我正在尝试使用react native对文本识别进行一些演讲.我编写了一个react模块来启动识别器意图

public class SpeechToTextModule extends ReactContextBaseJavaModule {...  @ReactMethod  public voID startListening(Callback errorCallback, Callback successCallback) {    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);    if(getCurrentActivity() != null){        getReactApplicationContext().startActivityForResult(intent, SPEECH_REQUEST_CODE, null);    } else {        errorCallback.invoke(new NullPointerException("Activity is null"));    }}  public voID onActivityResult(int requestCode, int resultCode, Intent data){    // control must come here  }

mainactivity看起来像这样：

public class MainActivity extends ReactActivity {  ...  @OverrIDe  public voID onActivityResult(int requestCode, int resultCode, Intent data) {    // how do i invoke the module function?  }}

MainActivity从语音意图接收结果,但是我无法弄清楚如何将其传递给模块.

解决方法:

有一种方法可以达到register as Activity event listener.

将此添加到您的本机模块：

public class SpeechToTextModule   extends ReactContextBaseJavaModule   implements ActivityEventListener {  public SpeechToTextModule(ReactApplicationContext reactContext) {    super(reactContext);    reactContext.addActivityEventListener(this); //Register this native module as Activity result Listener   }  @OverrIDe  public voID onActivityResult(Activity activity, int requestCode, int resultCode, Intent data) {    // Here is your Activity result :)  }  @OverrIDe  public voID onNewIntent(Intent intent) {  }}
