android - 如何以编程方式关闭 Android Speech To Text 对话框

Question

我是android编程的新手。
目前，我正在研究 android 中的 Speech To Text。
如果用户这样做，我想以编程方式关闭语音输入提示
什么都不说。

我该怎么做？

这是代码。

public void startSpeech(View view) {
    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,
            "Speak something");
    try {
        startActivityForResult(intent, 84);
    } catch (ActivityNotFoundException a) {
        Toast.makeText(getApplicationContext(),
                "Speech is currently not supported",
                Toast.LENGTH_LONG).show();
    }
}

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

    switch (requestCode) {
        case 84: {
            if (resultCode == RESULT_OK && data != null) {

                ArrayList<String> result = data
                      .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                // The spoken words...
            }
            // if user did not speak anything, then close the dialog.
            // ???
            break;
        }

    }
}

只需使用

finishActivity(REQ_CODE_SPEECH_INPUT);
