解决方法

**编辑：不要忘记权限：Manifest.permission.RECORD_AUDIO

您可以创建语音意图来捕获语音，然后通过 onActivityResult

回想语音

创建意图

        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
           intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,Locale.getDefault());
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT,"Speak to search");
        try {
           startActivityForResult(intent,123456);
        } catch (ActivityNotFoundException a) {
           //show toast?
        }
     }

然后在 onActivityResult 中，捕获语音并将其传递给您的搜索。

@Override
   protected void onActivityResult(int requestCode,int resultCode,Intent data) {
      super.onActivityResult(requestCode,resultCode,data);
      switch (requestCode) {
         case 123456: {
            if (resultCode == RESULT_OK && data != null) {
               ArrayList result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
               textView.setText(result.get(0));
            }
            break;
         }
      }
   }
