Question

我正试图在我的程序中获取我的画廊照片。我可以通过使用以下代码来做同样的事情：

要打开图库：

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent,1);

并返回结果并显示所选图像：

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

    switch(requestCode) 
    { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK)
        {  
            Uri selectedImage = imageReturnedIntent.getData();
            InputStream imageStream = null;
            try 
            {
                imageStream = getContentResolver().openInputStream(imageReturnedIntent.getData());
            } 
            catch (FileNotFoundException e) 
            {
                e.printStackTrace();
            }
            selectedContactPicture = BitmapFactory.decodeStream(imageStream);
            setContactPicture.setBackgroundDrawable(new BitmapDrawable(selectedContactPicture));
        }
    }
}

它第一次正常工作。但如果我从我的画廊中选择另一张照片，我的应用程序就会崩溃。请帮助我们解决这个问题。

Answer 1

正如我评论的那样，它没有内存错误，使用inSampleSize()将比例缩放版本的位图加载到内存中

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

    switch(requestCode) 
    { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK)
        {  
            Uri selectedImage = imageReturnedIntent.getData();
            InputStream imageStream = null;
            try 
            {
                imageStream = getContentResolver().openInputStream(imageReturnedIntent.getData());
            } 
            catch (FileNotFoundException e) 
            {
                e.printStackTrace();
            }

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize =8;

            selectedContactPicture = BitmapFactory.decodeStream(imageStream,null,options);
            setContactPicture.setBackgroundDrawable(new BitmapDrawable(selectedContactPicture));
        }
    }
}

Answer 2

像那样使用

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


            if (isCameraOrGallery == 2 && resultData != null) {

                Uri selectedImage = resultData.getData();
                String[] filePathColumn = { MediaStore.Images.Media.DATA };

                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

                uploadImagePath = cursor.getString(columnIndex);
                bitmapUploadImage = BitmapFactory.decodeFile(uploadImagePath);
                profileImageView.setImageBitmap(bitmapUploadImage);
                cursor.close();

        } catch (Exception ex) {

        }
    }
