无法实现谷歌API示例(VoiceRecognition) [英] Can't implement Google API Sample (VoiceRecognition)
问题描述
我很新的Android开发,我想创建一个基本的应用程序,它利用了VoiceRecognition设施,以显示所说的文字...
I am very new to Android development, I am trying to create a basic application that makes use of the VoiceRecognition facility to display the text spoken...
package com.example.android.apis.app;
import com.example.android.apis.R;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;
/**
* Sample code that invokes the speech recognition intent API.
*/
public class VoiceRecognition extends Activity implements OnClickListener {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;
private ListView mList;
/**
* Called with the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Inflate our UI from its XML layout description.
setContentView(R.layout.voice_recognition);
// Get display items for later interaction
Button speakButton = (Button) findViewById(R.id.btn_speak);
mList = (ListView) findViewById(R.id.list);
// Check to see if a recognition activity is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() != 0) {
speakButton.setOnClickListener(this);
} else {
speakButton.setEnabled(false);
speakButton.setText("Recognizer not present");
}
}
/**
* Handle the click on the start recognition button.
*/
public void onClick(View v) {
if (v.getId() == R.id.btn_speak) {
startVoiceRecognitionActivity();
}
}
/**
* Fire an intent to start the speech 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, "Speech recognition demo");
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
/**
* Handle the results from the recognition activity.
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
// Fill the list view with the strings the recognizer thought it could have heard
ArrayList<String> matches = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
matches));
}
super.onActivityResult(requestCode, resultCode, data);
}
}
我创建了一个类,谷歌提供的VoiceRecognition code:
I created a class with the VoiceRecognition code provided by Google:
它经历了千百年来编译,因为它不停地抱怨com.example.android.apis.R无法得到解决......我进口API中提供相关的XML文件,并把它变成主要的。 XML
It took ages to compile as it kept complaining about the "com.example.android.apis.R" that could not be resolved... I imported the relevant XML file provided in the API and placed it into the main.xml
<?xml version="1.0" encoding="utf-8"?>
<!--
...
-->
<!-- This activity displays UI for launching voice recognition -->
<LinearLayout xmlns:android="......."
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="4dip"
android:text="@string/voice_recognition_prompt" />
<Button android:id="@+id/btn_speak"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/speak_button" />
<ListView android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1" />
</LinearLayout>
和我添加了voice_recognition_prompt和speak_button字符串值文件(这是所有新的给我,我不知道我在正确的顺序做这些事)。
And I added the voice_recognition_prompt and the speak_button strings to the value file (this is all new to me, i am not sure I have done these things in the right order).
最后应用程序编译,但它只是给出了一个强制关机的错误消息。有没有办法,我可能已经错过任何特别的动作呢?一些具体的项目配置为使用谷歌API的样品?
Finally the app compiles but it just gives a force shut down error message. Is there any particular step that I may have missed? Some specific project configuration to use this Google API sample?
我真的AP preciate你的帮助。
I really appreciate your help.
推荐答案
您好亚历克斯·请使用下面的XML文件: -
Hello Alex Please Use Following XML File:-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingBottom="4dip"
android:text="prompt" />
<Button android:id="@+id/btn_speak" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="speak" />
<ListView android:id="@+id/list" android:layout_width="fill_parent"
android:layout_height="0dip" android:layout_weight="1" />
</LinearLayout>
再检查,你的部队密切错误就解决了。
then check, your force close error is solved.
