问题描述
我用这个例子从newboston,它提示我的记录之后却承认我所说的话,也不会更新列表视图。
I'm using this example from newboston and it prompt me for recording but after it recognized what I said, it won't update the list view.
下面是code。
public class MainActivity extends Activity {
private static final int RECOGNIZER_RESULT = 1234;
ListView list;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.list);
Button btn_speach = (Button)findViewById(R.id.btn_speak);
btn_speach.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
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 to search");
startActivityForResult(intent, RECOGNIZER_RESULT);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == RECOGNIZER_RESULT && requestCode == RESULT_OK){
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
list.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, matches));
for(int i = 0; i < matches.size(); i++){
Log.i("MainActivity", matches.get(i));
}
}
super.onActivityResult(requestCode, resultCode, data);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
下面是XML的布局。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/btn_speak"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Button" />
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/button1" >
</ListView>
</RelativeLayout>
我没有得到任何错误。而下面的code不会是打印在LogCat中任何东西。
I do not get any errors. And the following code does not print anything in LogCat either.
for(int i = 0; i < matches.size(); i++){
Log.i("MainActivity", matches.get(i));
}
和我测试我有语音识别功能的Android设备上。
And I'm testing on my android device which has Speech Recognition functionality.
推荐答案
你可以试试这个code ..它在我的应用程序运行...
you can try this code .. it is running in my app...
import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
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;
public class MainActivity extends Activity {
Button speak;
ListView options;
ArrayList<String> results;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//doctory endsl...
speak = (Button) findViewById(R.id.bSpeak);
options = (ListView) findViewById(R.id.lvOptions);
speak.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// This are the intents needed to start the Voice recognizer
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
// RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 15); // number of maximum results..
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say something");
startActivityForResult(i, 1010);
}
});
// retrieves data from the previous state. This is incase the phones
// orientation changes
if (savedInstanceState != null) {
results = savedInstanceState.getStringArrayList("results");
if (results != null) {
options.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, results));
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
// retrieves data from the VoiceRecognizer
if (requestCode == 1010 && resultCode == RESULT_OK) {
results = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (results.contains("close"))
{
finish();
}//extra testing...
options.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, (results));
}
super.onActivityResult(requestCode, resultCode, data);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
// This should save all the data so that when the phone changes
// orientation the data is saved
super.onSaveInstanceState(outState);
outState.putStringArrayList("results", results);
}
}
和XML是...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ListView
android:id="@+id/lvOptions"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/button1" >
</ListView>
<Button
android:id="@+id/bSpeak"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Speak" />
