语音输入以填充android中的编辑文本? [英] Voice Input to Populate Edit Text in android?

问题描述

我正在研究android中的语音输入.我使用了

I am working on voice input in android. I used the sample from

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

在Xperia X10上进行测试时，我得到了立即讲话"对话框，但是在输入一些声音之前，它已经关闭.我正在尝试实施语音搜索，例如如果语音输入为James Bond，那么我想以"Edit Text"(姓氏)和"Last name Edit Text"(姓氏)填充James.它将在数据库中搜索名称.但是，在尝试使用API​​ Demo示例时，它无法正常工作.可能是我缺少了一些东西.是否有人会发布任何样本进行语音输入，而不是ApiDemos样本.

And while testing on Xperia X10, I got the "Speak now" dialog but before I input some voice it gets closed. I am trying to implement voice search e.g. If voice input is James Bond then I want to populate the James in first name Edit Text and Bond in Last name Edit Text. Which will search in database for the name. But while trying to use the API Demo sample, its not working. May be I am missing something. Will anybody post any sample for voice input rather than ApiDemos sample.

先谢谢了.

您可以使用以下代码进行语音识别.有关语音识别的完整教程，请

You can use the following code for voice recognition. For a complete tutorial for voice recognition, Click Here.

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.speech.RecognizerIntent;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;

/**
* A very simple application to handle Voice Recognition intents
* and display the results
*/
public class VoiceRecognitionDemo extends Activity
{

private static final int REQUEST_CODE = 1234;
private ListView wordsList;

/**
 * Called with the activity is first created.
 */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.voice_recog);

    Button speakButton = (Button) findViewById(R.id.speakButton);

    wordsList = (ListView) findViewById(R.id.list);

    // Disable button if no recognition service is present
    PackageManager pm = getPackageManager();
    List<ResolveInfo> activities = pm.queryIntentActivities(
            new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
    if (activities.size() == 0)
    {
        speakButton.setEnabled(false);
        speakButton.setText("Recognizer not present");
    }
}

/**
 * Handle the action of the button being clicked
 */
public void speakButtonClicked(View v)
{
    startVoiceRecognitionActivity();
}

/**
 * Fire an intent to start the voice recognition activity.
 */
private void startVoiceRecognitionActivity()
{
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Voice recognition Demo...");
    startActivityForResult(intent, REQUEST_CODE);
}

/**
 * Handle the results from the voice recognition activity.
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK)
    {
        // Populate the wordsList with the String values the recognition engine thought it heard
        ArrayList<String> matches = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);
        wordsList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
                matches));
    }
    super.onActivityResult(requestCode, resultCode, data);
}
}
