onActivityResult不起作用

目前正在從圖庫/ cammera中獲取圖像並將其設置在imageview上的任務，並且我正在使用tabgroup activity.in onActivityResult未調用。請檢查我的代碼，並請給我一些解決方案onActivityResult不起作用

public class Create_Event extends BaseActivity{ 
    ImageView prof; 
    String imagepath; 
    Button next; 
    private static int RESULT_LOAD_IMAGE = 1; 
    @SuppressLint("HandlerLeak") 
    public void onCreate(Bundle savedInstanceState) { 
     setLayoutId(this, R.layout.createevent); 
     super.onCreate(savedInstanceState); 
     mHandler = new Handler() 
     { 
     @Override 
     public void handleMessage(Message msg) { 
      super.handleMessage(msg); 

      switch (msg.what) { 
      case Constants.MSG_CHOOSE_PHOTO: { 
        Intent i = new Intent(
          Intent.ACTION_PICK, 
          android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
        // startActivityForResult(i,Constants.MSG_CHOOSE_PHOTO); 
         System.out.println("fghdfgldgdjlgjdjgldfjgdfgdfjgl;f"); 
          startActivityForResult(i,Constants.MSG_CHOOSE_PHOTO); 
      } 
       break; 
     } 
     } 
       }; 

     initview(); 


    } 
    public void initview() { 
     prof=(ImageView)findViewById(R.id.eventimg); 
     prof.setOnClickListener(this); 
     next =(Button)findViewById(R.id.button1); 
     next.setOnClickListener(this); 
      if(Constants.getPicture_path().toString().length()>0) 
      { 
      prof.setImageBitmap(BitmapFactory.decodeFile(Constants.getPicture_path().toString())); 
      } 


      registerForContextMenu(prof); 
    } 

     public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) { 
      super.onCreateContextMenu(menu, v, menuInfo); 
      menu.setHeaderTitle("Choose Image from"); 
      menu.add(0, v.getId(), 0, "Gallery"); 
      menu.add(0, v.getId(), 0, "camera"); 
      }

     {

      } 
      else if(item.getTitle()=="camera") 
      { 
       function2(item.getItemId()); 
      } 
      else 
      { 
      return false; 
      } 
      return true; 
     } 
     private void function1(int itemId) 
     { 
      mHandler.sendEmptyMessage(Constants.MSG_CHOOSE_PHOTO); 




     } 
     private void function2(int itemId) 
     { 
      Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 
      intent.putExtra(MediaStore.EXTRA_OUTPUT, "/mnt/sdcard/profile_image.jpg"); 
      imagepath="/mnt/sdcard/montacts_profile_image.jpg"; 
      startActivityForResult(intent, 1); 
     } 








     @Override 
     public void onActivityResult(int requestCode, int resultCode, Intent data) { 
      super.onActivityResult(requestCode, resultCode, data); 
       System.out.println("eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee;f"); 

      if (requestCode == Constants.MSG_CHOOSE_PHOTO && resultCode == RESULT_OK && null != data) { 
       Uri selectedImage = data.getData(); 
       String[] filePathColumn = { MediaStore.Images.Media.DATA }; 

       Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null); 
       cursor.moveToFirst(); 
       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
       String picturePath = cursor.getString(columnIndex); 
       cursor.close(); 

       imagepath=picturePath; 

       Constants.setPicture_path(picturePath); 

        // Bitmap b = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length) 
         //profileImage.setImageBitmap(Bitmap.createScaledBitmap(b, 120, 120, false)); 
       prof.setImageBitmap(BitmapFactory.decodeFile(picturePath)); 

        } 
      else if(requestCode == 1){ 

       if(data != null) 
       { 
        Bitmap photo = (Bitmap) data.getExtras().get("data");

        prof.setImageBitmap(photo); 
       } 
       else 
       { 

       } 

      } 

    } 


    public void onClick(View view) { 
     int viewId = view.getId(); 
     switch (viewId) { 
     case R.id.eventimg: 
     { 
      //Intent i=new Intent(this,New_imgsel.class); 
      //startActivity(i); 

     } 
      break; 
     case R.id.button1: 
     { 


     } 
      break; 
     } 
    }

if(item.getTitle()=="Gallery") 
{ 
     function1(item.getItemId()); 
} 
else if(item.getTitle()=="camera") 
{ 
     function2(item.getItemId()); 
}

功能1和功能2從不叫，因爲你是在錯誤的道路字符串比較。你必須使用equals或eqaulsIgnoreCase

if(item.getTitle().equalsIgnoreCase("Gallery")) 
{ 
     function1(item.getItemId()); 
} 
else if(item.getTitle().equalsIgnoreCase("camera")) 
{ 
     function2(item.getItemId()); 
}

與==你比較從父活動絃樂

它不工作，我按照你所提到的那樣進行修改。也可以輸入處理程序並打印出System.out.println（「fghdfgldgdjlgjdjgldfjgdfgdfjgl; f」）;並從此它調用onActivityResult，但它不在這裏調用，是我的選項卡組activity.plz幫助我/ –

什麼是「它不工作」的意思。我懷疑我可以工作之前，你apprup改變我建議你 – Blackbelt

sorry.is有任何方法來解決這個問題，請給我一些建議。 –

呼叫startActivityForResult的地址，趕上結果在那裏。
