这是我的代码
BitmapDrawable bmpDrawable = null;
// try to retrieve the image using the data from the intent
Cursor cursor = getContentResolver().query(data.getData(),
null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
String fileSrc = cursor.getString(idx);
bitmap = BitmapFactory.decodeFile(fileSrc); // load
bitmap = Bitmap.createScaledBitmap(bitmap,
100, 100, false);// this is line 136
img_logo.setImageBitmap(bitmap);
} else {
bmpDrawable = new BitmapDrawable(getResources(), data
.getData().getPath());
img_logo.setImageDrawable(bmpDrawable);
}
