## 实现步骤： ##

1.  创建TextToSpeech对象，创建时传入OnInitListener监听器
2.  设置TextToSpeech所使用的语言、国家选项
3.  调用speak()或synthesizeToFile方法
4.  关闭TTS，回收资源

--------------------

*  在布局中加入EditText用于获取文字，加入Button用于控制播放或存储合成的声音文件
 *  代码：  
    
    
     *  初始化

TextToSpeech textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
                @Override
                public void onInit(int status) {
                    if (status == TextToSpeech.SUCCESS) {
                        int result = textToSpeech.setLanguage(Locale.US);
                        if (result != TextToSpeech.LANG_COUNTRY_AVAILABLE && result != TextToSpeech.LANG_AVAILABLE) {
                            Toast.makeText(MainActivity.this, "暂不支持该语言", Toast.LENGTH_SHORT).show();
                        }
                    }
                }
            });

*  播放或存储为文件

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
            fab.setOnClickListener(new View.OnClickListener() {
                @TargetApi(Build.VERSION_CODES.LOLLIPOP)
                @Override
                public void onClick(View view) {
                    textToSpeech.setSpeechRate(1);
                    textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_ADD, null, "speech");
                    Snackbar.make(view, "是否存储该声音文件", Snackbar.LENGTH_LONG)
                            .setAction("存储", new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    textToSpeech.synthesizeToFile(editText.getText().toString(), null, new File("/mnt/sdcard/sound.mp3"), "record");
                                    Toast.makeText(MainActivity.this, "存储成功", Toast.LENGTH_SHORT).show();
                                }
                            }).show();
                }
            });

*  回收资源

protected void onDestroy() {
            super.onDestroy();
            if (textToSpeech != null) {
                textToSpeech.shutdown();
            }
        }
