这是我的阵列我viewpager绘制，当我运行它，我会导致内存不足的错误，有没有什么办法来缩小图像尺寸或等？ 我做很多的搜索，但我不能使用它们以及.. 请帮助...

  GalImages =新INT [] { R.drawable.tutorials_01_android_en,R.drawable.tutorials_02_android_en,R.drawable.tutorials_03_android_en,R.drawable.tutorials_04};break

@覆盖
公共对象instantiateItem（ViewGroup中的容器，INT位置）{

    ImageView的ImageView的=新ImageView的（上下文）;
    最终诠释临时=位置;
    imageView.setScaleType（ImageView.ScaleType.CENTER_INSIDE）;
    imageView.setImageResource（GalImages [位置]）;

    （（ViewPager）容器）.addView（ImageView的，0）;
    imageView.setOnClickListener（新OnClickListener（）{
        @覆盖
        公共无效的onClick（查看为arg0）{}
    }）;
    返回ImageView的;
}
 

解决方案

它是一个因为大文件的已知的bug ，它不是。由于Android的高速缓存可绘，其使用几张图片后，会出现内存不足。但我发现另一个方法是，通过跳过了Android默认的缓存系统。

Soultion ： 创建于资产绘制文件夹，然后将图像绘制文件夹中的资产，​​并使用以下函数来获取BitmapDrawable

 公共静态绘制对象getAssetImage（上下文的背景下，字符串文件名）抛出IOException异常{
    AssetManager资产= context.getResources（）getAssets（）。
    InputStream的缓冲区=新的BufferedInputStream（（assets.open（绘制/+文件名+png格式）））;
    点阵位图= BitmapFactory.de codeStream（缓冲区）;
    返回新BitmapDrawable（context.getResources（），位图）;
}

另外的在清单文件中添加以下行

 安卓largeHeap =真
 

this is my drawable in array for my viewpager, when i run it, i results in out of memory error, is there any way to reduce the image size or etc? i do lots of search but i can't use them as well.. please help...

GalImages = new int[] { R.drawable.tutorials_01_android_en,R.drawable.tutorials_02_android_en,R.drawable.tutorials_03_android_en,R.drawable.tutorials_04};break

@Override
public Object instantiateItem(ViewGroup container, int position) {

    ImageView imageView = new ImageView(context);
    final int temp = position;
    imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
    imageView.setImageResource(GalImages[position]);

    ((ViewPager) container).addView(imageView, 0);
    imageView.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {}
    });
    return imageView;
}

Its a known bug, its not because of large files. Since Android Caches the Drawables, its going out of memory after using few images. But i found alternate way for it, by skipping the android default cache system.

Soultion: Create a drawable folder in Assets and move the images to "drawable" folder in assets and use the following function to get BitmapDrawable

public static Drawable getAssetImage(Context context, String filename) throws IOException {
    AssetManager assets = context.getResources().getAssets();
    InputStream buffer = new BufferedInputStream((assets.open("drawable/" + filename + ".png")));
    Bitmap bitmap = BitmapFactory.decodeStream(buffer);
    return new BitmapDrawable(context.getResources(), bitmap);
}

Also that add the line below in your manifest file

android:largeHeap="true"
