java - 如何让ActivityResult输出到2个不同的textview？

Question

我想将语音转换为文本应用程序，但在不同的 TextView 上输出。我尝试在互联网上搜索解决方案，但大多数答案仅输出到 1 个 TextView 。我想让它看起来像这样:

这是我的想法的形象:/image/orTec.png

这是为了学习目的。我希望有人能帮助我

    TextView textview1, textview2;
    Button btnVoice1, btnVoice2;

    textview1= findViewById(R.id.textview1);
    textview2= findViewById(R.id.textview2);

    btnVoice1 = findViewById(R.id.btnVoice1);
    btnVoice2 = findViewById(R.id.btnVoice2);

    btnVoice1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startVoiceInput();
        }
    });

    btnVoice2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startVoiceInput();
        }
    });

//函数

    private void startVoiceInput(){
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
    RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say Something!");
    try {
        startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    } catch (ActivityNotFoundException a) {
        Toast.makeText(getApplicationContext(),
                getString(R.string.speech_not_supported),
                Toast.LENGTH_SHORT).show();
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
        case REQ_CODE_SPEECH_INPUT: {
            if (resultCode == RESULT_OK && null != data) {
                ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                textview1.setText(result.get(0));
                // how to make textview2 output when btnVoice2 is click
            }
            break;
        }

    }
}

对于单个 Activity 的多个 onActivityResult，请像这样更改代码:

    int REQ_CODE_SPEECH_INPUT=100;
    int REQ_CODE_SPEECH_INPUT_SECOND=101;
    TextView textview1, textview2;

        Button btnVoice1, btnVoice2;

        textview1= findViewById(R.id.textview1);
        textview2= findViewById(R.id.textview2);

        btnVoice1 = findViewById(R.id.btnVoice1);
        btnVoice2 = findViewById(R.id.btnVoice2);

        btnVoice1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startVoiceInput(REQ_CODE_SPEECH_INPUT);
            }
        });

        btnVoice2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startVoiceInput(REQ_CODE_SPEECH_INPUT_SECOND);
            }
        });


    private void startVoiceInput(int code){
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
        RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say Something!");
        try {
            startActivityForResult(intent, code);
        } catch (ActivityNotFoundException a) {
            Toast.makeText(getApplicationContext(),
                    getString(R.string.speech_not_supported),
                    Toast.LENGTH_SHORT).show();
        }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {

            case REQ_CODE_SPEECH_INPUT: {
                if (resultCode == RESULT_OK && null != data) {
                    ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                    textview1.setText(result.get(0));

                }
                break;
            }
            case REQ_CODE_SPEECH_INPUT_SECOND:{
                    if (resultCode == RESULT_OK && null != data) {
                    ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                    textview2.setText(result.get(0));

                }
                break;
            }


        }
    }
