OnActivityResult 在 TabActivityGroup 中不起作用? [英] OnActivityResult is not working in TabActivityGroup?

问题描述

我使用 Tab Activity 作为主 Activity，其中有 4 个选项卡.一个选项卡是活动组，它具有三个按钮.每个按钮是一个活动.我在其中一项活动中使用相机.我知道它可以工作，因为我已经检查了存储卡中的图像已保存，但它没有调用 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ContentView

This is to display the ContentView

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

此代码用于拍摄图像

             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的结果

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;
     }
 }

谢谢大家的帮助

推荐答案

我已经解决了我的问题.请看下面我的回答，

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

我终于想通了/记住了这个问题是因为Android只允许嵌套的子活动层......即子活动不能嵌套子活动.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:

从您的子活动中调用 getParent().startActivityForResult()您的父母(活动组)将能够处理 onActivityResult.所以我创建了一个ActivityGroup的子类并处理了这个onActivityResult.如果需要，您可以将该结果重新路由回子活动.只需通过 getLocalActivityManager().getCurrentActivity() 获取当前活动.我的子活动继承自自定义活动，因此我在该子类中添加了 handleActivityResult(requestCode, resultCode, data) 供 ActivityGroup 调用.

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.

用确切代码回答上述问题

Answer for the above question with exact code

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

这是ActivityGroup类，您必须在其中为所有子活动定义onActivityResult，

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);   
            }

        }

在子活动中，您必须设置如下视图

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
    }
