Android Camera - Save image into a new folder in SD Card
我正在尝试拍照并将其保存到文件中。问题来了，我正在尝试将位图保存到文件中。这是我的代码:
private void takePic() {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 2);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 2) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ImageView test = (ImageView) findViewById(R.id.test);
test.setImageBitmap(photo);
try {
FileOutputStream out = new FileOutputStream("filename");
photo.compress(Bitmap.CompressFormat.JPEG, 90, out);
} catch (Exception e) {
e.printStackTrace();
}
}
}
以及 logcat 中的异常:
