安卓：runOnUiThread并不总是选择正确的线程？ [英] Android: runOnUiThread does not always choose the right thread?

问题描述

我有，保持阅读的话，用户的活动，并使用具有文字转语音onUtteranceCompleted完成code时显示的东西。

里面onUtteranceCompleted我有这个code延迟功能与第二：

  Runnable任务=新的Runnable（）{
    公共无效的run（）{
        // UI上运行
        runOnUiThread（新的Runnable（）{
            公共无效的run（）{
                readWord（）;
            }
        }）;
    }
};
worker.schedule（任务，1，TimeUnit.SECONDS）;
 

这看起来效果很好，但我认为这是造成问题。
当我转动我的手机屏幕（我猜这将启动一个新的活动）。
我听说在后台看了一些话。我想这是因为 runOnUiThread（）这使得该活动在后台继续。

我怎么能避免运行2活动？我想preFER如果我没有从做一些怪异的补丁停止旋转屏幕！

感谢您

编辑：

 公共无效readWord（）{
    如果（this.readingOnPause）{
        返回;
    }    txtCurrentWord.setText（CURRENTITEM [1]）;    this.hashAudio.put（TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID，字）;
    this.tts.setLanguage（Locale.US）;
    this.tts.speak（this.currentItem [1]，TextToSpeech.QUEUE_FLUSH，this.hashAudio）;
}
 

EDIT2：

工人的实例：

 私有静态最终ScheduledExecutorService的工人= Executors.newSingleThreadScheduledExecutor（）;
 

解决方案

好了，所以这是一个修复我想出了，如果有人有更好的解决办法，我在听。

1. 我添加的android：configChanges =keyboardHidden |方向在androidmanifest
的内部活动
2。

再当屏幕旋转是被调用函数：

  @覆盖
公共无效onConfigurationChanged（配置NEWCONFIG）
{
  super.onConfigurationChanged（NEWCONFIG）;
  的setContentView（R.layout.streaming）;  initializeUI（）; //包含所有findViewByID等...
}
 

I've got an activity that keeps reading words to the user, and using onUtteranceCompleted with textTospeech to display something when the code is completed.

Inside onUtteranceCompleted I have this code to delay a function with a second:

Runnable task = new Runnable() {
    public void run() {
        //runs on ui
        runOnUiThread(new Runnable() {
            public void run() {
                readWord();
            }
        });
    }
};
worker.schedule(task, 1, TimeUnit.SECONDS);

This seems like it works well, but I think it is causing a problem. When I rotate the screen of my phone (I guess this starts a new activity). I hear some words being read in the background. I guess this is because of runOnUiThread() which makes the activity continue in the background.

How could I avoid 2 activities running ? I would prefer if I don't have to stop the screen from rotating on doing some weird patch!

Thank you

EDIT:

public void readWord() {
    if (this.readingOnPause) {
        return;
    }

    txtCurrentWord.setText(currentItem[1]);

    this.hashAudio.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"word");
    this.tts.setLanguage(Locale.US);
    this.tts.speak(this.currentItem[1], TextToSpeech.QUEUE_FLUSH,this.hashAudio);
}

EDIT2:

instantiation of worker:

private static final ScheduledExecutorService worker = Executors.newSingleThreadScheduledExecutor();

解决方案

Ok so this is a fix I've come up with, if someone has a better solution, I'm listening.

1. I've added android:configChanges="keyboardHidden|orientation" inside the activity in the androidmanifest
2.

and then a function that is called when the screen is rotate:

@Override
public void onConfigurationChanged(Configuration newConfig)
{
  super.onConfigurationChanged(newConfig);
  setContentView(R.layout.streaming);

  initializeUI(); //contains all the findViewByID etc...
}
