我出现内存不足错误，并不确定如何处理它。我将不胜感激任何帮助！我认为问题在于加载太多图像，但我怎么能避免这种情况呢？我想我只加载了15张卡+背景

您必须使用BitmapFactory.options以较低的分辨率加载图像，否则将导致错误
private void setSuit(int suit){
int suit_num = suit * 13;
int temp;
for(int index = 0; index < this.ib.length; index++) {
temp = suit_num + index;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource (getResources(), card_id[temp],options)
options.inSampleSize = calculateInSampleSize(options,100,100);//100 and 100 whatever you want as scale
options.inJustDecodeBounds = false;
Bitmap yourSelectedImage = BitmapFactory.decodeResource(getResources(),card_id[temp],options);
BitmapDrawable ob = new BitmapDrawable(getResources(), yourSelectedImage)
this.ib[index].setBackgroundDrawable(ob);
}
}
帮助方法
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) {
// Calculate ratios of height and width to requested height and width
final int heightRatio = Math.round((float) height / (float) reqHeight);
final int widthRatio = Math.round((float) width / (float) reqWidth);
// Choose the smallest ratio as inSampleSize value, this will guarantee
// a final image with both dimensions larger than or equal to the
// requested height and width.
inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
}
return inSampleSize;
}
