java关闭飞行模式代码_我的代码持续切换飞行模式

我有一个屏幕(Activity)可以执行以下操作:它有一个切换按钮,可以切换飞行模式;它是通过使用一个派生出新线程的服务来完成的。它还有一个按钮,以完全相同的方式执行完全相同的操作。下面的代码片段没有什么特别之处。当按键被点击时,切换按钮的一切工作正常(如果手机当前不在飞行模式,则飞行模式变为“开”;如果手机当前处于飞行模式,则变为“关”,飞行模式持续切换(飞行模式从“开”切换到“关”,再切换回“开”,然后切换到“关”…),就好像它陷入了一个循环。在互联网上进行了一些研究后,我怀疑这与Android中手机/服务状态的intent/broadcastReceiver被触发的方式有关;因为toggle按钮有两种状态,有效地防止了意图再次被广播。这是对的吗??如果是,用按钮切换飞行模式的正确方式是什么(相对于单选按钮或切换按钮)?
