Question

我使用 Tab 活动作为主要活动, 它有 4 个制表符。一个制表符是活动组, 有 3 个按钮。每个按钮都是一个活动。我在其中一项活动中使用相机。我知道它的工作, 因为我在存储卡中检查了保存的图像, 但是它没有使用 OnactutionAgress () 方法。

这是要显示内容View

    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);

这是活动结果

     @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;
     }
 }

谢谢你的帮忙伙计们

我的问题解决了,请见我下面的答案

我终于想通/记得, 问题是因为Android只允许一个嵌巢层的亚活性..., 即亚活性, 无法嵌巢子活性。要解决这个问题:

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.

以精确代码回答上述问题

< 强度 > 活动组- gt; 准活动 & gt; on 积极性Result- gt; 活动组( 积极性Result) - gt; 辅助活动组( 积极性Result)

这是活动组类, 您必须在其中定义所有子活动的“ 活动结果”,

@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,您必须设置以下视图

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

然后在关于活动成果的分活动中()

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