问题描述
我写这充分说明用户的活动，我很想阻塞TextToSpeech的初始化 - 否则超时。我怎样才能让我的线程等待？
I am writing an activity that speaks to the user and I'd really like to block on TextToSpeech initialization - or else time out. How can I get my thread to wait?
我想：
while (! mIsTtsReady || i>limit) try { Thread.sleep(100); i++; ... };
以及
@Override
public void OnInit() { mIsTtsReady = true; } // TextToSpeech.OnInitListener
不过的OnInit（）永远不会运行。似乎的OnInit（通过一个消息到我的活动活套？），这是在紧张的睡眠（）循环我的线程中执行。
But OnInit() never runs. It seems that OnInit executes within my thread (via a message to my activities Looper?), which is in a tight sleep() loop.
这似乎是错误的把我的大部分code（以下简称初始化之后的东西）到是OnInit本身。其移入一个Runnable，然后开始（）荷兰国际集团它，如上面睡了可运行的工作范围内。但现在我的code是在一个新的线程，需要明确的同步与UI等，而这一切就会变得混乱真的很快。
It seems wrong to put the bulk of my code (the "after init" stuff) into OnInit itself.Moving it into a Runnable, then start()ing it, and sleeping as above within that runnable works. But now my code is in a new thread and needs explicit syncing with the UI etc, and it all gets messy really quickly.
什么是正确的方式 - 或者至少是一个工程:) - 做到这一点
What is the right way - or at least one that works :) - to do this?
谢谢！
推荐答案
您需要初始化内如TTS系统该活动的onCreate（）方法，这样就可以使用它以后的用户，例如，当点击一个按钮。
You need to initialize the TTS system within e.g. the activities onCreate() method, so that you can use it later when the user e.g. clicks a button.
请参阅例如https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/OneTweetActivity.java#L62其中，setupspeak（）被调用，然后再说话（）（https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/OneTweetActivity.java#L344 ）其中，当用户点击发言按钮，然后调用
See e.g. https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/OneTweetActivity.java#L62 where setupspeak() is called and then later speak() ( https://github.com/pilhuhn/ZwitscherA/blob/master/src/de/bsd/zwitscher/OneTweetActivity.java#L344 ) which is then called when the user clicks the 'speak' button.
