我需要解決由位圖大小拋出的OutOfMemory錯誤。圖像質量android
我用這個代碼:
public static Bitmap decodeSampledBitmapFromSDcard(String file,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(file, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth,
reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(file, 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) {
if (width > height) {
inSampleSize = Math.round((float) height/(float) reqHeight);
} else {
inSampleSize = Math.round((float) width/(float) reqWidth);
}
}
return inSampleSize;
}
,但圖像的質量較差。
我需要另一種方式來調整圖像的大小,使其位圖對象很小,並破壞質量。
