Android中用TTS语音朗读一段英文

     Android中自带的TTS语音服务，现在不能读取汉字，下面是我用来读取一段英文的代码，希望对大家有帮助：

package com.yu;import java.util.Locale;import android.app.Activity;import android.os.Bundle;import android.speech.tts.TextToSpeech;import android.speech.tts.TextToSpeech.OnInitListener;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.EditText;public class TTSTestActivity extends Activity {Button  button;EditText  edittext;TextToSpeech mSpeech;    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        edittext=(EditText)findViewById(R.id.edittext);        button=(Button)findViewById(R.id.button);        button.setEnabled(false);        mSpeech = new TextToSpeech(this, new OnInitListener()         {            @Override            public void onInit(int status)            {                if (status == TextToSpeech.SUCCESS)                {                    int result = mSpeech.setLanguage(Locale.ENGLISH);//设置只能朗读英文                    if (result == TextToSpeech.LANG_MISSING_DATA|| result == TextToSpeech.LANG_NOT_SUPPORTED)                    {//要是结果没值，就在后台打印出来                        Log.e("lanageTag", "not use");                    }                     else                     {//模拟机在启动时朗读下面的英文                        button.setEnabled(true);                        mSpeech.speak("Hello World,Hello Android", TextToSpeech.QUEUE_FLUSH, null);                    }                }            }        });        button.setOnClickListener(new Button.OnClickListener()         {            @Override            public void onClick(View v)             {//读取文本框里输入的英文                mSpeech.speak(edittext.getText().toString(),TextToSpeech.QUEUE_FLUSH, null);            }        });    }@Overrideprotected void onDestroy() {super.onDestroy();if (mSpeech != null) {            mSpeech.stop();            mSpeech.shutdown();        }}}
