私は現在、JAVA でキャリアを積むことを検討しており、アプリの構築から始めることにしました。ここに、音声認識をトリガーするために使用しているこのコードがあります。
public class MainActivity extends Activity implements OnClickListener{
private static final int VR_REQUEST = 999;
private ListView wordList;
private final String LOG_TAG = "SpeechRepeatActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button speechBtn = (Button) findViewById(R.id.speech_btn);
wordList = (ListView) findViewById (R.id.word_list);
PackageManager packManager= getPackageManager();
List<ResolveInfo> intActivities = packManager.queryIntentActivities
(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (intActivities.size() !=0){
speechBtn.setOnClickListener(this);
} else {
speechBtn.setEnabled(false);
Toast.makeText(this,"Oops - Speech Recognition Not Supported!",
Toast.LENGTH_LONG).show();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void onClick(View v){
if (v.getId() == R.id.speech_btn) {
listenToSpeech();
}
}
private void listenToSpeech() {
//start the speech recognition intent passing required data
Intent listenIntent =
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//indicate package
listenIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
getClass().getPackage().getName());
//message to display while listening
listenIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say a word!");
//set speech model
listenIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
//specify number of results to retrieve
listenIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
//start listening
startActivityForResult(listenIntent, VR_REQUEST);
}
@Override
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
//check speech recognition result
if (requestCode == VR_REQUEST && resultCode == RESULT_OK) {
//store the returned word list as an ArrayList
ArrayList<String> suggestedWords = data.
getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
//set the retrieved list to display in the ListView
//using an ArrayAdapter
wordList.setAdapter(new ArrayAdapter<String>
(this, R.layout.word, suggestedWords));
}
//this detects which one the user clicks
wordList.setOnItemClickListener(new OnItemClickListener(){
//click listener for items within list
public void onItemClick(AdapterView<?> parent,
View view, int position, long id){
//cast the
TextView wordView = (TextView)
//retrive the chosen word
String wordChosen= (String) wordView.
//output for debugging
Log.v(LOG_TAG, "chosen:" +wordChosen);
}});
super.onActivityResult(requestCode, resultCode, data);
}
}
このアプリでは、ユーザーがボタンを押すと Google 音声入力画面が表示され、ボタンをクリックすると (実際には自動的に進みます)、話すことができ、停止して表示されます。ただし、そのウィンドウがまったくポップアップしないようにします。代わりに、ユーザーがボタンをクリックして話すことができるようにし、アプリを停止してテキストを自動的に表示できるようにします (既に実行されています)。
お願いします！これを行う方法を示すフォームに既に回答があることを理解しています。実際、ユーザー名 JEEZ がここにコードを投稿しました。
これをプロジェクトファイルのどこに置くべきか理解できたかどうかわかりません。私はNOOBです！誰かがこれを明確にするのを助けることができれば、私はあなたの助けに大いに感謝します.
これが私のコードです：
