    <p>I have pictures in my Gallery that are both landscape or portrait. The show up correctly in the Gallery application. When I use an intent to select the picture from the gallery I get a URI back. But before I display the picture how do I know if the picture is portrait or landscape?</p> <p>My application selects pictures using an Intent like this:</p> <pre><code> private OnClickListener btnChooseFromLibraryListener = new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType("image/*"); startActivityForResult(intent, REQ_CODE_PICK_IMAGE); } }; </code></pre> <p>Here is how I get the intent back:</p> <pre><code> protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { super.onActivityResult(requestCode, resultCode, imageReturnedIntent); switch(requestCode) { case REQ_CODE_PICK_IMAGE: if(resultCode == RESULT_OK){ Uri selectedImage = imageReturnedIntent.getData(); String[] filePathColumn = {MediaStore.Images.Media.DATA}; Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String filePath = cursor.getString(columnIndex); cursor.close(); SetPicture(filePath); } } } private void SetPicture(String filePath) { Bitmap bm = BitmapFactory.decodeFile(filePath); Log.d("TW", "Picture Path:" + filePath); String size = String.format("Width:%d Height:%d", bm.getWidth(), bm.getHeight()); Log.d("TW", size); ivPicture.setImageBitmap(bm); ui.setLastPicture(filePath); } </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.
