    copied!<p>My Activity consists of GridView which holds 40+ elements. After starting activity user could see maximum 15 items (3 rows, 5 items in each row). I wrote in getView() body to pass to the LogCat number of getting View:</p> <pre><code>Log.i("getView()", "GETTING VIEW_POSITION[" + String.valueOf(position) + "]" + (convertView != null?convertView.toString():"null")); </code></pre> <p>After launching my app I get such log:</p> <pre><code>02-09 14:34:56.900: INFO/getView()(388): GETTING VIEW_POSITION[0]null 02-09 14:34:57.300: INFO/getView()(388): GETTING VIEW_POSITION[0]android.widget.FrameLayout@44c7a9c0 02-09 14:34:57.300: INFO/getView()(388): GETTING VIEW_POSITION[1]null 02-09 14:34:57.400: INFO/getView()(388): GETTING VIEW_POSITION[2]null 02-09 14:34:57.510: INFO/getView()(388): GETTING VIEW_POSITION[3]null 02-09 14:34:57.620: INFO/getView()(388): GETTING VIEW_POSITION[4]null 02-09 14:34:57.720: INFO/getView()(388): GETTING VIEW_POSITION[5]null 02-09 14:34:57.840: INFO/getView()(388): GETTING VIEW_POSITION[6]null 02-09 14:34:57.930: INFO/getView()(388): GETTING VIEW_POSITION[7]null 02-09 14:34:58.273: DEBUG/dalvikvm(388): GC freed 3530 objects / 322744 bytes in 270ms 02-09 14:34:58.280: INFO/getView()(388): GETTING VIEW_POSITION[8]null 02-09 14:34:58.300: INFO/getView()(388): GETTING VIEW_POSITION[9]null 02-09 14:34:58.320: INFO/getView()(388): GETTING VIEW_POSITION[10]null 02-09 14:34:58.340: INFO/getView()(388): GETTING VIEW_POSITION[11]null 02-09 14:34:58.360: INFO/getView()(388): GETTING VIEW_POSITION[12]null 02-09 14:34:58.380: INFO/getView()(388): GETTING VIEW_POSITION[13]null 02-09 14:34:58.400: INFO/getView()(388): GETTING VIEW_POSITION[14]null 02-09 14:34:59.220: INFO/getView()(388): GETTING VIEW_POSITION[0]null 02-09 14:34:59.490: INFO/getView()(388): GETTING VIEW_POSITION[0]android.widget.FrameLayout@44c69ef0 </code></pre> <p>I also red <a href="http://code.google.com/p/android/issues/detail?id=12889">this</a> post about such kind of issue. But My GridView's height in XML description set as fill parent:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/grid" android:layout_width="fill_parent" android:layout_height="fill_parent" android:numColumns="auto_fit" android:horizontalSpacing="10dp" android:verticalSpacing="10dp" android:columnWidth="140dp" android:gravity="center" android:scrollbars="none" /&gt; </code></pre> <p>And finally to remove all doubts, here is my Adapter code:</p> <pre><code>public class ImageAdapter extends BaseAdapter { private Activity activity; private LayoutInflater inflater = null; private ArrayList&lt;Photo&gt; photoes; public ImageAdapter(Activity a, ArrayList&lt;Photo&gt; pictures) { photoes = pictures; activity = a; inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { Log.i("getView()", "GETTING VIEW_POSITION[" + String.valueOf(position) + "]" + (convertView != null?convertView.toString():"null")); View mViewSlice = convertView; if(convertView == null) { mViewSlice = inflater.inflate(R.layout.photo_preview, null); ((TextView) mViewSlice.findViewById(R.id.name_of_photo)).setText(photoes.get(position).getName()); mViewSlice.setPadding(5, 5, 5, 5); mViewSlice.setLayoutParams(new GridView.LayoutParams(-2, -2)); } return mViewSlice; } @Override public int getCount() { return photoes.size(); } @Override public Object getItem(int position) { return photoes.get(position); } @Override public long getItemId(int position) { return position; } } </code></pre> <p>I hope somebody will respond at my problem and will help me to solve it.</p> <p>Waiting for your suggestions. Alex.</p>
