您好我想从手机内存加载图片并将其放在ImageView上。这是我加载图片的代码:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
mImageCaptureUri = selectedImage;
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(picturePath, options);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
imageView.setScaleType(ScaleType.FIT_XY);
isBackgroundChange = true;
}
}
此代码正常运行,但每次加载大图像(分辨率)时,应用程序都会关闭。
