我編碼的簡單語音識別應用程序無法按預期工作。基本上,日誌上沒有可見的錯誤,編譯也很好,但是當我點擊按鈕時,語音識別功能彈出並開始錄製,但錄製完成後,沒有任何應用程序屏幕上顯示listview應顯示的內容無論記錄(以文本格式)Android上的簡單語音識別應用程序無法按預期工作
這裏是Java代碼
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
public class Voice extends Activity implements View.OnClickListener {
ListView lv;
final static int check = 1111;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.voice);
lv = (ListView) findViewById(R.id.lvVoiceReturn);
Button b = (Button) findViewById(R.id.bVoice);
b.setOnClickListener(this);
}
@Override
public void onClick(View v) {
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); // set speech recognizer intent
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); //set language
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak up son!"); // set prompt to user
startActivityForResult(i, check);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == check && resultCode == RESULT_OK) {
// create an empty array list and link it to the recognizer intent
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
// link the listview from my layout to the arraylist I created just now with the results from voice recognition
lv.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, results));
}
}
}
這裏是XML佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/bVoice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Click to Speak" />
<ListView
android:id="@+id/lvVoiceReturn"
android:layout_width="match_parent"
android:layout_height="fill_parent" />
</LinearLayout>
謝謝!
愚蠢的錯誤。我沒有連接到互聯網。該應用程序現在可以工作,並且我認爲語音識別需要連接。但是,感謝Aditi! – Kalid
