问题
I have an camera Activity like this:
public void startCamera()
{
Log.d("ANDRO_CAMERA", "Starting camera on the phone...");
String fileName = "testphoto.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,
"Image capture by camera");
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, IMAGE_CAPTURE);
}
What should I do to save this image to a SQLite database?
I have code like this:
fileName = helper.getKdStore(c) + "_" + System.currentTimeMillis() + ".jpg";
_path = Environment.getExternalStorageDirectory().toString() + "/DCIM/Camera/" + fileName;
In start camera:
Cursor c = helper.getById(almagId);
c.moveToFirst();
File file = new File(_path, null);
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
Uri outputFileUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, IMAGE_CAPTURE);
System.out.println(file);
Dbhelper helper = new Dbhelper(this);
SQLiteDatabase db = helper.getWritableDatabase();
db.execSQL("update alfamapp set gambar ='"+file+"' where kdstore='"+helper.getKdStore(c)+"'");
db.close();
helper.close();
System.out.println(db);
and I create method public void load() to display my image:
detGam.setImageDrawable(Drawable.createFromPath(_path));
but my application can't display the image. Thank you for your help.
回答1:
Saving Image in to sqlite is bad idea, however if you still want to go further, there here is code
public static void insertPicture(byte[] data)
{
SQLiteDatabase db = thisAct.openOrCreateDatabase(ConstantCodes.IMAGE_DATABASE, 2, null);
ContentValues values = new ContentValues(1);
values.put("photo", data);
db.insert("photos", null, values);
db.close();
}
