次已配對的設備
先明確場景。你是希望如下哪種自動連接？
case1: 手機開機自動連接藍牙最後配對設備：Android已經在Framework層實現。不需要Apk再做。關鍵代碼如下：
.java 裡面
onReceive 收到事件BluetoothAdapter.STATE_ON後
else if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(action)) {
initiateConnection();給狀態機發CONNECT
.sendMessage(.CONNECT);
case2:藍牙關閉狀態，打開藍牙，自動連接最後使用的設備：Apk層注冊監聽藍牙打開的廣播，然後在事件響應中獲取已配對列表，取第一個去進行連接就好。
注冊監聽藍牙打開的廣播事件：android.bluetooth.adapter.action.STATE_CHANGED
Bluetooth ACTION_STATE_CHANGED curState = 11,preState = 10 打開中
Bluetooth ACTION_STATE_CHANGED curState = 12,preState = 11 打開了。
獲取已配對設備列表：BluetoothAdapter.getBondedDevices()
取出第一個設備(也就是最新的），連接：
framework/base/core/java/android/bluetooth/
BluetoothHeadsetClient: connect(device)
BluetoothA2dpSink: connect(device)

4. 獲取藍牙適配器中已經配對的設備Set<BluetoothDevice> device=blueadapter.getBondedDevices();
當然，還需要在androidManifest.xml中聲明藍牙的許可權
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
5.自動配對設置Pin值
static public boolean autoBond(Class btClass, BluetoothDevice device, String strPin)
throws Exception {
Method autoBondMethod = btClass.getMethod("setPin", new Class[] { byte[].class });
Boolean result = (Boolean) autoBondMethod
.invoke(device, new Object[] { strPin.getBytes() });
return result;
}
6.開始配對請求
static public boolean createBond(Class btClass, BluetoothDevice device) throws Exception {
Method createBondMethod = btClass.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(device);
return returnValue.booleanValue();
}
