我在將圖像加載到某些設備的屏幕上時遇到了問題。甚至當我解碼圖像時OOM錯誤
所有的屏幕都有一個圖像，但它的相當高的圖像。
以下是在圖像尺寸
人像：
- MDPI：360x1074
- HDPI：540x1611
- xhdpi：720x2148
- xxhdpi：1080x3142
景觀：
- MDPI：640x705
- 華電國際：960x1058
- xhdpi：1280x1410
- xxhdpi：1920x1035
我跟了：https://developer.android.com/training/displaying-bitmaps/load-bitmap.html也是這個http://successmatics.com/blog/loading-large-bitmaps-in-android-ui/，但他們基本上是相同的。
如果我加載一個小得多的圖像說別的縮略圖，它加載得很好。
在OnCreate
mImageView.setImageBitmap(
ImageUtils.decodeSampledBitmapFromResource(getResources(),
R.drawable.image,
ImageUtils.getScreenWidth(getApplicationContext()),
ImageUtils.getScreenHeight(getApplicationContext())));
}
方法加載圖像用於解碼圖像（從上面的2個網址）
public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId, int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(res, resId, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeResource(res, resId, options);
}
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height/2;
final int halfWidth = width/2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight/inSampleSize) >= reqHeight
&& (halfWidth/inSampleSize) >= reqWidth) {
//--------i tried a sample size of 2. was hoping 3 would work---------//
inSampleSize *= 3;
}
}
return inSampleSize;
}
public static int getScreenWidth(Context context) {
DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
return displayMetrics.widthPixels;
}
public static int getScreenHeight(Context context) {
DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
return displayMetrics.heightPixels;
}
任何人都不會有大的圖像解碼更好的辦法，所以我不明白在OOM
或
有什麼錯我的代碼（WHI CH從Android電子自理）

我使用目前唯一的圖像加載庫排球聯網的圖像。這是@Drawable文件中的資源。有2個版本，縱向和橫向（不想拉伸）
感謝
