我正在測試VoiceRecognition.i已搜索並未找到任何可行的答案。 這裏是代碼。綁定到識別服務失敗
import android.content.Intent;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import java.util.List;
public class MainActivity extends AppCompatActivity implements View.OnClickListener, RecognitionListener {
Button button;
SpeechRecognizer speechRecognizer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
speechRecognizer.setRecognitionListener(this);
button.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
private static final int SPEECH_REQUEST_CODE = 0;
// Create an intent that can start the Speech Recognizer activity
private void displaySpeechRecognizer() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
this.getPackageName());
speechRecognizer.startListening(intent);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {
List<String> results = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
System.out.println(spokenText);
// Do something with spokenText
}
super.onActivityResult(requestCode, resultCode, data);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button:
displaySpeechRecognizer();
break;
}
}
@Override
public void onReadyForSpeech(Bundle params) {
System.out.println("onReadyForSpeech");
}
@Override
public void onBeginningOfSpeech() {
System.out.println("onBeginningOfSpeech");
}
@Override
public void onRmsChanged(float rmsdB) {
System.out.println("onRmsChanged");
}
@Override
public void onBufferReceived(byte[] buffer) {
System.out.println("onBufferReceived");
}
@Override
public void onEndOfSpeech() {
System.out.println("onEndOfSpeech");
}
@Override
public void onError(int error) {
System.out.println("onError");
}
@Override
public void onResults(Bundle results) {
System.out.println("onResults");
}
@Override
public void onPartialResults(Bundle partialResults) {
System.out.println("onPartialResults");
}
@Override
public void onEvent(int eventType, Bundle params) {
System.out.println("onEvent");
}
}
，這是佈局。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

android:text="whats up"
android:id="@+id/button"
android:layout_below="@+id/textView"
android:layout_centerHorizontal="true"
android:layout_marginTop="94dp" />
</RelativeLayout>
這裏是清單

</application>
</manifest>
我收到此錯誤 - > 「voicerecognition E/SpeechRecognizer：結合識別服務失敗」 也找不到它的任何工作示例。
