在android中监听是否点击了Home键，按照以下几步就可以实现：
1、新建一个广播接收者，代码如下：
internal inner class InnerRecevier : BroadcastReceiver() {
val SYSTEM_DIALOG_REASON_KEY = "reason"
val SYSTEM_DIALOG_REASON_HOME_KEY = "homekey"
override fun onReceive(context: Context, intent: Intent) {
val action = intent.action
if (Intent.ACTION_CLOSE_SYSTEM_DIALOGS == action) {
val reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY)
if (reason != null) {
if (reason == SYSTEM_DIALOG_REASON_HOME_KEY) {
Toast.makeText(this@HistoryGameDetailActivity, "点击了Home键",
Toast.LENGTH_SHORT).show()
}
}
}
}
}
2、注册广播：
//创建广播
innerReceiver = InnerRecevier()
//动态注册广播
val intentFilter = IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)
//启动广播
registerReceiver(innerReceiver, intentFilter)
3、最后别忘了取消注册：
if (innerReceiver != null) {
unregisterReceiver(innerReceiver)
}
效果图如下：
