我有一个扩展AccessibilityService的类,当有某个事件开始活动时。
问题是,当活动结束时,它应该将数据发送回' AccessibilityService'。有没有人知道如何做到这一点?
示例:
public class MyAccessibilityService extends AccessibilityService {
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
if (event.getEventType()==AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED){
Intent intent=new Intent(getApplicationContext(),DialogActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
// String resul=set result When Activity is closed
}
}
提前致谢!

AccesibilityService是Service类的继承类。所以我们可以将这个问题提到这个: {{3}}
您问题的最简单方法:
1)在Activity的onDestroy()方法中调用startService():
@Override
protected void onDestroy() {
super.onDestroy();
Intent intent = new Intent(getApplicationContext(), MyAccessibilityService.class);
intent.putExtra("data","yourData");
startService(intent);
}
2)覆盖MyAccessibilityService的onStartCommand()方法:
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
String data="";
if(intent.getExtras().containsKey("data"))
data = intent.getStringExtra("data");
return START_STICKY;
}

1)在任何事件中从您的辅助功能服务中调用startActivity(intent)。
String msg = "your message";
Intent intent = new Intent(serviceContext, activityClassName.class);
intent.putExtra("message",msg);
startActivity(intent);
2)现在,在您的活动onCreate(Bundle bundle)方法中,您可以获得意图。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
String msg = intent.getStringExtra("message");
Log.e(LOG_TAG,"Message From Service - "+msg); //Message From Service - your message
}
使用Intent,您可以将数据从Service传递到Activity。
