Android利用RecognizerIntent识别语音并简单实现打电话动作

关于Android利用RecognizerIntent识别语音并简单实现打电话，具体看实现代码如下：

package com.example.recognizerintentactivity;import java.util.ArrayList;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.speech.RecognizerIntent;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {private Button btnReconizer;private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btnReconizer = (Button) this.findViewById(R.id.btnRecognizer);btnReconizer.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubtry {// 通过Intent传递语音识别的模式，开启语音Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);// 语言模式和自由模式的语音识别intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);// 提示语音开始intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "开始语音");// 开始语音识别startActivityForResult(intent,VOICE_RECOGNITION_REQUEST_CODE);} catch (Exception e) {// TODO: handle exceptione.printStackTrace();Toast.makeText(getApplicationContext(), "找不到语音设备", 1).show();}}});}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {// TODO Auto-generated method stub// 回调获取从谷歌得到的数据if (requestCode == VOICE_RECOGNITION_REQUEST_CODE&& resultCode == RESULT_OK) {// 取得语音的字符ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);String resultString = "";for (int i = 0; i < results.size(); i++) {resultString += results.get(i);}if(resultString.indexOf("喂") >-1){String tel = "15100000000";Intent intent = new Intent();intent.setAction(Intent.ACTION_CALL);intent.setData(Uri.parse("tel:" + tel));startActivity(intent);Toast.makeText(this,tel, 1).show();}else{Toast.makeText(this, "没找到要拨打的电话", 1).show();}}super.onActivityResult(requestCode, resultCode, data);}}

这里，我们需要注意的是，需要用到两个权限，一个是网络资源，一个是打电话的这个动作权限，因此，我们需要修改 AndroidMainfest.xml增加两条内容，如下

<uses-permission android:name="android.permission.CALL_PHONE" /><uses-permission android:name="android.permission.INTERNET" />
