如何在android中将语音转换为文本时获取过去的信息？

当我正在开发一个android应用程序并希望将语音转换为文本时，我正在使用内置的Google语音输入活动将语音转换为文本。我需要过去的信息，但它不断得到清除，我只有当前的回应。如何处理与谷歌语音键盘相同的问题。正如我所说，它包含了对当前字符串脚背的清除

MainActivity.java

public class MainActivity extends AppCompatActivity
  {
     private EditText txtSpeechInput;
     private ImageButton btnSpeak;
     private final int REQ_CODE_SPEECH_INPUT = 100;

 @Override
  protected void onCreate(Bundle savedInstanceState)
   {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      txtSpeechInput =  findViewById(R.id.txtSpeechInput);
      btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
    btnSpeak.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            promptSpeechInput();
        }
    });
   private void promptSpeechInput()
      {
    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,
            getString(R.string.speech_prompt));
    intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 20000000);

  try
    {
        startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    }
    catch (ActivityNotFoundException a)
    {
        Toast.makeText(getApplicationContext(),
                getString(R.string.speech_not_supported),
                Toast.LENGTH_SHORT).show();
    }
}
    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)
            {

              final ArrayList<String> result= data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);


                txtSpeechInput.setText(result.get(0));
            }
            break;
        }

    }
}

如果您只想保存一个以前检测到的字符串，为此，您需要创建一个全局字符串变量，并将结果列表中的值存储在该变量中。（保存与您在文本视图中设置的相同字符串）。但是，如果要保存所有字符串，则需要将全局字符串数组列表设置为，并将所有这些字符串添加到该数组列表中。下面是相关代码

private EditText txtSpeechInput;
private ImageButton btnSpeak;
private final int REQ_CODE_SPEECH_INPUT = 100;
private List<String> previousStringList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    previousStringList = new ArrayList<>();

    txtSpeechInput = findViewById(R.id.txtSpeechInput);
    btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
    btnSpeak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            promptSpeechInput();
        }
    });
}

private void promptSpeechInput() {
    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,
            getString(R.string.speech_prompt));
    intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 20000000);

    try {
        startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    } catch (ActivityNotFoundException a) {
        Toast.makeText(getApplicationContext(),
                getString(R.string.speech_not_supported),
                Toast.LENGTH_SHORT).show();
    }
}

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) {

                final ArrayList<String> result = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);


                txtSpeechInput.setText(result.get(0));
                if (result.get(0) != null) {
                    previousStringList.add(result.get(0));
                }
            }
            break;
        }

    }
}

这些单词存储在ArrayList中

你可以在这里看到一个实现的例子，它运行良好。应用程序存储单词，然后还执行请求的操作

你所说的过去的信息是什么意思？我从你的问题中了解到，你也想得到以前设置的字符串吗？是的，确切地说@Abdulwaheedy你想只保存以前的字符串或连续保存所有字符串吗？想连续保存所有字符串。当他开始讲之前的字符串时，不应该清除HMMM好的，我正在更新我的答案。
