android 藍芽開發之淺入門

本文僅僅給出藍芽開發的一個相當淺顯得列子，喜歡安卓的親們可以照著敲一下，看一下，想一想，更好的更完善的話，小菜鳥推薦親們在讀懂本部落格的列子之後，再去看一看小菜鳥轉載的不錯的博文，地址http://blog.csdn.net/woshishuoshuoa/article/details/9709371~~~誠摯地歡迎大家提出寶貴的建議哦~~~

1，原始碼：

package com.example.com_diecolor_demo13;import java.util.List;import android.net.wifi.WifiConfiguration;import android.net.wifi.WifiInfo;import android.net.wifi.WifiManager;import android.net.wifi.WifiManager.WifiLock;import android.os.Bundle;import android.widget.TextView;import android.widget.Toast;import android.app.Activity;public class MainActivity extends Activity {    TextView textView;    WifiManager wifiManager;    WifiConfiguration wifiConfiguration;    WifiInfo wifiInfo;    WifiLock wifiLock;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);textView=(TextView) findViewById(R.id.tv_main);wifiManager=(WifiManager) getSystemService(WIFI_SERVICE);//獲得wifiManager對象Toast.makeText(this, "wifi狀態："+wifiManager.getWifiState(),3000).show();  if (!wifiManager.isWifiEnabled()) {//wifiManager.isWifiEnabled()判斷wifi是否已經開啟//開啟wifiwifiManager.setWifiEnabled(true);Toast.makeText(this, "wifi當前的狀態："+wifiManager.getWifiState(),3000).show();}List<WifiConfiguration> list=wifiManager.getConfiguredNetworks();//配置好的列表wifiInfo=wifiManager.getConnectionInfo(); //得到串連網路的資訊wifiLock=wifiManager.createWifiLock(1,"laoc");//鎖StringBuffer buffer=new StringBuffer();for(WifiConfiguration wifiConfiguration:list){String tempString="";tempString+="SSID:"+wifiConfiguration.SSID+"\n"+            "NETWORK ID"+intToIp(wifiConfiguration.networkId)+    "preshareKey"+wifiConfiguration.preSharedKey+    "狀態"+wifiConfiguration.status+    "速度："+wifiInfo.getLinkSpeed();buffer.append(tempString);}textView.setText(buffer);}/* * 將int類型的IP地址轉換成4段類型的IP地址 * */  private String intToIp(int ip)  {  return (ip & 0xFF) + "." +((ip>>8) & 0xFF)+"."+((ip>>16) & 0xFF)  +((ip>>24)&0xFF);  }}

在AndroidManifest.xml
