Android TextToSpeech简单使用
如何让Android手机读取文本呢？Android SDK为开发者提供了TTS技术，开发者只需要做简单的调用就可以完成让Android读取文本的功能。示例的功能是点击按钮后，朗读TextVeiw中的文本，UI如下：

对TextToSpeech的实例添加OnInitListener()和OnUtteranceCompletedListener()来实现对TTS状态的监听，并在需要时，添加自己的逻辑代码。这个功能的核心代码如下：
package com.anhuioss.tts;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.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class TTSActivity extends Activity implements OnClickListener, OnInitListener {Button speechButton;TextView speechText;TextToSpeech textToSpeech; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); speechButton = (Button) findViewById(R.id.button1); speechText = (TextView) findViewById(R.id.textView1); speechButton.setOnClickListener(this); textToSpeech = new TextToSpeech(this, this); }@Overridepublic void onClick(View v) {if (textToSpeech != null && !textToSpeech.isSpeaking()) {textToSpeech.speak(speechText.getText().toString(), TextToSpeech.QUEUE_FLUSH, null);}}@Overridepublic void onInit(int status) {if (status == TextToSpeech.SUCCESS) {int result = textToSpeech.setLanguage(Locale.US);if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {Toast.makeText(this, "Denotes the language data is missing or the language is not supported.", Toast.LENGTH_SHORT).show();}}}@Overrideprotected void onStop() {super.onStop();textToSpeech.stop();textToSpeech.shutdown();}} 希望对你有所帮助，如需代码，请点击此处！=^_^=
