扫描周围蓝牙设备的demo

老规矩。右键取得图片地址，利用下载工具下载这个显示不出来的图片。后缀改为rar即可得到源代码项目。

package zhang.bluetooth;import java.util.Iterator;import java.util.Set;import android.app.Activity;import android.bluetooth.BluetoothAdapter;import android.bluetooth.BluetoothDevice;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.Button;public class BlueTooth extends Activity {private Button button;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        button=(Button)findViewById(R.id.button);        button.setOnClickListener(new Button.OnClickListener(){@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stub//得到bluetoothAdapter对象BluetoothAdapter adapter= BluetoothAdapter.getDefaultAdapter();//判断BluetoothAdapter师傅哦为空，如果为空，则表明没有蓝牙设备if(adapter!=null){System.out.println("本机拥有BlueTooth");//调用isEnable方法，判断当前蓝牙是否可用if(!adapter.isEnabled()){//创建一个intent对象，。该对象用于启动蓝牙Intent intent = new Intent (BluetoothAdapter.ACTION_REQUEST_ENABLE);startActivity(intent);}//得到已经配对的蓝牙适配器对象Set<BluetoothDevice> devices = adapter.getBondedDevices();if(devices.size()>0){for(Iterator<BluetoothDevice> iterator =devices.iterator();iterator.hasNext();){BluetoothDevice bluetoothDevice = (BluetoothDevice) iterator.next();//打印远程蓝牙设备的地址System.out.println(bluetoothDevice.getAddress());}}}else{System.out.println("没有蓝牙设备");}}        });    }}

布局文件就不给了，就一个button

记得配置

 <uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
