Question

我阅读了许多博客，但在调用shutdown后仍然面临更新文本字符串的问题。下次点击播放时，会说出旧字符串和新字符串。这是代码：

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.batful);
    try {


        editor = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()).edit();
        // editor.putBoolean("b", true).apply();
        sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
        value = sharedPreferences.getString("personalmessage", null);
        Log.e("Voice Message create: ", value);


        value = sharedPreferences.getString("personalmessage", null);

        textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int i) {
                if (i != TextToSpeech.ERROR) {

                    textToSpeech.setLanguage(Locale.ENGLISH);
                       /* textToSpeech.setLanguage(Locale.getDefault());*/

                    final Handler h = new Handler();

                    h.postDelayed(new Runnable() {
                        public void run() {

                            if (Build.VERSION.SDK_INT >= 21) {

                                textToSpeech.speak(value, TextToSpeech.QUEUE_FLUSH, null, null);

                            } else {
                                textToSpeech.speak(value, TextToSpeech.QUEUE_FLUSH, null);
                            }
                            h.postDelayed(this, delay);
                        }
                    }, delay);

                }
            }
        });


        stopvol = (TextView)

                findViewById(R.id.stop);
        stopvol.setOnClickListener(new View.OnClickListener()

        {
            @Override
            public void onClick(View view) {

                turnoffbeep(getApplicationContext());
                finish();
            }
        });
    } catch (
            Exception e)

    {
        e.printStackTrace();
    }

}

static void turnoffbeep(Context contextforstat) {

    Log.i(TAG, "Turn Off beep");

    if ((textToSpeech != null)) {
        //    textToSpeech.stop();
        textToSpeech.shutdown();


    }
}

如果您看到添加了QUEUE_FLUSH但未达到结果。看看Android文档，我相信我的注意力是正确的。仍然如果有人帮助我寻找不丢弃旧文本的正确理由，请

如果我将共享首选项的输入更改为编辑文本，那么就是其他事实，它说的是最新的文本而不是旧的。

Answer 1

在R＆amp; D遇到问题之后，处理器正在制造混乱并选择旧文本。由于关闭不取消处理程序，重放是向现有的添加另一个处理程序。

Queue_Flush不刷新文本并更新
