POObtaining image from android gallery and put in gridview
text
Body
copied!<p>I'm looking for some advice on how to do this.</p> <p>I want to have an activity where the user select from android gallery, then the image will be added into a grid view on the activity. I have successfully implemented both separately, but when I have to combine them I'm at a loss. Grid View tutorial is <a href="http://developer.android.com/guide/topics/ui/layout/gridview.html" rel="nofollow">here</a>. Problem is that grid view tutorial uses images from res/drawable, so the uri i obtain from gallery doesn't exactly work. </p> <p>How should I set the image inside the ImageAdapter class? I've been trying to do imageView.setImageBitmap(bitmap) with the uri address of one of the images in my phone, but it didn't work.</p> <p>I'm thinking of creating an ArrayList of String that contains uri for the images obtained from the gallery. This way i can add, delete, and store the images with ease. </p> <p>Other questions along with this is that if i get the images displayed, will it refresh if i simply call setAdapter again? would delete work automatically if i delete from the source ArrayList?</p> <p>Thank you</p> <p>The following is the code from grid view tut that i edited:</p> <pre><code>public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return imageId.size(); } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(8, 8, 8, 8); } else { imageView = (ImageView) convertView; } Uri targetUri = Uri.parse(tests.get(0)); //tests contains the uri of the photo i'm trying to import from my phone gallery in string form Bitmap bitmap; bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri)); imageView.setImageBitmap(bitmap); return imageView; } } </code></pre>
