如何实现android蓝牙开发 自动配对连接，并不弹出提示框~
android蓝牙自动配对连接的具体代码如下：
1. 获取蓝牙适配器BluetoothAdapter blueadapter=BluetoothAdapter.getDefaultAdapter();
如果BluetoothAdapter 为null，说明android手机没有蓝牙模块。
2. 判断蓝牙模块是否开启，blueadapter.isEnabled() true表示已经开启，false表示蓝牙并没启用。
3. 启动配置蓝牙可见模式，即进入可配对模式Intent in=new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
in.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 200);
startActivity(in); ，200就表示200秒。
4. 获取蓝牙适配器中已经配对的设备Set device=blueadapter.getBondedDevices();
当然，还需要在androidManifest.xml中声明蓝牙的权限
5.自动配对设置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.开始配对请求
static public boolean createBond(Class btClass, BluetoothDevice device) throws Exception {
Method createBondMethod = btClass.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(device);
return returnValue.booleanValue();
}
