Question

我有一个带有大量片段的ViewPagerActivity（滑动视图）。每个片段都包含一个imageView。有时，当我在这些片段之间导航时，我有一个错误：

代码：

private void loadNewCourse(int times) {

        Display display = this.getActivity().getWindowManager().getDefaultDisplay();

        int height = display.getHeight();

        mImageSwitcher.getLayoutParams().height=height;

        barLayout.setBackgroundColor(Color.rgb(cours.getCategorie()
                .getCouleur().getR(), cours.getCategorie().getCouleur().getV(),
                cours.getCategorie().getCouleur().getB()));
        // Ajout du titre de la progression Ã  la fenetre
        titreCours = (TextView) barLayout.findViewById(R.id.titreCours);
        titreCours.setText(cours.getTitre());
        mImages = JpgViewerTools.loadPicturesFromSDCardExcept(absolutePath + File.separator
                + cours.getId());

        slidesSize = mImages.size();

        mDifferentSlidesSize = ViewPagerActivity.slidesSize;
        displaySlidesCount();
        if (times == 0) {
            barState = BarState.ELLAPSED;
        } else
            barState = BarState.ELLAPSED;
        mImageSwitcher.setImageURI(Uri.fromFile(new File(mImages
                .get(getArguments().getInt("position")))));

        state = setState(getArguments().getInt("position"));
    }

我该如何解决这个问题？感谢

使用寻呼机时，所有图像都保存在内存中。如果您快速切换页面可能会出现一个问题。要解决此问题，请在读取滑动之间添加一点延迟。其次，如果文件很大，那么随着堆栈的累积，你会随着时间的推移收到这个错误。考虑减少图像大小或在一定数量后删除页面，并在以后需要时添加它们。最后，如果您使用模拟器测试您的设备，您可能只需要增加模拟器的内存。

使用setImageUri的OutOfMemory
