Question

I am trying to get an image that I put into an image view. This is my approach:

// Get the image in the image view
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    Bitmap myBitmap = mImageView.getDrawingCache();
    myBitmap.compress(CompressFormat.PNG, 0, outputStream);

Then I want to insert it into a database:

mDbHelper.createReminder(outputStream);

The DatabaseAdapter looks like this:

public long createReminder(ByteArrayOutputStream outputStream) {
    ContentValues initialValues = new ContentValues();
    initialValues.put(KEY_IMAGE, outputStream.toByteArray());        
    return mDb.insert(DATABASE_TABLE, null, initialValues);
}

When I tried it the app crashed. I think that my statements are somehow faulty. Any ideas???

Answer 1

Drawable drawable = mImageView.getDrawable();
if (drawable instanceof BitmapDrawable) {
    BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
    Bitmap bitmap = bitmapDrawable.getBitmap();
}
