回收ImageViews以避免OutOfMemoryError [英] Recycle ImageViews to avoid OutOfMemoryError

问题描述

在某些手机（特别是三星）中，应用程序会出现OutOfMemory错误。

In some phones (especially Samsungs), the application gives an error of OutOfMemory.

我使用带有4个ImageView的ViewFlipper，它们会在教程中显示。

I use a ViewFlipper with 4 ImageViews which they are shown in a tutorial.

我发现无法解决错误或回收图像视图。

I have found no way to remedy the error or recycle imageviews.

这是管理ViewFlipper的方法：

This is the method that manages the ViewFlipper:

private void changeBackground(int position) {

    switch (position) {

        case 1:
            mViewFlipper.setDisplayedChild(1);
            mViewFlipper.setInAnimation(getActivity(), R.anim.anim_clockwise_onboarding);
            mViewFlipper.setOutAnimation(getActivity(), R.anim.anim_clockwise_inverse_onboarding);
            break;

        case 2:
            mViewFlipper.setDisplayedChild(2);
            mViewFlipper.setInAnimation(getActivity(), R.anim.anim_clockwise_onboarding);
            mViewFlipper.setOutAnimation(getActivity(), R.anim.anim_clockwise_inverse_onboarding);
            break;

        case 3:
            mViewFlipper.setDisplayedChild(3);
            mViewFlipper.setInAnimation(getActivity(), R.anim.anim_clockwise_onboarding);
            mViewFlipper.setOutAnimation(getActivity(), R.anim.anim_clockwise_inverse_onboarding);
            break;

        default:
            mViewFlipper.setDisplayedChild(0);
            mViewFlipper.setInAnimation(getActivity(), R.anim.anim_clockwise_onboarding);
            mViewFlipper.setOutAnimation(getActivity(), R.anim.anim_clockwise_inverse_onboarding);
            break;

    }

}

方法是每次在ViewPager中更改页面时都会调用。

The method is called each time you change pages in a ViewPager.

@Override
public void onPageSelected(int position) {
       changeBackground(mViewPager.getCurrentItem());
}

如果有任何想法请帮助我，提前致谢。

If any have idea please help me, Thanks in advance.

推荐答案

为此你需要使用Image loader库来加载图像。
您可以使用：

For that you need to use Image loader library for loading images. You can use :

1. 通用图片加载器


2. Picasso


3. Glide

此库用于位图内存管理，使用此库后，您没有遇到OutOfMemoryError异常。

This library uses for bitmap memory management and after using this library you didn't face OutOfMemoryError exeption.
