Bitmap yourBitmap;Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);
resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

public Bitmap resizeBitmap(String photoPath, int targetW, int targetH) {
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(photoPath, bmOptions);
int photoW = bmOptions.outWidth;
int photoH = bmOptions.outHeight;
int scaleFactor = 1;
if ((targetW > 0) || (targetH > 0)) {
scaleFactor = Math.min(photoW/targetW, photoH/targetH);
}
bmOptions.inJustDecodeBounds = false;
bmOptions.inSampleSize = scaleFactor;
bmOptions.inPurgeable = true; //Deprecated API 21
return BitmapFactory.decodeFile(photoPath, bmOptions); }- 3 回答
