所以我有一个原来的活动具有基本相同的确切code代表说，但我不得不把那个code到另一个活动。唯一的区别我可以告诉大家的是，文本到语音不叫在异步方法。口语发生在speakFull方法。 我得到这些错误：

 在线失败：不绑定到TTS引擎
isSpeaking失败：不绑定到TTS引擎
 

我是新来的android的发展，我通过其他办法解决这一问题已经搜查了，我真的不能似乎找到一个解决方案，使我的工作。任何意见或帮助是AP preciated。

解决方案

您只能叫的OnInit后发言（）（）被调用。因此，移动你的TTS中的onCreate说话code到的OnInit（）

  @覆盖
公共无效的OnInit（INT状态）{
    如果（状态== TextToSpeech.SUCCESS）{
         leftToRead = speakFull（RES）;

}
 

和初始化暂停为true 布尔暂停= TRUE;

So I had an original activity with basically the same exact code for speaking, but I had to move that code into another activity. The only difference I can tell is that the text to speech is not called in an asynchronous method. The speaking occurs in the speakFull method. I get these errors:

speak failed: not bound to TTS engine
isSpeaking failed: not bound to TTS engine

I'm new to android development, I've searched through other solutions to this problem, and I can't really seem to find a solution to make mine work. Any advice, or help is appreciated.

Code:

   package com.example.webview;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.speech.tts.TextToSpeech;
import android.text.method.ScrollingMovementMethod;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class ReadOut extends Activity implements TextToSpeech.OnInitListener, OnClickListener {


    boolean paused = false;
    String leftToRead = null;
    String res = null;

    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.read_out);
        Intent intent = getIntent();
        res = intent.getExtras().getString("response");
        TextView textv = (TextView) findViewById(R.id.textView1);
        textv.setText(res);
        textv.setMovementMethod(new ScrollingMovementMethod());
        android.view.Display display = ((android.view.WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); 
        textv.setHeight((int)(display.getHeight()*0.76));
        leftToRead = speakFull(res);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        return true;
    }

    public String speakFull(String text){
        System.out.println("Speaking: " + text);
        TextToSpeech tts = new TextToSpeech(this, this);
        System.out.println("Speaking");
        String[] sentences = text.split("\n|\\.(?!\\d)|(?<!\\d)\\."); // Regex that splits the body of text into the sentences of that body which are stored in a String array.
        for(int i = 0; i < sentences.length; i++){
            if(!tts.isSpeaking() && !paused){
                System.out.println("Speaking: " + i);
                tts.speak(sentences[i], TextToSpeech.QUEUE_FLUSH, null);
            }else if(paused){
                System.out.println("Paused");
                String paused = "";
                for(int j = i - 1; j < sentences.length; j++){
                    paused += sentences[j];
                }
                return paused;
            }else{
                i--;
            }
            if(i == sentences.length - 1){
                return "Message 001: Complete";
            }
        }
        return null;
    }

    @Override
    public void onInit(int arg0) {
        // TODO Auto-generated method stub

    }

    public void clickPause(View v){
        if(paused){
            paused = false;
            Button b = (Button) findViewById(R.id.button1);
            b.setText("Play");
        }else{
            paused = true;
            Button b = (Button) findViewById(R.id.button1);
            b.setText("Pause");
            if(leftToRead == null){
                leftToRead = speakFull(res);
            }else{
                leftToRead = speakFull(leftToRead);
            }
        }
    }

    @Override
    public void onClick(DialogInterface arg0, int arg1) {
        // TODO Auto-generated method stub

    }

}

You can only call speak() after onInit() was called. So move your tts speak code in onCreate to onInit()

@Override
public void onInit(int status) {
    if (status == TextToSpeech.SUCCESS) {
         leftToRead = speakFull(res);

}

and initialize pause to true boolean paused = true;
