Android onActivityResult從未啓動

我很抱歉再次詢問相同內容，但在查找答案後，我沒有一個可正常工作的代碼。Android onActivityResult從未啓動

n這就是我所說的活性主要功能：

package com.phonegap.CameraPluginTest; 

import android.app.Activity; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.util.Log; 

import com.phonegap.DroidGap; 

public class CameraPluginTest2_3Activity extends DroidGap { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     super.loadUrl("file:///android_asset/www/index.html"); 
     try{ 
      CustomCamera camera = new CustomCamera(this); 
      appView.addJavascriptInterface(camera, "CustomCamera"); 
      //camera.Cameratest(); 
      //camera.startCamera(50); 
     }catch(Exception ex){ 
      ex.printStackTrace(); 
      Log.e("RapportsError", "error" + ex.toString()); 
     } 
    } 

    public class CustomCamera{ 
     private Context context; 

     public CustomCamera (Context context){ 
      this.context = context; 

     } 

     public void Cameratest() { 
      Log.e("RapportsError", "Cameratest"); 

     } 
     public void startCamera(int quality) 
     { 
      Log.e("RapportsError", "intent"); 
      try{ 

       Intent i = new Intent(context, CameraPreview.class); 

       i.setAction("android.intent.action.PICK"); 
       i.putExtra("quality", quality); 
       startActivityForResult(i, 1); 
       Log.e("RapportsError", "despues de intent"); 
      }catch(Exception ex){ 
       ex.printStackTrace(); 
       Log.e("RapportsError", "error" + ex.toString()); 
      } 
     } 

     protected void onActivityResult(int reqCode, int resCode, Intent intent) 
     { 
      String data;    
      Log.e("RapportsError", "ON ACTIVITY RESULT " + reqCode); 
      //super.onActivityResult(requestCode, resultCode, intent); 
      if (resCode == RESULT_OK) 
      { 
       data = intent.getStringExtra("picture"); 
       Log.e("RapportsError", "error" + data); 
       // Send the graphic back to the class that needs it 
       //launcher.processPicture(data); 
      } 
      else 
      { 
       //launcher.failPicture("Did not complete!"); 
      } 
     } 

    } 

}

主要問題是我能夠拍攝照片，因此該類的調用正在工作，但onActivityResult是不叫。

你有線索嗎？

非常感謝你，再次抱怨我很抱歉，但我不明白問題在哪裏。

你調試嗎？ – Praveenkumar

你檢查過，如果onActivityResult沒有真正調用，或者你的resultCode和/或requestCode與預期的方法不符？ – josephus

有一種可能性，如果一切正確。請在超類中放置onActivityResult，即在DroidGap類中使用logcat消息並在此處註釋 –

好吧，這是我給你的建議改變你的類CustomCamera擴展插件接口的PhoneGap提供。我們處理本地和JavaScript層之間通信的所有小問題。使用addJavascriptInterface時會彈出一些問題，您需要解決這些問題，包括鍵盤顯示重新載入應用程序，界面在某些版本的模擬器上不起作用等。只需使用我們的插件API即可對你來說容易得多。

How to create a Plugin for Android

看看我們的PhoneGap Camera code的src，因爲我們只是推出針對Android的拍照目的，你可以使用相同的方法，但發動你的意圖來代替。

非常感謝，我會嘗試這種方法。 – Gusa

看到你的回答你的問題..你可以得到你的活動回來的插件的方法是確保：

this.cordova.setActivityResultCallback(MyActivity.this);

叫你做startActivityForResult（）之前..打電話。真的讓我感到困擾，似乎沒有人在任何地方回答過。必須自己找出來。

這是什麼「MyActivity」？如果它是一個Android Activity，那麼'void org.apache.cordova.CordovaInterface.setActivityResultCallback（CordovaPlugin arg0）'，該方法採用CordovaPlugin arg。在哪個java文件中，我必須調用此方法，因爲Android Activity沒有'cordova'實例來調用此.cordova。 –

我無法得到onActivityResult工作，直到我已經改變launchMode在AndroidManifest.xml

這一個是不工作：

android:launchMode="singleInstance"

標準和singleTop適合我。

我發現你的清單中沒有launchMode，所以我不確定它會對你的情況有所幫助。但我希望這可以幫助其他任何人解決這個問題。

如果您在您的主要活動onActivityResult（），你必須確保它調用它的父的方法來正確地處理插件：

public class MainActivity extends CordovaActivity { 
        //or 'extends DroidGap' based on Cordova version 

    //... 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) { 
      if (requestCode == MyCustomActivity) { 
        doMyCustomActivity(requestCode); 
      } 
      else { //call onActivityResult() of the plugins 
       super.onActivityResult(requestCode, resultCode, intent); 
      } 
    } 

    //... 
}
