如何在具有多个LinearLayout的textView上使用TextToSpeech？

我＆＃39;试图在电子邮件上添加TTS方法来阅读它，所以我从开源处工作邮件客户端并开始在其中添加TTS代码，所以当点击按钮时，应该大声读出消息

这就是我的所作所为：

活动类的名称是MessageContainerView

unsignedText = (TextView) findViewById(R.id.message_unsigned_text);

buttonRead =(Button)findViewById(R.id.button);



t1=new TextToSpeech(activity.getApplicationContext(), new TextToSpeech.OnInitListener() {
    @Override
    public void onInit(int status) {
        if(status != TextToSpeech.ERROR) {
            t1.setLanguage(Locale.UK);

        }
    }
});

buttonRead.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String toSpeak = unsignedText.getText().toString();
        Toast.makeText(activity.getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show();
        t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
    }
});

但是当我点击按钮时，应用停止了

这是因为多个LinearLayout？所以TTS代码无法访问TextView中的文本？

Answer 1

文本到语音逐个多个文本。这个

 private void speakOut () {
        String que = tvone.getText().toString();
        String op1 = tvtwo.getText().toString();
        String op2 = tvthree.getText().toString();
        String op3 = tvfoure.getText().toString();
        String op4 = tvfive.getText().toString();
        tts.speak(que, TextToSpeech.QUEUE_ADD, null);
        tts.speak(op1, TextToSpeech.QUEUE_ADD, null);
        tts.speak(op2, TextToSpeech.QUEUE_ADD, null);
        tts.speak(op3, TextToSpeech.QUEUE_ADD, null);
        tts.speak(op4, TextToSpeech.QUEUE_ADD, null);

    }

TextView上的TextToSpeech有多个LinearLayout？
