在Cordova中传递onActivityResult [英] Passing onActivityResult in Cordova
本文介绍了在Cordova中传递onActivityResult的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Cordova有任何自动方式传递onActivityResult到其CordovaPlugin类吗？
Does Cordova have any automatic way to pass onActivityResult to its CordovaPlugin classes?
这是我当前的文件，手动执行：
Here's my current file, doing it manually:
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());
}
}
使用 https：// github中使用的相同技术.com / apache / cordova-plugin-camera / blob / master / src / android / CameraLauncher.java 来获取通过自动传递的数据 - 但它崩溃。这里是一个工作（手动和没有数据传递）和非工作（自动数据传递）版本的目标类。
I tried to use the same technique employed in https://github.com/apache/cordova-plugin-camera/blob/master/src/android/CameraLauncher.java to get the data passed through "automatically" -- but it crashes. Here is a working (manual and no data pass-through) and non-working (automatic data pass-through) version of the target class. First working, then non-working.
无工作，无数据传递：

推荐答案
原来，我需要做的是运行 cordova.setActivityResultCallback（this）; 之前 cordova.getActivity （）.startActivityForResult（intent，REQUEST_CODE_PICK_ACCOUNT）; 。
Turns out that all I needed to do was to run cordova.setActivityResultCallback (this); before cordova.getActivity().startActivityForResult (intent, REQUEST_CODE_PICK_ACCOUNT);.
