1.承接上一篇文章，本篇文章主要实现了蓝牙的打开 关闭 允许搜索 查看配对设备
2. BluetoothInit，主要实现了部件的初始化，按钮的点击事件，通过ListVIew显示本地配对的蓝牙设备，ListView的点击事件，弹出对话框，作为客户端连接服务器

} Intent intent = new Intent(BluetoothInit.this,BluetoothChat.class); startActivity(intent); } }); dialog.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { return; } }); dialog.show();//显示 }}3.SearchBluetoothDevice从BluetoothInit的服务端 客户端 跳转的界面，从服务端跳转，本机便作为服务端，客户端如同，此界面会显示当前检测到的所有设备，包括配对的，为配对的，可分别实现配对设配的连接，未配对设备的配对
