Android 语音识别

1，判断是否支持语音识别

p_w_picpathbtn = (ImageButton)findViewById(R.id.p_w_picpathBtn01);
       p_w_picpathbtn.setOnClickListener(new View.OnClickListener() {
                            
           @Override
           public void onClick(View v) {
               // TODO Auto-generated method stub
     try{
 Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
 intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);  //设置为当前手机的语言类型
  intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "请说话，我识别");//出现语言识别界面上面需要显示的提示
   startActivityForResult(intent,REQUEST_CODE);
         }
catch(ActivityNotFoundException e){
   e.printStackTrace();
    Toast.makeText(MianActivity.this , "找不到语音设备",     Toast.LENGTH_SHORT).show();
                                  }
                                       }
       });

2，启动语音识别

ArrayList<String> results= data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
           //listView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list)); //把数据显示在listview中
           String resultsString = "";
           resultsString =resultsString+results.get(0);

3，获取识别结果，并以Toast显示出来

Toast.makeText(MianActivity.this, resultsString, Toast.LENGTH_SHORT).show();
           super.onActivityResult(requestCode, resultCode,data);
