    <p>i'm to Overflow and this is my first question here :)</p> <p>I have an gallery, image switcher and button for capturing image from camera. After capturing image into the SD card I want to load the image to the gallery and also show it in the image switch object. for now it work fine with one big question.</p> <p>Why all the images are rotated in the gallery and the image switcher?</p> <p>this is my java code :</p> <pre><code>protected void onCreate(Bundle savedInstanceState) { iSwitcher = (ImageSwitcher) findViewById(R.id.ImageSwitcher01); iSwitcher.setFactory(this); iSwitcher.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in)); iSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out)); setAllPics(); gallery = (Gallery) findViewById(R.id.Gallery01); gallery.setAdapter(new ImageAdapter(this)); gallery.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2, long arg3) { //iSwitcher.setImageResource(pics[arg2]); //iSwitcher.setImageURI(mUrls[arg2]); iSwitcher.setImageDrawable(new BitmapDrawable(getResources(),(bitmap[arg2]))); } }); Button BtnGetPhoto = (Button) this.findViewById(R.id.BtnGetPicture); } public class ImageAdapter extends BaseAdapter { private Context ctx; int mGalleryItemBackground; public ImageAdapter(Context c) { ctx = c; } @Override public int getCount() { return mUrls.length; //return pics.length; } @Override public Object getItem(int arg0) { return arg0; } @Override public long getItemId(int arg0) { return arg0; } @Override public View getView(int arg0, View arg1, ViewGroup arg2) { ImageView iView = new ImageView(ctx); //iView.setImageURI(mUrls[arg0]); iView.setImageDrawable(new BitmapDrawable(getResources(),(bitmap[arg0]))); //iView.setImageResource(pics[arg0]); iView.setScaleType(ImageView.ScaleType.FIT_XY); iView.setLayoutParams(new Gallery.LayoutParams(150, 150)); return iView; } } private void setAllPics(){ File images = new File(PATH); File[] imagelist = images.listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String filename) { return ((filename.endsWith(".jpg"))||(filename.endsWith(".png"))); } }); /* There isn't enough memory to open up more than a couple camera photos */ /* So pre-scale the target bitmap into which the file is decoded */ /* Get the size of the ImageView */ int targetW = 350;//iSwitcher.getWidth(); int targetH = 220;//iSwitcher.getHeight(); BitmapFactory.Options bmOptions = new BitmapFactory.Options(); mFiles = new String[imagelist.length]; int photoW[] = null; int photoH[] = null; int scaleFactor[] = null ; photoW = new int[imagelist.length]; photoH = new int[imagelist.length]; scaleFactor = new int[imagelist.length]; bitmap = new Bitmap[imagelist.length]; for(int i= 0 ; i&lt; imagelist.length; i++) { bmOptions.inJustDecodeBounds = true; mFiles[i] = imagelist[i].getAbsolutePath(); bitmap[i] = BitmapFactory.decodeFile(mFiles[i], bmOptions); /* Get the size of the image */ photoW[i] = bmOptions.outWidth; photoH[i] = bmOptions.outHeight; /* Figure out which way needs to be reduced less */ if((targetW &gt; 0) || (targetH &gt; 0 )) scaleFactor[i] = Math.min(photoW[i]/targetW, photoH[i]/targetH); /* Set bitmap options to scale the image decode target */ bmOptions.inJustDecodeBounds = false; bmOptions.inSampleSize = scaleFactor[i]; bmOptions.inPurgeable = true; try{ /* Decode the JPEG file into a Bitmap */ bitmap[i] = BitmapFactory.decodeFile(mFiles[i], bmOptions); //iSwitcher.setImageDrawable(new BitmapDrawable(getResources(),(bitmap[i]))); } catch (OutOfMemoryError error) { error.printStackTrace(); } } mUrls = new Uri[mFiles.length]; for(int i=0; i &lt; mFiles.length; i++) { mUrls[i] = Uri.parse(mFiles[i]); } } private OnClickListener onClickListener =new OnClickListener(){ // @Override public void onClick(View v) { switch (v.getId()){ case R.id.BtnGetPicture: Intent cameraIntent = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE); String imageFileName = ""; String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); SetPathIfNotExist(PATH); imageFileName = timeStamp + ".jpg"; File image = new File(PATH,imageFileName); Uri uriSavedImage = Uri.fromFile(image); cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage); startActivityForResult(cameraIntent,CAMERA_REQUEST); break; default: break; } } }; protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_REQUEST &amp;&amp; resultCode == RESULT_OK) { setAllPics(); gallery.setAdapter(new ImageAdapter(this)); //Bitmap photo = (Bitmap) data.getExtras().get("data"); //imageView.setImageBitmap(photo); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
