java - 合并两个 "OnActivityResult"方法

Question

如果你们中有人见过我，就会知道我对 Java 非常基础。我的大部分知识都是从各种来源自学的:在本例中，代码主要是从在线教程中获取和修改的。我正在尝试创建这个非常简单的人工智能，它允许您 1)使用语音识别 2)回复。问题是，我的两个代码都使用 OnActivityResult 方法:而且我不知道如何组合它们并保持其工作。两者的代码都可以完美工作，但由于方法同名，它们不能同时工作。这是两个方法，以及第一个调用的方法。

知道如何让这两种方法同时工作吗？

Answer 1

方法 onActivityResult 中的 requestCode 在此充当关键。您必须为不同的 Activity 定义不同的 requestCode。

Activity 1

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
try {
    startActivityForResult(intent, 1);
} catch (ActivityNotFoundException a) {
    Toast t = Toast.makeText(getApplicationContext(), "Opps! Your device doesn't support Speech to Text",Toast.LENGTH_SHORT);
    t.show();
} 

Activity 2

Intent check = new Intent();
check.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(check, 2); 

onActivityResult

public void onActivityResult(int requestCode, int resultCode, Intent data){
  super.onActivityResult(requestCode, resultCode, data);
  switch (requestCode){
  case (1): 
       //Code for Speech Recognition  
    break;

  case (2):
       //Code for Speech Synthesis (Text to Speech)
    break;
}

请注意，我在这里使用了两个不同的数字 -

startActivityForResult(intent, 1);

startActivityForResult(check, 2);

这 1 和 2 是请求代码。然后 noActivityResult 方法会相应地切换。我已经定制了您的代码。只需替换 Intent 声明即可。然后通过为不同的 Activity 添加单独的代码来编辑 onActivityResult。
