java - Android 上的简单语音识别应用程序无法按预期工作

Question

我编写的一个简单的语音识别应用程序无法按我的预期工作。基本上，日志上没有明显的错误，并且编译得很好，但是当我单击按钮时，语音识别功能会弹出并开始录制，但录制完成后，应用程序屏幕上不会出现任何内容， ListView 应该显示录制的内容(以文本格式)

这是java代码

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));
        }

    }
}

这是 xml 布局

<?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>

谢谢!

@Kalid 你可以尝试将语言设置为intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");并使用调试或日志检查应用程序控件是否转到 onActivityResult
