发送消息到活动服务 - 机器人 [英] Send message from Activity to Service - Android

问题描述

我写的，而不是保持它在为Android键盘替代的应用程序，我需要，我需要在活动运行它的键盘定制化不够， InputMethodService 类。下面是我如何调用键盘我 InputMethodService 类：

I am writing a keyboard replacement app for Android, and I needed the keyboard customized enough that I need to run it in an Activity, instead of keeping it in the InputMethodService class. Here is how I call the keyboard from my InputMethodService class:

    @Override public void onStartInputView(EditorInfo attribute, boolean restarting) {
    super.onStartInputView(attribute, restarting);

    Intent intent = new Intent(this, Keyboard.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    context.startActivity(intent);

}

我现在已经碰到，我不能更新文本字段，其中从键盘输入应该去的问题。我试图创建一个静态InputConnection，在我的服务类，然后从活动更新它，但没有任何反应。

I have now run into the problem that I can't update the text field where the input from the keyboard should go. I tried creating a static InputConnection, in my service class, then updating it from the Activity, but nothing happens.

所以我想这里是我的问题：我能找到大量的信息如何从服务将数据发送到一个活动，但没有有关从活动将数据发送到服务（特别是输入法服务）。有谁知道如何做到这一点？

So I guess here is my question: I was able to find lots of info about how to send data from a Service to an Activity, but nothing about sending data from an Activity to a Service(specifically an input method service). Does anyone know how to do this?
