如何解决在 Android 无障碍服务中循环
我正在尝试循环执行一些辅助功能任务。
我有一个全局变量 isProcessInit，默认情况下为 false，当我从 MainActivity 按下 Start 按钮时，我将其设置为 true。
这部分工作正常，但是当我运行 100 次循环时，它会不停地运行到 100 次。 我的意图函数 sendWa() 连续调用 100 次，而没有完成其余的辅助功能点击任务。
我尝试在类似于下面的协程中运行：
runBlocking {
Coroutinescope(Main).launch {
(1..100).forEach {
//My loop tasks here
}
}
}
但与其他问题（例如事件有时会变为空）的相同问题。
这是我完整的无障碍服务：
class AccessibilityService : AccessibilityService() {
private val TAG = "AccessibilityServ"
//private var job: Job = Job()
@RequiresApi(Build.VERSION_CODES.N)

swipePath.moveto(x,y)
swipePath.lineto(x,y)
val gestureBuilder = GestureDescription.Builder()
gestureBuilder.addstroke(strokeDescription(swipePath,50))
dispatchGesture(gestureBuilder.build(),null,null)
}
private fun sudoTap(x: String,y: String) {
runSudoCommand("input tap $x $y")

packageManager.getActivityInfo(componentName,0)

}
有没有办法处理这个事件，只有在完成任务后才能再次运行循环..
提前致谢。
