Gallery OnActivityResult在TabActivity中不起作用

Question

我得到了我的代碼問題，我想從圖庫中獲取圖像並在我的xml佈局中顯示它（問題是當我點擊按鈕它會去圖庫但當我選擇它只是Gees的另一個選項卡中的圖片）

1）我的主類創建標籤

public class MainUser extends TabActivit 
    ..... 

TabSpec tabSpec10 = mTabHost.newTabSpec("tab_test1"); 
     tabSpec10.setIndicator("Report incident "); 
     Context ctx10 = this.getApplicationContext(); 
     Intent i10 = new Intent(ctx10, ucrimereport.class); 
     tabSpec10.setContent(i10); 
     mTabHost.addTab(tabSpec10); 

2）這是我在哪裏製作和調用庫

public class ucrimereport extends Activity implements OnClickListener,OnItemSelectedListener { 
    private static final int IMAGE = 1; 

@Override 

    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.ureport); 
......... 
     gallary = (ImageButton)findViewById(R.id.sdpic_button); 

gallary.setOnClickListener(new OnClickListener() { 
     public void onClick(View v) { 
      // gallary 
      Intent gallery = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
      startActivityForResult(gallery, IMAGE); 

     } 
    }); 

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if(resultCode==RESULT_OK && requestCode==IMAGE){ 
     Uri selectedImage=data.getData(); 
     String path=getPath(selectedImage); 

     Bitmap bitmapImage=BitmapFactory.decodeFile(path); 
     //ImageView image=(ImageView)findViewById(R.id.image); 
     image.setImageBitmap(bitmapImage); 

     } 
    } 

    public String getPath(Uri uri){ 
     String[] filePathColumn={MediaStore.Images.Media.DATA}; 

     Cursor cursor=getContentResolver().query(uri, filePathColumn, null, null, null); 
     cursor.moveToFirst(); 
     int columnIndex=cursor.getColumnIndex(filePathColumn[0]); 

     return cursor.getString(columnIndex); 
    }

請嘗試驗證碼。

public class ImageGalleryDemoActivity extends Activity {  
    private static int RESULT_LOAD_IMAGE = 1; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture); 
     buttonLoadImage.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       Intent i = new Intent(
         Intent.ACTION_PICK, 
         android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 

       startActivityForResult(i, RESULT_LOAD_IMAGE); 
      } 
     }); 
    } 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (requestCode == RESULT_LOAD_IMAGE && 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(); 

      ImageView imageView = (ImageView) findViewById(R.id.imgView); 
      imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); 
     } 
    } 
}
