android - 将数据从 Activity 发送到 AccessibilityService android
问题描述
我尝试将数据从 Activity 发送到 AccessibilityService。我找到了解决方案1 2但它不起作用。这是我使用时的代码2：
Activity这是my intent
private fun getAccessibilityServiceIntent(): Intent? {
val mBundle = Bundle()
mBundle.putString("thoigian", thoigian);
val intent = Intent(this@MainActivity, TestAccessibleService::class.java)
intent.putExtras(mBundle)
return intent
}
满的AccessibilityService.java

封装AccessibilityService.java我从以下位置接收数据：
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
Bundle extras = intent.getExtras();
parameter = extras.getString("thoigian");
foo = Integer.parseInt(parameter);
Calendar calendar = Calendar.getInstance();
dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK);
hethan= foo+dayOfWeek;
Log.d("ddddddd0","================="+parameter+"xxx"+hethan);
没有Log.d返回和parameter=null。我哪里做错了？请帮助我，非常感谢。
解决方案
回答：
您可以使用Common类的概念。只需创建一个名为 common 的类：
Public class Common{
public static String thoigian;
}
并在活动中将值设置为该变量：
Common.thoigian ="YOUR_VALUE";
现在，在服务类中，只需Common.thoigian在需要的地方使用
随意询问是否有不清楚的地方。
