在 Cordova 中传递 onActivityResult

Question

Cordova 是否有任何自动方式将 onActivityResult 传递给其 CordovaPlugin 类？

这是我当前的文件，手动操作：

package com.myapp;

import android.os.Bundle;
import org.apache.cordova.*;

import android.content.Intent;

import com.flyingsoftgames.googleplaytoken.GooglePlayToken;

public class MyApp extends CordovaActivity {

 @Override protected void onActivityResult (int requestCode, int resultCode, Intent data) {
  GooglePlayToken.runOnActivityResult (requestCode, resultCode, data);
 }

 @Override public void onCreate (Bundle savedInstanceState) {
  super.onCreate (savedInstanceState);
  super.init ();
  super.loadUrl(Config.getStartUrl());
 }
}

我尝试使用https://github.com/apache/cordova-plugin-camera/blob/master/src/android/CameraLauncher.java 中使用的相同技术来“自动”传递数据——但它崩溃了。这是目标类的工作（手动和无数据传递）和非工作（自动数据传递）版本。首先工作，然后不工作。

工作，没有数据传递：

 @Override public void initialize (CordovaInterface initCordova, CordovaWebView webView) {
  cordova = initCordova;
  super.initialize (cordova, webView);
 }

 private void pickUserAccount () {
  String[] accountTypes = new String[]{"com.google"};
  Intent intent = AccountPicker.newChooseAccountIntent(null, null, accountTypes, false, null, null, null, null);
  cordova.getActivity().startActivityForResult (intent, REQUEST_CODE_PICK_ACCOUNT);
 }

 public static void runOnActivityResult (int requestCode, int resultCode, Intent data) {
  if ((requestCode == REQUEST_CODE_PICK_ACCOUNT) && (resultCode == Activity.RESULT_OK)) {
   new RetrieveTokenTask().execute (data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME));
  }
 }

 public boolean execute (String action, JSONArray inputs, CallbackContext callbackContext) throws JSONException {
 if ("tryConnect".equals(action)) {
   tryConnect (callbackContext);
  } else if ("getAccessToken".equals(action)) {
   callbackContext.sendPluginResult (new PluginResult (PluginResult.Status.OK, accessToken));
  }
  return true;
 }

 // tryConnect runs the callback with a value of false if Google Play Services isn't available.
 public void tryConnect (CallbackContext callbackContext) {
  tryConnectCallback = callbackContext;
  pickUserAccount ();
 }


 private static class RetrieveTokenTask extends AsyncTask<String, Void, String> {
  @Override protected String doInBackground (String... params) {
   String accountName = params[0];
   String scope = "oauth2:" + Scopes.PROFILE;
   Context context = cordova.getActivity().getApplicationContext();
   try {
    accessToken = GoogleAuthUtil.getToken(context, accountName, scope);
   } catch (IOException e) {
    String errormessage = e.getMessage();
    if (tryConnectCallback != null) tryConnectCallback.error ("Error: " + errormessage + "."); tryConnectCallback = null;
   } catch (UserRecoverableAuthException e) {
    cordova.getActivity().startActivityForResult (e.getIntent(), REQ_SIGN_IN_REQUIRED);
   } catch (GoogleAuthException e) {
    String errormessage = e.getMessage();
    if (tryConnectCallback != null) tryConnectCallback.error ("Error: " + errormessage + "."); tryConnectCallback = null;
   }
   return accessToken;
  }

  @Override protected void onPostExecute (String newAccessToken) {
   super.onPostExecute (newAccessToken);
   accessToken = newAccessToken;
   if (tryConnectCallback != null) {
    tryConnectCallback.sendPluginResult (new PluginResult (PluginResult.Status.OK, accessToken));
    tryConnectCallback = null;
   }
  }
 }
}

作者已经回答了这个问题，但如果有人想要一个更简单的例子，这对我有用...

public final int MY_OP = 11;
private CallbackContext callback = null;

@Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException 
{
    if (action.equals("SERVICE NAME")) 
    {
        String param = "";
        try
        {
            param = args.getString(0);
        }
        catch( Exception e )
        {
        }

        callback = callbackContext;

        cordova.setActivityResultCallback (this);

        Intent intent = new Intent();
        intent.setClassName("com.pkg.drs","com.pkg.drs.ActivityToCall");
        intent.putExtra("my_param", param);

        cordova.startActivityForResult (this, intent, MY_OP);
        return true;
    }

    return false;
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    if( requestCode == MY_OP )
    {
        if( resultCode == Activity.RESULT_OK && data.hasExtra("return_val") )
        {
            PluginResult result = new PluginResult(PluginResult.Status.OK, data.getStringExtra("return_val"));
            result.setKeepCallback(true);
            callback.sendPluginResult(result);
        }
        else
        {
            PluginResult result = new PluginResult(PluginResult.Status.ERROR, "no params returned successfully" );
            result.setKeepCallback(true);
            callback.sendPluginResult(result);
        }
    }
}

结果我需要做的就是在cordova.getActivity().startActivityForResult (intent, REQUEST_CODE_PICK_ACCOUNT); 之前运行cordova.setActivityResultCallback (this);。
