android設置gps自動開啓

1.第一種方法

private void toggleGPS() {
        Intent gpsIntent = new Intent();
        gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
        gpsIntent.addCategory("android.intent.category.ALTERNATIVE");
        gpsIntent.setData(Uri.parse("custom:3"));
        try 	{
             PendingIntent.getBroadcast(StartActivity.this, 0, gpsIntent, 0).send();
        } catch (CanceledException e) 	{
              e.printStackTrace();
        }
}

  

2.第二種方法
   

private void openGPSSettings() {       
       //獲取GPS現在的狀態（打開或是關閉狀態）
     boolean gpsEnabled = Settings.Secure.isLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER );
  
     if(gpsEnabled)
     {
	//關閉GPS
      	Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, false );
     }
     else
     {
      	//打開GPS  www.2cto.com
     	 Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, true);

    }

    
  3.第三種方法（手動設置）

     

	LocationManager alm = (LocationManager)StartActivity.this.getSystemService(Context.LOCATION_SERVICE);       
	if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER))
        {           
         	Toast.makeText(this, "GPS模塊正常", Toast.LENGTH_SHORT).show();
        }       
       
        Toast.makeText(this, "請開啓GPS！", Toast.LENGTH_SHORT).show();
        Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);
        startActivityForResult(intent,0); //此爲設置完成後返回到獲取界面  

    
  第一第二種需要加上權限

  <!--允許程序讀取或寫入系統設置 -->
 <uses-permission android:name="android.permission.WRITE_SETTINGS" ></uses-permission>
 <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
