I have been trying to understand how the SQLite DB works in android. i made a simple app that uses the camera to take a photo and display it to the screen... what id like to do is also store a description of the photo too--and the best way i know how to do that is with a db. But I'm having trouble understanding how to store the image.
the image from the camera is kind of large, so i don't really want store it in the DB as a blob. I have been doing some digging on storing the file path as a text field in the database--and i think the SQL is right to store the path. this is from my DBAdapter class:
private static final String DATABASE_CREATE_SQL =
"create table " + DATABASE_TABLE
+ " (" + KEY_ROWID + " integer primary key autoincrement, "
+ KEY_USERNAME + " text, "
+ KEY_DATE + " text, "
+ KEY_PHOTO_DESCRIPTION + " text, "
+ KEY_IMAGE_PATH + " text"
+ ");";
insert method:
public long insertRow(String username, String date, String photoDesc, String imagePath) {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_USERNAME, username);
initialValues.put(KEY_DATE, date);
initialValues.put(KEY_PHOTO_DESCRIPTION, photoDesc);
initialValues.put(KEY_IMAGE_PATH, imagePath);
// Insert it into the database.
return db.insert(DATABASE_TABLE, null, initialValues);
}
then in my MainActivity--the onActivityResult() for receiving the image from the camera:
private void receiveImage(int resultCode) {
if(resultCode == Activity.RESULT_OK) {
getContentResolver().notifyChange(imageUri, null);
ContentResolver contentResolver = getContentResolver();
try {
imageBitmap = MediaStore.Images.Media.getBitmap(contentResolver, imageUri);
} catch(Exception e) {
Toast.makeText(TakePhotoActivity.this, "failed to load", Toast.LENGTH_LONG).show();
Log.e(LOG_TAG, e.toString());
}
}
}
this is how i am adding the row to the database:
public void onClick_AddRecord(View v) {
long newId = myDb.insertRow("User", "00/00/0000",
"image description", imageUri);
populateListViewFromDB();
}
now the issue-- if i create an activity to view all the information stored in a row, how do i access the image and assign it to an ImageView?
Please check if it helps:
ImageView.setImageURI()
to bind image URI with imageView.
