Question

我想通过Speech to text（STT）在Listview中搜索。我有一个城市列表，现在是STT的用户搜索。此搜索仅适用于我的列表视图（如STT联系人搜索），

Answer 1

Speech to Text内置于Android 1.6+中。这是一个如何做的简单示例。

 /**
 * Showing google speech input dialog
 * */
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));
    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);
            txtSpeechInput.setText(result.get(0));
        }
        break;
    }

    }
}

请尝试使用此代码进行过滤视图。

请参阅此代码Google Voice in our Application

/* Google Voice open while calling Activity */
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)          
{

    /* Call Activity to Open Google Voice */
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

    try {
        startActivityForResult(intent, 1);
    } catch (ActivityNotFoundException a) {
       Log.d("LOG",a.getMessage());
    }
}

/* This will be called after you speak */
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
    case 1: {
        if (resultCode == Activity.RESULT_OK && null != data) {

            ArrayList text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

           Log.d("LOG","You have speak  : "+text.get(0));
        }
        break;
    }
    }
}

您将获得text.get(0)，因为您可以在过滤ListView时使用拼写字符串。

notifyDataSetChanged()对于使用新数据更改ListView非常有用。
