通过编程来开启或关闭主页上的开关

在android的设置中就可以进行更改GPS、网络连接、WIFI、同步等开关，他们是如何是如何实现的呢？

 

 

 

 

开关枚举值：

替换下面代码中custom中的内容。

  private static final int BUTTON_BLUETOOTH = 4;
  private static final int BUTTON_BRIGHTNESS = 1;
  private static final int BUTTON_GPS = 3;
  private static final int BUTTON_SYNC = 2;
  private static final int BUTTON_WIFI = 0;

控制开关代码

 

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:2"));
        try {
            PendingIntent.getBroadcast(this, 0, gpsIntent, 0).send();
        }
        catch (CanceledException e) {
            e.printStackTrace();
        }
