1.	 LocationManager locationManager=(LocationManager) getSystemService(Context.LOCATION_SERVICE);       
    2.	         
    3.	        boolean isEnabled= locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);  
    4.	        if(!isEnabled){  
    5.	            //这段代码可以实现GPS开关状态的切换   
    6.	                Intent GPSIntent = new Intent();  
    7.	                GPSIntent.setClassName("com.android.settings",  
    8.	                        "com.android.settings.widget.SettingsAppWidgetProvider");  
    9.	                GPSIntent.addCategory("android.intent.category.ALTERNATIVE");  
    10.	                GPSIntent.setData(Uri.parse("custom:3"));  
    11.	                try {  
    12.	                    PendingIntent.getBroadcast(MainActivity.this, 0, GPSIntent, 0).send();  
    13.	                } catch (CanceledException e) {  
    14.	                    e.printStackTrace();  
    15.	                }      
    16.	//              Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, true);  
    
    注释掉的代码,表面上看可以简单的实现开启GPS功能,但是运行后发现后没有权限,即使加了权限依旧提示permission denied 
    PS：权限都有已经有说明的
    <uses-permission android:name="android.permission.WRITE_SETTINGS" ></uses-permission>
    <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" ></uses-permission>
    Android 在程序中开启网络功能
    	/**   
    	 * 移动网络开关   
    	 */   
        public Object invokeBooleanArgMethod(String methodName,
                   boolean value) throws Exception {
        	   mConnectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
               Class ownerClass = mConnectivityManager.getClass();
               Class[]  argsClass = new Class[1];
                   argsClass[0] = boolean.class;
               Method method = ownerClass.getMethod(methodName,argsClass);
               return method.invoke(mConnectivityManager, value);
           }
        //判断移动网络
        public boolean isNetworkConnected(Context context) {  
        	      if (context != null) {  
        	          ConnectivityManager mConnectivityManager = (ConnectivityManager) context  
        	                  .getSystemService(Context.CONNECTIVITY_SERVICE);  
        	          NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();  
        	          if (mNetworkInfo != null) {  
        	             return mNetworkInfo.isAvailable();  
        	          }  
        	     }  
        	     return false;
        }
