OnActivityResult不是工作在TabActivityGroup？ [英] OnActivityResult is not working in TabActivityGroup?

问题描述

我使用的选项卡的活动中，它有4个选项卡的主要活动。一个选项卡是活动组有三个按钮。每个按钮是一个活动。我使用的相机在这些活动之一。我知道它的工作，因为我在存储卡中的图像被保存已经检查了，但它并没有调用Onactivityresult（）方法。

I am using Tab Activity as a main Activity in which it has 4 tabs. One tab is Activity Group which has three buttons. Each button is one activity. I am using camera in one of those activity. I know its working because i have checked in the memory card the image get saved, but it doesn't calling the Onactivityresult() method.

这是显示内容查看

    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.enter_expenses, null);
    this.setContentView(viewToLoad);            

这code是用来取图片

This code is used to take the image

             dbimgguid = UUID.randomUUID();
             imagename =dbimgguid.toString();
             Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
             photo = new File(Environment.getExternalStorageDirectory(), "Expenses"+imagename+".jpg");
             intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photo));
             imageurl = Uri.fromFile(photo); 
             startActivityForResult(intent, CAMERA_RECEIPTREQUEST); 

这是onactivity结果

This is onactivity result

     @Override
     protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
     super.onActivityResult(requestCode, resultCode, data);  
     System.out.println(requestCode);
     System.out.println(resultCode);
     switch(requestCode)
     {
     case CAMERA_RECEIPTREQUEST:  
         if(resultCode== Activity.RESULT_OK)
         {
         //Toast.makeText(this, "Receipt Image Saved", Toast.LENGTH_SHORT).show();
         BitmapFactory.Options options = new BitmapFactory.Options();
         options.inSampleSize = 8;
         //ImageView jpgView = (ImageView)findViewById(R.id.imageView1);
         Bitmap receipt = BitmapFactory.decodeFile(photo.toString(),options);  
         String image = "Expenses"+imagename+".jpg"; 
         Intent imagepass = new Intent(ExpensesActivity.this,ReviewReceiptImage.class);
         imagepass.putExtra("receipt", receipt);
         imagepass.putExtra("imagename", image);
         startActivityForResult(imagepass, CAMERA_CONFIRMRECEIPT); 
         Toast.makeText(this, "Receipt Image Saved", Toast.LENGTH_SHORT).show();
         }

     case CAMERA_CONFIRMRECEIPT:

         Toast.makeText(this, "Receipt Image Saved", Toast.LENGTH_SHORT).show();
         if(resultCode == CAMERA_CONFIRMRECEIPT)
         {
             take_receipt.setEnabled(false);
             take_receipt.setVisibility(View.GONE);
             show_receipt.setEnabled(true);
             show_receipt.setVisibility(View.VISIBLE);
         } 
         break;
     }
 }

推荐答案

我已经解决了我的issue.Please看到我的回答如下，

I have solved my issue.Please see my answer below,

我终于想通了/还记得，这个问题是因为Android将只允许子活动嵌套层...即子活动不能嵌套子activitites。要解决这个问题：

I finally figured out/remembered that the issue is because Android will only allow a nested layer of sub-activities...ie sub-activities can't nest sub-activitites. To solve this:

呼叫的getParent（）。startActivityForResult（）从子活动 你的父母（在的ActivityGroup）将能够处理onActivityResult。因此，我创建的ActivityGroup的子类，这样处理onActivityResult。 您可以重新路由结果返回给子活动，如果你需要。刚刚获得由当前活动getLocalActivityManager（）。getCurrentActivity（）。我的子活动从一个自定义活动继承，所以我增加了一个 handleActivityResult（要求code，因此code，数据）在子类中的ActivityGroup打电话

call getParent().startActivityForResult() from your sub-activity your parent (the activitygroup) will be able to handle the onActivityResult. So I created a subclass of ActivityGroup and handled this onActivityResult. You can re-route that result back to the sub-activity if you need to. Just get the current activity by getLocalActivityManager().getCurrentActivity() . My sub-activities inherit from a custom activity so I added a handleActivityResult(requestCode, resultCode, data) in that subclass for the ActivityGroup to call.

答与精确code中的上述问题

Answer for the above question with exact code

ActivityGroup->SubActivities->onActivityResult->ActivityGroup(onActivityResult)->subActivity(onActivityResult)

这是的ActivityGroup类中，你必须定义onActivityResult所有的子活动，

This is the ActivityGroup Class in which you have to define onActivityResult for all sub-activities,

@Override
public void onActivityResult(int requestCode,int resultCode, Intent data)
{

         switch(requestCode)
            {

            case CAMERA_RECEIPTREQUEST:   
            if(resultCode == Activity.RESULT_OK)
            {
            ExpensesActivity activity = (ExpensesActivity) getLocalActivityManager().getCurrentActivity();
            activity.onActivityResult(requestCode, resultCode, data);
            }
            break;

            case CAMERA_CONFIRMRECEIPT:
            ExpensesActivity activity1 = (ExpensesActivity) getLocalActivityManager().getCurrentActivity();
            activity1.onActivityResult(requestCode, resultCode, data);   
            }

        }

在小组活动中，你必须设置看法如下

In Sub Activity, you have to set the view as below

    View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.enter_time, null);
    this.setContentView(viewToLoad);

然后在子活动onActivityResulty（）

Then in Sub- Activity onActivityResulty()

    @Override
    public void onActivityResult(int requestCode,int resultCode, Intent data)
    {
     //Some Code
    }
